Recommended Applications
KEL Series Low pressure screw air compressor is a new compressor produced according to the national policy of energy saving,emission reduction and environment protection. It changes the traditional compressor with relatively high pressure. It transfers the compressed air after pressure reduction to the air consumer, which waste large amounts of energy.
The low pressure screw air compressor can be distributed according to the air pressure of the user, to satisfy the process flow with minimum energy. The manufacturing cost of your product can be largely improved.
For example, if your process system only needs 3 bar pressure and the used compressor can provide 7 bar, then it can be reduced to 3 bar, It may take two times power to satisfy you process system, you can choose our low pressure screw compressor only to consume half of the power, and the air pressure in the process system can still be ensured, thus realizing energy saving and emission reduction.
Frequently Asked Questions
Using a standard compressor and reducing the pressure to 2 or 3 bar wastes significant energy. The KEL series is specifically engineered for 1.5-5 bar, allowing for larger air discharge with much lower power consumption, saving you up to 30% or more on energy bills.
The KEL series is optimized to deliver stable compressed air within the 1.5 bar to 5 bar (21-72 PSI) range. This ensures the highest volumetric efficiency for industries that do not require high-pressure air.
This series is ideal for textile manufacturing (weaving/spinning), cement conveying, glass bottle production, chemical fiber processing, and wastewater treatment aeration, where high volume and low pressure are required.
By utilizing an optimized screw airend designed for low-pressure ratios, the KEL series can provide a much larger air delivery (m³/min) than a standard compressor of the same motor power, perfectly meeting the demand for high-volume air.
Yes. Like all Kotech industrial units, the KEL series features a heavy-duty design with superior cooling systems and high-quality bearings, ensuring 100% duty cycle and maximum reliability in harsh factory environments.
No. The maintenance procedures are similar to standard screw compressors. However, because it operates at lower pressure, the internal stress on components is reduced, which often leads to a longer service life for seals and bearings.
Certainly. We offer various motor powers and configurations. Our engineers can help you calculate the exact pressure and flow requirements for your specific production line to ensure the highest possible ROI.

Frequently Asked Questions
Using a standard compressor and reducing the pressure to 2 or 3 bar wastes significant energy. The KEL series is specifically engineered for 1.5-5 bar, allowing for larger air discharge with much lower power consumption, saving you up to 30% or more on energy bills.
The KEL series is optimized to deliver stable compressed air within the 1.5 bar to 5 bar (21-72 PSI) range. This ensures the highest volumetric efficiency for industries that do not require high-pressure air.
This series is ideal for textile manufacturing (weaving/spinning), cement conveying, glass bottle production, chemical fiber processing, and wastewater treatment aeration, where high volume and low pressure are required.
By utilizing an optimized screw airend designed for low-pressure ratios, the KEL series can provide a much larger air delivery (m³/min) than a standard compressor of the same motor power, perfectly meeting the demand for high-volume air.
Yes. Like all Kotech industrial units, the KEL series features a heavy-duty design with superior cooling systems and high-quality bearings, ensuring 100% duty cycle and maximum reliability in harsh factory environments.
No. The maintenance procedures are similar to standard screw compressors. However, because it operates at lower pressure, the internal stress on components is reduced, which often leads to a longer service life for seals and bearings.
Certainly. We offer various motor powers and configurations. Our engineers can help you calculate the exact pressure and flow requirements for your specific production line to ensure the highest possible ROI.
