Airflow has an extensive range of commercial fans:
Aventa 150 - mixed flow fan,
Aventa Silent - centrifugal fan,
Aventa Turbo - mixed flow fan.
The Aventa commercial units are in-line extractor fans. They are able to offer powerful extraction whilst being unnoticeable. The compact design of the Aventa commercial range grants you great installation flexibility.
Aventas have high flow/high-pressure development characteristics. This means that use with flexible ducting and flat duct systems is possible. All units within the Aventa commercial range comply with Building Regulations.
Aventa Silent supplies up to 283 l/sec whilst being quieter than a human whisper.
Refer to the CIBSE guidelines for recommended air changes per hour in non-domestic installations.
