Woods JM Aerofoil Bifurcated 400mm Cased Axial Fan 4 Pole 3 Phase - JN245011
High-quality fan designed to withstand continuous hot temperatures and with a protected motor that does not get exposed to any particles within the airstream.
• Motor mounted outside the air stream
• Suitable for continuous operation for temperatures from 100°C to 200°C
• Adjustable pitch impeller delivers precise performance
Sometimes it is required that a fan is able to operate at elevated temperatures continuously, or when there are particles or hazardous gases within the air stream that would damage a motor if it was unprotected. Bifurcated fans split the airflow around a motor tunnel which means that the motor is held outside of the airstream and therefore does not get exposed to what the air stream is carrying. Bifurcated fans are used as kitchen hood extract fans, keeping the motors protected from grease and elevated temperatures, also bifurcated fans are also used in industrial processes where air temperatures are continuously high (foundries for example) or where acids or abrasive particles are common in the airflow.
Product Facts:
• Air flow up to 0.74m3/s at 150 Pa (2671m3/hr)
• Motor protection and terminal block IP55
• Fans tested to ISO5801 and BS848
• Overheat protection available
• Motor is external to air stream
• DW172 compliant for solid fuel cooking applications
Electrical Supply:
• 380-420V/50Hz/3f
Temperature Range:
• Suitable for temperatures between 100°C and 200°C (continuous operation) - exempt from ErP legislation.
Impellers:
• A unique high efficiency aerofoil section blade with a smoothed hub and clamp plate for adjustable pitch angle availability. Woods impellers are die cast to offer thin aerofoil sections for low generation of noise. Every component is X-rayed using Real Time Radiography inspection prior to assembly. The maximum pitch angles shown allow for speed control by frequency inverter.
Motors:
• All motors are totally enclosed fan cooled class F insulation with protection to IP55 and are IE1/IE3 compliant. All motors are supplied with sealed for life bearings or extended lubricators. These motors are suitable for inverter speed control down to 20% of full speed.
Casing:
• Bifurcated fans are available long case only. Long casing covers impeller and motor and has duct mounted terminal box. The hot dipped galvanised casing gives a high resistance to corrosion. Motor is mounted inside a tunnel, so is ‘out of air stream’. Bifurcated fans for external roof mounting, please ensure the motor tunnel in mounted vertically downwards to avoid water ingress.
Temperature Range:
• If the temperature of airflow within a bifurcated fan system is excessive, Woods recommend that the fan is allowed to overrun so that any heat is removed from the system. Failure to do this could mean that heat will transfer via the shaft/casing to the motor tunnel, which could cause degradation of the grease and lead to premature failure.
