Clean Dry Air for Semiconductor Manufacturing
Clean Air. Dry Air. Reliable Production.
Semiconductor manufacturing requires compressed air with strict control of oil, moisture and particulate contamination. A properly designed Clean Dry Air (CDA) system helps protect sensitive processes and production equipment while maintaining a stable air supply.
01 — Oil Contamination Control
Reduce the risk of oil aerosols, vapors and hydrocarbons entering sensitive air systems. Oil-free compression provides a clean foundation for semiconductor CDA systems, while final air quality should be specified and verified at the point of use.
02 — Ultra-Dry Air
Adsorption drying helps maintain the required pressure dew point and prevent moisture condensation across the distribution network. Dew point targets can be engineered around your process requirements, site conditions and critical point-of-use applications.
03 — Particle Protection
Multi-stage filtration helps control airborne particles, pipe-scale and other contaminants before air reaches cleanroom tools, pneumatic controls and sensitive process equipment. Point-of-use filtration adds protection where air purity is most critical.
Complete CDA System
Oil-Free Compressor → Pre-Filter → Adsorption Dryer → Post-Filter → PTFE Membrane Filter → Process
By combining oil-free compression, moisture removal and multi-stage filtration, Sollant provides customized CDA solutions designed around the required air quality, pressure, flow rate and application conditions of semiconductor and electronics manufacturing facilities.

Typical Customer Applications
Case Study: On-site Ultra-pure Nitrogen Generation for Semiconductor Wafer Manufacturing
A semiconductor wafer manufacturing plant in Singapore required nitrogen for critical processes such as reaction chamber purging, wafer transfer, and lithography environment displacement. The specifications demanded a pressure dew point of -40°C to -70°C and an oil content of ≤0.01 ppm, meeting standards for ultra-pure gas and ISO 8573-1 Class 0. The facility previously relied on purchased liquid nitrogen, resulting in high costs and supply vulnerability due to logistics.
Solution:
- Adsorption dryer: Controls the pressure dew point within the -40°C to -70°C range.
- Precision filters (Grade A/H): Grade A captures particulates, while Grade H (activated carbon) removes oil vapor, ensuring oil content remains ≤0.01 ppm.
- PSA nitrogen generator: Produces high-purity nitrogen (≥99.999%).
Results: The point-of-use pressure dew point stabilized between -55°C and -65°C, and oil content consistently remained below 0.01 ppm, meeting ultra-pure gas requirements. Switching from purchased liquid nitrogen reduced gas costs and improved supply stability; no wafer defects caused by gas quality issues were observed.

Semiconductor Compressed Air FAQ
Semiconductor manufacturing primarily uses oil-free air compressors, including oil-free screw (dry or water-lubricated), oil-free scroll, and oil-free centrifugal compressors. These machines deliver ISO 8573-1 Class 0 pure air with zero risk of oil contamination. Oil-injected compressors are not acceptable for process or cleanroom applications because even microscopic oil aerosols can damage wafers and reduce yield. Sollant offers dedicated models such as the SLTOF-75VW water-lubricated screw, SLTOF-11S oil-free scroll, SLTOF-90FD dry variable-speed screw, and oil-free centrifugal compressors specifically engineered for semiconductor environments.
Any trace of oil (vapor, aerosol, or liquid) can contaminate photoresist, dielectric films, or metal interconnects, causing irreversible defects, lower yield, and costly scrap. Semiconductor processes operate under the strictest cleanliness standards. Oil-free compressors eliminate contamination at the source rather than relying on downstream filters that can fail. This is why fabs mandate true oil-free technology certified to ISO 8573-1 Class 0.
CDA stands for Clean Dry Air. It refers to ultra-pure compressed air that meets the highest standards for particles, moisture, and oil content. CDA is used for wafer handling, cooling, pneumatic actuation, cleanroom positive pressure control, instrumentation, and as feed air for on-site nitrogen generation. A complete CDA system typically includes an oil-free compressor, adsorption dryer, precision filters, and stainless-steel piping to deliver consistent Class 0 quality air 24/7.
ISO 8573-1 Class 0 is the highest air purity classification. It means the compressed air contains no detectable oil in any form (liquid, aerosol, or vapor) beyond the strict limits set by the manufacturer and verified by independent testing (typically ≤ 0.01 mg/m³ or lower). Class 0 is stricter than Class 1 and is the mandatory baseline for semiconductor process air, cleanrooms, and critical instrumentation. True Class 0 performance is achieved only with certified oil-free compressors, not by filtering oil-injected machines.
Most semiconductor applications require a pressure dew point of -40 °C or lower. Critical processes such as advanced lithography or ultra-sensitive areas often demand -70 °C. Moisture can cause corrosion, particle adhesion, or process defects. Sollant pairs its oil-free compressors with modular or zero-air-consumption heat-of-compression adsorption dryers and A/H-grade precision filters to reliably achieve these ultra-low dew points while meeting oil content ≤ 0.01 ppm.
It depends on your flow and pressure requirements:
Oil-free screw compressors (water-lubricated or dry VFD) are ideal for medium flow rates, flexible load profiles, and energy-efficient part-load operation. They are widely used for process air and cleanroom supply.
Oil-free centrifugal compressors are preferred for large, stable base-load demand where continuous high-volume air is needed with excellent efficiency at full load.
Sollant supplies both technologies and can recommend the optimal combination based on your fab’s air demand curve, pressure levels, and redundancy needs.
Yes. Sollant delivers fully integrated Clean Dry Air (CDA) solutions that include:
- Oil-free compressors (screw, scroll, or centrifugal)
- Adsorption dryers (modular or zero-air-consumption heat-of-compression types)
- A/H-grade precision filters
- Nitrogen generators (dual-tower or combined systems)
- System design, controls, and stainless-steel piping recommendations
All components are engineered to work together to meet ISO 8573-1 Class 0, target dew points of -40 °C to -70 °C, and ultra-low oil and particle levels required by semiconductor fabs.
Yes. With 22 years of export experience and an annual production capacity of 20,000 units, Sollant routinely customizes systems for semiconductor clients. Customization options include pressure (7–12.5 bar or higher), flow capacity, variable-speed drive configuration, skid-mounted or containerized packages, special materials for cleanroom compatibility, noise levels (down to ≤ 65 dB(A)), control integration, and complete CDA + nitrogen packages.
