Standard Arrangements
| Format | Configuration | Features |
|---|---|---|
| Long Cased Fans |  |
Motor sits directly in the air stream. Sizes from 250mm up to 2400mm. |
| Short Cased Fans |  |
Motor sits directly in the air stream. Sizes from 250mm up to 2400mm. |
| Belt Driven Axial Fans |  |
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 |  |
Motor sits within a tunnel isolating it from temperature and contaminants. Sizes from 250mm up to 1500mm |
| Bifurcated LD Fans |  |
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 |  |
Impellor type stainless fabricated plate blade. Impellor track with inlet and outlet bellmouth / made from 3mm stainless steel. |
| Belt Driven Axial Plug |  |
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 |  |
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.
