Application
Fans designed for transporting non-aggressive and non-explosive gases. Typical applications:
- pneumatic transport,
- blowing in drying systems (e.g. graphic machines, processing of plastics),
- air blowing systems in combustion / thermal treatment systems (e.g. melting furnaces),
- for air transport in ventilation systems and technological lines,
- dust content in the transported medium up to 1g/m3.
CONSTRUCTION
- low-pressure, single-sided, direct-driven radial fan
- impeller welded from black steel sheet, backward curved blades welded from carbon steel sheet, painted with primer paint, balanced according to ISO1940-1
- housings welded from carbon steel sheet
- fans are normally painted in blue RAL5010, corrosivity class C3
- transport of a medium in the temperature range -20°C to +80°C
- standard figure LG270
