ASU Screw Air-End
The ASU screw air-end is the heart of every Airpol screw compressor, responsible for its performance, efficiency, and reliability throughout its entire service life. It is designed by Airpol's Research and Development specialists, drawing on years of experience in compressed air technology, and manufactured to the highest quality standards.
The range includes screw air-ends for compressors from 7.5 to 110 kW and working pressures from 5.5 to 15 bar. Precision manufacturing, rigorous quality control, and an optimized rotor profile ensure high performance, low energy consumption, and a long service life.
Highest Manufacturing Quality
Every screw air-end is manufactured to very high precision and undergoes thorough quality control and final testing. This precision translates into reliable operation and a long service life.
High Performance
The proprietary ASU rotor profile ensures a tight meshing seal, reducing internal leakage. An optimized oil injection point and improved inlet channel increase compression efficiency and improve the performance of the entire system.
Low Energy Consumption
A specially designed outlet channel reduces pressure drops, while an optimized torque characteristic and reduced internal friction help lower energy consumption during operation.
Durability and Reliability
A robust design and oversized bearings ensure a long service life for the screw air-end. The first bearing regeneration is not required until approximately 20,000–30,000 operating hours, and the design is built for continuous 24/7 operation.
Quiet and Stable Operation
An optimized outlet channel and a properly designed screw profile reduce vibration and noise levels, ensuring smooth, stable operation of the entire compression unit.
Versatile Application
The screw air-end can be foot- or flange-mounted and is compatible with various types of drives, including variable frequency drives. Its wide configuration range makes it suitable for many types of industrial compressors.
Easy Service Access
The design provides quick access to serviceable components. Simplified maintenance procedures and easy seal removal reduce inspection time and lower operating costs.
