Bifurcated Fans
Properties:
- Designed with a split airway and the motor is protected from the handled air by having its own compartment.
- Motor is isolated from the main air stream by a tunnel which extends to the side of the main fan casing.
- Suitable for some mild chemicals that will not corrode the galvanished casing or the seal of the motor shaft through the case.
- When fitted with an anti- spark track can also be use to handle hazardous gases.
The casings are manufactured from mild steel with hot dipped galvanized finishing after manufactured as an anti-corrossive measure and for longer life as a standard.
The casing of the 315 to 500mm diameter sizes have an enlarged bore located around the motor to permit adequate cross sectional area for air to flow round the motor tunnel.
The 560 to 1250mm diameter sizes have casings of constant diameter.
The axial impellers are balanced on quality level G 6.3 according to DIN ISO 1940.
The hubs of chilled casting aluminium are made in two parts and have removal drilling for easy dismounting of the impellers.
The profile blades are made of aluminium die cast with adjustable blades.
TEFC , three phase IEC motors of type B5 with protection class IP 55, insulation class F are used.
Pole changeable, voltage controllable, inverter control or high temperature motor are available upon request.
Motor used comply with with electrical standard BS5000 and mechanical standard BS4999.
Single phase 220/240V are available for smaller fan diameter size only.
60Hz motor are also available upon request.
