How CompAir’s New 45–55kW Range Delivers Higher Efficiency and Lower Costs

The latest generation of CompAir 45–55 kW rotary screw compressors marks a genuine step change in the world of compressed air.
Rather than a light refresh of an existing series, CompAir has engineered this range completely anew — built to consume less power, take up less space, and deliver greater performance for industries that rely on a constant, efficient air supply.

At West Midlands Compressors Ltd, we are proud to bring this new range to UK businesses seeking reliability, innovation and measurable energy savings.

Efficiency That Pays Back

Energy use represents the single largest cost over a compressor’s lifetime.
The new CompAir 45–55 kW range was built to minimise it.

A newly developed airend and high-efficiency motor work together to achieve exceptional free-air delivery with minimal energy draw.
The package design also reduces internal pressure losses, cuts noise, and lowers cooling requirements — resulting in an impressively low specific-power ratio.

Supporting this is CompAir’s intelligent control system, which uses integrated sensors to fine-tune performance in real time.
By constantly adjusting to operating conditions, it maintains stable pressure, avoids energy waste and extends service intervals.

Why It Matters to You

1. Tangible cost reduction – With power bills at record highs, even marginal efficiency gains translate into significant annual savings.
The new CompAir models are engineered to lower total ownership costs from day one.

2. Compact and flexible – The new design achieves a footprint up to 25 % smaller than many conventional compressors in the same power range.
That space efficiency simplifies installation in crowded plant rooms and allows system upgrades without costly layout changes.
Whether you are replacing an older unit or adding extra capacity, the compact layout and smart internal design make integration straightforward.

3. Lower maintenance effort – Fewer moving parts and easy-access panels speed up routine servicing, keeping downtime to a minimum.

4. Built-in protection – Continuous monitoring of condensate levels and operating temperatures helps prevent common system failures before they occur.

5. Cleaner operation – Reduced material usage, lower noise output and optimised energy consumption make this range a strong choice for companies pursuing sustainability goals.

Tailored to Industrial Demands

The 45–55 kW range meets the needs of manufacturers across multiple sectors — from automotive workshops and precision engineering to packaging, food production and pharmaceuticals.
The fixed-speed models provide stable, consistent output where demand rarely changes, while the regulated-speed versions adjust automatically to match air consumption, preventing wasted energy during idle periods.

This versatility allows production sites to maintain performance under varying loads while keeping electricity costs firmly under control.

Engineered with Foresight

The ethos behind this generation is straightforward: use less, achieve more.
CompAir’s engineers adopted a clean-sheet design that integrates:

• A compact airend to reduce energy losses and simplify maintenance.

• Premium-efficiency motors for long-term durability.

• Advanced cooling and filtration to ensure high air quality.

• Modern, quiet enclosures suitable for production environments.

• Digital connectivity for remote monitoring and performance analytics.

This blend of engineering precision and user-friendly technology defines CompAir’s approach to sustainable performance.
