--Main Characters of Shangair Brand Specially for PET Bottle Blowing High-pressure  Air Compressor: 

• High reliability; ability to work 24 hours per day.
• Low exhaust temperature (when exhaust pressure is 7.0 Mpa, exhaust temperature is equal to or less than 170; aftercooler-processed temperature at outlet is only 15 to 20 higher than ambient temperature) and oil consumption is low (oil consumption is less than 2.6g/h). 
• Advanced Shangair patented direct-flow valve technology is used for low pressure air compressor, which increases air output by 13% and reduces energy consumption by 11%,
• Ring valve made from Sweden stainless steel strip is used for high pressure air compressor.
• In order to ensure safety and reliability of air compressor, redundancy design principle is applied and multiple protection measures are taken; overload protection; overheat protection; phase-failure protection; undervoltage protection; drain and exhaust when unloading and stopping running the equipment; ensure zero-pressure start; ensure interstage timed drainage when air compressor operates continuously, which effectively prevents water flood and liquid impact.
• There are interstage safety valve and pressure indicator; pressure and temperature measuring interface is available; it is convenient for user to install and debug remote monitoring system.
• Use Shangair patented multi-stage complex impedance suction filter featuring low noise and pollution resistance.
• Advanced inductive low oil level alarm (or forced stoppage) device featuring stable performance and reliability and ensuring that the compressor is free from oil shortage and burn-in failure.
• 5-digit digital counter recording accumulated operation hours of the compressor.
• Service life of plated piston ring is three to four times longer.
• Completely new dynamic balancing design; vibration severity is only one fourth of the internationally advanced level.
