Key Technical Specifications

Applications & Industries

The HC280 oilless air pump is engineered specifically for sectors where air purity and continuous operation are non-negotiable. In the realm of medical devices, this pump serves as a critical component for ventilators, dialysis machines, and central vacuum systems in clinics. The ability to maintain an air flow rate of up to 25L/min at a steady 700Kpa ensures that pneumatic medical tools and life-support systems receive the exact pressure required without the risk of oil mist entering patient airways or sensitive internal sensors. Its low noise output of ≤63dB(A) to ≤67dB(A) ensures quiet operation in patient care environments and laboratories, adhering to strict occupational noise regulations.

For industrial automation and food packaging, the HC280 provides a dependable pneumatic source for pick-and-place robots, vacuum sealing machines, and automated sorting lines. Food packaging facilities require strict adherence to hygiene standards; utilizing an oil-free pump prevents any potential contamination of consumables during the nitrogen flushing or vacuum sealing processes. The 24-hour continuous duty cycle and 10,000 to 70,000-hour lifespan mean that high-volume production lines can operate around the clock without scheduled maintenance shutdowns for lubrication. This continuous reliability directly translates to higher overall equipment effectiveness (OEE) and reduced total cost of ownership for facility managers.

Additionally, manufacturers of laboratory instruments rely on the HC280 for gas chromatography, mass spectrometry, and cleanroom air sampling equipment. The compact installation size of 147×83mm and a net weight of 6.8 kg allow OEM designers to integrate the pump directly into tight equipment housings without requiring extensive structural modifications. With a motor insulation class of F and thermal protection set at 145±5℃, the pump safely manages its own heat generation during prolonged analytical testing cycles, ensuring precise, repeatable results in fluctuating ambient temperatures from -5 to 40℃. The dual voltage options allow instrument manufacturers to standardize their internal pneumatic designs while shipping to different global regions.

Certifications & Compliance

Procurement engineers and OEM buyers require strict quality assurance and regulatory compliance to mitigate supply chain risks. The HC280 oilless air pump is manufactured in an ISO 9001 certified facility, ensuring that every unit rolling off the production line adheres to strict quality management principles. This guarantees consistent manufacturing tolerances, predictable performance across large batch orders, and a commitment to continuous product improvement for industrial buyers.

Furthermore, the HC280 carries CE and RoHS certifications. The CE mark indicates full compliance with European health, safety, and environmental protection standards, granting immediate market access for OEMs exporting equipment to the European Economic Area. RoHS compliance ensures that the pump is manufactured without hazardous materials such as lead, mercury, or cadmium. This is critical for manufacturers of medical devices and food packaging machinery who must meet stringent environmental directives and ensure the end-of-life recyclability of their products globally.

Frequently Asked Questions

What are the electrical requirements and thermal limits of the HC280?

The HC280 is available in two configurations to suit regional power grids: the HC280A-20/7 operates on 220V/50Hz/1 drawing ≤340W and functioning at 1400rpm, while the HC280B-25/7 requires 110V/60Hz/1 drawing ≤370W and functioning at 1700rpm. Both models feature a Class F motor insulation rating and include built-in thermal protection that automatically triggers at 145±5℃ to prevent damage from overheating. The pump functions safely in ambient air temperatures between -5 and 40℃.

Is the HC280 oilless air pump suitable for laboratory instruments requiring quiet operation?

Yes, the HC280 is highly suitable for laboratory environments. It operates at low noise levels, with the 220V model producing ≤63dB(A) and the 110V model producing ≤67dB(A). Combined with its 100% oil-free output, it prevents both acoustic disruption and chemical contamination in sensitive analytical and diagnostic settings.
