Product description

Radial fans with high pressures and lower capacities. Widely used where pressure is required, i.e. the installation due to the nature of the process creates high resistance.

Available in figures: Rd 0, 90, 270 and Lg 0, 90, 270
Inlet diameters: 100 – 350mm.
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 as standard suitable for speed control by a frequency converter.
Drainage for figures requiring them
Sophisticated solutions for easy attachment and transportation of the fan to the work site
