HAC & QHAC Horizontal Air Curtains Air Curtains

Fastrax® HAC Series Horizontal Air Curtains produce a high velocity curtain of ambient air to prevent the accumulation of ice and snow from entering switches. These cold air snow clearing devices consist of a compact blower unit and ducting system that delivers airflow to the switch mechanism. The blower unit is an electrically powered centrifugal fan equipped with a low velocity air intake. The blower output is ducted below the rails to nozzles mounted within the railway switch. From the two nozzles, 120 - 140 mph high velocity air streams are directed towards the point of the switch.

Fastrax® QHAC Series Quiet Horizontal Air Curtains are designed for use in residential areas, with reduced sound pressure levels below 60 dbA at 50 feet.
