Belt driven cabinet fans CVTT Series

CVTT

Range of forward curved belt drive cabinet fans manufactured from galvanised steel sheet, internally lined with melamine acoustic insulation (M1). All models incorporate a double inlet low pressurecentrifugal fan mounted on anti-vibration mounts and flexible coupling at the discharge. Supplied as standard in horizontal discharge (code H) configuration with motor, pulley and belt assembly on the right hand side of the unit when viewed from the discharge end.

Motors
All motors are IP55, class F insulation.
Electrical supply:
– Three phase 220-240/380-415-50/60* Hz up to 3 kW.
(*Check Easyvent for 60Hz available models)
– Three phase 380-415V-50Hz, for higher power motors and two speed motors.
(See characteristics chart)
– Single phase 230V-50Hz, with a maximum of 1,5 kW (CVTB version).
All motor up to 2,2 kW are mounted onto the fan casing scroll.
All motor above 3 kW are mounted onto an adjoining support frame.

Attributes

Low noise level
Acoustic insulation of 7 mm thickness flame retardant (M1) melamine foam reducing the noise level significantly.
Flexible coupling at the discharge
To reduce vibration and noise transmissions to the installation.
Robustness
Quality finishing, with aluminium corners providing a high robustness.
Versatile outlet discharge
Vertical discharge models available under request.
Anti-vibration mounts
The fan is mounted on base frame with silent-blocks to reduce vibration and noise transmissions to the installation.
