Available as direct driven or belt driven units these fans are ideally suited for generating large quantities of air at low pressures and with minimal noise, an often overlooked factor when choosing the correct fan for the job.
Direct Driven Axial Fans
Offering similar advantages to the belt driven units but available in two configurations, one with the outer casing covering the complete impeller and motor, (long cased variant) and the short cased type which is configured to permit a portion of the drive motor to project beyond the casing. Individual units can provide gas flow rates of up to 90M^3/sec.
Staging of this type of axial fan in series operating with contra-rotating impellers can provide for flow rates of up to three times the pressure of a single stage fan of equal diameter and running speed.
As with their counterparts, direct driven units are offered with a choice of impeller pitch and materials of construction offering great flexibility for use in numerous environments.
Belt Driven Axial Fans
These units of generally specified when it is important to keep the motor away from the airstream generated due either to temperature or the nature of the gases being processed. An additional advantage is that by correctly specifying the positioning of the motor ease of maintenance is assured.
Capable of gas transfer rates of up to 80M^3/sec and with impeller sizes from 315mm -1400mm diameter these units are supplied as standard with variable or fixed pitch GRP or aluminium blades installed in a die-cast aluminium hub. A wide choice of alternate GRP type blades are also available including PPG, PAG PAGAS and PAGST.
