05/05/2008 6 Issue A

1.2. Description

1.2.1. Introduction

Refer to Figure 1.

The SNH and SNV type rotary blowers have two built-in tri-lobed rotors (8), one of which is driven by the drive shaft (5) and the other is maintained in stroke by synchronizing gears. The synchronizing gears, as well as the roller bearings of the rotors and the drive shaft, are lubricated with oil stored in the housings on the drive-side (4) and opposite the control (12).

The SN blowers are positive displacement blowers, cooled by ambient air.

The blowers are supplied in bareshaft form. You must connect your own coupling or belt drive system (see Section 3.8) to the drive shaft in order to operate the blower.

The blowers are available in two different versions:

SNH version blowers, which are installed horizontally, and provide for a vertical gas flow through the blower.

SNV version blowers, which are installed vertically, and provide for a horizontal gas flow through the blower.

Refer to Section 2.8 for the Item Numbers of the different blower versions.

1.2.2. Standard/ATEX-compliant blowers The following positive displacement blower models are available:

Standard blowers: these are suitable only for the pumping/compression of surrounding air, as well as gas, gaseous mixtures and uninflammable dust.

Standard/ATEX-compliant blowers Category 2 or 3 ATEX-compliant blowers: these comply with the ATEX European directive and are suitable for the pumping/compression of gas, gaseous mixtures and uninflammable or flammable dust. For more information, refer to sections 1.2.4 and 1.3.

1.2.3. ATEX certification and compliance (ATEX-compliant blowers only) All the category 2 ATEX-compliant blowers have been specially developed to pump/compress a flammable atmosphere, classified as an internal zone 1 or 2, without needing to install protective devices such as flame guards.

The blowers have also been designed to function in an exterior flammable environment classified as zone 1 or 2. The blowers are certified (according to directive 94/9/CE) as category 2 or 3 equipment according to the European ATEX directive. For this certification to be valid, blowers must be installed and used exactly as specified in this manual.

The blowers have been designed following the rules of safety construction, which ensure the elimination of potential sources of ignition, even if there are disturbances and frequent malfunctions.

The blowers are suitable for pumping/compressing a wide range of flammable gasses and vapors, subject to the restrictions specified in section 1.2.6.

05/05/2008 7 Issue A

1.2.4. ATEX Directive (94/9/CE): Europe only (ATEX-compliant blowers only).

1.2.4.1 Introduction The category 2 or 3 ATEX-compliant blowers must be built into a larger system whose internal atmosphere is classified as zone 1 or 2. These systems will be certified according to the above-mentioned directive and must have an ATEX identification label affixed to them.

For the certification to be valid, the blowers must be installed exactly as specified in this manual.

The blowers carry an ATEX identification label which contains the following information:

II 2 G/D c, IIB T3 160oC X internal

II 2 G/D c, IIB T3 160oC X external

Table 0 explains the notations used on the label.

specifies that blower can be used in a potentially explosive atmosphere

II Group II equipment (non mining)

2 Category 2 equipment

G/D Suitable for potentially explosive internal gaseous/dusty atmospheres

C Conforms to the safety construction protection strategy

IIB Suitable for pumping group IIB gas

T3 160C Spontaneous combustion temperature of gases /dust (see section 1.2.4.2)

X Indicates the need for specific operating conditions in order to guarantee compliance with the temperature classification (see section 1.2.4.2).

Table 1- ATEX classification notation

1.2.4.2 Temperature classification

The temperature classification that applies to the category 2 or 3 ATEX-compliant blowers refers to the spontaneous combustion temperature of flammable materials that can be pumped/compressed, or that may be present in the external atmosphere.

WARNING

The category 1 or 3 ATEX-compliant blowers must be operated according to the procedures described in section 4 in order to prevent exceeding the temperature

classification.

05/05/2008 8 Issue A

The temperature classification of the ATEX-compliant blowers is T3 160 o C (320 o F) for gaseous/dusty internal and external atmospheres. For dusty external atmospheres, you should provide an appropriate security margin for using the blower according to the type/composition of the dust and the thickness of the dust layers.

Note: the ATEX-compliant blowers cannot function (under pressure) at a differential pressure greater than the values specified in tables 2 to 15, at the risk of exceeding the temperature classification.

Refer to section 2 of this manual for the required operating conditions of the blowers.

1.2.5. Normal operations

The category 2 or 3 ATEX-compliant blowers are based on the safety construction principle for the safe pumping/compressing of flammable gasses and vapors. In order to abide by the safety construction requirements, it is your responsibility to prevent any particles of more than 25 mm from penetrating blower.

If such a risk is not present, the blower can be used to pump/compress gas group IIB flammable materials (example given in table 2), under normal operating conditions as set forth in this manual.

The materials from which the positive displacement blowers are constructed are specified in section 2.7. Before using blower, you must ensure that these materials are compatible with the gasses and vapors that could be present in the external atmosphere.

1.2.6. Faulty operations

Pumping/compression of gas or gaseous mixtures having a temperature greater than the systems temperature classification.

Pumping/compression of gas or gaseous mixtures having a spontaneous combustion temperature less than the systems temperature classification (see section 1.2.4.2).

Pumping/compression of hydrocarbon oxides.

Pumping/compression of pyrophoric gas.

Usage with oxygen-rich atmospheres.

Using the positive displacement blower under ambient conditions other than those specified in section 2.1.

WARNING

The category 2 or 3 ATEX-compliant blowers are based on the safety construction principle for the safe pumping/compressing of flammable materials. Under normal operating conditions, as defined in this manual, they can safely pump/compress

flammable materials as long as particles (of more than 25 ) cannot penetrate, which would cause a risk of potential ignition.

WARNING

It is strictly forbidden to use the category 2 or 3 ATEX-compliant blowers under the following conditions

05/05/2008 9 Issue A

1.3. Applications All of the SN blowers are suitable for pressure or vacuum operation.

Suitable for pumping/compressing surrounding air, such as gas and gaseous mixtures, according to this notice

The blowers are suitable for pumping/compressing ambient air, and non-flammable gases, gas mixtures and dusts. The blowers are not suitable for pumping/compressing flammable or pyrophoric gases, gas mixtures and dusts.

The materials of construction of the blowers are specified in Section 2.7. Before you use the blower, you must ensure that these materials are compatible with the gases and vapours which you will pump/compress or which may exist in the external atmosphere.

You must ensure that your blower is suitable for your application.

If you have any doubts as to the suitability of the blower for your application, contact your supplier or Ingersoll Rand for advice

1.4. Principle of operation Refer to Figure 1. The SN blowers are positive displacement blowers, which incorporate two contra- rotating three-lobe rotors (8):

One of the rotors is driven by the drive shaft (5).

The other rotor is maintained in the correct phase relation by timing gears.

During operation, the inlet gas stream to be pumped/compressed enters the blower at the inlet (2).

As the two contra-rotating rotors turn, the inlet gas is trapped in the chambers which form between the rotors and the blower-body, and is eventually forced out of the blower at the outlet (3).

The timing gears and the bearings on the rotors and drive shaft are lubricated by oil in the drive end cover (4) and non-drive end cover (12)

3. Installation

3.1. Conditions for installing the ATEX-compliant blowers

The category 2 or 3 ATEX-compliant positive displacement blowers must be installed according to the instructions set forth in this manual in order to ensure the validity of the ATEX category 2 or 3 certification.

The following conditions must be met:

The design of your system must meet the conditions specified in section 3.3

Your system must be designed in such a way as to protect the positive displacement blower against penetration by particles of more than 25 (9.84 x 10 inch). If this is not the case, use the appropriate filters.

3.2. Installation safety

A suitably trained and supervised technician must install the blower.

Ensure that debris and dust does not get into the blower or the system pipelines when you install the blower.

Check that all of the required components and tools are available and of the correct type before you start to install the blower.

Use suitable new gaskets/seals to connect the blower into your system. Do not reuse old gaskets/seals.

If you will fit the blower into an existing system, disconnect the power from the drive system before you start installation, so that the drive system cannot be operated accidentally.

WARNING

The category 2 or 3 ATEX-compliant positive displacement blowers must be installed according to the conditions stipulated in this section.

05/05/2008 36 Issue A

ATTENTION

Make sure that the maximum differential pressure in the positive displacement blower unit, specified in section 2.2, cannot be exceeded. If it does exceed, the drive is triggered and the

positive displacement blower stops.

3.3. System design and safety

3.3.1. General instructions

Your system must be correctly designed to ensure proper functioning of the positive displacement blower.

Your system must be designed in such a way that you can see the oil gauges and access the oil filling and draining stoppers when the positive displacement blower is in its final location.

We also recommend that you build into your system an emergency stopping device which, when activated, must be manually reset before the positive displacement blower can be started up again.

Note: Pressure/vacuum relief valves and acoustic enclosures are available from Ingersoll Rand: contact your supplier or Ingersoll Rand for advice.

You must incorporate a pressure relief valve in the outlet pipeline (for pressure operation) and/or incorporate a vacuum relief valve in the inlet pipeline (for vacuum operation), to ensure that the design capability of the blower cannot be exceeded during operation. The relief valve(s) must be suitably rated/sized for the performance of the blower.

You must ensure that people are protected from accidental contact with the blower or the outlet pipelines. During blower operation, the temperature of the blower and the outlet pipelines will be high (up to 70 o C, 158 o F). If necessary, fit suitable guards.

Your design must ensure that people are protected from accidental contact with the discharged (outlet) gas stream during blower operation. This gas stream may be at high pressure and can be hot (see above) and cause burn injury.

Your design must ensure that materials or substances which are flammable at temperatures of 70 o C (158 o F) or above are not close to, or in contact with, the hot blower or outlet pipelines.

The blower is noisy during operation (see Section 2.5). You must either install the blower in an acoustic enclosure, or ensure that people wear suitable protective equipment (such as ear defenders) when they are close to the operating blower.

Your system design must ensure that the blower cannot be operated with the inlet or outlet pipelines blocked or obstructed.

Also take note of the following:

You must design suitable pipelines to fit the blower inlet/outlet connections. Refer to Figures 3 and 4 for the dimensions of the blower inlet and outlet connections.

05/05/2008 37 Issue A

Your system design must ensure that the blower cannot be operated with the incorrect direction of rotation (see Section 3.7).

Your system must incorporate a suitable mounting platform (see Section 3.4).

Your system design must ensure that, when the blower is in its final operating location, you can see the oil-level sight-glasses and can access the oil filler and drain plugs.

There must be at least 150 mm (6 inches) of free space around the blower (even when the blower is in an acoustic enclosure), for adequate cooling-air circulation.

We recommend that your system incorporates an emergency stop facility which, once activated, must be manually reset before the blower can be operated again.

We recommend that you incorporate a filter in the inlet pipeline, to prevent the entry of particles or debris into the blower.

We recommend that you incorporate non-return valves (check valves), to prevent reverse rotation of the blower when it is switched off.

We recommend that you incorporate silencers, to attenuate the pulsations in the inlet/outlet gas streams.

Note: Filters, non-return (check) valves and silencers are available from Ingersoll Rand: contact your supplier or Ingersoll Rand for advice

Your system must be designed in such a way that the positive displacement blower can not function when the suction or discharge pipelines are obstructed.

Gasses that penetrate the positive displacement blower cannot contain solid particles of more than 25 (9.84 x 10 -5 inch). Install the appropriate filters to prevent any penetration of solid particles into the positive displacement blower.

The temperature of gasses exiting the positive displacement blower must not exceed the temperature classification (see section 1.2.4.2). Make sure that the positive displacement blower cannot rotate in the wrong direction (see section 3.9).

3.4. Unpack and inspect

1. Use a suitable fork-lift truck or pallet truck to move the blower, on its pallet, close to where you will install it.

2. Remove all packing materials and protective covers and check the blower. If the blower is damaged, notify your supplier and the carrier in writing within three days; state the Item Number of the blower together with your order number and your supplier's invoice number. Retain all packing materials for inspection. Do not use the blower if it is damaged.

3. Check that you have received the items listed in Table 32. If any item is missing, notify your supplier in writing within three days

4. Look at the blower rating and identification plate (Figure 1) and check that the blower is suitable for use in

5. MAINTENANCE

5.1. Safety information

A suitably trained and supervised technician must maintain the blower. Obey your local and national safety requirements.

Ensure that the maintenance technician is familiar with the safety procedures which relate to the gases pumped/compressed by the system in which the blower is installed.

Allow the blower to cool to a safe temperature before you start maintenance work.

Isolate the blower from the drive system so that it cannot be operated accidentally.

Recheck the blower rotation direction (see Section 3.7) if the drive and transmission system has been disconnected and then reconnected.

Take care to protect the inlet/outlet port sealing faces from damage.

Do not reuse seals/gaskets if they are damaged.

Check the leak tightness of the system connections after maintenance work is complete if you have connected or disconnected the blower inlet or outlet joints. The leak tightness of the system connections must be in accordance with the requirements of your applications.

5.2. Maintenance plan

The plan in Table 35 details the maintenance operations required to maintain the blower in normal operation. Instructions for each operation are given in the section shown.

Note that:

If you use a mineral oil in the blower: you must change the oil every 2000 hours of operation.

If you use a synthetic oil in the blower and you operate the blower with a discharge (outlet) temperature above 120 o C (248 o F), you must change the oil every 6 months.

If you use a synthetic oil in the blower and you operate the blower with a discharge (outlet) temperature below 120 o C (248 o F), you must change the oil every year.

Note: for category 2 or 3 ATEX-compliant positive displacement blowers, you must maintain the positive displacement blower according to the schedule set forth in table 35 (or even more frequently) in order to ensure the ATEX compliance.

When you maintain the blower, use Ingersoll Rand spares: refer to Section 7.3
