Bifurcated Fans

Bifurcated Fans are direct driven axial fans where the motor is encased in a metal box to isolate it from the airflow. This makes bifurcated fans ideal for exhausting or recirculating fumes, gases and hot air up to temperatures of 200°C in standard form or 300°C for our high temperature bifurcated range. The motor must have access to ambient air. The fans have non-overloading characteristics.

Woodcock & Wilson manufacture two types of bifurcated fan, spun bifurcated and fabricated bifurcated. The type of bifurcated fan refers to the process used in it's manufacture, this does not affect the fan design or performance but determines the sizes available and the materials from which the fan can be manufactured.

Arrangement Direct Driven
ATEX ATEX (II 2/3/G/D T1-T6) specification fans available for hazardous areas.
Motors In most instances foot mounted T.E.F.C. electric motors are fitted with metric dimensions to BS3979. The motors are selected to cover the 'peak' power absorbed for fan blade pitch angle and speed. Most standard motors have Class F insulation and are suitable for operating at temperatures of up to 50°C (122°F). Higher temperatures available if required.

The standard voltages are 220, 220/380, 380, 240/415 and 460. Motors can be wound for any voltage and frequency and also for dual voltage. The use of standard foot mounted motors of this type guarantees interchangeability in most countries of the world with machines of similar speed/power.

EExd Zone 1, single phase, 2/3 speed and company specification motors can always be obtained.
Impellers:
150 – 1250mm diameter
Impellers have aerofoil variable pitch Aluminium blades fitted into a die-cast Aluminium hub.

Five different blade angles are available and each blade is individually replaceable in the event of breakage.

All sizes of impellers can be supplied with varying number of blades to suit the application. This has the effect of reducing the static capability of the fan whist retaining a high efficiency.
