What are Low Air Pressure Compressors?
Air pressure compressors are devices used to convert power into potential energy stored as compressed or pressurized air. They are essential in various industries, from workshops to construction to households. Compressed air applications require a specific pressure for normal operation. While some applications require high pressure, others need low pressure. So, air compressors are available in the following categories: high, medium, and low.
Low-pressure air compressors are the specific category used for low-air pressure applications.They deliver working pressure of 3 – 5 bar (43.5 – 72.5 psi) and are used in small businesses, workshops, auto body repair centers, small manufacturing plants, and tire workshops.
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.

What are the Applications of Low-Pressure Air Compressors?
Many applications, such as pneumatic conveyance to wastewater treatment, need low-pressure air compressors. While most of them require an operating pressure of one bar or less, they have varying run and load times. For example, the pneumatic conveyance of heavy goods requires nearly a constant flow rate despite fluctuating pressures. Other applications, especially in the field of fluid aeration, need a variable flow rate, but the pressure curve should be virtually constant over time. Low-pressure breathing air compressors will work efficiently for applications requiring a pressure between 0.3 and 4 bar (g).
Examples of industries that use low-air-pressure compressors include:
Cement manufacturers: Cement manufacturing plants require air compressors releasing low pressure for various applications, including mixing and conveying materials and cleaning and sealing cement bags.
Treatment of wastewater: Low-pressure air compressors assist in aeration to supply the processing bacteria with oxygen and agitation to maintain solids in suspension.
Mills: Pulp and paper mills require low-pressure air compressors to supply a continuous flow of clean, dry air and help maintain a near-constant production rate.
Glass: The glass industry uses air compressors producing low pressure to assist in glass liquid combustion and conveying the mix from one chamber to the other.
Mining: Low air pressure helps in the safe handling of fine materials such as coal dust.
Fermentation: Low-pressure air compressors help increase oxygen which helps bacteria complete the fermentation process.
Pneumatic conveying: Low-air pressure compressors provide a combination of pressure that transfers materials across different processing centers in pneumatic conveying.

What are Low Air Pressure Compressors?
Air pressure compressors are devices used to convert power into potential energy stored as compressed or pressurized air. They are essential in various industries, from workshops to construction to households. Compressed air applications require a specific pressure for normal operation. While some applications require high pressure, others need low pressure. So, air compressors are available in the following categories: high, medium, and low.
Low-pressure air compressors are the specific category used for low-air pressure applications.They deliver working pressure of 3 – 5 bar (43.5 – 72.5 psi) and are used in small businesses, workshops, auto body repair centers, small manufacturing plants, and tire workshops.
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.

What are the Applications of Low-Pressure Air Compressors?
Many applications, such as pneumatic conveyance to wastewater treatment, need low-pressure air compressors. While most of them require an operating pressure of one bar or less, they have varying run and load times. For example, the pneumatic conveyance of heavy goods requires nearly a constant flow rate despite fluctuating pressures. Other applications, especially in the field of fluid aeration, need a variable flow rate, but the pressure curve should be virtually constant over time. Low-pressure breathing air compressors will work efficiently for applications requiring a pressure between 0.3 and 4 bar (g).
Examples of industries that use low-air-pressure compressors include:
Cement manufacturers: Cement manufacturing plants require air compressors releasing low pressure for various applications, including mixing and conveying materials and cleaning and sealing cement bags.
Treatment of wastewater: Low-pressure air compressors assist in aeration to supply the processing bacteria with oxygen and agitation to maintain solids in suspension.
Mills: Pulp and paper mills require low-pressure air compressors to supply a continuous flow of clean, dry air and help maintain a near-constant production rate.
Glass: The glass industry uses air compressors producing low pressure to assist in glass liquid combustion and conveying the mix from one chamber to the other.
Mining: Low air pressure helps in the safe handling of fine materials such as coal dust.
Fermentation: Low-pressure air compressors help increase oxygen which helps bacteria complete the fermentation process.
Pneumatic conveying: Low-air pressure compressors provide a combination of pressure that transfers materials across different processing centers in pneumatic conveying.
