S&P's COMPACT Wall Axial Fans have an extremely compact design created by the combination of an internal rotor motor mated with a direct drive wrap around impeller hub. This low profile design optimizes airflow performance while minimizing noise generation. The wall mounted versions require an absolute minimum depth for any given wall, ceiling or panel mounted installation.

S&P's COMPACT Wall Axial Fan was designed to be installed directly into sidewalls, ceilings and panels while exhausting or supplying air to the surrounding environments. All wall axial units include a one piece bell mouth inlet and mounting plate manufactured from high grade galvanized steel. The motor and fan impeller assembly are firmly supported within this mounting plate by a strong steel support frame that includes an integrated finger guard on the inlet side. All units are supplied with motors prewired to a wiring junction box located on the back of the motor hub for easy wiring access. This terminal box protects all wiring connections against the ingress of dust and moisture. The entire assembly is protected by a two stage primer and a tough corrosion and UV resistant polyester paint finish.

S&P's COMPACT Wall Axial Fans are designed for use in a wide range of residential, commercial and industrial ventilation applications. These units are designed to be installed directly into sidewalls, ceilings or panels. Typical applications include:

  • Residential — Garage, Loft, Workshop, Basement and Crawl Space Ventilation...
