Revision and repair

For some types of fans, e.g. for ATEX-fans after 3 years, a periodic revision is mandatory. 

At gastight ATEX-fans all interventions at the fan casing or at the impeller can affect the explosion/ignition protection of the fan. In many countries before re-startup after repair a check of the unit by an approved inspection body or an authorized person is mandatory (for Germany see BetrSichV §14.6).

Interventions not directly affecting the explosion/ignition protection of the fan (e.g. change of belts or change of motor of a belt driven fan) require at least a check by an adequate qualified person (Germany: BetrSichV §2).

We therefore strongly recommend these interventions at gastight ATEX-fans to be executed and checked by our manufacturer service. The manufacturers service ensures all mandatory checks (overspeed test, tightness test, clearance checks ...) and ensures documentation of it.

For some fan-types (natural gas) we offer exchange units for simple and quick revision with very short service interuption.

Also for other fans we recommend to perform a revision before end of bearing life expectancy to reduce the risk of an unexpected breakdown.

Our revision contains always a professional re-balancing of the impeller.

Revision by the manufacturer gives you the certainty, that only original spares have been used and installed properly.

If there should be a need of a repair, it can be carried out at your premises or in our factory.
