CompAir L05 Rotary Screw Air Compressor
The CompAir L05 is a lubricated rotary screw air compressor built for smaller businesses and industrial applications that need consistent, dependable compressed air. It sits within CompAir’s L-Series, a range focused on compact installation, straightforward operation and service accessibility.
This model uses a 5.5 kW (7.5 HP) motor and is available at 7, 8 and 10 bar. Free air delivery is listed at 0.68 m³/min at 7 bar, 0.67 m³/min at 8 bar and 0.66 m³/min at 10 bar, allowing the pressure specification to be matched more closely to the application.
For buyers moving away from an ageing piston compressor, the L05 offers a compact rotary screw option for regular workshop and light industrial use. Removable side panels provide access to service points, while the 68 dB(A) listed noise level supports installation in many working environments, subject to correct siting and ventilation.
Who Is The CompAir L05 Best For?
The CompAir L05 is best suited to smaller applications that need a dependable supply of compressed air from a compact rotary screw compressor. Correct sizing should be based on required airflow, pressure and the site’s actual demand profile.
This model is a strong fit for:
- Workshops running pneumatic tools throughout the day
- Vehicle repair centres and bodyshops
- Engineering workshops
- Small to medium manufacturing sites
- Light industrial units
- Maintenance departments
- Sites replacing an older piston compressor
- Businesses that need a compact 5.5 kW screw compressor
For example, a workshop using pneumatic tools at regular intervals may be well suited to the L05. Garages, engineering environments and light industrial sites can also benefit where the required airflow sits within the L05’s operating range.
If air demand varies significantly or the site requires substantially more airflow, CJS Direct can help compare the L05 with other CompAir models and variable-speed options. The key is to size the compressor around measured demand rather than motor power alone.
Key Benefits Of The CompAir L05
Reliable compressed air for daily use
The L05 is designed to provide reliable compressed air for workshops, garages and light industrial applications. Its rotary screw design supports regular operational use where dependable air supply is important.
Compact design for practical installation
The L-Series is designed around a compact footprint, helping businesses install a rotary screw compressor where plant-room or workshop space is limited.
Low-noise operation
With a listed noise level of 68 dB(A), the L05 is designed for relatively quiet operation. Final placement should still consider site layout, ventilation and operator comfort.
Easier servicing access
The L05 uses removable side panels to provide straightforward access to service points. This can make routine inspection and planned maintenance easier for service engineers.
User-friendly operation
CompAir positions the L-Series as a user-friendly, plug-and-play range for smaller applications. Controller and starting arrangements can vary by configuration, so the final specification should be confirmed before ordering.
Package flexibility
The L05 can be supplied as a base-mounted compressor, on a 270 litre or 500 litre receiver, or as a complete Air Station with receiver and refrigerant dryer. This allows the system to be matched to the site’s storage and air-treatment requirements.

CompAir L05 Range Options
The 270L receiver-mounted L05 combines the compressor and air receiver in one package. It can be useful where stored air is required while keeping the installation relatively compact.
The 500L receiver-mounted L05 provides greater stored-air capacity and may suit sites where additional receiver volume is beneficial to the system design.
The L05 Air Station combines the 5.5 kW compressor, a 500 litre air receiver and a refrigerant dryer in an integrated package. It is intended for businesses that want a more complete compressed air solution with clean, dry air and simplified installation.
Where air quality is important, an optional filter pack may be required. This can help protect downstream equipment and support cleaner compressed air for applications where moisture, oil carryover or particulates need to be managed.
Pressure Options And Air Output
The CompAir L05 is offered in multiple pressure configurations so buyers can match the compressor more closely to the needs of their equipment and compressed air system.
| Lower pressure requirement | Higher pressure requirement |
|---|---|
| 7 bar option | 10 bar option |
| Highest listed L05 airflow: 0.68 m³/min | Listed airflow: 0.66 m³/min |
| Suitable where equipment does not require higher pressure | Suitable where downstream equipment requires higher pressure |
| Can reduce unnecessary pressure generation when correctly specified | Allows for applications with a genuine higher-pressure requirement |
| Confirm system losses and point-of-use pressure | Do not select higher pressure than the system requires |
The CompAir L05 is available in 7, 8 and 10 bar configurations. Choosing the correct pressure matters because the required working pressure affects both compressor selection and available airflow.
At 7 bar, the L05 is listed at 0.68 m³/min (24 CFM). At 8 bar, output is 0.67 m³/min (23.6 CFM), while at 10 bar it is 0.66 m³/min (23.3 CFM). The compressor should be selected around the pressure actually required at the point of use, allowing for system pressure losses.
Common Applications of the CompAir L05
Air tools in workshops
The L05 can support regular use of pneumatic tools in engineering, maintenance and repair environments, subject to correct sizing against simultaneous air demand.
Vehicle repair and bodyshops
For garages and bodyshops, the compressor can provide a stable air supply for common workshop tasks, subject to correct sizing and air treatment.
Spray booths and paint shops
Where compressed air is used for spraying, the correct dryer and filtration setup is especially important. The L05 Air Station or additional air treatment may be appropriate depending on the required air quality.
Packaging equipment
Small production and packaging lines often need dependable compressed air for repetitive processes, actuators and general plant operation.
CNC support equipment
Compressed air is often used to support CNC machinery, tool changes, cleaning and ancillary equipment.
General plant air
The L05 can be used as a general plant air compressor for smaller industrial premises where its pressure and airflow range matches site demand.
Installation, Servicing And Support
A compressor should not be selected in isolation. To get the best performance from the CompAir L05, it needs to be installed as part of a correctly specified compressed air system.
Before purchase, CJS Direct can help review:
- Required air flow and working pressure
- Existing compressor performance
- Electrical supply
- Ventilation and cooling requirements
- Receiver size
- Dryer and filtration requirements
- Pipework condition
- Condensate management
- Installation access
- Service and warranty requirements
Correct installation helps protect the compressor, improve system reliability and reduce the risk of avoidable downtime. Ventilation is particularly important, as air-cooled compressors need suitable airflow to operate properly.
Planned servicing is also essential. The L05 should be maintained using the correct oil, filters, service kits and genuine parts where required. Regular servicing can help protect performance, support warranty conditions and extend the working life of the compressor.
CJS Direct lists servicing, maintenance, written scheme of examination, leasing and hire among its compressed air services, making it a useful supplier for businesses that need more than just the compressor unit.
