Both the PK200-A with its German ebmpapst RadiCal impeller and the highly efficient The PK200-L and PK200-2, equipped with Swiss mes impellers, are among the InLine radial fans with backward curved blades. This allows for a large air flow, especially at low pressure, and This is achieved with extremely low noise emissions. The quality motors with their precision ball bearings, as well as the aerodynamically optimized shape of the impellers made of glass fiber reinforced Plastic. The extremely impact-resistant and durable housing made of polyamide (nylon) is Germany according to automotive standards. The connection and Control technology, as well as the already assembled Schuko connection cable make commissioning particularly easy. The included mounting bracket enables perfect positioning on the Wall or ceiling.
