Horizontal Mounting Vane Air Motor

Use of Air Motors in Hazardous Atmospheres

Most of the Air Motors and some of the Gear Motors in this description meet the requirements of the CE directive 94/9EC (ATEX 100a). They may be used in zones 1 and 2 where explosive atmospheres of gas or dust are likely to occur. These are marked (Ex) II 2 G D c T4 in the description and on the product. This indicates the air motor is Group II, Category 2, Gas and Dust Atmospheres, and a maximum surface temperature of 275degree F / 135degree C. Check that the product driven by the air motor meets ATEX directives.

There are several points regarding the safety of air motors. Our air motors are not a source of electric sparks. However, it is possible that a article which is it part of the air motor (e.g., wrenches, hammers, etc) cold create a spark by sharply impacting a cast iron or aluminium case or the steel shaft of the air motor. [Note that electric motor enclosures for both class I and II hazardous locations ca be made of ‘’…iron, steel, copper, bronze, or aluminium….” (L 674, Electric Motors and Generators- Hazardous Locations,

Air Motor are designed to be operated by compressed air, the expansion of which create a cooling effect, As a result, the outside surface temperature and a maximum surface temperatures of 275degree F / 135degree C. Operation of the air motor with compressor air purges a flammable mixture from the inside of the air motor.
To prevent static electricity from being an ignition source electrically ground the metal air motor.
