The VCR / VCR-T range of centrifugal low pressure fans are specifically designed to be installed within rectangular ducted ventilation systems or where the space for installation is limited. The range comprises of eight nominal model sizes, covering 23 models in total. The range is available with single 230V 50Hz, or three phase 230/400V 50z motors in 4, 6 and 8 pole speeds.

Air volume performance ranges from 1,090 up to 10,235 m3/hr.

All models are suitable for mounting in any orientation and operation within ambient air temperatures between -40º C up to +70º C.

The Direct-Air ILT/ILB range are suitable for many general ventilation applications where the fan is required to be installed within a rectangular ducted ventilation system or where the space for installation is limited.

Due to the configuration of the design, the dimension of the fan section would be no greater than that of the proposed nominal ducting.

Typical installations would include:
  • Commercial offices air extract / supply
  • Car park supply air
  • Restaurants
  • Installations where the mounting space is limited or confined

The fan casings are manufactured from heavy gauge galvanised sheet steel. All models incorporate an inspection cover that can be removed to access the motor / impeller assembly without having to remove the complete fan casing from the ducting.

Motor / Impeller

All models incorporate direct-drive low pressure forward curved centrifugal impellers.

The impeller is factory matched to the motor and the complete assembly is dynamically balanced to ISO 1940 standards.


All models incorporate asynchronous induction motors with squirrel cage rotor in die cast aluminium. Manufactured in accordance with IEC 34-1 standard.

The following specifications apply.
  • Single Phase 230V 50Hz.
  • Three Phase 230/400V 50Hz.
  • IP55 protection.
  • Class F insulation.
  • Thermal Overload Protection.
  • Sealed For Life, ball bearing assemblies.
  • Remote mounting wiring outlet box. (800mm lead length).
  • All models, both single and three phase, are suitable for speed control regulation using auto-transformer type RMB-RMT products.
