actiro's DNA is rooted in the development, design and manufacture of fans. Our range includes all radial fan geometries up to a diameter of 900 mm. By deploying various technologies, we are able to offer you economic solutions for small batches through to large-scale production.
What we offer:
These impellers have a ratio of 0.15 to 0.5 between the intake opening diameter and the external diameter, depending on the flow rate and pressure. The angle of the blades determines the total pressure and the static pressure ratio for a given external diameter and revolution speed.
Medium- and high-pressure impellers usually have backward curved blades. There are designs with flat or drawn cover plates.
Cylindrical rotor fans are ideal for high-volume flow rates, with revolutions of up to 7,000 min-1. The ratio of inflow to outflow is the lowest, at around 0.7 to 0.95.
The material is selected depending on the intended use of the fan. The selection depends on the medium being transported, the temperature and particles in the service air. Aluminum, steel alloys, stainless steel and ceramic coatings are ideally suited.
