Product Details

If your equipment only needs compressed air below 0.5 bar, choosing a 2~5.5 bar low-pressure screw air compressor can save more than 30% of electricity compared to the common 8 bar screw air compressor. ROCKY's 2~5.5 bar low-pressure screw air compressor, which is specially tailored for the textile, cement, glass and other industries, has been fully recognized by the majority of users in terms of saving electricity.

Product features of low pressure screw air compressor
1. Adopt large rotor and low speed to ensure high performance of the machine;
2. Increase oil and gas separation equipment to ensure that the export oil content is ≤3ppm;
3. The air source of the low-pressure screw air compressor is clean, which reduces the number of cleaning nozzles of texturing machines and other equipment, and improves the quality of the finished product;
4. The heat dissipation area of the oil cooler is increased by more than 30% to ensure normal operation in summer without over-temperature;
5. Independently design the internal pressure ratio of the host to ensure a better specific power;
6. Intelligent control system, automatically adjust the exhaust volume according to the customer's usage (frequency conversion model).
7. For the texturing industry, ensure long-term continuous operation, set fault warnings, and do not stop immediately, so that customers are fully prepared for shutdown;
8.  Adopting dual air outlet design, the air outlet temperature can be adjusted according to climate changes, meeting customer needs to a greater extent, and achieving high efficiency and energy saving at the same time.
