Mobile Diesel Air Compressor 275CFM
- Engines with Mechanical Fuel Pumps: The mechanical fuel pump is driven by a cam, featuring a simple structure that avoids the risk of electrical component failure and ensures high reliability. Compared with electric pumps, mechanical pumps have lower costs and maintenance costs, and maintenance only requires replacing basic seals and diaphragms. It has a high tolerance for diesel viscosity and impurities, and can adapt to fuel standards at different national levels without advanced filtration or modification. Even at high altitudes or in severe cold environments, the output flow and pressure fluctuations of the mechanical pump are small, ensuring a continuous and stable fuel supply. The regular maintenance cycle is long, and key components (such as the pump body and diaphragm) wear slowly, greatly reducing the failure rate and downtime losses.
- GHH German process compressor head: precision manufacturing, durable.
- Nano-level double-layer filtration air filter: micron-level carrier material, achieving efficient retention of 0.1–5 µm particles (efficiency ≥99.99%).

Features
- The exhaust volume is sufficient and air pressure is constant, 275cfm and 7bar.
- Portable modle, easy to move.
- Powerful engine helps to improve reliability and reduce fuel consumption.
- SKF bearings for air end, long life time around 10 years.
- Beautiful appearance, attracting clients.
- Axle: This part connecting compressor to the ground, including suspension system, wheels and all related parts. Suspensions can be assured with springs (sprung axle) or leaf springs (leaf spring axle). Wheels are of different size, to match the weight of the machine and according to the type of towing.
- Lights: System with rear lights and reflectors
- Drawbar: The drawbar is the rigid connection between diesel powered air compressor and towing vehicle. It can be at fixed height (gooseneck bend or straight angles) or adjustable through joints.
- Connection: This is the mean to connect physically the drawbar to the towing vehicle. It can be through tow eyes or ball concection, both of different diameter.
- Low noise: Their enhanced safety features and very low noise levels make them the perfect choice for any jobsite.
- Easy Maintenance: Quick access air connections and large gullwing doors provide easy access for maintenance and servicing. Some portable air compressor China models may have interior storage compartments for storing tools and accessories.
- Colur: Customed
- Exclusive pneumatic control system: developed by CFAIR, to adjust automatically engine rotation speed, depending on the air to be delivered.This system is highly reliable and ensures fuel consumption saving.
