Anyone in construction knows how troublesome it is to supply compressed air for
Drilling Rigs. Traditional diesel compressors are heavy and noisy; once they arrive at the site, you have to refill them with fuel—fuel costs alone can eat up nearly half of your daily profit. Even more frustrating is when dealing with excavator-converted drilling rigs: their original hydraulic systems are already under strain, and adding an external diesel
Air Compressor further burdens both the hydraulic pump and engine, causing frequent breakdowns. Customers often complain bluntly: "We lose time just maintaining this air compressor." It's even worse for
Drilling And Splitting Machines, which already rely on high air consumption from their built-in pneumatic breakers. When combined with unstable air supply from a separate compressor, operations become intermittent—making it impossible to properly split rocks.
To tackle these frustrating issues, ANNENG introduced the YQ55
Hydraulic Air Compressor—a bold solution that runs directly on equipment's hydraulic oil. It requires no additional lubrication or separate engine; simply connect the oil inlet hose to the return line of an excavator,
Drilling Rig, or any hydraulic system, turn on the switch, and compressed air is instantly available. This eliminates key pain points: saving on diesel costs, reducing transport weight, and cutting equipment failure points in half. Especially when paired with compact converted rigs like
Excavator Converted Drilling Rigs, the YQ55 can fit snugly into the empty space behind the operator’s cab. With just one oil hose and one air hose connected, drilling can begin within ten minutes.
How effective is it? At an open-pit mine in Guangxi, they previously used two diesel air compressors to power five pneumatic drilling rigs. The daily fuel cost exceeded 2,000 yuan, and the compressors frequently shut down due to overheating. Later, they replaced them with a YQ55 unit connected to the hydraulic circuit of a 360 excavator, which easily supplied compressed air for three drilling rigs. Even after continuous operation for eight hours, the oil temperature never exceeded 85 degrees Celsius. The boss did the math: they saved nearly 400,000 yuan annually on fuel alone, and no longer experienced delays caused by compressor failures.
Product Features (three points, remember them well):
Oil-free and electric-free: Pure hydraulic drive eliminates the need for external power sources or fuel, making it ideal for drilling and splitting machines operating in remote areas without electricity.
Automatic flow matching: Built-in pressure compensation valve adjusts output automatically—high hydraulic flow produces more air, while low flow reduces output to prevent engine power waste. Real-world tests show over 30% better fuel efficiency compared to compressors of the same displacement.
Durable design: Thick cast aluminum housing passes 500 hours of vibration testing, ensuring reliability even on rough mining terrain. All fittings are stainless steel—rust? Not a chance.
Quick tips (just two, remember them):
① When connecting hydraulic lines, always install a return oil filter (10 microns) before the inlet to prevent metal shavings from clogging the compressor valve.
② In winter, idle the system for five minutes to warm up the hydraulic oil before starting the compressor, as cold oil has high viscosity and may cause rotor seizure.
Ultimately, the ANNENG YQ55 is designed to save drilling operators' time and effort. Whether you're supplying air to conventional drills, modified excavator-based drilling rigs, or drilling and splitting machines equipped with pneumatic hammers, it can operate as long as there's a hydraulic power source available. This single machine replaces those bulky diesel air compressors of the past, and maintenance is simple—just replace the bearing grease once a year. This minimalist approach is exactly how construction machinery should evolve.
