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

MOTOR

• asynchronous 3-phase 230 / 400V, 50Hz (power up to 3,0 kW)
• asynchronous 3-phase 400 / 690V, 50Hz (power from 4,0 kW)
• IE3 efficiency class
• degree of protection IP55
• insulation class F
• adapted to frequency regulation
• motor ambient temperature from -20°C to +40°C

ACCESSORIES

• anti-vibration inlet and outlet connections
• support frame
• inlet and outlet covers
• connectors, reducers, adapters
• vibro-isolators

SPECIAL EXECUTIONS
