TIGHT CONTROL DAMPERS, DEPTH 250
The product is intended for use wherever tight closure of air ducts is required, for mutual separation of spaces which must not be permanently connected by ventilation ducts. The temperature range for the use of tight control dampers is from -40 °C to +50 °C; when operating the dampers with an actuator, the temperature range is from -20 °C to + 50 °C.
For pipe dampers, the pressure difference p cannot be higher than 1000 Pa; in mixing chambers, etc., the pressure difference cannot be higher than 1500 Pa. The design of the damper allows it to be installed in holes in the masonry or in pipes.
