It is important to use ATEX approved pneumatic motors in hazardous areas where explosive dust or gas may be present. Even pneumatic motors can generate enough heat to become ignition sources in certain environments.
The ATEX approval is a European standard for equipment that is used in explosive atmospheres. An approved motor will have a code on it that shows what environment it is suited to (eg mining or industrial), what form of hazardous materials it is safe for (eg gas or dust) as well as the rated surface temperature of the motor. An ATEX approved pneumatic motor has been tested and will be given a temperature class, as well documented maintenance intervals and procedures to ensure that it remains safe in your environment.
Using a non ATEX approved motor should only be done if a satisfactory risk assessment has been done, including long term temperature and bearing testing has been completed. Pneumatic motors are the logical choice for use in hot, dusty, wet or explosive environments, or applications where size and weight are important – especially if high start torque is required.
