LCR - Run and Standby Axial Fans

Description

Overview

The Run and Standby Long Case Axial range of fans incorporate pre-adjusted impellers which provide a comprehensive range of duties offering high performance and pressure characteristics. Available in twelve sizes ranging from 315 to 1250mm diameter and performances up to 35m³/s (126,000m³/h) with pressure development up to 1000Pa. The casings are constructed from rolled steel plate complete with flanges and protected with a tough, galvanised finish.

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

Motor / Impellers

The motors are 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 IP55 against 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 that helps minimise the 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 factory adjustment of the pitch angle giving a wide selection of performances.

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.
