They are suitable for daily room ventilation, for smoke and heat extraction systems (RWA) and as natural smoke and heat exhaust ventilator (SHEV). The drives are postioned parallel to the window and, depending on the colouring chosen, harmoniously match the window architecture. They have a special chain which can transfer both pulling and pushing forces. When closed the chain is concealed, it is rolled up in the drive housing.ECchain: simple automation options for ventilation (230 V)Cost eective and ecient starter modelUniversal use, especially in private housingIntegrated stroke adjustment to 200
