Features & Benefits
Backward Bladed Fans These simple yet highly effective centrifugal fans generally offer highly efficient and cost effective solutions when operated in clean air or with light dust loads. Available with both left and right hand rotation discharge orientation can be aligned in accordance with all Eurovent and iSO specifications and to any other angle necessitated by special order.
Routinely available impeller types include:
- BFN – Flat backward inclined
- BLZ – Backward curved with three types of blade geometry coded BLX, BLV & BLT
- BAW – Backward curved aerofoil Standard units are equipped with foot mounted T.E.F.C. electric motors and finished with a zinc phosphate coating but other drive trains and epoxy paint, hot-dipped-galvanized and stainless steel finishes can be specified where required.
Forward Curved Multi-Vane Fans
These units feature a large number of shallow blades curved forward towards the direction of rotation with impellor widths greater in diameter than in a backward inclined model. Producing high flow rates at low pressures with a relatively low tip speed results in high efficiencies coupled with very low noise in operation. Available in a range of sizes offering flow rates of up to 60M^3/Sec at 1.0kPa these centrifugal fans can be specified with both right and left hand rotation and standard Eurovent and ISO discharge angles. Other angles are also available by special request.
High Pressure Centrifugal Fans
Designed to deliver high impeller tip speeds and pressure development at relatively low flow rates these units are available in fully shrouded, radial or near radial blade configurations suitable for blower or suction applications. Flow rates of up to 2.5M^3/sec are available from our standard product range. Available in either right or left hand rotation modes discharge orientation as standard can be to any Eurovent or ISO angle with other angles to special order. Multiple drive arrangements are offered as standard together with full flexibility on choice of motor windings, voltages and frequency. ATEX (11 2/3/G/D T1-T6) specification units are available for deployment in hazardous areas.
