Lubricated Rotary Screw Compressors Compair

Compressed air is the fourth utility network of a modern enterprise after electricity, water, and gas. The quality and continuity of compressed-air supply determine the productivity of production lines, product quality, and the economic efficiency of the business. CompAir screw air compressors deliver a reliable compressed-air supply for companies across many industrial sectors.

CompAir offers a wide range of oil-lubricated rotary screw compressors with power ratings from 2 to 250 kW, free-air delivery from 0.24 to 47 m³/min, and working pressures from 5 to 13 bar.

Why Choose a CompAir Screw Compressor

A screw-type air compressor has significant advantages over piston models. Its main benefit is the absence of valves and other mechanical elements that can cause system imbalance. This ensures high-quality compressed air at high operating speeds and greater output without compromising on compact design.

Key advantages of screw technology:

Reduced maintenance — no pistons, rings, rods or other parts that require regular servicing
Low noise and vibration thanks to fewer moving parts
Continuous duty cycle — constant air delivery without adverse effects on the compressor
Premium energy efficiency due to an optimised air end design

Model ranges 2 – 250 kW

CompAir provides a complete portfolio of screw compressors for diverse industrial needs.

Series 55–75 kW (L55-L75)
Air- and water-cooled versions, plus heat-recovery option. FAD: 2.20–14.72 m³/min, pressure: 5–13 bar.

Series 90–132 kW (L90-L132)
Best-in-class efficiency thanks to a new premium air end. FAD: 5.3–24.5 m³/min, pressure: 5–13 bar.

Series 160–250 kW (L160-L290)
Innovative range with gear- and direct-drive options delivers 12 % more compressed air at the same motor power. FAD: 6–47 m³/min, pressure: 5–13 bar.

Key Advantages of the Lubricated L-Series

CompAir designs and manufactures its own screw elements using state-of-the-art CNC rotor grinding and online laser technology.

Benefits of lubricated compressors:

Full automation via Delcos controller
Automatic oil dosing in the right amount at the right time
No need for manual intervention
Quick and cost-effective servicing
Cartridge replacement at 4 000 or 8 000 operating hours
Longer service life thanks to infrequent rotor replacement

A variable-speed rotary screw compressor can efficiently and reliably handle the fluctuating air demand found in most factory air systems, delivering significant energy savings.

All models from 15 kW upward can be equipped with an integrated heat recovery system to reclaim energy otherwise lost as heat.

How to Choose and Buy a Screw Compressor

When selecting a compressor, consider several key parameters.

Determining your air demand:
Calculate maximum and average compressed-air consumption
Establish the working pressure required for your applications
Define operating mode (continuous or variable)

Selecting the drive type:
Fixed speed — efficient when demand is constant at 100 % load
Variable speed — saves energy when demand fluctuates by matching output

Additional options:
Heat-recovery system to boost energy efficiency
Cooling variants (air- or water-cooled)
Integration with plant management systems

You can buy a screw compressor after a detailed consultation with our experts, who will help select the optimal model for your technical requirements and budget.

FAQ

How many hours can a screw compressor run continuously?
CompAir screw compressors are designed for 24/7 operation with no duty-cycle limits, unlike piston models.

What is the difference between fixed- and variable-speed compressors?
Fixed-speed units run constantly and are efficient at full load. Variable-speed models adjust output to demand, saving energy.

Do screw compressors require special maintenance?
Maintenance is minimal thanks to the simple design: periodic oil, filter and separator changes as per schedule.

Which industries use screw air compressors?
Food & beverage, automotive, aerospace, electronics, pharmaceuticals, chemicals and many more.
