Product Details:

CompAir's 55 to 75 kW screw compressor range has been enhanced with 2 additional "e" models offering improved performance in this kW size while at the same time being around 10% smaller than comparable machines.

Product Details:

The 90 - 132 kW range of lubricated screw compressors comprises of fixed speed and regulated speed (RS) models. Ingersoll Rand has unveiled its newest oil-lubricated compressors for its leading CompAir L-Series range, offering best-in-class efficiency.

Product Details:

Energy efficiency was the key focus of the development of this recent compressor range. The high-output in-house made airend with slow rotational speed reduces significantly the energy costs. In addition to this, the innovative design of the fail safe shaft seal, integrated oil filter and oil regulation valve, ensures external hoses are reduced to a minimum to guarantee the highest levels of quality and reliability are achieved.

Product Details:

The design concept is based on absolute reliability and flexibility. This range incorporates the latest technological advances and components which are designed for long service life to offer operators total piece of mind. The availability of a wide range of different version and options makes them suitable for almost all applications. This ranges from additional regulated speed models, receiver mounted versions including refrigerant dryer (Airstation) and integrated heat recovery option.

Product Details:

The new versatile screw compressor range from 30 to 45 kW can be configured to meet the customers' efficiency requirements. The E-models feature a larger airend delivering highest efficiency levels.

Well known in the industry for quality and reliability, CompAir continuously develops the L-Series achieving cutting edge performance and efficiency.

Product Details:

L02 - L06, Flow: 0.18 to 0.89 m³/min, 10 bar low-noise compressors, receiver mounted with refrigerant dryer options available.

To meet the requirements of the individual customer demands the range of compressors can be combined with numerous options to provide everything from a stand alone compressor, receiver mounted or complete Airstation including refrigerant dryer.

Refrigerant dryers are the most common type of drier technology used by many industries. As the name suggests, heat exchangers are used to cool compressed air which will condense the bulk amount of water vapour within the air. Once the compressed air is cooled and water is removed, the air is reheated to around room temperature to ensure no more vapour forms within the pipe system. In the above image from left to right you can see the air compressor, air tank (to store the compressed air), the refrigerant air dryer and the condensate management on the far right to collect the water and oil removed from the compressed air.

CompAir refrigerant dryers are manufactured in-house at our Fogliano plant, Italy where they use the latest cutting edge technology to produce maximum energy efficiency in the drying process, in other words to use as little energy as possible to complete the air drying process. Our comprehensive dryer ranges offer a host of benefits to the user including:

• High quality heat exchangers with low pressure losses
• Energy saving mode – shuts dryer off during low loads
• Full feature, multi-function innovative control panel
• Anti freeze mode – shuts dryer off to avoid icing
• Low operating costs
• Compact design
• Alarm display with history of alarms
• Effective condensate separation
• Easy to install, operate and maintain
• Simplified access to unit for easy maintenance

Our refrigerant dryers deliver a comprehensive, cost-effective solution to multiple applications across a wide range of sectors including automotive, manufacturing, petrochemical, oil and gas, dry cleaning and light processing to name a few, many 1000's of CompAir compressed air dryers are in use today across the world. They offer an excellent return on investment, updating your compressed air equipment will offer a payback a lot quicker than you may think, since these dryers offer a step change on energy savings which can be made.

These oil-free air compressor models contain absolutely no oil anywhere in the compressor and have been certified ISO 8573-1 Class Zero (2010) and silicone free.

Product Details:

Ultima™ is CompAir's groundbreaking oil-free PureAir screw compressor with a unique design. It is a brand new compressor range and it utilises a low pressure and high pressure dry screw airend. Each airend is individually driven by a variable speed, permanent magnet synchronous motor, offering exceptional levels of efficiency versus traditional oil-free technology.

CompAir is always improving the best products to be even better and more cutting edge. 

Product Details:

The scroll compressor has set a new standard in compressed air delivery. Not only does this scroll compressor series meet industry standards, but this technology reduces the costs of ownership because there is no need for oil filter replacements, oil condensate treatment and energy to combat the pressure loss caused by filtration. It is 100% oil and silicone contaminant free.

•    Premium 100% Certified Class 0 Oil & Silicone-Free Rotary Scroll Compressors
•    Reduced cost of ownership – no oil filter, no condensate treatment, no filters
•    Maximum flexibility from modular design & low maintenance due to fewer moving parts

Product Details:

What it is:

• Class Zero Oil FREE Rotary Screw Compressor
• Nominal Power from 37-150 kW
• Capacity of up to 25.9 m³/min (@ 7 bar g)
• Complementing the established 160 to 315 kW model range
• Fixed Speed and Variable Speed (RS) Models
• Air-cooled
• Numerous Further Options

Desiccant dryers work on the principle of moisture always migrating to the driest medium possible. Therefore, water vapour is removed from compressed air by passing it over an adsorbent desiccant material. In the above shown CompAir air treatment product family image, the desiccant dryer is shown in the centre by the twin towers & these types of air dryers can cater for larger airflow volumes. The full range of desiccant dryers is shown below.

As the air contacts the adsorbent material, water vapour transfers from the wet air to the dry desiccant, however, adsorbent materials have a fixed adsorption capacity and once this capacity is reached, they must be regenerated or replaced. 

Therefore, to provide a continuous supply of clean, dry compressed air, adsorbent dryers utilise two chambers of desiccant material and at any one time, whilst one chamber is on-line, drying the incoming compressed air, the other is either off-line, being regenerated or is re-pressurised, ready to come on-line.

All desiccant dryers remove water in this manner. The energy consumed by a desiccant dryer can be directly attributed to the method used to regenerate the adsorbent material. CompAir offer a comprehensive range using the latest technology to provide an energy efficient solution at the lowest life cycle costs. Our complete dryer range is produced in-house so the same quality, performance and efficiency standards delivered by our compressor ranges can now be enjoyed from the air treatment range, including the below advantages:

• Robust and reliable industry-proven design
• Suitable for all industries and applications - some desiccant dryer regeneration methods prevent their use in certain industries/applications
• Lower capital investment and reduced complexity compared to other dryer regeneration methods
• Lower maintenance costs in comparison to other dryer regeneration methods
• No heat, heaters, or heat-related issues
