low pressure series JN screw air compressor for textile machinery and waste water treatment project    Product Description 1. KAITIAN Series low pressure compressor: Power range: 22KW - 355KW Working pressure: 0.3MPa - 0.5MPa Capacity (FAD): 6.5 m³/min - 92m³/min    KAITIAN 0.3MPa-0.5Mpa high volume low pressure compressor is designed for industries on textile, printing, dyeing, glass, cement,  water treatment, chemical etc.  They can save 20% - 50% energy than using regular air compressor 0.7-0.8Mpa.   Feature   Domestic origination: For textile,cement,glass industry specially make--- Kaitec 50Hz 0.3Mpa series low pressure screw air compressors   When applications of working pressure between 0.2 - 0.5Mpa, the selected conventional 0.7Mpa air compressor will cause a huge waste of electricity, the choice of low pressure screw air compressors in the same motor power can be a substantial increase in the compressed air production, energy saving could be up to 20-50% .   If you purchased the 0.7Mpa machine, while the actual use of working pressure is 0.3Mpa, its working process is usually like this: first air compressed to 0.7Mpa,then through the pressure reducing valve reducing its pressure to 0.3Mpa to use it . In other words, you are using 0.3Mpa pressure while withstand 0.7Mpa power consumption.   This also could be proved from the capacity:   A 132kW, 0.7Mpa screw air compressor, its capacity is 24m³/min. However choosing KHE132kW, 0.3Mpa screw compressor, the capacity more than 37m3/min,the electricity savings will allow you to recover the investment in less than a year.   According to user's use of pressure, these series automatically could adjust the compression ratio in the working pressure range of 0.2 ~ 0.5Mpa, and could maintain the best specific power (energy efficiency).   Pump forced lubrication--Make sure that there is sufficient fuel injection in low working pressure and the best oil and gas mixing ratio.   The oil pump forced lubrication:
Ensure that there is enough fuel injection quantity even in very low exhaust and the best oil and gas mixing ratio.     High Efficient Airend Using high efficient airend Speical designed rotors teeth produce exceptional high quality airend Reliable bearing provide extended bearing operating life. Using triplexbearing to prevent oil leakage. Special designed, harden shaft seal O-ring to provide reliable shaft sealing. Using industrial well known components in assembly, smaller motor produce more air capacity.
Cooling system: Large cooler and larger fan allow extreme working condition.
Control System: Total Management and contorol of all compressor operating parameters including: Operating parameters display , warning and stop alarms. Programmed maintenance schedules Recording of compressor history   High efficient motor: Large torque setting F class insulation, protection grade-IP54 SKY bearing,low operating sound, extended operating life Lubricant filler design ,lubricant can be refilled when motor is in operation.       Specification
