LTZ Series Forward-curved Blade Double-inlet Shaft-driven Centrifugal Fan
LTZ series forward-curved blade double-inlet shaft-driven centrifugal fan adopts a forward impeller directly connected with motor located outside through long shaft. The air enters from both sides at the same time. The structure is simple and reliable. At the same time, the resistance at the inlet of the fan is reduced, and the rated air volume and efficiency of the fan are increased .
Wheel Diameters
5.91~15.74inches (150mm~400mm)
Standard Performance Range
Airflow: min 178.5 CFM ～max 9,817.5 CFM ( 300 m3/h～16,500 m3/h, 10,594.40 ft³/h~58,2692.13 ft³/h)
Static pressure: 0.36~4.012 inches w.g. (90～1,000 pa)
Application Cases
This series is to handle large air flow at low speed as part of air conditioning system. This forward curved type of fans are widely used in make-up air units, which require low static pressure and this series can match. It can provide ventilation for all types of commercial and home buildings, plants, do airflow control of air supply and exhaust in working process as air handler, supply fresh air and help keeping at comfortable environment in livestock farm.
