Aluminum ventilation damper DA / GK / GB / DSQ SERIES

galvanized steel

Dampers are made in diameter range from 80 mm to 630 mm of galvanized, aluminium and acid-resistant sheet. Regulating damper DAR/DARL passes about 30% of air with a possibility of full opening of a duct. Shut off damper DAS/DASL stops about 95% of air during full closing stage. Airtight damper DAT/DATL enables full closing of a duct and in connection with a servomotor with a return spring it acts as a closing flap. Sliding dampers GK/GKL enables cleaning of ventilation installations. Iris type dampers GBL enable a stepless adjustment of air jet - they are equipped with a connector for a measuring device. By-pass dampers DATVTL or DATATL are used for intaking air into a system from two sources such as a wall mounted air intake grille and an air exchanger. Dampers are used to ventilation systems.
