A compact, oil‑free, high‑pressure gas booster with 1–3 kW adjustable power and 150 bar maximum outlet pressure, purpose‑built for laboratory and industrial high‑pressure gas supply applications.
Product Advantages
1. 100% Oil‑Free Purity
The compressor operates with absolutely no oil in the compression chamber. All friction parts (e.g., piston rings, guide rings) are made of self‑lubricating special materials. The output gas meets ISO 8573‑1 Class 0 oil‑free certification, completely eliminating the risk of oil contamination – critical for high‑pressure applications demanding strict gas purity.
2. Energy Efficiency & Lower Operating Costs
The booster starts from an already pre‑compressed gas source (3–4 bar) rather than from atmospheric pressure. This significantly reduces the compression ratio compared to a single‑stage compressor that compresses from 0 to 150 bar, resulting in much lower power consumption. The 1–3 kW power range further minimises energy use, delivering substantial long‑term savings on electricity costs.
3. High‑Pressure Output up to 150 bar
With a maximum discharge pressure of 150 bar, the unit meets the demands of diverse high‑pressure scenarios, including high‑pressure vessel filling, precision pressure testing, and specialised process gas delivery. The multi‑stage compression with inter‑stage cooling ensures stable, continuous operation even under extreme pressure conditions.
4. Compact & Flexible Integration
With small physical dimensions , the booster can be easily deployed on laboratory benches, beside production lines, or in other confined spaces. It connects directly to existing medium‑ or low‑pressure compressed air networks without requiring plant‑wide system modifications. The modular design supports capacity expansion as needs grow.
5. Low Noise Level – Suitable for Indoor Installation
Operating noise is typically below 75 dB(A), making the unit ideal for noise‑sensitive indoor environments such as laboratories, hospitals, and cleanrooms.
6. High Reliability & Low Maintenance
The slow‑speed, heavy‑duty design (typically 200–400 rpm) extends the service life of wearing parts while minimising vibration and noise. Compared to large‑scale high‑pressure systems, maintenance procedures are simpler, intervals are longer, and overall maintenance costs are significantly lower.

FAQ
FAQ1: What is the difference between a booster compressor and a standard compressor?
A: A booster compressor raises existing low‑pressure gas (e.g., 3–4 bar) to a higher pressure (e.g., 150 bar) with lower energy consumption, while a standard compressor compresses from atmospheric pressure and cannot directly reach such high pressures.
FAQ 2: Why choose an oil‑free booster compressor?
A: Oil‑free models have no lubricating oil in the compression chamber, and the output gas meets ISO 8573‑1 Class 0 standards, eliminating contamination risks. They are ideal for industries requiring high purity, such as medical, food, electronics, and laboratories.
FAQ 3: What are the inlet pressure and air source requirements?
A: The booster requires clean pre‑compressed gas at 3–4 bar. A precision filter upstream is recommended. It cannot draw air directly from the atmosphere; it must be installed downstream of an existing compressed air supply.
FAQ 4: What is the maintenance schedule and which parts need replacement?
A: Piston rings and guide rings should be inspected/replaced every 5,000–8,000 hours; valves should be checked every 2,500 hours, Intervals may vary based on operating conditions.
FAQ 5: Can this booster be used for oxygen or nitrogen?
A: Yes, it can handle air, nitrogen, oxygen, and other gases. For oxygen service, the entire unit must undergo strict degreasing, and all contacting components must be oil‑free.
