Twin Fans for Roof Installation - Extra Quiet TFRA

The Helios Twin roof fans have been specifically designed for continuous ventilation in commercial buildings with internal toilets or toilets that have no opening. For noise sensitive applications the acoustically lined units (TFDA) provide the ideal solution. All units in the range have two direct drive centrifugal fans with an individual back draught shutter & separate electrical connections to the terminal, ensuring 100% standby. Roof mounted models offer a weather protected unit with outlet louvres and a rear mounted inlet spigot for circular ducting.
