Axial

Standard Arrangements

Format Configuration Features
Long Cased Fans lca-section-final600 Motor sits directly in the air stream.
Sizes from 250mm up to 2400mm.
Short Cased Fans sca-Model Motor sits directly in the air stream.
Sizes from 250mm up to 2400mm.
Belt Driven Axial Fans bda-section-Model Motor sits outside of the casing. The impellor is driven by vee belt drive through a shaft and bearings, both of which are located inside a tunnel isolating them from the airstream.
Sizes from 700mm up to 1500mm
Bifurcated HD Fans hd-section-Model Motor sits within a tunnel isolating it from temperature and contaminants.
Sizes from 250mm up to 1500mm
Bifurcated LD Fans ld-section-Model Motor sits within a tunnel isolating it from temperature and contaminants. This fan is cheaper but less efficient than the Bifurcated HD fan .
Sizes from 250mm up to 1500mm.

Special Arrangements

Format Configuration Features
Direct Driven Axial Plug Fan axial-plug-fan-dd-Model Impellor type stainless fabricated plate blade. Impellor track with inlet and outlet bellmouth / made from 3mm stainless steel.
Belt Driven Axial Plug axial-plug-fan-bd-Model Impellor type stainless fabricated reversible aerofoil section blade. Impellor track with inlet and outlet bellmouth / made from 6mm stainless steel.
Short Cased Axial With Bellmouth sca-bellmouth Cost reduction over standard casing with additional bellmouth, that has to be bolted on. This can also be applied to long cased fans.

Impellors

There is a wide choice of impellors, with varying hub ratios, blade numbers and blade angles. This variety allows us to select the best operating efficiency for a given duty.

Impellor blades can be made of the following materials:-

  • Aluminium – Maximum Temperature is 240ºC.
  • Glass Reinforced Polypropylene (PPG) – Maximum Temperature is 90ºC.
  • Glass Reinforced Polyamide (PAG) – Maximum Temperature is 110ºC.
  • Glass Reinforced Polyamide, Industrial quality (PAGI) – Maximum Temperature is 110ºC.
  • Anti Static Glass Reinforced Polyamide (PAGAS) – Maximum Temperature is 110ºC.
  • Normal & High tensile Carbon Steel – Maximum Temperature is 450ºC.
  • 304 / 316 / 321 Stainless Steel – Maximum Temperature is up to 750ºC.
