AREX
Industrial fans

The AREX range of fans comprises centrifugal, roof-top and axial flow fans designed for handling air or gases that are corrosive or dust-laden. The fans are made of materials such as PVC, PP, PE, PVDF and GRP. The material used for a given application depends on factors such as resistance to chemicals, heat resistance and strength. A full range of accessories is available for all fans, which enables us to offer a comprehensive fan system.

AREX fans are available as standard

- with connection from 125 mm up to and including 1120 mm diameter

- with three types of fan impellers:
  • T impeller with straight, radial blades
  • B impeller with backward-curved blades
  • P impeller with straight, backward-sloping blades
- in low-pressure, medium-pressure and high-pressure versions.

- for flow rates up to 100.000 m3/h and pressure rises up to 6.000 Pa.
 


Plastic fan type LCPA is made of various plastic materials: PP, PPS, PVC, PPS-el, PVDF and GRP - glass fibre reinforced polyester or vinylester - with straight radial blades.
LCPA ist made in nine sizes, direct or belt driven.
     
Plastic fan type LCPS-071-10-6-1 ready for delivery. Dimensioned for flow rates of 20.000 m/h and total pressure up to 650 PA, has a motor of 11 KW and intended for control with static frequency changer. The casing of the fan is of rigid PVC and the wheel of GRP. Splinter protecting cover of EPDM.
  



An important part of the Arex range of plastic ventilators is manufactured of GRP, glass-fibre reinforced polyester or vinylester. GRP fans are used especially in the following corrosive invironments:
- at high temperatures up to 115°C
- at high speed and high pressure
- on special demand for a shockproof construction
 
Plastic fan type LCPB 100-11-6-1-1 made of GRP, installed in a pickling plant at a drawing mill.
Flow rate 35.000 m/h at total pressure 1.500 PA. Motor 37 KW and 73 A. Installed together with a droplet eliminator.

AREX roof-top fans
The fan casing is made of GRP (polyester) and gives an optimal impact protection and enables a long lifetime against aggressive gases. The vertical ventilation outlet with high air speed reduces the risk that evacuated gases will fall on the roof.
