As a dedicated pneumatic component manufacturer, Zhejiang Ouhang Electromechanical Co., Ltd. delivers premium Oil-Free Compressor Pumps for critical OEM applications. Our compressor heads meet the stringent demands of medical, dental, laboratory, and aesthetic equipment. They provide high durability and completely clean compressed air. These pumps support up to 8,000 hours of continuous operation. They easily withstand heavy-duty cycles without any oil contamination risks.
System integration requires precise compatibility. Therefore, we offer flexible ordering policies and support small-batch trial orders. This allows OEMs to evaluate our fractional horsepower pumps for perfect mechanical and electrical alignment. Standard mass-production delivery is rapidly completed within 7 to 15 days. This keeps your assembly lines productive and uninterrupted. To discuss custom specifications, please contact our engineering team for an evaluation sample.
We supply a versatile lineup of standard oil-free compressor models. These seamlessly replace or upgrade industry-standard fractional-horsepower pumps. By matching standard industry footprints, our models help manufacturers optimize their supply chains. This eliminates the need to redesign existing chassis or mounting layouts. Featured series include the high-efficiency 30Z, 50Z, 70Z, 250E, 280D, 280N-MAX, 590N-MAX, and 280NZ.
| Model / Series | Power Output (W) | Flow Rate (L/min) | Max Pressure (bar) | Typical Application Alignment |
|---|---|---|---|---|
| 30Z / 50Z Series | 150W - 250W | 30 - 50 L/min | 3.5 - 4.0 bar | 3L - 5L Medical Oxygen Concentrators, Portable Medical Devices |
| 70Z / 250E Series | 300W - 400W | 70 - 90 L/min | 4.5 - 5.0 bar | Dental Delivery Systems, Standard Laboratory Filtration |
| 280D / 280NZ Series | 500W - 550W | 100 - 120 L/min | 7.0 - 8.0 bar | Multi-Chair Dental Units, Skin Care & Aesthetic Treatment Devices |
| 280N-MAX / 590N-MAX | 600W - 1100W | 150 - 240 L/min | 8.0 - 10.0 bar | Heavy-Duty Clinical Aesthetic Machines, Industrial Lab Systems |
Operating conditions differ greatly across industries. Each requires precise control over noise, vibration, footprint, and continuous pressure. We tailor our compressor heads to excel in these demanding environments, ensuring specialized reliability where it matters most.
Our medical-grade series is specifically engineered for continuous oxygen delivery systems. We calibrate these pumps for 5-liter and 6-liter clinical and home medical oxygen concentrators. They deliver a reliable oxygen supply using low-vibration engineering. This keeps noise levels below 45 dB for enhanced patient comfort. Furthermore, the units consistently maintain the clean, oil-less airflow critical for patient wellness.
Low-Noise Performance: Whisper-quiet operation enhances home care comfort and reduces patient stress.
Advanced Heat Dissipation: Built-in cooling structures comfortably support continuous 24/7 run cycles.
Wear-Resistant Pistons: High-performance polymer piston rings eliminate degradation over thousands of hours.
Air purity is paramount in dental clinics and aesthetic treatment rooms. Our oil-free compressor heads protect sensitive valves, dental handpieces, and micro-nozzles from contamination. Models like the 280D and 280NZ feature compact physical footprints. This allows them to fit effortlessly inside narrow aesthetics carts and integrated dental utility consoles.
Laboratory applications require unwavering vacuum stability and steady pressure cycles. Our dual-use fractional pump series provides highly responsive pressure control and vacuum capability. This is essential for scientific filtration, analytical instrumentation, and general lab automation. Engineered with durable materials, these pumps maintain constant flow rates during sensitive research trials.
