HC680 Oilless Air Pump | 610W, 60L/min@700Kpa, 24h Duty

HC680 Series — AC Oil-Free Air Compressor

Why Choose the HC680 Oilless AC Air Pump

Picture a homecare or clinical device where a compressor must run for hours in a quiet room — next to a patient, inside a laboratory, or beneath a treatment chair — and where even a trace of oil vapor can compromise sensitive valves and patient airways. In environments demanding quiet operation and absolute purity, relying on lubricated pneumatics introduces unacceptable risk. The HC680 oilless air pump guarantees a completely oil-free air supply while delivering a steady 60L/min at 700Kpa at a whisper-quiet ≤60dB(A) — eliminating contamination, lubrication maintenance and noise complaints in a single unit. With its twin-cylinder, pressure-parallel-flow head, the HC680 gives OEM buyers and technical managers a pneumatic core they can design around for years of service.

Key Features

• 100% Oil-Free Operation — eliminates oil-mist contamination entirely, making it safe for medical, laboratory, dental and food-processing integration where air purity is non-negotiable.
• Ultra-Quiet Performance — among the quietest in its class at ≤60dB(A) on the 220V model and ≤61dB(A) on the 110V model, ideal for patient-care rooms, laboratories and noise-sensitive indoor facilities.
• High-Output Twin-Cylinder Design — heads in pressure-parallel-flow configuration deliver a consistent 60L/min at 700Kpa, with free-air delivery of up to 125L/min for demanding peak loads.
• Energy-Efficient Motor — consumes only ≤610W at rated pressure on both voltage models, lowering electrical overhead for continuously operating equipment.
• Thermal Safety — integrated thermal protection activates at 145±5°C to prevent motor overheating during intensive operation.
• Global Voltage Flexibility — offered as HC680A-60/7 (220V/50Hz/1) and HC680B-60/7 (110V/60Hz/1), so OEMs can standardize one pneumatic platform across regional markets.
• Wide Operating Range — functions reliably in ambient air temperatures from -5°C to 40°C.

Applications & Industries

Medical & homecare focus — For medical and homecare devices, air purity and low noise are not preferences — they are requirements. The HC680 serves as a dependable pneumatic source for oxygen concentrators, CPAP and respiratory support systems, dental units and medical air systems, sustaining up to 60L/min at a steady 700Kpa so equipment receives the exact pressure it needs without any risk of oil mist reaching patients or internal sensors. Its ≤60dB(A) noise output keeps bedrooms, treatment rooms and laboratories comfortably quiet.

Industrial & food processing — In industrial automation and food and beverage processing, the HC680 provides a clean pneumatic source for actuators, vacuum and sealing stations and automated filling lines. Food and beverage facilities must keep compressed air free of oil contamination during flushing, packaging and sealing processes — an oilless design removes that hazard at the source. The twin-cylinder parallel-flow layout sustains the higher air demand of multi-station lines, while the F-class motor and thermal protection support continuous operating cycles without lubrication downtime.

OEM integration & laboratory — Equipment manufacturers also rely on the HC680 for centralized laboratory gas supply, aeration systems and analytical instrumentation. With a compact 275×130×208mm body, an installation footprint of only 223×89mm and a net weight of 9.9kg, OEM designers can integrate the pump directly into equipment housings without extensive structural modification. Dual voltage options allow instrument manufacturers to standardize their internal pneumatic design while shipping to different global regions.

Certifications & Compliance

Procurement engineers and OEM buyers require strict quality assurance and regulatory compliance to mitigate supply-chain risk. The HC680 is manufactured in an ISO 9001-certified facility, ensuring that every unit rolling off the production line adheres to strict quality management principles — consistent manufacturing tolerances, predictable performance across large-batch orders and a commitment to continuous product improvement for industrial buyers.

Furthermore, the HC680 series supports CE and RoHS compliance. The CE mark indicates conformity with European health, safety and environmental protection standards, supporting market access for OEMs exporting equipment to the European Economic Area. RoHS compliance confirms the pump is manufactured without restricted hazardous substances such as lead, mercury or cadmium — critical for manufacturers of medical devices and food-processing machinery that must meet environmental directives and ensure end-of-life recyclability of their products.

Frequently Asked Questions

What are the electrical requirements and thermal limits of the HC680?

The HC680 is available in two configurations to suit regional power grids: the HC680A-60/7 operates on 220V/50Hz/1, drawing ≤610W and running at 1400rpm, while the HC680B-60/7 requires 110V/60Hz/1, drawing ≤610W and running at 1700rpm. Both models deliver 60L/min at 700Kpa, feature Class F motor insulation and include built-in thermal protection that triggers automatically at 145±5°C. Capacitor values are 15μF for the 220V model and 60μF for the 110V model. The pump operates safely in ambient air temperatures between -5°C and 40°C.

Is the HC680 suitable for quiet, patient-care or laboratory environments?

Yes — this is where the HC680 excels. The 220V model operates at ≤60dB(A) and the 110V model at ≤61dB(A), making it one of the quietest oil-free compressors in its flow class. Combined with its 100% oil-free output, it prevents both acoustic disruption and chemical contamination in homecare, clinical and analytical settings.

How does the HC680 mount inside OEM equipment enclosures?

The HC680 is designed for straightforward integration into OEM machinery. Overall dimensions are 275×130×208mm, with a 223×89mm mounting footprint (4×M8 holes) and a net weight of 9.9kg — allowing the twin-cylinder unit to be installed into equipment housings with minimal structural modification.
