Using ambient air, the cold air blower generates 860 km/h (535 mph) wind and 19,500 cfm of airflow to clear accumulating snow, ice and hard-packed snow from switches, third rails, and tracks without creating any condensation.

The new AF1 EVO version provides flexibility to save time and increase equipment usability. The AF1 EVO allows driving long distances on public roads without special permits, enabling you to clean and prepare different rail sites with a single man. On the market for over 25 years, the AF1 cold air blower system has proven to be an effective winter fighting machine and has become the backbone of railway maintenance operations of major rail companies and transit authorities.

Self-contained and removable module

Completely self-contained, the cold air blower module is engineered to be rapidly removed from its carrier at season change.
AF1 EVO cold air blower flexible module - RPM Tech

Multipurpose carrier

The AF1 EVO is mounted on a rugged Peterbilt 520 utility truck, available in single and tandem axle configurations. Once the AF1 EVO module is removed, the carrier can be put at work all year round when equipped with other deck truck equipment.
Ergonomic controls - AF1 EVO cold air blower for rial and airport runways

Nozzle positioning for traveling mode

For traveling mode, the nozzle is positioned and locked in the rear providing better visibility to the operator.

Operator safety

The AF1 EVO doesn’t require additional personnel on the ground to guide operations and includes many features reducing risks of accidents.

Independent fuel tanks

The blower module and the carrier have independent fuel tanks to avoid accidental carrier running-on-empty situations while working on the railway.

High efficiency design

The powerful air jet, generated by a three-stage high-performance centrifugal fan driven by a diesel engine via a clutch, requires less maintenance and consume less fuel.
