Helios Fans MVP 125

The Helios MVP 125 is a two-stage RADAX MixFlowVent in-line fan designed for space-saving installation in ductwork. This pre-assembled unit features two mixed flow fans arranged in series on a common base with a connecting sleeve, providing double the pressure at the same volume flow. The casing is made from impact-resistant and corrosion-resistant light-grey polymer, incorporating an integrated mounting frame for easy installation on walls or ceilings. The connection spigots fit all standard duct sizes, and the fan unit with terminal box can be rotated to any position or removed for maintenance and cleaning by simply loosening the clips. The mixed flow impeller has eight spatially curved blades crafted from durable polymers and is dynamically balanced to quality class G 6.3 according to VDI 2060 and DIN ISO 1940 standards. It is powered by a totally enclosed ball bearing motor designed for continuous operation, featuring humidity protection and insulation class F. The motor is maintenance-free, radio suppressed, and protected by integrated thermal contacts for safe operation.
