Diverters
The MacDonald Steel Air
Diverter unit is designed for use in the clean air return
duct of a filter system, to direct clean air either to the
atmosphere or return it to the building to save heat in the
winter months. Our diverters can be equipped with leak
detection/spark detection.
The modular design and square, symmetric flanges of the diverter
housing allow the flexibility of mounting in a wide range
of orientations.
Standard duct transitions and an assortment of weather hoods
are available as well as adapters to mount the diverter directly
to the outlet flange of our BC fans.
Custom fittings can also easily be fabricated to suit any
customer's needs.
The Air Diverter unit consists of a rugged steel housing
containing a pivot-mounted steel diverter blade which closes
off the unused leg of the diverter, directing the clean air
to the other leg.
The pivoting mechanism is connected to a shaft which is located
and supported on heavy-duty flange-mounted ball bearings,
for smooth operation.
Each size of Air Diverter is available in three versions:
- manually operated
- electric-motorized linear screw actuated
- electric solenoid controlled air cylinder actuated
