APPLICATION

The fan is designed for transport systems of non-aggressive and non-explosive gases without pollution.

Typical uses are:

• pneumatic transport
• blowing in drying systems (e.g. graphic machines and processing of plastics)
• air blowing systems in combustion / thermal treatment systems (e.g. melting furnaces)

CONSTRUCTION

• medium-pressure centrifugal fan with direct drive
• riveted impeller made of aluminum sheet, with backward curved blades, dynamically balanced according to ISO 1940-1
• die-cast aluminum housing
• galvanized inlet cover
• motor support on the 600 model
• painted gray RAL 7042
• maximum temperature of the transported medium 80°C
• figure LG270

MOTOR

• asynchronous, single-phase, 230V, 50 Hz (power up to 1,5 kW)
• asynchronous, three-phase, 230/400V, 50 Hz (power up to 3 kW)
• asynchronous, three-phase, 400/690V, 50 Hz (11 kW)
• efficiency class IE3 (from 0,25 kW) or IE2 (1,5 kW, 230V)
• degree of protection IP55
• insulation class F
• for frequency control (three-phase motors)
• for voltage regulation (single-phase motors with power from 0,37 to 0,75kW)
• motor ambient temperature from -20°C to +40°C

SPECIAL EXECUTIONS

• optional configuration LG/RD
• color other than standard
• impeller made of galvanized steel sheet
• impeller made of stainless steel 1.4301
• impeller made of acid-proof steel 1.4404
• motor with voltage and frequency of power different than standard
• motor with other than standard degree of protection
• motor equipped with sensors or additional cooling
• sealing between the housing and the motor
• motor ambient temperature range below -20°C and above +40°C
