Clean-Output Oil-Free Air Compressor

The Oil-free Water Lubricated Screw Air Compressor represents a remarkable innovation in air compression technology. Distinguished by its water - lubricated system, it completely eradicates the necessity for oil during the compression process, guaranteeing a 100% oil - free and clean air output.
This compressor is equipped with a pair of precisely designed helical rotors. As they rotate, water is injected into the compression chamber, serving as both a lubricant and a coolant. This dual - function of water not only ensures smooth operation of the rotors but also effectively controls the temperature rise during compression, enhancing the overall efficiency of the compressor.
One of its most significant advantages is its suitability for applications with stringent air purity requirements. Industries such as food and beverage, pharmaceuticals, and electronics can rely on this compressor to provide contamination - free air, ensuring product quality and safety. Additionally, the water - lubricated system results in lower maintenance costs, as there is no need to replace oil filters or deal with oil - related issues. With its high - efficiency operation, low - noise performance, and environmental - friendliness, the Oil-free Water Lubricated Screw Air Compressor is an excellent choice for modern industrial needs.

Working Principles


The compressor operates through a three-stage process to produce clean, oil-free air:

Intake Phase: Ambient air is drawn into the system through a high-efficiency air filter, which removes dust, debris, and other particles to protect internal components.

Compression Phase: Filtered air enters the compression section, where a pair of precision-machined helical rotors rotate to reduce air volume and increase pressure. During this stage, water is injected into the compression chamber—acting as a lubricant to minimize rotor friction and a coolant to absorb heat generated by compression, preventing overheating.

Exhaust Phase: The compressed air (now fully oil-free) is discharged through the exhaust section for use in downstream processes. The used water is either recycled (via a built-in treatment system) or safely disposed of, with no oil waste produced.

Characteristic Advantages


The compressor stands out with several competitive advantages:

Low Maintenance Costs: It eliminates the need for oil changes, oil filters, and oil-gas separators—cutting annual maintenance expenses to a fraction of traditional oil-lubricated compressors.

High Energy Efficiency: Its volumetric efficiency outperforms single-stage dry screw compressors by a significant margin, reducing electricity use and operational costs over time.

Environmental Friendliness: No waste oil is produced, and discharged water requires minimal treatment to meet environmental standards, aligning with sustainable manufacturing goals.

Stable Performance: The low-load rotor design reduces wear and tear, extending component life and ensuring reliable operation even in continuous 24/7 production cycles.



Applications


The QuietTech Water-Lubricated Oil-Free Compressor is tailored for industries demanding ultra-clean air:

Pharmaceutical Industry: Used for drug fermentation, capsule filling, and injection manufacturing, where oil contamination could render products unsafe or non-compliant.

Electronics Industry: Provides ultra-clean air for semiconductor lithography and circuit board welding, preventing oil-induced defects in sensitive components.

Food & Beverage Industry: Supports baking, filling, and packaging processes—ensuring no oil contaminates food products or violates hygiene regulations.

Medical Industry: Powers hospital oxygen supply systems, ventilators, and dental equipment, where oil-free air is critical for patient safety.

Textile Industry: Used in air-jet weaving and fiber processing, preventing oil stains on fabrics and maintaining product quality.



FAQ


Is the lubricating water reusable?

Yes, the compressor includes a water recycling system that filters and treats used lubricating water, minimizing consumption. Only a small amount of make-up water is needed to replace evaporation or minor losses, reducing water waste.


How quiet is the compressor compared to traditional models?

The QuietTech Water-Lubricated Oil-Free Compressor is significantly quieter. Its water-lubricated rotors and sound-dampening design reduce noise levels far below oil-lubricated compressors, making it suitable for indoor facilities where noise compliance is required.


Does it require specialized water treatment?

The compressor uses standard industrial water (with minimal impurities) for lubrication. The built-in recycling system filters out debris, so no specialized treatment is needed—though using softened water in hard-water areas can help prevent mineral buildup.



The QuietTech Water-Lubricated Oil-Free Compressor delivers three key functional benefits:


100% Oil-Free Air Output: Its water-lubricated design ensures no oil enters the compression chamber, meeting the strictest purity standards for industries like pharmaceuticals and semiconductors.

Temperature Regulation: The water injection system maintains optimal operating temperatures, preventing rotor damage from overheating and ensuring consistent compression efficiency.

Low-Noise Operation: The water-lubricated rotors reduce friction and vibration, while sound-dampening components further lower noise levels—making it suitable for indoor facilities where noise pollution is a concern.
