A combustion blower is a motor that is used in furnaces. It is generally used to exhaust duct gases and pre-purge the heat exchangers.
Combustion blowers are devices that use high-pressure air in the high and mid-efficiency ducts of the furnaces. They are used to heat, ventilate, and air condition the vents of the furnace systems.
It is used to make the flow of the air in the furnaces more stable and constant so that the heating process is continuous and efficient. Based on speeds the blowers are positive displacement and centrifugal blowers.
Therefore, the blower is used to exhaust the gases of the vents.
