Where air quality matters
- Pneumatic handling and automation on production lines
- Blow-off and cleaning of parts and surfaces
- Air for process equipment supplied by tool makers, which often states its own air-quality requirement
- Vacuum handling, where fitted
Confirm the required quality with the equipment makers and the plant’s own quality team. The usual approach is oil-free compression or well-controlled oil-injected compression with proper filtration, plus drying. See what oil-free means, electronics and semiconductor air and battery manufacturing air.
Temporary and rental air
Rental air is often needed in this sector while permanent plant is being built or modified:
| Situation | What the rental unit must do |
|---|---|
| Commissioning before permanent compressors are ready | Supply stable pressure with the specified air quality for the equipment under test |
| Planned shutdown or retrofit of the main plant | Keep critical lines running; see planned shutdowns |
| Breakdown or capacity shortfall | Stand-in supply while repairs or expansion proceed; see compressor breakdown |
| Site without grid power for the temporary supply | Diesel-driven unit with the required air treatment; see diesel or electric |
Oil-free air from a diesel-driven rental needs an oil-free air end or a treated package, with tested downstream filtration and drying. See oil-free rental air and air-treatment trains.
What to tell us
- Required flow and pressure, and the equipment it serves
- The air-quality requirement and how it is verified
- Duration of hire and start date
- Site access, power and fuel arrangements
- Connection point and piping size
Send these to Reddy Compressors and we will propose the unit, the treatment and the delivery plan.
Field guide
Compressed air in solar cell and module plants
Solar manufacturing uses compressed air throughout the line: driving pneumatic handling, vacuum generators and cylinders, blowing and cleaning, and in some processes coming close to the product. Air quality, pressure stability and reliability all matter, because a stoppage or contamination can scrap expensive work in progress.
Typical uses
| Area | Air use | What matters most |
|---|---|---|
| Cell handling and automation | Cylinders, grippers, vacuum ejectors | Stable pressure, dry and oil-free air |
| Stringing and layup | Pneumatic tooling, positioning | Clean air to protect valves and product |
| Lamination | Press operation and vacuum support | Reliability; a stop mid-cycle scraps modules |
| Framing and junction box | Presses, dispensing, tools | Adequate flow at peak |
| Cleaning and blow-off | Air knives, nozzles | Efficient nozzles; often the largest single user |
Air quality
Where air touches cells, glass or encapsulant, oil and particles can cause defects. Plants commonly specify oil-free compressors or oil-injected compressors with high-efficiency coalescing and activated carbon filtration, plus dryers to a low pressure dew point. The required purity should be written as an ISO 8573-1 class for particles, water and oil, and checked at the point of use, not just at the compressor.
Reliability
- Size the compressor station with a standby machine, so one failure does not stop production.
- Provide receiver storage to ride through a compressor trip or a large blow-off.
- Monitor dew point and pressure, with alarms to maintenance.
- Plan maintenance in line with production shutdowns.
Energy
Blow-off and vacuum ejectors can consume a large share of the plant's air. Efficient nozzles, timers that blow only when product is present, and correct pressure settings reduce demand. Large continuous loads may justify a variable-speed compressor or heat recovery.
