ATEX Roof Fans in Application

ATEX roof fans are extraction fans to be installed on roofs of  buildings, whether commercial or industrial. This type of fan can be adapted to any type of roof thanks to the adaptable bases on site that allow them to tilt in different positions. The objective of roof extractor fans is to keep buildings in healthy condition by extracting stale air, smoke and keeping the temperature and humidity levels at the proper levels. In this way, a healthy indoor environment is achieved that benefits both the people who work or live in it as well as the machinery and the building itself.
Suitable Applications

• Smoke extraction.
• Smoke emergency exhaust with motor outside the hazardous area.
• Air renewal in buildings and industries.

We also have roof fans for smoke evacuation certified F400.
