Radial ventilators are used wherever a greater increase in pressure with the same amount of air is required in comparison to axial ventilators. The air is drawn in parallel or axially to the drive axis of the radial ventilator and is deflected by 90° and blown out radially by the rotation of the radial impeller. A distinction is made between impellers with backward curved blades (at high pressures and efficiency), straight blades (for special purposes such as particle-related flows to reduce build-up) and forward curved blades (at low pressure and efficiency). There are single-sided and double-sided suction radial ventilators with and without enclosure.
