Air Compressor Introduction
Our compressors are manufactured according to the most stringent standards in the world.Our highest pressure reaches 450BAR(45MPA).Our compressors can compress air and inert gases.
The compressor has a sturdy rigid chassis for easy movement.The chassis is made of aluminium steel plate and reinforced by structural parts.The small equipment is equipped with a handle for easy movement..
The vertical compressor is an integral skid-mounted structure,which is derived from industrial applications and has been continuously improved to meet the requirements of high-pressure compressors.The compressor adopts air-cooled cylinder with high compression ratio and high efficiency.The compressor has a balanced design with low vibration and no special foundation is required.In some cases,it can even run on a high-density rubber liner.
The outlet of each stage of the compressor is equipped with an air-cooled cooler,a safety valve,a gas-water separator,and an automatic drain valve.All internal pipelines and connections are installed before leaving the factory,which is convenient for on-site installation
Characteristics Of Air Compressor
Designed for maximum efficiency. |
Our compressors feature interchangeable cylinders,cylinder heads,pistons and valves. |
We can offer compressors customized for wide ranges of pressure and volume at highly competitive prices. |
Adopting high speed,high compression ratio and low temperature rise design,which greatly improves the charging efficiency and prolongs the service life of the unit |
No special foundation required;compressors can be mounted on existing concrete floors. |
Optional custom filters. |
Multiple innovative designs improve efficiency and compressor productivity |
Our design provides extremely high volumetric efficiency despite continuous or intermittent operation |
Dynamically balanced to minimize vibration. |
Built for rugged performance. |
Unique pressurized crankcase recovers all piston ring blow-by,further increasing compression efficiency. |
Total oil carryover in most applications is just 10 to 15 ppm,with an optional oil removal system available to reduce oil carryover to 0.5 ppm. |
Internal components feature built-in guides and alignment for easy maintenance. |
