High-capacity ventilator with smoke and heat extraction function!

The Series RIF ventilators, including the sound attenuating models A1 to A3 and RIF-SD, can also be equipped with a smoke and heat extraction unit in accordance with the relevant DIN standard. Based on extensive tests, GAL received its first certificate of conformity for the gravity roof ventilators with smoke and heat extraction functions. These tests are according to the DIN 18232 standard, Part 3. They comprise an operational safety test that is performed by activating the control dampers 10,000 times, and a fire test in which the ventilator is exposed to a temperature of 300°C in a fire chamber.

Series RIF gravity roof ventilators with integrated smoke and heat extraction functions attain a coefficient of discharge Cv0 of 0.65 to 0.75 depending on the model.
