The Biasi air pressure switch is a safety mechanism that ensures the fan is fully operational. It ensures that if the fan fails within the boiler, there will not be a build up of noxious fumes with no means of venting them. The Printed Circuit Board closely monitors the air pressure switch to make sure it is in full working order before the unit is fired up, preventing the appliance from starting without one of its key safety devices.
Fits multiple Biasi appliances
