HC280D Oilless DC Air Pump | 24V, 340W, 25L/min @ 700Kpa

Why Choose the HC280D Oilless DC Air Pump

When an electric vehicle fleet operator requires a dependable tire inflation system that connects directly to a 48V vehicle architecture, standard pneumatic options often fall short. The HC280D oilless DC air pump provides a direct-drive solution that eliminates the need for bulky inverters or frequent maintenance intervals. By utilizing a wide voltage range capability from 12V to 560V DC, this pump integrates easily into modern high-voltage mobile equipment and off-grid setups, ensuring continuous operation even in extreme environments. Because it operates entirely without oil, there is no risk of lubricant contamination in the compressed air lines, nor is there a need for routine oil checks and changes. This significantly decreases the maintenance burden on your engineering team and ensures clean air output for sensitive applications.

Key Technical Specifications

Applications & Industries

The HC280D oilless DC air pump is engineered for demanding industrial environments where reliability and zero-oil contamination are strict requirements. In the realm of EV fleet maintenance, service vehicles require onboard pneumatic power that can operate directly from the vehicle's battery bank. When an electric vehicle fleet operator manages a large number of delivery vans or transit buses, maintaining optimal tire pressure is critical for maximizing battery range and minimizing tire wear. With its ability to handle high-pressure requirements up to 700Kpa and deliver 25L/min, this pump is highly effective for mobile tire inflation, pneumatic tool operation, and air suspension systems. The low 14.2A current draw at 24V ensures that the host vehicle's electrical system is not overtaxed during operation.

For solar-powered systems and off-grid applications, energy efficiency is a primary concern. The ≤340W power consumption makes the HC280D an excellent fit for remote installations powered by photovoltaic arrays. It is frequently utilized in remote environmental monitoring stations, off-grid water aeration systems, and agricultural pneumatic controls. Because the unit is entirely oilless and boasts a 70,000-hour lifespan, it requires zero lubrication maintenance, making it highly practical for isolated locations where regular technician visits are costly and logistically difficult.

Furthermore, mobile equipment manufacturers integrate this pump into specialized machinery that operates in extreme climates. Agricultural sprayers, street sweepers, and railway maintenance vehicles frequently require reliable compressed air for actuating valves, operating pneumatic cylinders, or clearing debris. The exceptional -50°C to 150°C operating range ensures that the pump functions correctly whether installed in heavy-duty mining equipment in the Arctic or construction machinery in desert environments. The compact 226x132x173 mm dimensions and standard 83x147 mm installation footprint allow OEM engineers to easily design this compressor into tight engine compartments or utility boxes.

Certifications & Compliance

Procurement engineers and OEM buyers must ensure that integrated components meet strict international standards. The HC280D carries full CE certification, guaranteeing compliance with European health, safety, and environmental protection legislation. This allows equipment manufacturers to confidently export their finished machinery into the European Economic Area (EEA) without facing regulatory delays regarding pneumatic sub-components.

Additionally, the pump is RoHS compliant, meaning it is manufactured without the use of hazardous materials such as lead, mercury, or cadmium. This is a critical requirement for electronics and electrical equipment distributed globally. The IP54 rating provides certified protection against significant dust ingress and splashing water from any direction. The "5" in IP54 indicates that the unit is protected against dust that could interfere with the normal operation of the equipment, while the "4" signifies protection against water splashed from all directions. This level of ingress protection ensures the internal motor and pump mechanisms remain protected in harsh industrial or outdoor environments.

Frequently Asked Questions

What are the installation dimensions and weight of the HC280D?

The HC280D features a compact physical footprint with overall dimensions of 226 mm by 132 mm by 173 mm. For mounting, it utilizes a standard 83 mm by 147 mm installation size requiring four M6 bolts.
