Product Features
At the same power input, two-stage compression delivers around 25% more air output than single-stage compression.
2)Exceptional Durability
Bearings and gears operate under lower load, which extends the service life of the airend.
3)Lower Maintenance Costs
With two airends sharing the workload at identical power, bearings bear less stress and achieve a longer service life.
The integrated screw airend is half the size of conventional airends. The lubricating oil required for each maintenance cycle is approximately 50% of that for standard screw air compressors, greatly cutting maintenance expenses.
Control & Electrical System
Supports Chinese/English bilingual setting, and parallel connection of up to 16 units.
Dual-path pressure monitoring: internal pressure of oil-gas separator tank and unit exhaust pressure, providing better protection for the unit.
Real-time exhaust temperature monitoring to guarantee stable unit operation.
Adopts MODBUS RTU protocol with RS485 interface, compatible with user upper monitoring systems.
Permanent Magnet Synchronous Motor
Two-stage Screw Air Compressor built with permanent magnet material resistant to 180°C high temperature for long service life.
Fully enclosed structure with IP54 protection class.
IE4 ultra-high energy efficiency rating.
Oil-Gas Separation System
High-efficiency air compressor oil-gas separator, residual oil content in compressed air ≤3ppm.
Highly recovered and recycled lubricating oil effectively prevents oil carryover.
High-performance filter element with long service life, no frequent replacement required.
Humanized quick-disassembly design for oil separator cover, easy replacement to save time and labor.
Asynchronous Motor
IE3 high energy efficiency rating.
Designed by DEMON with professional customization.
Self-cooled motor, F-class insulation, B-class temperature rise, IP54 protection class.
Screw Airend
The screw airend is the core component of Two-stage Screw Air Compressor; its performance directly affects the overall operating cost and service life of the whole machine.
DEMON custom-designed airend delivers over 5% higher energy efficiency than similar mainstream products on the market.
The airend runs smoothly even under harsh working conditions with frequent start-stop cycles.
Air Filter System
Front pre-filter blocks large particulate contaminants from entering the compressor, acting as the first line of defense for compressed air; easy to clean and disassemble.
Premium nano air filter with dust removal precision of 3μm at 99.9% efficiency, adopting dual-stage filtration of flow guide swirl and paper fiber, suitable for heavy dust production and various harsh environments.
Integrated air filter design requiring no extra tools for disassembly, enabling quick replacement and simplified filter maintenance service.
