Single inlet centrifugal fans are ventilation devices that use centrifugal force to transport air or gas. Air enters through a single inlet and is pushed outward by a rotating impeller, increasing pressure and flow rate. Structurally, the impellers feature forward-curved and backward-curved blades, typically made of galvanized steel. The motors are AC and EC, equipped with various features including thermal protection. IP54 and IP55 protection levels are common, with Class F insulation. The casing is made of corrosion-resistant steel, some with a polymer coating. They offer high performance, handling large air volumes in a small space, adjustable speed and noise control, and dynamic balancing for stable, vibration-free operation. They are used in HVAC systems for indoor air conditioning, industrial process ventilation, equipment cooling, and other ventilation applications, such as commercial kitchen exhaust and cleanroom ventilation.
