Large Cooling Surface
A high-capacity cooling package allows reliable operation in harsh environments with ambient temperatures up to 50°C.
High-Efficiency Filtration
High-efficiency multi-step fuelfiltration with water separatorisolates and traps contaminants
High Efficiency,Excellent performance Productswith Famous brand Engine
Advanced Screw Element Technology
The asymmetric rotors allow for increased efficiency. In addition, a low rotor speed and few moving parts minimize wear and tear for reliable performance and a long service life.
Clean Intake Air
A high performance two-stage air intake filter prevents dust and dirt particles from entering the engine and compressor. A service indicator an the filter tells you when it needs replacing.
Reputable Engine Brands
Every model has a carefully selected engine from a well-knownand respected partner. All components are protected insidethe corrosion treated weatherproof hood.
