These ventilators may be used directly for gas, welding or steam aspiration, and if a spark detector and/or a particle collector is installed, it may also be used for polishing aspiration.

The ventilators are either installed on the roof or on a wall by means of brackets.

Fields of application:

The Prima-vent ventilator types A1000 - A7000 are especially designed for gas, welding fume and particle aspiration.

The ventilator casing is made of galvanised sheets in order to avoid corrosion. The ventilator wing is made of moulded aluminium, which carries the advantage that the ventilator becomes spark-free.

Air volume
The ventilator range type A covers from 1000 m3/h – 0.55 kwh to 7000 m3/h – 7.50 kwh.
