L-type Compressor Specification
L-type compressor is an angle compressor with compact construction and good dynamic balance. Each crank possesses at most one bell crank and can be equipped with more than two connecting bars. The crank is simple, short and can apply rolling bearing. The resultant force of each column's first ordered inertia force can be partially or full equilibrated by the balanced weight on the cranks, so as to achieve high running speed and fine dynamic balance. L type Compressor not only poossesses the advantages of angle compressors,but also has its own strong points in that it runs more stable than V-type and W-type. 
Besides general gas such as air, the compressed medium may also include flammable and explosive gas, such Natural Gas and Coal Gas as well as special gas which are toxic and corrosive. KEEPWIN has taken a series of technical measures in aspects such as structure material, explosion prevention, anto-control and protection to guarantee safety and reliability. Products are widely used in variety of industries such as Petroleum, Chemical textile, Gas Separation, Metallurgy Mine Machinery.
