Crossflow direct-drive blowers fit into long, narrow spaces and provide a steady flow of air across their entire length. Intake air is drawn in from the area around the blower wheel and pushed into an exhaust guide rather than moving through a fan scroll housing. This design reduces the chance of intake blockages which helps to ensure continuous operation in environments where cleaning or maintenance may be infrequent. They are commonly used in air curtains, electric fireplaces, and electronic cooling applications.
