HLT Series Combined Mobile Screw Air Compressor Unit (4-in-1 Trailer-Mounted Air Source System with Compressor + Air Tank + Dryer + Filters)

This HLT series combined mobile air compressor unit is an intelligent air compression system that highly integrates the screw compressor main unit, air receiver tank, refrigerated air dryer, and precision filters onto a towable mobile chassis. The core working principle is: air enters the screw compressor chamber through the intake filter, and is compressed continuously and smoothly by the twin-screw rotors, forming a high-temperature, high-pressure oil-air mixture. This mixture undergoes three-stage separation in the oil-air separator, and the purified compressed air then sequentially enters the integrated air receiver tank for buffering and pressure stabilization, the integrated refrigerated air dryer for cooling and dehumidification (with pressure dew point reaching 2~10℃), and then passes through multi-stage precision filters (filtration accuracy up to 0.01μm, oil content ≤0.01ppm) to remove residual oil mist and dust particles. The entire compression, purification, and storage process is integrated onto a trailer-mounted chassis—users simply tow the unit to the jobsite, connect the power supply or start the diesel engine, and begin operation immediately, achieving a convenient “tow-and-go, plug-and-play” working mode. This HLT combined mobile air compressor unit is available with either electric or diesel power options to suit different jobsite power conditions.

In terms of manufacturing quality and structural integrity, this HLT combined mobile air compressor unit adopts a modular integrated design philosophy. The core—the screw compressor main unit—features high-efficiency asymmetrical rotor profile design with SKF heavy-duty bearings, ensuring smooth and reliable operation with overhaul intervals reaching 40,000 to 80,000 hours. The compressor main unit and motor/diesel engine are connected via coaxial direct coupling or high-elasticity coupling with no intermediate speed-increasing gear, delivering higher efficiency, better reliability, and longer service life. The entire unit features an enclosed box-type structure with low noise and low vibration design; spacious maintenance doors provide easy access to all serviceable components, reducing downtime. The mobile chassis features a single-axle or tandem-axle trailer design with pneumatic tires, an adjustable tow bar, and handbrake device, suitable for various road conditions; the unit is also equipped with lifting lugs and fork-lift pockets for easy hoisting and transportation. The integrated piping system is optimally designed, significantly reducing the length and number of pipe connections, effectively lowering the risk of pipeline leakage and system pressure drop. The refrigerated air dryer features an efficient heat recovery design and environmentally friendly refrigerants, ensuring stable and dry compressed air even under high-temperature conditions. The entire unit is equipped with a PLC or microcomputer intelligent control system, continuously monitoring operating parameters including discharge pressure, discharge temperature, oil pressure, and coolant temperature, with automatic alarm and shutdown protection functions.

The performance advantages and application value of this HLT combined mobile air compressor unit are exceptionally prominent. First, highly integrated and tow-and-go ready – the air compressor, air receiver tank, refrigerated air dryer, and filters are all integrated onto a mobile chassis; users do not need to separately purchase, install, and connect each component—simply connect power upon arrival and start operation, dramatically saving installation time and space. Second, flexible mobility and strong adaptability – the trailer-mounted chassis design allows easy relocation to different jobsites, particularly suitable for field operations without fixed air supply and requiring frequent relocation; optional diesel engine, electric motor, or battery drive adapts to high altitude, low temperature, dusty, and other harsh conditions. Third, high-quality output air – after integrated refrigerated drying and precision filtration, the compressed air achieves a pressure dew point of 2~10℃, oil content ≤0.01ppm, and dust particle size ≤0.01μm, directly meeting high-demand applications such as sandblasting, painting, and laser cutting. Fourth, intelligent energy-saving operation – supports 0~100% infinitely variable air flow control with automatic load matching, combined with automatic diesel engine throttle adjustment or permanent magnet variable frequency drive, maximizing fuel/electricity savings. Fifth, all-weather operation capability – equipped with oversized coolers designed for harsh field environments; rugged chassis and large-diameter wheels suit various road conditions.

In terms of application scope, this HLT combined mobile air compressor unit is widely used in sandblasting rust removal (providing continuous, stable high-pressure airflow for mobile sandblasting machines, ensuring surface treatment grade reaches Sa2.5 or above), outdoor anti-corrosion engineering (bridge and steel structure on-site anti-corrosion construction), mining (driving rock drills, jackhammers, and other equipment), highway and railway construction (tunnel construction, anchoring construction), water conservancy engineering, shipbuilding, urban construction (jackhammer piling, exterior stone-like paint spraying), petrochemical pipeline construction, and military support. This HLT series combined mobile air compressor unit is an efficient, reliable, high-quality one-stop compressed air solution for modern field mobile construction.
