FläktGroup valves are suitable for houses, offices etc. They are made of sheet steel and powder coated in white (RAL 9003) and CleanVent coating as standard. The body is equipped with cellular plastic gasket to form an airtight seal. Adjustment of the air flow is simple, the inner cone being rotated to the required setting and locked in the position with a single nut. The valve is installed by fitting it into the mounting ring so that both ends of the truss support the tracks of the ring firmly. For complete design, instructions for installation, adjustment and maintenance details are available at www.flaktgroup.com.
