Terminal Box
To IP55, protected against dust and water jets from any angle, allowing outside applications.

Motor / Impellers

The motors are two speed dual or tap wound, specially selected for optimum performance and efficiency. Ball bearings are greased for life and allow the fan to be installed at any angle. Suitable for continuous operation in relative humidity up to 95%. Motors are protected to IP55against dust and water jets complying with BS EN 60529. They have ribbed aluminium body castings for efficient cooling. Motor insulation is Class 'F' (from -35°C to +54°C). Star/delta starting is recommended for motor output above 4kW..

Motor Support Arms
Motors are mounted by means of specially designed support arms which act as an air straightener to help minimise turbulence and maximise performance, whilst ensuring quiet operation.

Impeller blades are clamped in a split cast aluminium hub, with a keywayed mild steel insert enabling positive locking of the impeller assembly to the motor shaft, this also allows manual adjustment of the pitch angle giving a wide selection of performance details.

Electrical

Single phase 220-240V 50 Hz. Capacitor start and run. Three phase 380-415V 50Hz. Protection of the motor must be provided by an overload current sensing device (eg. D.O.L Starter or Star/Delta starter where appropriate) or the guarantee will be invalidated. All models are available with 4 pole motors for 315 up to 1250mm with additional 2 pole motors available from 315 up to 630mm.
