HC480D Oilless DC Air Pump | 560W, 45 L/min @ 700Kpa, 24V, IP54

Why Choose the HC480D Oilless DC Air Pump

Picture a construction equipment OEM needing a reliable pneumatic source installed directly within an engine compartment that reaches 150°C. Traditional lubricated compressors degrade rapidly under extreme thermal stress, leading to fluid breakdown, system failure, and expensive warranty claims. The HC480D oilless DC air pump solves this thermal challenge, providing consistent 700Kpa pressure without relying on oil lubrication. This ensures continuous operation even in the harshest industrial environments, reducing the need for frequent servicing and protecting downstream pneumatic components from oil contamination.

• High-Pressure Performance: Delivers a consistent 45 L/min air flow rate at a rated pressure of 700Kpa, driven by a highly efficient ≤560W motor.
• Extreme Temperature Tolerance: Engineered to function reliably in severe ambient temperatures ranging from -50°C up to 150°C.
• Extended Service Life: Features an exceptional 70,000-hour operational lifespan, significantly minimizing replacement frequency and maintenance overhead for OEMs.
• Quiet Operation: Runs at a low noise level of ≤65dB(A) at its 1700rpm rated speed, ensuring compliance with occupational noise limits in enclosed workspaces.
• Flexible Power Integration: Operates efficiently on a DC24V power supply with a low 23.33 A current draw, while the series supports a wide voltage range of 12V-560V DC for custom applications.
• Certified Quality & Protection: Meets strict international manufacturing standards with CE and RoHS certifications, alongside an IP54 rating for environmental protection.

Key Technical Specifications

Applications & Industries

The HC480D oilless DC air pump is engineered for heavy-duty commercial and industrial sectors that demand reliable pneumatic power without the maintenance overhead of oil lubrication. In EV fleet maintenance, mobile service vehicles require compact, high-pressure air sources for commercial tire inflation, pneumatic tool operation, and diagnostic equipment. When technicians are repairing electric vehicles on the roadside, they depend on fast, high-capacity air delivery. With its DC24V power requirement and ≤560W output, this pump connects directly to the service vehicle's electrical system, delivering a steady 45 L/min at 700Kpa without draining the primary battery excessively or requiring a bulky, separate generator.

For solar-powered systems and off-grid applications, energy efficiency and autonomy are critical purchasing factors. The HC480D integrates seamlessly into remote environmental monitoring stations, agricultural aeration systems, and off-grid pneumatic valve controls. Its low 23.33 A current draw at rated pressure makes it highly compatible with standard solar charge controllers and battery banks. Furthermore, because the unit is entirely oil-free, there is zero risk of lubricant contaminating sensitive environments, making it ideal for aquaculture facilities and remote water treatment plants. The 70,000-hour lifespan ensures that these remote installations operate continuously for years without requiring costly technician dispatch for pump maintenance.

Mobile equipment manufacturers also utilize this compressor for onboard pneumatic systems in construction, agricultural, and mining machinery. The IP54 protection rating shields the internal components from dust ingress and water spray, which are constant threats on active job sites. Additionally, the extreme temperature tolerance (-50°C to 150°C) allows engineers to mount the compact 7 kg unit (measuring 276*133*180 mm) close to engine compartments or hydraulic power units where ambient heat would quickly destroy standard commercial pumps.

Certifications & Compliance

For OEM buyers and procurement engineers, regulatory compliance is a primary factor in component selection. The HC480D carries full CE certification, ensuring that it meets the stringent health, safety, and environmental protection standards required for machinery sold within the European Economic Area (EEA). This allows European manufacturers to integrate the pump into their larger systems without facing regulatory friction or delays during final product certification. By selecting a factory-certified component, procurement teams reduce time-to-market for their end products.

Additionally, the pump is RoHS compliant, guaranteeing that it is manufactured without hazardous materials such as lead, mercury, or cadmium. This aligns with global sustainability initiatives and supports corporate ESG (Environmental, Social, and Governance) goals. The IP54 rating provides certified protection against harmful dust accumulation and splashing water from any direction. This ingress protection is vital for outdoor applications, ensuring the pump maintains its 70,000-hour lifespan even when exposed to harsh weather conditions, road debris, or industrial washdowns.

Frequently Asked Questions

What are the installation dimensions and physical weight of the HC480D model?

The HC480D is designed for compact integration, with overall dimensions of 276x133x180 mm and a net weight of 7 kg. For mounting, the specific installation size is 89x223 mm, utilizing four M6 bolts (4xM6) to secure the unit firmly within mobile equipment chassis or stationary utility enclosures, minimizing vibration during its 1700rpm operation.

Is the HC480D suitable for 24V solar-powered off-grid systems?

Yes, the HC480D is highly suitable for solar-powered systems and remote off-grid applications. It operates natively on a DC24V power supply, drawing 23.33 A at its rated pressure of 700Kpa. This direct current compatibility allows it to be wired directly to 24V battery banks charged by solar panels, avoiding the energy losses typically associated with DC-to-AC power inverters.

How does the IP54 rating benefit outdoor mobile equipment applications?

The IP54 rating indicates that the pump is protected against dust ingress sufficient to prevent interference with normal operation, and it is protected against splashing water from any angle. This makes it highly effective for mobile equipment and EV fleet maintenance vehicles, where the pump may be exposed to road dust, dirt, and light rain during daily field operations.
