Rectangular In-line Duct Fan

Setting high success benchmark so far, we are engaged as manufacturer, supplier and exporter of Rectangular In-Line Duct Fan in Pune, Maharashtra, India. As a follow-on from the in-line circular duct fan, Hans Ostberg invented in the middle of the 70's the rectangular in-line duct fan, using an in external rotor motor but having a straight-through airflow (registered design no. 32838). Thanks to the 90A angle of the airflow on the inlet side, the casing height is only a couple of centimetres more than the duct dimensions. All rectangular in-line duct fans from AB C.A. Ostberg have swing-out motor and impeller assemblies for ease of maintenance and cleaning. We at AB C.A. Ostberg are committed to giving everyone the opportunity of a better indoor climate. Our products do this by extracting the stale air and replacing it with clean air.
