SWSI Backward Centrifugal Fan Impeller

As experienced manufacturer and supplier, CHOSEN provides Backward centrifugal wheel / impeller with size of 250mm ~ 1400mm. Strong air flow, middle and high pressure. Dynasmic balance test.

Application

· Integrated fans.
· roof ventilators.
· ventilation and air-conditioning systems (HVAC/AHU).
· industrial applications.

Advantages

· Various material for option :
Galvanized steel, Stainless Steel #304/#316/#316L, Aluminum Alloy.
· Each impeller will do by twice dynamic balancing tests, one is after the completion of welding and the other is after coating. The balance grade of the impeller can be G2.5. It greatly improves the stability of the impeller operation, and reduces the vibration and noise. Meanwhile each impeller also so Radial Running, Axial Vibration.
· Each impeller Each impeller is made of moulding, with continuous welding in the settle machine, the components positioning is accurate, the strength is high , make sure of the precision of the processing and the product performance is more reliable
