Radial fans

Medium-pressure radial fans with high capacities. Equipped with impellers that guarantee flows over a wide operating field. They convey large volumes of air at pressures higher than the “WPL” series. Also suitable for filtration and dedusting processes.
Available in figures: Rd 0, 90, 270 and Lg 0, 90, 270
Inlet diameters: 250 – 630mm
Air flow temperatures: -20 to +80°C
Motor operating temperatures: -20 to +50°C
Installed motor powers: 0.55 – 30kW
Motor speeds: 3000, 1500, 1000 min-1
Motors adapted as standard for speed regulation by means of a frequency converter
Drainage for figures requiring them
Sophisticated solutions for easy attachment and transportation of the fan to the work site
Casing protected against corrosion – powder coating
