Automotive & Garage

Though you might not realize it, dry compressed air affects each and every unit in Automotive industry.

Tyre Inflation

Compressed air used to inflate tyres.

Product Finishing

Compressed air vaporizes and propels paint through paint guns or robots onto clean metal surfaces such as car components and shells.

Air Operated Robots

Where reliability and repeatability are required Compressed air is used for the operation of robots.

Plasma Cutting and Welding

Compressed air is used in the process to assist the cutting or welding speed and reliability.

Air Tools

Air tools are preferred to electric tools as they are light and easy to handle.

Paint Shop Applications

Compressed air is the first choice as a safe medium to operate paint pumps in highly volatile environments.

Breathing Air

Air filtration is used to provide breathing quality air.

Use of Compressed Air in Automotive Industry

  • Tool Powering
  • Spray Painting
  • Pneumatic control and actuators
  • Forming
  • Powder Coating
  • Changing and filling tyres
  • Conveying
  • Stamping
  • Welding
  • Powder coating operation
  • Molding

Compressed Air Powered Pneumatic Tools

All pneumatic machines and tools are powered by compressed air. These compressed air comes out from compressor and through pipe lines it goes to various manufacturing units. This compressed air is further distributed to pneumatic machines and tools through pipe lines.

  • Pneumatic tools
  • Pneumatic air guns
  • Pneumatic nail gun
  • Pneumatic Launchers
  • Pressure switch
  • Compressed-air engine
  • Pressure regulator
  • Pneumatic motor
  • Pneumatic actuator
  • Gas-operated reloading
  • Pressure sensor
  • Pneumatic tyre
  • Electro-pneumatic action
  • Lego pneumatics
  • Tubular-pneumatic action
  • Pneumatic cylinder


A major problem in compressed air systems is the presence of water, dust particles, oil (oil particles are introduced by lubricated air compressors) and solid contaminants which can adversely affect air quality.

If the contaminated compressed air will be used through pneumatic tools and machines then there will be following effects :

  • Malfunctioning of pneumatic tools and machines
  • Sluggish and inconsistent operation of valves and cylinder
  • Corrosion in pipe lines, cylinder and other components
  • Increase in downtime
  • Increase in maintenance cost of pneumatic machines / tools / controls.
  • Freezing in exposed lines during cold weather.

During spray painting manually as well as by painting robots,  compressed  air mixes with paint before spray then all these pollutants found in compressed air lead to blisters in paint surfaces, water droplet marks in surface and low  quality shining in bumpers which leads to low quality finish. Moreover there will be rust / corrosion in painting robots. This leads to malfunctioning, high maintenance cost and decrease in durability of painting robots.

During the process of powder coating operation if there will be moisture in compressed air that there will be following problems:

  • Lump of powder in pipe lines, this may lead to uneven spray of powder.
  • Craters in the finish / surface
  • Porosity in the coating

The CompAir Solution

Remove  water, dust particles, oil (oils particles are introduced by lubricated air compressors) and solid contaminants from compressed air.

CompAir offers wide range of refrigeration dryer and adsorption dryers which removed water / moisture from compressed air.

Puriflair refrigeration dryers operate on the method of cooling the air to near freezing point to remove the moisture and reheating it to approximately 10°C below the incoming compressed air temperature at nominal conditions.

CompAir Adsorption Dryer

The dryers is based on the principle of heatless regeneration and the physical properties of ther desiccant to adsorb and desorb the water vapour, It uses pressure swing principle / purge air to regenerate the desiccant bed.

CompAir Filters

CompAir also offers Pre Filters and Oil Filters which removes dust particles, oil particles and other types of solid contaminated  present in dry air.
