Oil-free Piston Air Compressor For Bus

 

Oil-free piston air compressor

 

Are you seeking a compressed air solution that delivers oil-free purity, environmental friendliness, and stable operation for your critical industrial processes? Our Oil-free Piston Air Compressor is tailored to meet the rigorous demands of global high-purity air applications, empowering industries worldwide with clean, efficient, and low-maintenance compressed air support.

 

An oil-free reciprocating air compressor is an air compression device that uses the reciprocating motion of a piston to compress air without using lubricating oil inside the compression chamber. Its core advantage is the production of clean compressed air free of oil mist, making it widely applicable in scenarios requiring high air purity.

 

Working Principle: Its working process is basically the same as a traditional oil-lubricated reciprocating air compressor, consisting of three strokes: intake, compression, and exhaust.

 

Intake Stroke: The piston moves downwards, the pressure inside the cylinder decreases, the intake valve opens, and outside air is drawn into the cylinder.

 

Compression Stroke: The piston moves upwards, the cylinder volume decreases, the drawn-in air is compressed, and the pressure increases.

Exhaust Stroke: When the pressure inside the cylinder reaches the set value, the exhaust valve opens, and the compressed air is delivered to the air tank or directly supplied to the user.

The key difference from oil-lubricated models is that the piston rings, cylinder walls, and other key friction components of the oil-free reciprocating air compressor use self-lubricating materials (such as PTFE, graphite, ceramics, etc.), eliminating the need for lubricating oil for lubrication and sealing, thus preventing oil contamination of the compressed air from the source.

 

Our Oil-free Piston Air Compressor is widely recognized and adopted in global high-purity air demand scenarios:

- Medical & Healthcare: Dental equipment, ventilators, surgical instrument pneumatic drives, hospital sterile processing centers (compliant with medical device GMP standards).

- Food & Beverage: Food packaging, filling equipment, beverage bottling lines, bakery production (avoids oil contamination, meets FDA food contact requirements).

- Electronics & Semiconductor: Electronic component dust removal, PCB board processing, semiconductor manufacturing (prevents oil mist from causing short circuits or component damage).

- Pharmaceuticals: Pharmaceutical production pneumatic conveying, drug packaging equipment, laboratory precision instruments (complies with pharmaceutical GMP certification).

- Laboratories & Research: University laboratories, industrial research institutions, precision instrument testing (ensures the accuracy and reliability of experimental data).

- Textile & Garment: Textile machinery pneumatic components, fabric finishing processes (avoids oil stains on fabrics, ensuring product quality).

 

A. Compact structure

The permanent magnet motor is integrated with the cylinder frame, so the whole machine is small in size and light in weight, which greatly reduces the appearance size.

B. Low noise

The noise of the piston air compressor mainly comes from the air intake link. Through the optimized design of the cylinder head, cylinder tube and air intake system, the noise is reduced to below 72db, which is more in line with environmental protection requirements.

C. Lightweight design

The aluminum main engine weighs only 52 kg, which reduces the weight of the entire vehicle and saves energy for customers.

D. High adaptability

It has excellent adaptability and reliability to the ambient temperature, and can adapt to the working environment of -45℃~+65℃.

E. Super coating

The inner wall of the cylinder adopts super coating, which has good air tightness and little wear, which can prolong the service life of the whole machine.

F. Longer life

The machine adopts imported high-temperature bearings to ensure that the grease will not be lost and the life of the whole machine.

G. Low cost maintenance fee

The main engine has fewer parts, fewer wearing parts and low maintenance costs. At the same time, it does not require lubricating oil, saves oil consumption, does not need frequent maintenance, and saves money and worry.

A. No need to add lubricating oil

No need to add lubricating oil, the exhaust gas does not contain oil, which eliminates the adverse consequences of oily gas on the production process, and will not pollute the user's end product

B. No lubricating oil

Does not contain lubricating oil, will not produce the adverse effects of lubricating oil solidification in low-temperature engineering and lubricating oil emulsification in high-temperature and humid environments

C. Gas without oil

The gas does not carry oil, which reduces and eliminates the possibility of oil deposits on the wall of the heat exchanger, improves the heat exchange efficiency and reduces the resistance loss of the gas.
