Dayton plenum fans are suitable for discharging clean air (at low to moderate pressures) in air handling and pressurised plenum applications. These units consist of centrifugal fan wheels that produce less turbulent airflow for increased performance. They have galvanised steel frames for durability, strength and are capable of withstanding temperatures up to 150 degrees F. They also have ball bearings for a smoother and continuous operation. Choose from a wide range of these plenum fans, available in fan motor speeds ranging between 1725 and 3450 rpm.
