Exhaust fans, flue gas extractors
Exhaust fans can be used to strengthen the chimney draft in a boiler. They are usually mounted on the flue pipe and support the operation of the blower connected as a supply fan. The fan itself cannot be used as a draft in places where it is not natural. The fan is only meant to assist the extraction and improve its effects. The exhaust fan is available as a standalone device as well as together with a housing adapted for operation, which has appropriately sized connections. Exhaust fans have two identical impellers, which depending on the application, come with motors of equal power and various finishing configurations. The exhaust fan for flue gases is used in solid fuel boilers to improve the chimney draft. This is especially useful during lighting the boiler or adding fuel because it prevents smoke from escaping into the boiler room. Mounted on the boiler's flue pipe, the exhaust fan does not limit the natural flue gas draft but only supports it when the fan is turned on.
