The Helios MVP 150 is a parallel twin-unit ventilation fan comprising two swing-out MV fans connected side-by-side by rectangular duct connection plates on both the suction and pressure sides. The units are securely mounted on sturdy rails and supplied as a ready-to-assemble kit. When operated in parallel with joint control, the system delivers double the volume capacity compared to a single unit. The housing is constructed from impact-resistant and corrosion-resistant light gray plastic, featuring molded mounting brackets for easy installation on walls or ceilings. The fan includes suction and discharge nozzles designed to fit standard pipe diameters. Installation accessories such as dowels and screws are provided. The fans are powered by closed, ball-bearing capacitor motors with moisture protection and insulation class F, ensuring reliable continuous operation. These motors are maintenance-free, radio interference-free, and include thermal overload protection built into the winding for enhanced safety.
