The Kair air valve is ideal for moderate ventilation in all rooms that have no special fire protection requires.
The disc valve can be used both for supply and exhaust air.
It is made of stainless steel with a brushed finished, making it weatherproof and suitable for use in outdoor areas.
The wide edge evens out potential bumps on the wall or diameters of the opening.
The corresponding mounting ring ensures a stable hold in thin materials such as ceiling panels or metal ducts, at the same time the ring also serves as a connection piece to flexible tubes.

Can you tell me the hole size and tolerance required in the ceiling to fit this valve? Thank you.
Space requirement is 172mm * 172mm * 62mm.
Does this vent open and close on a screw thread, and if so how much is the movement from open to close. I need to calculate the free air movement. If this does not open and shut, do you have one that does?
Hi does this come with a ceiling mount kit, we will have a flexible 125mm duct connecting to this, not a rigid duct for it to push in to. Can you please advise if another part is required. Thanks Gareth
