Lubricated Screw Type Air Compressors – High Efficiency, Low Maintenance Looking for a reliable and energy-efficient compressed air solution? At PPI Engineers, we offer a premium range of Lubricated Screw Type Air Compressors, ideal for continuous-duty industrial applications. These compressors are engineered for performance, durability, and reduced operational costs. Lubricated screw compressors use oil to cool, seal, and lubricate the internal rotors, ensuring consistent airflow, minimal wear, and longer service life. They are perfect for manufacturing, packaging, textiles, pharmaceuticals, and many other industries requiring uninterrupted air supply.

At PPI Engineers, we offer high-performance Piston Air Compressors designed to meet the demands of various industries. Also known as reciprocating air compressors, these machines are ideal for applications requiring intermittent or continuous compressed air supply with dependable power output. Our piston air compressors are built for durability, efficiency, and easy maintenance, making them perfect for automotive workshops, manufacturing units, small-scale industries, construction sites, and more.

55-250kW DIRECT ROTARY SCREW AIR COMPRESSORS Our most energy-efficient air compressor to date, the NxHE Series compressors use patented two-stage airend technology to provide efficient operation with outstanding durability and offer the lowest life-cycle cost of any compressor on the market. Description TWO-STAGE COMPRESSION: SETTING THE STANDARD FOR ENERGY EFFICIENCY Compared to single-stage rotary screw compressors, a two-stage is much closer to isothermal compression. This is achieved by injection of fresh oil between the stages which reduces the inlet temperature to the second stage. This lower inlet temperature increases efficiency by reducing the compression ratio between the stages. In addition, leakage between the rotor seals is significantly reduced resulting in outstanding volumetric efficiency. Two-stage air compressors are closer to the ideal isothermal compression: • Reduced leakage increases volumetric efficiency • Saves 10-15% of energy compared to single-stage compressors • Increases flow 10-15% compared to single-stage compressors • Lower pressure differential increases efficiency and reliability • Low heat load • Easy maintenance and service • Lowest life-cycle cost of any compressor on the market eCOOL® TECHNOLOGY The ultimate in system protection and reliability • Protects critical components from compressor-generated heat • Compartmentalized air flow design and oversized aftercooler • Extends component life and reduces downtime ENERGY EFFICIENT TWO-STAGE AIREND Energy-saving and Eco-friendly • Patented airend design integrates the first and second stage rotors into one airend • Oil is injected between the first and second stages to cool the air and optimize efficiency • Splitting the compression cycle into Two-stages reduces the axial and thrust loading to which improves service life of airend and bearings • Two-stage compression significantly reduces noise EFFECTIVELY INTEGRATED OVERALL DESIGN Designed for low cost of ownership, easy service & little down time • Safe, efficient air filter system • Independent bearing lubrication • High efficiency, easy-to-maintain oil separator • IE3 high efficiency motor • End face sealed to prevent leakage • Connections utilize o-ring face seals for leak–free performance • Asbestos-free gaskets protect operator health
