Reliable Compressed Air Quality for Electrical & Electronics Operations – Prevent Downtime, Ensure Efficiency
Uncontrolled humidity and oil aerosols in compressed air lead to corrosion, faulty instrument air, and product defects. Delair’s engineered & highly efficient refrigeration and adsorption Air dryers—paired with precision filtration—deliver clean and dry air that protects sensitive assemblies, instruments, and test rigs.
Why Dry, Clean Air Matters
Electrical and electronics manufacturing depends on compressed air for pneumatic valves operations, pick-and-place systems, PCB cleaning, blow-off, coating, and testing. However, ambient humidity and compressor carryover introduce moisture, oil aerosols, and particles that silently degrade quality. Effects range from oxidation on contacts and busbars to lens fogging, solderability issues, insulation tracking, and inconsistent machine behavior. The result is higher reject rates, rework, and unplanned downtime.
Challenges in the Electrical & Electronics Industry
Untreated compressed air is a hidden cost center in electrical and electronics (E&E) operations. Moisture condenses in lines and tools, causing corrosion of valves, cylinders, fixtures, and connectors. Oil aerosols foul instruments and contaminate surfaces prior to soldering, conformal coating, or painting. Particulate matter accelerates tool wear and compromises metrology, while dew-point drift reduces mean time between failures (MTBF) for actuators and relays.
Common problems caused by poor air quality:
- Corrosion of busbars, terminals, connector pins, and pneumatic components
- Condensation inside panels leads to insulation tracking/flashover risk
- PCB defects: poor adhesion, delamination risk, flux entrapment, coating pinholes
- Lens/mirror fogging in optical inspection and exposure equipment
- Sticking/erratic Pneumatic Valves Operations in handling and assembly lines
- Higher reject rates and rework; line slowdowns and unplanned stoppages
- Clogged nozzles and premature filter/desiccant failures increasing maintenance cost
In humid climates and on long outdoor runs, instrumentation air is especially vulnerable: even small dew-point rises can cause water to drop out in low points, creating corrosion, valve sticking, and spurious sensor behavior that inflate OPEX and jeopardize delivery schedules.
Applications That Require Compressed Air Dryers Alongside Compressors
Wherever a compressor is specified in E&E manufacturing, a dryer should be specified alongside it to prevent liquid water formation and oil carryover. Key applications include:
Instrumentation Air for Control and Automation
Pneumatic logic, I/P converters, positioners, and small actuators require a consistently low pressure dew point. Dryers prevent condensation in tubing, avoid rust, and keep response times stable across shifts and seasons.
Pneumatic Valves Operations in Assembly and Handling
Pick-and-place, conveyors, grippers, and indexing systems rely on clean, dry air to avoid sticking spools, clogged mufflers, and sluggish cylinders that create micro-stoppages and mis-picks.
PCB Assembly: Blow-off, Cleaning and Conformal Coating
Moisture and oil aerosols can cause solderability issues, ionic contamination, coating fisheyes, and pinholes. Dryers ensure consistent surface prep and coating outcomes.
Panel and Switchgear Manufacturing
Dry air protects contact surfaces, prevents insulation tracking, and keeps tools/gauges reliable during enclosure fabrication, painting/powder coating, and final testing.
Cable and Conductor Plants
Extrusion support air, post-wash drying, and leak/pressure tests demand stable dew point to avoid moisture entrapment and test variability.
