The ducted fan is used for exhausting headings and panels for continuous mining methods.
Installation options include skid, track, monorail and wheel mounting, the fans are suitable for towing into position and are mounted on an integral base frame fitted with wheels at the discharge end and a jacking system at the inlet end, a protection frame surrounds the fan providing mechanical protection.
Units are available in three configurations including a high pressure design with a maximum air flow of 22 m3/s and maximum pressure of 9.3 kPa.
Designed for high availability and long life, the robust design incorporates solid fan blades to minimise imbalance trips and damage when foreign object enter the fan.
The solid steel sub frame is designed to prevent flex under operating conditions or when it is installed on uneven ground ensuring the integrity of the machine and its components during operation.
The heavy duty in house designed and manufactured jack shaft and long life heavy duty bearings provide superior operating life and are not subject to skidding.
All Beckair auxiliary fans are fitted with electrical equipment designed by the Becker Mining engineering team, and are manufactured tested and commissioned at our Moss Vale ISO9001/AS3800 certified workshop.
The FS5 electrical enclosure designed for a hazardous area (Group I Zone I) has a large window for viewing operational status and diagnostic information via a HMI and contains power and control equipment.

A solid centrifugal impeller is located on an inline shaft which is coupled to a flameproof 1000VAC flameproof motor which is out of the air stream. The variable inlet vane (VIV) and air dilution valve (ADV) are high efficiency low maintenance designs, the VIV guides the air flow on to the impeller and the (ADV) robust design avoids damage when debris passes through the fan. Stone drop out boxes are located on either side of the ADV to remove debris that may accumulate during operation from the fan inlet.
Ventilation control is achieved with variable Inlet vanes (VIV) that are fitted for the air volume adjustment with calibrated and stamped VIV positions.
The fan is fitted with an air dilution valve (ADV) which is used to dilute plugs of methane gas that may accumulate in the ventilation tubes after a fan stoppage.
