Product Description
Low-pressure radial fans. Designed and intended for high-volume airflow. They are equipped with impellers featuring backward-curved blades, which give them very high efficiency. They have large inlet diameters relative to the fan’s overall dimensions.
- Available in models: RD 0, 90, 270 and LG 0, 90, 270
- Inlet diameters: 250–630 mm.
- Airflow temperatures: from -20 to +80°C
- Motor operating temperatures: from -20 to +50°C
- Installed motor power ratings: 0.25 – 30 kW
- Motor speeds: 3,000, 1,500, 1,000 min-1
- Motors are designed as standard for speed control via a variable frequency drive.
- Drainage systems for units requiring them
- Well-designed solutions for easy attachment and transport of the fan to the work site
- Corrosion-resistant housings—powder-coated.
Optional configurations:
- models other than standard ones, (RD 45, 135, 180, 225, LG 45, 135, 180, 225)
- design: IM V1 – mounted on the inlet flange
- with thermal insulation
- with acoustic enclosure
- non-standard flow rates
- motors with power ratings up to 132 kW
- double-suction (doubled capacity)
- explosion-proof for explosive atmospheres inside the fan
- explosion-proof for explosive atmospheres inside and around the fan
- high-temperature models, max. temp.: +250°C
- with vibration isolators
