Benefits
An investment that pays off
The E-Models of the L-Series feature an extra large airend with optimised rotor tip speed achieving up to 6% energy savings.
The largest cost component of a compressor is the energy to run it. The reduction of energy costs significantly impacts on the total costs of ownership.
The additional investment costs for this range of super efficient compressors will pay back in many cases in less than 12 months. The extra large airend also has a longer life expectancy.
Regulated speed compressors
The regulated speed models can efficiently and reliably handle the varying air demand found in most plant air systems. The annual cost of ownership can be significantly reduced using regulated speed technology.
CompAir RS features are your benefits.
The L-RS Series products are designed to obtain the greatest efficiency across the entire operating range.
Wide regulation range – No cycles means substantial energy savings.
Perfect motor – drive – airend design – High efficiency across broad flow range.
Design
Exceptional reliability and performance
- Large surface after cooler
Optimum cooling to ensure low operating and discharge temperatures. - Next generation separator filter
Amply dimensioned filtration for constant performance throughout the lifetime delivering an oil carryover of less than 3ppm. - High efficiency electric motor
The compressors are equipped with an energy saving IE4 electric motor as standard. - Thermostatically controlled motor driven fan
Highly efficient and extremely quiet fan allows compressor operation in the work place, plus the use of maximum duct length without further assistance. - Highest quality connections
Solid hoses and pipe connections with viton victaulic couplings increase reliability and are easy to maintain.

The controller’s real-time clock enables users to start and stop their compressor at preset times. This allows the system to be pressurized prior to production, meaning users can have instant availability of compressed air.
The second pressure setting matches compressor flow to plant demand, reducing compressor idling, and also enabling two DELCOS XL units to be sequenced without the need for additional equipment.
The controller’s service diagnostics feature enables compressor inputs and outputs to be tested, and provides quick identification of any faults, which can result in reduced downtime. A detailed analysis of up to 64 faults can be stored by the controller, providing information including the time, date, temperature and pressure of the compressor when each fault occurred.
As well as on-site monitoring, the controller can also communicate with external interfaces, such as a PC, allowing for the remote control of the compressor, and in the event of a power failure, it can be set to automatically restart the compressor.
