Oil free air and gas provide the backbone of modern industry. All of our high pressure reciprocating air compressors are designed to deliver outstanding levels of efficiency, quality, and output.
Our unique combination of shaftless motors with diagonal cylinder lines eradicates items that require regular maintenance, such as horizontal cylinder lines and belt drive systems.
Our high pressure air compressors are designed to operate for 8,000 hours between service, and when routine maintenance time comes around, you’ll find key components are easy to access and work on, so you’ll be up and running quickly.
We understand what matters. That’s why our high pressure air compressors are built to offer you maximum efficiency, reliability and uptime.
A combination of unique design features and engineering refinement adds up to real advantages for customers – including reduced energy consumption, greater uptime, lower total cost, and the sheer reliability of air delivery, when the pressure is on.
In industry, success depends on fine margins, and efficiency matters. With our machine efficiency, maximised by our shaftless motor offering the lowest running costs on the market, you can be sure that a Belliss & Morcom high pressure air compressor will maximise your profitability.
The smallest issues with the transfer of power from the compressor motor can result in significant energy loss, and serious financial impact. In fact, belt drive system inefficiencies can add up to 12% to energy bills. Which is why Belliss & Morcom high pressure air compressors are specified with a shaftless motor as standard.
This means that 100% of the motor’s output power is transferred directly into the high pressure air compressor’s running gear, with zero degradation over the lifetime of the equipment. So you start by saving, and you continue saving, year after year.
The Belliss & Morcom shaftless motor requires no drive system maintenance. No belt tensioning, no belt replacement, no motor alignment, no coupling checks or maintenance – this is a zero-maintenance drive system providing a constant and 100% efficient power transmission.

In key operational environments, every minute of available production matters. Routine service downtime eats into profitability. Through our unique diagonal design, Belliss & Morcom compressors remove the need for costly interim servicing and maintenance.
In order to ensure reliability, every component must be carefully matched to the compressor duty. Compromise is a false economy, and simply aiming for the lowest possible cost is often counter-productive for the customer in the long run.
For example, many competitor high pressure air compressors rely on heavy welded base frame assemblies to provide support or dampen very high vibration levels. And while this can be cheaper to manufacture than a fully balanced air compressor, it adds extra components which are vulnerable to unexpected and expensive failure. In contrast, the Belliss & Morcom diagonal frame design requires no external supports for structural integrity or vibration damping, and minimises wear and tear. As a result, you benefit from longer intervals between planned service, and a reduced risk of machine failure and unplanned downtime.
Belliss & Morcom has been a industrial high pressure air compressor manufacturer since 1852. Our continuing commitment to outstanding build quality and dependability is backed up by our 5 year+ Belliss Xtra warranty programme.
High pressure air compressor motors offer maximum reliability and deliver maximum efficiency when running at 75%-95% of their rated value. Running above the rated value means higher power costs and increased risk of breakdown. Unlike other equipment on the market, every Belliss & Morcom motor is specified with its full-service factor, so you can be confident that it will run continuously and at maximum efficiency throughout its full design life.
In harsh environments, at high altitudes or temperatures, where it is dusty or ventilation is limited, air-cooled motors can de-rate or even fail. Belliss & Morcom’s bespoke water cooled motors eliminate this risk. With IP56 protection and a cooling system that doesn’t rely on or impact the surrounding environment, our water cooled motors can run reliably where an air cooled motor can’t.
The unique Belliss & Morcom ‘W’ design means each compression stage runs on its own cylinder line. This gives you an extra layer of reliability and efficiency. So whatever your system size and output, capacity control can be achieved in the most cost effective way possible.
Our efficient 50% load system manages smaller flow variations and allows tighter pressure bandwidth without the need for a variable speed drive (VSD). However, where required, Belliss & Morcom high pressure air compressors also offer a market leading VSD system. Combined with our 50% load and available running speed range, it offers unmatched output control - down to 30% of the maximum output.
Belliss & Morcom high pressure air compressors feature a 45 or 60 degree incline. This reduces static piston ring loading by up to 29.3% compared with horizontal cylinder lines. It means less wear and completely eliminates the need for interim turning of either compression or bearing rings.
Ease of Access
As a result, our engineers have been able to move the largest piston off the vertical cylinder line, significantly improving access and reducing service complexity and downtime.
We offer a range of additional features designed to offer your plant enhanced levels of monitoring, control and cost savings.
High Efficiency Water Cooled Motor
The unique Belliss & Morcom water cooled shaftless motor drives the most reliable and energy efficient high pressure air compressor system on the market - ensuring reliability in the most difficult operating conditions, and helping reduce your energy bills and carbon footprint.
