L04 – L250 : 4-250KW Oil Injected Rotary Screw Compressors

A range of compressed air systems to suit all applications

Industries, both large and small, rely on CompAir rotary screw compressors for a supply of consistently high quality compressed air. Pre packaged with single connections for power supply, compressed air and built in cooling systems the installation of all CompAir L-series compressors is greatly simplified.

Screw compression elements are manufactured in-house using the latest CNC rotor grinding machinery, coupled with on-line laser technology, in order to maintain precise manufacturing tolerances. The resulting reliability and performance ensure that operating costs will remain low throughout the compressor life

New CompAir Screw Compressors with Power-Saving Motors

The redesigned L55 and L75 directly coupled CompAir screw compressors, with oil injection now need even less power. The sound-proofed compact units with double-pole, energy-saving motors now deliver 10.7 and 13.7 m 3 /min respectively, at a working pressure of 7.5 bar (rated output 55 and 75 kW, pressure range 5 to 13 bar).

The machines have been fully redesigned inside and out. The new compressor air end is manufactured at CompAir's own factory in Simmern. It contains a fully integrated oil filter and thermostatic valve giving an optimum oil injection temperature and has been built to extremely low tolerances for maximum economic efficiency.

High performance and efficiency

The high capacity compression element, with low rotor tip speeds and optimised oil injection, gives high efficiency with maximum reliability. The latest CompAir designs ensure low system and compressed air temperatures. The guarantees excellent cooling and maximum service life for all components.

A maintenance free, reliable and effective drive concept

The compression element is driven at optimum speed for the application through a high efficiency V-belt system. The unique automatic belt tensioning device ensures correct belt tension at all times, reduced loading when off load and during start up, minimises slip and is completely maintenance free during normal operation.

Low service costs

The innovative compressor design saves unnecessary service cost. All component parts are designed for a long service life. and the generously sized suction filters, oil filters and fine separators ensure excellent compressed air quality. All oil filters, and on the models up to 22kW (30hp) the separator elements, are spin on / off further minimising service time. The Quick access service points allow servicing to be conducted in minutes and minimising downtime and service costs.

Built in intelligent controls

Close operational control is essential to reduce running costs. All CompAir rotary screw compressors are supplied with intelligent, fully electronic controllers with simple controls and a user-friendly menu.
