RFC and RFE centrifugal fans are one-sided intake fans driven by flange electric motors. They are designed for air exchange in civil construction, industrial premises and agriculture. (e.g. granaries). RFC fans are low-pressure fans (with forward-curved impeller blades), and RFE fans are medium-pressure (backward-curved impeller blades). Centrifugal fans are available in several types, versions and sizes with impeller diameters ranging from 200 mm to 630 mm.

Essential characteristics:

Examples of product labelling

Transported air temperature

-30°C to + 85°C or -30°C to + 40°C for Ex fans

Design

  • for use in ordinary environments (RFC and RFE)
  • for use in potentially explosive atmospheres – Ex1 (RFC)

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

  • RFC– 200, 250, 280, 315, 355, 400, 500, 630
  • RFE– 200, 250, 280, 315, 355, 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)
  • AKV1 – stainless steel sheet (ČSN 17240, DIN 1.4301) – for the pharmaceutical and food industry
  • AKV2 – stainless steel sheet (ČSN 17348, DIN 1.4571) – for the chemical industry17348, DIN 1.4571) – pro chemický průmysl

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

Also available as a fanfor horizontal positioning(H, HL)

Fan positions

Rubber vibration isolators are supplied as standard with the fans (except for the H version).

RFC and RFE fans shall not be used to transport air containing aggressive substances, abrasive additives and fibrous or sticky particles.

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.

All RFC and RFE fans comply with ECODESIGN ErP 2015 (Commission Regulation (EU) No. 327/2011)

H and HL fans

For special applications, RFC and RFE fans in the H or HL versions are available. They have a reinforced spiral casing structure and allow installation in a position with a vertical rotation axis of the impeller. The H version is designed for applications where the total weight of the fan is applied to the intake flange, and the HL version is also designed for applications where the fan is positioned horizontally, but the total weight of the fan is transferred to the rubber spring feet. The H and HL fans are mainly used for installing on the roofs of spray booths and various workstations.

Accessories

Rubber vibration isolators are supplied as standard with the fans (except for the H version). A wide range of accessories can be added to the delivery, according to the customer’s wishes.

Base plate

for mounting the fan on a flat horizontal structure

Motor cover

with a horizontal rotation axis as weather protection

Cover grille

for the intake opening (if not connected to a duct)

Flexible insert

between fan discharge and a duct, between fan intake and a duct

Adapter

for the intake opening, for the discharge opening

Motor canopy

with a vertical rotationaxis
