Towable Compressors - Compressed Air on the Go

Compressed air is needed for many applications, often in industrial plants and warehouses. However, there are many times when compressed air is needed on building sites or other remote locations. For applications like this, a towable compressor is an indispensable piece of equipment.


Small, compact and robust, towable air compressors are designed to deliver the same high quality of compressed air, on-the-go! Designed to meet the demanding conditions of a variety of terrains, towable compressors give you the freedom to benefit from a reliable source of compressed air, in any location.

Operating Principles

The C-Series of portable air compressors from CompAir utilises screw compression technology. The male and female rotors spin in opposite directions, trapping air in the space between them and forcing it to a higher pressure.


The rotors are powered by an environmentally friendly and energy-efficient diesel engine motor. The motors are equipped with a soft start-up mechanism to reduce stress on the engine, allowing it to reach the running temperature with the compressor unloaded.


Portable controllers with digital displays allow you to monitor your compressor operational data. The controller is equipped with quick and easy-to-use pressure settings and indication lamps which allow you to get the most out of your machine.

Emission Standards

It is important to ensure that your mobile air compressor fulfils the emission standards outlined in directive 97/68/EC against the emission of particulate pollutants from internal combustion engines in non-road mobile machinery. All diesel engines must conform to this standard to ensure that they are environmentally friendly and safe to use on busy working sites.


All towable compressors within the C-Series conform to this standard and are fitted with a Diesel Particle Filter (DPF). These help to control emissions by removing contaminating particles from the air by passing the exhaust gases through a flow filter that traps any polluting particles. The DPF will need regular cleaning to ensure the build-up of particle matter is removed.


Several of our models can be retrofitted with diesel particle filters in order to bring your existing compressor up to the current emission legislation standards.




Uses in industry

Running Pneumatic Machinery and Air Tools


The most common use of towable compressors is to power air tools or other pneumatic machinery. Air-driven tools are the industry standard across many industrial applications as they offer great energy savings and are powerful and reliable.


Road Building and Construction Jobs


Mobile air compressors are often used for general road building and construction jobs as users need to access the building sites quickly and easily. Diesel compressors are a great option for construction as you do not need to worry about connecting to the power grid for electricity.


Quarrying


Air compressors can provide power to drills that are used for quarrying and extracting stones or other materials. As expected, quarries often have rough terrain so the compressor must be sturdy, balanced and able to handle demanding ground conditions.


Restoration Work and Landscaping


Towable compressors are used in remote locations where landscaping and other restoration building work may be taking place.

Electric or Diesel


Electric powered towable compressors may be a cheaper initial investment but it means you must always rely on access to a power supply to use the equipment. This may pose a challenge in remote construction locations. Diesel-powered towable compressors are a versatile option and can often be fitted with integrated generators which can supply electricity to power lighting and electric tools on site. When choosing a diesel compressor, it is also important to consider emissions and safety standards.



Flow and Pressure


You should consider what type of applications your mobile compressor will be used for. As you will be solely relying on this compressor in an off-site location, it is important that it is powerful enough to serve your needs.



Weight, Size and Maneuverability


Weight and size are extremely important factors for towable compressors. The compressor you choose must be compact and light enough to be towed by your vehicle. If your towing vehicle is small, you may want to consider a lighter compressor.
Maneuverability is also another key factor. If you intend to tow your compressor over rough or uneven terrain, it must be sturdy enough to remain balanced but flexible enough to handle rough surfaces and roads.



Noise Level


Where you use your compressor will affect how low-noise your compressor will need to be. Some towable compressors are quiet by design, making them the perfect option for busy, urban areas.
