Complete series of centrifugal fans for air flows up to 18 m ³/s and pressure rises up to 3600 Pa. The series consists of

• direct driven, single-inlet fans
• belt-driven, single-inlet fans
• belt-driven, double-inlet fans

The fans are suitable for most ventilation and air conditioning applications onboard ships and off-shore platforms.

• High efficiency throughout the operating range
• Low outlet air velocity
• High static (useful) pressure
• Low connection losses
• Several standard versions are available, including
• with variable pitch inlet guide vanes
• spark-proof
• for smoke extraction
• Economical control by means of inlet guide vanes which can be reset at any time to adjust the fan performance to suit the system requirements - but at the same high fan efficiency.
• Low sound level

This range of duct fans comprises 11 models for standard ducting diameters 100-315 mm (incl.) The external rotor motor and impeller combination is mounted within a pre-galvanised sheet metal housing. The low noise high performance motor and impeller gives a range of air volumes from 160 m ³/hr to 1400 m ³/hr inclusive. The fan will operate against high static pressure even at relatively small air volumes.

The single phase 220/240 vold 50 Hz motor is pre-wired to an external terminal box. Motors of models CLE 100 and CLE 125 are fitted with impedance protection all other models (CLE 160 to 315) are provided with internal thermal overload protection, and are suitable for 60 Hz. Fans may be mounted in any plane. Maximum ambient operating temperatures for all models is 60 °C, except model CLE 315 which is 40 °C.

All models can be speed controlled by means of auto transformer type regulators. If so required, solid state controllers can be used for all except model CLE 315.
