TANGRA SR ventilation extraction valves are designed for exhaust air, most often from sanitary and storage rooms. They are mounted on the ceiling or ventilation ducts and the air flow can be extremely easily adjusted through the screw connection of the central disk. The air flow rate of a single extraction valve can be from 100m3/h up to 500m3/h (27l/s – 139l/s).
- They are made of galvanized or stainless steel (mirror or matte).
- The air flow adjustment is done by turning the central disk, which is attached to the base by a central bolt.
- They are mounted on a suspended ceiling by means of a mounting ring and a flexible air duct or directly on the air duct.
- The mounting ring is part of the extraction valve.
