The Helios MVP 160 is a RADAX MixFlowVent two-stage in-line fan designed for space-saving duct installations. It features two mixed flow fans connected in series on a common base with a sleeve, effectively doubling the pressure output while maintaining the same volume flow. The fan is supplied as a pre-assembled kit for quick and easy installation. The casing is made from impact-resistant and corrosion-resistant light-gray polymer, incorporating an integrated mounting frame for effortless wall or ceiling installation. Connection spigots fit standard duct sizes. The fan unit, including the terminal box, can be rotated to any position by loosening the clips, facilitating maintenance and cleaning. The mixed flow impeller has 8 spatially curved blades made from durable polymers and is dynamically balanced to quality level G 6.3 per VDI 2060 and DIN ISO 1940 standards for quiet operation. Powered by a totally enclosed ball bearing motor designed for continuous use, the motor offers humidity protection, insulation class F, and is maintenance-free and radio suppressed. Motor protection via integrated thermal contacts is standard.
