Mobile air compressors are portable, towable compressors particularly useful for applications that suit the construction and roading
industry! You'll often see a mobile compressor being used for sandblasting, irrigation blow-outs, and for quarrying tools such as pneumatic
block cutters and rock drills.
So what are Mobile compressors?
When you think of an air compressor, most people think about piston compressors or compressors that are stationary. Mobile compressors are
portable, easily attached to vehicles or trucks for towing to site, and are almost always diesel powered! They range from very small, to
very large and can be offered with electric motors, or are diesel engine powered oil-injected screw compressors.
Today, mobile compressors must demonstrate high overall operational flexibility to serve a range of applications in different environments
based on ambient temperatures, humidity levels, working pressures, altitudes and load cycle profiles. Other requirements relative to mobile
compressors include high operating reliability, good service characteristics, small environmental impact resulting from low noise levels and
regulated exhaust emission levels, compact dimensions and a low total weight.
What are these towable compressors used for?
Mobile compressors initially were used on construction sites and for off-road drilling. You'll see them now being used in many more
applications and processes: road repair, pipeline work, rock reinforcement, sandblasting, salvaging operations, etc. Generally, mobile
compressors are packaged as standalone compressed air plants with optional, integrated air treatment equipment on-board (aftercooler, water
separator, fine filters, reheater, lubricator, etc.) as well as optional auxiliary equipment (5 to 10 KVA electric power generator
230V/400V, cold start aids, anti-theft devices, spillage-free chassis etc). There are mobile, diesel powered electric power generators built
in similar enclosures as mobile compressors for larger power requirements.
Are mobile compressors noisy?
These days diesel-powered compressors have considerably lower noise levels. These machines can therefore be used without negatively
impacting populated areas and areas near hospitals, etc. The silencing enclosure is generally a single-wall steel construction, although
double-wall steel and even durable polyethylene enclosures have recently been introduced, containing special baffling and substantial
amounts of sound absorbing foam.
In the last 20 years fuel economy has improved substantially by introducing very efficient screw compressor elements and efficient
packaging. This has been especially valuable for water well drilling, which is a task that requires the compressor to work intensively over a
long period of time. Moreover, modern compressors can be equipped with fuel economy optimizing hardware and software that is far superior to
the conventional pneumatic engine/compressor control systems.
Since the introduction of specific exhaust emission legislation in 1997 in the United States, Europe and elsewhere, diesel engines that
comply with latest exhaust gas emission requirements are being chosen more often.

Reliability and Efficiency
With Ash Air compressors, you can count on reliability and high performance for even the most demanding applications. We focus our
efforts on the following:
Air is always contaminated with solid particles such as dust, sand, soot, salt crystals and water as it leaves the compressor. An effective
compressed air treatment system lowers the dew point of the air and takes out the elements that may harm equipment downstream of the
compressor and dryer
The ambient temperature in an air compressor’s environment can greatly affect your air compressor’s performance. All air compressors will
generate some amount of water, but depending on inlet air conditions some can produce large amounts of water.
