VSP - Plate Mounted Sickle Fans

Brand

Vent-Axia

Application

The latest generation of the Plate Mounted Sickle fans incorporate the very latest FE2 Owlett impeller offering improved performance over the previous ranges with up to 7dB(A) reduction in sound and up to 15% improvement in efficiency ensuring the best available fan performance in its class.

Specifications

Swept impeller with Aerofoil blades, winglets and serrated trailing edge for optimum performance
One shot die cast impeller, dynamically balanced for smoother operation
Operating temperature up to 70°C
External Rotor Motors on all models for compact efficient design
All models speed controllable
Guards fitted as standard on all models
Thermal Overload Protection for motor protection
Maintenance free sealed for life bearings

Composition

Impellers
The impellers incorporate the latest in sickle blade aerofoil technology to ensure minimum sound and maximum performance. Impellers up to 400mm diameter are moulded from a composite polymer, impellers above this size are Aluminium. The motors and impellers are factory matched, statically and dynamically balanced to ISO 1940 part 1, Quality Class G.6.3.
Motors
The external rotor motors are specifically designed and styled for this range of fan. Ball bearings are greased for life. Sizes 315 – 710 motors are protected to IP54 against dust and moisture, complying with BS EN 60529.
They have ribbed aluminium body castings for efficient cooling with Motor insulation to Class ‘F’ (from -40°C to + 70°C). Speed controlled sizes 450 to 710, 6 & 8 pole motors are only suitable for operating temperatures of up to 40°C.
Electrical
The Plate Mounted Sickle fan range is available for either single phase 220-240V 50 Hz capacitor start and run or three phase 380-415V 50Hz. Motors are fitted with Thermal Overload Protection which
should be wired into all controller circuits and into starter contactors to prevent motor damage due to overloading / overheating.
