RH63M-VDK.7Q.1R Ziehl-Abegg 400V 630mm AC Centrifugal Fan

Description

The Ziehl-Abegg RH63M-VDK.7Q.1R is a high-performance 3-phase AC Centrifugal Fan featuring a 630 mm backward-curved Cpro impeller, precision-engineered from fiberglass-reinforced composite material. Powered by the high-torque MK165-VDK.14.U external rotor motor, this unit operates on a 400 VAC supply (Delta/Star) and is optimized for the most demanding AHU (Air Handling Unit) and FanGrid applications. It delivers a maximum airflow of 14,350 m³/h at a rated speed of 1230 RPM (50Hz, Δ-connection). The Cpro series is renowned for its bionic blade geometry, which minimizes acoustic turbulence and maximizes static pressure efficiency (up to 750 Pa). With a maximum power input of 2.6 kW and IP54 protection, this 31.5 kg module provides 24/7 mission-critical reliability for 400V global industrial infrastructures, offering superior chemical resistance and reduced rotational inertia compared to traditional steel impellers.

Application
The Ziehl-Abegg RH63M-VDK.7Q.1R is the definitive air-moving solution for medium-to-large scale Air Handling Units (AHU), industrial data center cooling, and clean-room recirculation systems. Its 630 mm Cpro composite impeller is specifically engineered for low-noise operation and high resistance to aggressive environments, making it ideal for hospital ventilation and pharmaceutical production areas. The 400V 3-phase dual-speed (Δ/Y) capability allows for flexible integration into building management systems (BMS), enabling high-performance airflow at 1230 RPM or high-efficiency, reduced-noise operation at 890 RPM. With its 31.5 kg robust construction and H1 moisture protection, the RH63M provides high-velocity, reliable heat rejection and climate control for global 50/60 Hz industrial power grids.
