Ruck 22 Inch Prime Mixed Flow Is Three-Phase Equipment
The supply requirement decides everything else about this fan. It runs a three-phase AC motor, so a standard single-phase circuit will not power it. Given three-phase, it moves 10,800 m³/h against up to 790 Pa of static pressure, at a maximum 1,803W. Ruck quotes 64.8% total efficiency, which is high for a fan of this size.
Specifying a Mixed Flow Duct Fan at This Scale
Static pressure is the reason to choose it. That figure means it will pull through long runs, heavy filters and multiple bends without collapsing, which is where smaller fans give up. The IP55 motor rating handles dust and washdown, and the aluminium housing keeps the weight sane for the diameter. It is rated to 60°C ambient, so warm extract air is no obstacle. Plan the rigging and the electrical work together, because retrofitting three-phase to a room afterwards is expensive. A mounting bracket is included.
Key Features
- 10,800 m³/h (6,356 CFM): Commercial-scale airflow for large rooms and long duct runs.
- 790 Pa Static Pressure: Pulls through heavy filters and multiple bends without stalling.
- Three-Phase AC Motor: Industrial supply required; it will not run on a single-phase circuit.
- 1,803W Maximum: The published ceiling, so the supply and protection can be sized.
- 64.8% Total Efficiency: A high figure for this diameter, which shows in the running cost.
- IP55 Motor: Rated against dust and jets, suitable for washdown environments.
- Aluminium Housing: Keeps weight manageable at 22 inches and resists corrosion.
