Our high-performance oil-free compressor pumps for medical devices meet the strict demands of global respiratory therapies. Zhejiang Ouhang Electromechanical Co., Ltd. (OH) is a professional manufacturer of precision rocking piston compressors and vacuum pumps. We focus exclusively on supplying premium internal components to original equipment manufacturers (OEMs). We do not produce fully assembled retail consumer devices.
With over 12 years of manufacturing experience, we deliver highly durable components. Our dedicated R&D team brings more than 25 years of technical expertise to every project. We design reliable core solutions that serve as the dependable heart of modern healthcare technologies.
Our medical-grade oilless air compressors ensure easy integration, high efficiency, and extreme safety. We prioritize clean, contamination-free airflow and robust structural elements. This ensures our pumps meet the high standards of critical care. Are you building compact mobile systems or hospital-grade respiratory networks? Our technical team collaborates with your engineers at every step. We support you from initial pump selection and prototyping through mass production.
To assist equipment engineers and procurement managers, we offer a diverse catalog of rocking piston bare pumps. The specifications below showcase our popular models. They illustrate how we balance power consumption, flow rate outputs, and physical dimensions. This variety perfectly suits diverse clinical and battery-driven applications.
| Model | Type / Power Source | Nominal Power (W) | Flow Rate (L/min) | Primary Medical Application |
|---|---|---|---|---|
| OH-30Z | Compact DC | 30W - 50W | 15 - 25 L/min | Portable Oxygen Concentrators, Mobile Therapy |
| OH-50Z | Compact DC | 50W - 80W | 25 - 35 L/min | Portable Clinical Respiratory Devices |
| OH-280D | Standard AC | 280W | 70 - 75 L/min | Clinical Oxygen Concentrators (5L/10L) |
| OH-280NZ | Silent AC | 280W | 75 L/min | Bedside Medical Equipment, Hospital Ventilators |
| OH-280N-MAX | Heavy-Duty AC | 350W | 80 - 90 L/min | Multi-Bed Oxygen Systems, Dental Stations |
| OH-590N-MAX | High-Flow AC | 590W | 110 - 120 L/min | Clinical Aspiration, High-Flow Respiratory Therapy |
The OH-30Z and OH-50Z series are highly optimized, space-saving DC-powered bare pumps. They are designed for portable clinical systems requiring low weight and high energy efficiency. These compact units operate exceptionally well on battery power. This makes them ideal for mobile oxygenation therapies and portable equipment. We engineer these micro-compressors to minimize structural heat generation. They deliver a stable, clean airflow without draining battery resources or adding excess weight.
Positioned as standard workhorses for healthcare hardware, the OH-280D and OH-280NZ series are highly reliable. They deliver an impressive nominal flow rate of up to 75 L/min at low noise levels (≤51dB). These 280W-class rocking piston pumps provide the consistent pressure output required for medical environments. Advanced internal sound-dampening structures minimize physical vibration. This ensures bedside devices can operate in patient wards without disrupting rest or clinical procedures.
For installations requiring superior power, the OH-280N-MAX and OH-590N-MAX series provide high-volume rocking piston capabilities. Built with high-horsepower AC motors, these heavy-duty units maintain peak performance under elevated pressures. They excel during long operating cycles. These models are ideal for multi-bed clinical oxygen networks and laboratory aeration systems. They also support larger dental networks where continuous load endurance is mandatory.
When selecting internal components for clinical technologies, reliability, safety, and acoustic comfort are non-negotiable. Our specialized manufacturing processes address common mechanical failure points. This results in unmatched lifecycle value and superior performance for your equipment.
The defining strength of our product lineup is a robust design architecture. Our pumps are capable of up to 8,000 hours of continuous runtime. Standard commercial pumps often overheat or lose pressure during prolonged cycles. In contrast, our medical-grade units easily withstand 24/7 operations. This exceptional durability drastically reduces equipment downtime. It saves clinical facilities from frequent, costly maintenance while maintaining vital oxygenation support.
Clinical settings demand quiet environments to aid in patient recovery. Our engineering team achieves ultra-low noise levels down to ≤51dB. We employ precision dynamic balancing on all rotating elements and use high-insulation cylinder designs. This approach significantly dampens mechanical noise and structural vibration. Device OEMs can then easily house our bare pumps in lightweight plastic enclosures without excessive acoustic insulation.
Quality begins with core materials. We use 100% pure copper wire coils in all our motors. This ensures excellent heat dissipation, higher electrical efficiency, and a longer lifecycle than aluminum alternatives. Furthermore, the piston rings are manufactured from high-grade, heat-resistant PTFE compounds. This allows the compressor to function smoothly without any lubrication. As a result, it maintains 100% dry and clean air delivery.
Clean air delivery is vital across a wide range of healthcare sectors. We integrate our oilless rocking piston pumps into diverse technical environments. By focusing on critical applications, we ensure each pump perfectly matches target airflow and control parameters.
A critical application for our bare pumps is within medical-grade oxygen concentrators. They deliver the exact, stable pressure required to push ambient air through molecular sieve beds. This ensures highly effective nitrogen absorption. Are you developing a compact 3L personal device or a 10L clinical stationary system? Our internal pumps maintain the tight pressure tolerances needed to sustain high-purity medical oxygen flow.
For ventilators and respiratory support systems, air purity directly impacts patient safety. Our pumps provide extremely clean, dry, and particulate-free air. With precise dynamic control, they effectively minimize micro-fluctuations. These features enable fine-tuned respiratory delivery. They ensure stable volume and pressure parameters that adapt perfectly to patient breathing cycles.
Beyond respiratory therapies, our reliable bare pumps serve adjacent professional markets. They provide steady vacuum or positive pressure for dental treatment chairs. They are also used in laboratory aspiration platforms and advanced aesthetic skin-treatment systems. Their versatile pressure-holding capabilities make them an ideal component across multiple healthcare disciplines.
