In Manufacturing units almost all companies use compressed air for spray painting. Spray painting can be done by two methods:
- Manually – through electrostatic guns
- Automatic – through painting robots
A major problem in compressed air systems is the presence of water, dust particles, oil (oils particles are introduced by lubricated air compressors) and solid contaminants which can adversely affect air quality. When 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.
When spray painting is done through painting robots then contaminated compressed air causes low quality final finishing and rust / corrosion in painting robots. This leads to malfunctioning on pneumatic systems, high maintenance cost and decrease in durability of painting robots.
The shining quality of bumpers used to be increased by manually polishing them by cream.
General Recommendation
Remove water, dust particles, oil (oils particles are introduced by lubricated air compressors) and solid contaminants from compressed air.
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.
Filters
Delair also offers Pre Filters and Oil Filters which removes dust particles, oil particles and other types of solid contaminated present in dry air.
