They are low-pressure one-sided intake centrifugal fans driven by flange electric motors using belt drives. They are designed for air exchange in civil construction and industrial premises.

Essential characteristics:

Examples of product labelling

Transported air temperature

-30°C to + 85°C, 30°C to + 85°C for Ex fans

Executed

  • for use in ordinary environments
  • for use in potentially explosive atmospheres – Ex1

Sizes (depending on the outer diameter of the impeller in mm)

  • RFC-PR – 250, 315 and 400

Control

The fans can be controlled either by the ON/OFF switch, and thus the fan can be used at maximum power, or the fans can be controlled by a frequency inverter, and thus the fan output can be regulated continuously. Frequency inverters are supplied preprogramed for a specific motor based on the most optimal fan noise parameters.

Ambient temperature

-30°C to + 40°C or -20°C to + 40°C for Ex fans

Material

  • Z – galvanized sheet metal
  • E – galvanized sheet metal + enamel (powder)

Position

  • P – right (top right discharge when viewed from the intake side)
  • L – left (top left discharge when viewed from the intake side)

The discharge can be rotated at 45° angles during installation

Fan positions

Rubber vibration isolators are supplied as standard with the fans.

The fans can be equipped with a wide range of accessories: base plate, motor cover, motor canopy, flexible inserts, intake grille and various types of adapters and attachments.

RFC-PR fans must not be used to transport air that contains aggressive substances, abrasive additives and fibrous or sticky parts.

RFC-PR fans comply with ECODESIGN ErP 2015 (Commission Regulation (EU) No. 327/2011)
