in search of a solution for efficient ventilation I came across the compact pressure flap of Compair. The advantages that convinced me were unlike other products on the market: - Reaction / springs of the flap already with simple ventilation level by smooth spring and thin sheets, - Damped stop the flaps so that the wind and fanless operation no rattling occurs, - Tight sealing of the valve in the operating condition, so that no air enters and the kitchen is cooled, - Simple installation without additional tools, as easily used in the existing pit, outside panel about it and you're done. The delivery took place in the short term and intact (despite oversized packaging), so that the seller may be recommended.
