21AF.1 Battery-Powered Positive Pressure Ventilator

The TYPHOON 21AF.1 positive-pressure fan is a battery-powered solution designed for operations requiring immediate deployment—without electrical cables, fuel, or a hydraulic power source. Its 1,000 W DC motor delivers an airflow of 12,000 m³/h to quickly ventilate buildings, utility rooms, and work areas.

Powered by a removable 48 V lithium-ion battery, it offers an operating time ranging from 60 minutes to 12 hours, depending on the selected speed setting. Supplied with its charger, it is a solution particularly well-suited for fire departments and industrial sites seeking mobile, quiet, and immediately available equipment.

Self-contained ventilation that’s immediately operational

The TYPHOON 21AF.1 can be deployed without unrolling cables, starting a generator, or setting up a water supply. Once the battery is installed, its quick startup allows positive-pressure ventilation operations to begin immediately.

This self-contained design makes it easy to use in buildings without accessible power outlets, at remote sites, or in areas where cables on the ground could hinder responders’ movement.

Autonomy Adaptable to Ventilation Needs

The 48 V lithium-ion battery provides a runtime ranging from 1 hour at full power to up to 12 hours at reduced power. This allows the operator to adjust the fan’s performance to the duration and intensity of the operation.

A full recharge takes approximately 3 hours using the included charger. An 8 A fast charger and an additional battery can also be used to increase equipment availability during extended or consecutive operations.

Exceptionally Versatile Positioning

Its adjustable tilt range from -90° to +90° allows the airflow to be precisely directed toward an opening, a stairwell, a basement, or an elevated area. This range also facilitates its use for horizontal, vertical, or downward ventilation.

The fan is mounted on a fixed frame equipped with a carrying handle. Weighing 25 kg including the battery, it offers a good balance between stability, power, and operational mobility.

FAQ – TYPHOON 21AF.1 Positive Pressure Fan

What is the actual runtime of the TYPHOON 21AF.1?

Operating time varies depending on the speed setting: approximately 60 minutes at full power and up to 12 hours at reduced speed.

Can the battery be replaced during an operation?

Yes. The 48 V lithium-ion battery is removable. Using a spare battery allows you to extend the operation without waiting for the first one to recharge.

Is the charger included with the fan?

Yes. The TYPHOON 21AF.1 comes with a 100–230 V AC / 48 V, 4 A charger. An 8 A fast charger is also available as an option.

What is the purpose of the adjustable tilt range from -90° to +90°?

It allows you to direct the airflow toward an elevated opening, a staircase, a basement, or a lower-level area without having to completely reposition the fan.
