AIRFAN® Thermo Foam Box 1500 m³/h is a powerful sound-insulated centrifugal fan for efficient ventilation of indoor spaces, greenhouses, and professional climate control systems. The model delivers a maximum airflow of 1500 m³/h and is equipped with a Ø250 mm inlet and outlet for easy connection to air ducts and carbon filters of the same diameter.

The fan is housed in a casing made of EPP (expanded polypropylene), which limits the transmission of noise and vibration. The material is lightweight, durable, and moisture-resistant, making the Foam Box design practical for prolonged use in ventilation systems.

Efficient ventilation with lower noise levels

The centrifugal AC fan is designed for continuous operation and delivers a stable airflow when used with air ducts, elbows, carbon filters, and other ventilation system components.

With a maximum airflow of 1500 m³/h, the model is suitable for spaces that require powerful air exchange while also seeking to reduce noise and vibration compared with a standard fan in a metal casing.

Speed control

The AIRFAN Thermo Foam Box uses an AC centrifugal motor and runs at full power when connected directly.

If needed, the airflow can be adjusted using a suitable external speed controller or thermostat, allowing ventilation to be adapted to the specific conditions in the room.
