Selection & Compliance

What actually makes a fan explosion proof, which fan type suits which duty, how to size airflow and pressure properly, and the installation details that decide long-term compliance.

What IEC 60079-17 requires: the three inspection grades, how often to inspect, a lighting checklist and the faults behind most Ex non-conformities.

LED and fluorescent explosion-proof luminaires compared on life, maintenance cost and temperature class, plus a 12-point retrofit checklist.

Marking first, light level second. How to size luminaires by lux target instead of old wattage, match the beam to the mounting height, and specify for corrosion.

A ten-minute routine that prevents most disputes: match the model, read the conditions of use, and confirm the certificate in the public register.

ATEX, IECEx and the North American Class/Division system describe the same physics but are not interchangeable paperwork. The installation country decides.
