FANS / CATEGORIES / TYPES
PRODUCT TRANSPORT FANS (material handling fans).
Aviation fan
Centrifugal fans of this type are located before the filter and transport together with the air and the product, such as sawdust, sawdust, broken corn from the mill, broken plastic flakes, fibers, paper scraps, light dusts, etc. Their propeller has backward inclined blades, so it is self-cleaning. The motor can be connected directly and then gives 2880 rpm. The fan JK25D – 4.0kW with suction inlet Φ250mm has a delivery of 4’000m3/h at a vacuum of 1800Pa. Also the motor can be connected in parallel with pulleys. The fan JK40K – 15.0kW at 2600 rpm with suction inlet Φ400mm has a delivery of 9’000m3/h at a vacuum of 3000Pa
LOW PRESSURE clean air fans.
Centrifugal fans of this type are located after the filter and carry clean air. Their propeller has backward inclined blades, so it is self-cleaning. It is designed to give maximum air flow with the least possible energy consumption. The motor can be connected directly and then gives 2900 rpm. The fan JK40MTD – 11.0kW with suction inlet Φ400mm has a delivery of 7’000m3/h at a vacuum of 3300Pa. Also the motor can be connected in parallel with pulleys. The fan JK50MT – 22.0kW at 2150 rpm with suction inlet Φ500mm has a delivery of 10’000m3/h at a vacuum of 3850Pa.
