S&P 18 inch matching flange for DA-18 The S&P COMPACT WALL and DUCT AXIAL FANS feature, as the name suggests, an extremely compact design created by the combination of an external rotor motor matched with a direct drive wrap around an impeller hub. This very low profile design optimizes airflow performance while minimizing noise generation. Both wall and duct mounted versions require an absolute minimum depth for any given wall, ceiling, panel or in-line duct mounted installation. The COMPACT WALL AXIAL FANS are designed to be installed directly into sidewalls, ceilings or panels. The COMPACT DUCT AXIAL FANS are designed for installation within ducted systems where the fan is supported on both sides.
