Delivering The Power of Ventilation
AHE fully adjustable pitch fans are available in a full range of metric sizes from 250mm diameter up to 2000mm diameter. The wide range of diameters, blade configurations, pitch angles and motors speeds, allow accurate selection of the fan to match the specific duty.
Pitch angle adjustment can be readily carried out on site allowing the fan performance to be modified to the final system resistance.
The standard range of axial fans cover most applications, specific designed casings and mountings are available. Casings are manufactured from mild steel, galvanized sheet, hot dipped galvanized or epoxy painted after manufacturing.
Adjustable Pitch Axial Fans
Casings shall be of mild steel, galvanized sheet, hot dipped galvanized or epoxy painted after manufacture. The long cased type enclosed completely both impeller and motor. This arrangement a weatherproof welded junction box is standard. The short casing type encloses the impeller only and electrical connection are made directly to the motor terminal box. Both casings incorporate foot mount motor as standard. All casings are hot dipped galvanized or epoxy painted. Alternative paint finishes are available upon request.
The AHE adjustable pitch range of impellers are manufactured from high pressure die cast aluminums from WingFan of Germany. The pitch angle range is from 20 to 50 degrees. To obtain optimum performance the impellers are fitted with different solidity and this allows selection at pick efficient. Other blade’s material eg. Glassfibre or Carbonfibre(anti-static) reinforced polyamide are also available. Custom made solution of more than 50 configuration is in the range of offer.
Standard motors are of the TEFC type to class F insulation, with class B temperature rise and the enclosure are to IP55 as standard. Other motor type eg. Flameproof or 2 speed are available upon request. On Smoke Extract Application, special motor to class H insulation and made to operate for 2 hours up to 250°C can be manufactured.
