Model Overview
The COMPACT Duct Axial Fans feature 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. DA's are designed to be installed in-line with inducted or partially ducted ventilation systems for exhaust or supply air applications.
All DA's feature cylindrical flanged casings manufactured from a high grade rolled galvanized steel plate. The motor and impeller assembly is firmly supported within the casing by a strong steel support frame. All models are supplied with a pre-wired junction box located on the outside of the fan casing 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 tough corrosion and UV resistant polyester paint finish.
