The all new Mini Mixed Flow Roof Fan has been especially designed for high pressure, low volume supply or extract ventilation systems, with either rigid or flexible ducting. The ACR range of fans allows the installer greater flexibility of system design, when considering access to the fan for maintenance or restricted void space. Suitable for flat horizontal roofs as standard, the ACR unit can be installed on shallow pitched roofs (20° max.) but will require additional weathering of the mounting plate when fixed to the upstand by the installer.

The ACR range of fans may be used for supply or extract ventilation systems by re-mounting the fan section in either its supply or extract mode before installation, with the added benefit of a two-speed motoras standard. The range consists of four sizes; 150, 200, 250 and 315mmØ with air volumes from 0.1 to 0.48m³/s (360 to 1,728m³/h) at free air and pressure development up to 300Pa.

Mini Mixed Flow Roof Fans are suitable for domestic and commercial applications particularly where space is at a premium or an external application is required. A full range of compatible internal accessories is available to create a variety of input or extract systems to suit individually designed schemes.
