The ASK model does not only look good, it also enables to direct the air flow thanks to the moveable front. ASK valves can be installed both as air supply and exhaust units in mechanical and natural ventilation systems. Powder coat used to cover the components not only makes them more aesthetic, but also protects against corrosion or scratches. Each device is delivered with a mounting frame, that is made of galvanised sheet metal.
