Oil Lubricated Air Compressor 30 - 55 kW (Fixed & Variable Speed)

New Generation in Compression Technology

Single & Two-Stage

Fixed & Regulated Speed

The ALL-NEW L-Series from CompAir

Well known in the industry for quality and reliability, CompAir continuously develops the L-Series to achieve cutting-edge performance and efficiency. And so, a new era in air compression technology has begun.

More sustainable, more powerful, more energy-efficient, and also, exceptionally small.

Key Specifications

Motor Power (kW)

30 - 55

kW

Volume Flow (m³/min)

1.47 - 11.1

m³/min

Pressure (bar)

5 - 13

bar

Smaller Energy Costs, Smaller Maintenance Costs, Smaller Environmental Impact, Smaller Property Costs

Air Compressor up to 40% smaller in size

Compact Package

A core benefit of the NEW GENERATION two-stage L-Series is that it delivers much greater efficiency than single-stage compressors, but comes in a German-engineered package that is roughly the same size! Users in a variety of industries benefit from an amazing, space-saving package of just  1.19 m² (30-37kW) and 1.4m² (45-55kW) – that’s up to 40% smaller than our previous range, and smaller still than anything else on the market.

Energy Efficiency Reimagined: CompAir’s New Era in Air Compression

Interactive Tour of the L-Series

Step into the world of compressed air innovation with the CompAir360 interactive tour.

Not a “next generation” of L-Series.... It is an Industry-defining New Generation!

We are proud to introduce the ALL-NEW L-Series 30-55kW, single and two-stage, fixed & regulated speed oil-lubricated rotary screw air compressors – featuring brand new, innovative technology, engineered to provide next-level performance and efficiency for customers across a wide variety of industries. 

Conceived with passion and positivity from the whole CompAir Team. Determined that we should make a difference in the world we live. Not happy with just changing the game, we have reinvented it!

Designed and manufactured in Germany

Premium Efficiency Airends – Engineered for Excellence

Compressors are more than just a financial investment; they are a key component to ensure that manufacturers, processors and operators receive consistent, high-quality, low-cost air.

The screw compression element is the heart of the compressor, so CompAir keeps the design and manufacture in-house, using the latest CNC rotor grinding machinery, coupled with online laser technology. The resulting reliability and performance ensure that operating costs will remain low throughout the compressor’s life.

CompAir FourCore Airend

New generation FourCore airend technology

Very compact & very low weight

Highest efficiency

Semi-integrated airends two-stage with integrated oil filter, thermostatic valve and check valve:

  • Fewer hoses and hydraulic pipes = lower costs
  • No leakages
  • Easier maintenance
  • Less spare parts and waste = more sustainable

Two compression stage = vastly more efficient

Oil-cooled permanent magnet motors with cooling integrated in the airend casting

High flexibility by a two-step drive gear configuration, UNIQUE to CompAir

  • Constant interstage pressure = better efficiency
  • Extremely compact design

Designed to implement in the current L-Series, UNIQUE to CompAir

  • Fixed and variable speed models
CompAir FourCore Airend technology

High-Efficiency Electric Motor

Premium efficiency motors fitted as standard – Permanent Magnet (PM) IE5 for variable speed variants and IE4 class motors for fixed speed variants. With the patented oil-cooled motors we can recover even the small percentage of the motor’s lost efficiency by using integrated heat recovery.

Save energy with CompAir

Delcos XL SE Innovative Touch Screen Compressor Controller

The high-resolution touch screen display, is highly user-friendly and self-explanatory. Advanced control system and integrated sensors optimise the compressor to the actual working conditions, saving on energy and protecting your investment against condensate.

Embedded IoT and includes onboard web server and Base Load Select for primary function for up to three secondary units. Both the board and controller have a high level of CS Standard for cyber security. Ecoplant-ready and iConn-inside for total control and monitoring.

Delcos XL SE air compressor controller

Machine intelligence drives greater energy efficiency

Ecoplant is an AI-driven energy efficiency solution that optimises compressed air systems. It continuously monitors, analyses, and adjusts compressor operations to reduce energy waste, lower CO2 emissions, and cut costs by up to 20%. Integrated with iConn, it ensures:

  • Minimised outages & stable pressure
  • ISO quality standards compliance
  • Proactive issue detection to prevent downtime and enhance reliability
  • Optimised energy use and reduced costs
