Automobile Industry



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

Use of Compressed Air Dryer in Automobile 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 syatems used in automobile Industry

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 Delair Solution

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

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

Delair 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.


Delair 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.



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