Residential fans below 30 watts remain out of scope of testing by the ErP directive but will require a FISCHE.

Commercial Fans

Unlimited Applications

AIRFLOW'S extensive range of extract fans are not just for domestic dwellings. Their outstanding performance, ease of installation and aesthetic appeal ensures that they can efficiently complement virtually any installation and help comply with the Building Regulations for non-domestic installations.
Refer to the CIBSE guidelines for recommended air changes per hour in non-domestic installations

To calculate the volume of air that the fan needs to extract to satisfy the air changes per hour criteria follow this simple procedure.

  1. Calculate volume of room in m3 (H x W x L) i.e. 3m x 2.5m x 2m = 15 m3
  2. Multiply by required air changes per hour i.e. Offices = 6
  3. Volume x Air Changes per hour = Fan performance (minimum) 15 m3 x 6 ach = 90m3/hr
  4. Select a fan of suitable performance bearing in mind any ductwork resistance
