The Helios MVP 100 B is a parallel twin-unit system featuring two swing-out MV fans connected by rectangular duct plates on both suction and pressure sides, securely attached to sturdy mounting rails. Designed as a ready-to-assemble kit, this unit enables parallel operation with joint control, effectively doubling the volume capacity for enhanced ventilation performance. Its housing is constructed from impact-resistant and corrosion-resistant light gray plastic, complete with molded mounting brackets for straightforward installation on walls or ceilings, and standard pipe-sized suction and discharge nozzles. Included in the delivery are dowels and screws for easy mounting. Each fan is powered by a closed, ball-bearing capacitor motor with moisture protection and insulation class F, suitable for continuous operation. The motors are maintenance-free, radio interference-free, and protected against overload by built-in thermal winding safeguards.
