6. Energy and Environmental Protection
   • sewage treatment: Drive air flotation equipment to separate suspended solids in sewage through high-pressure bubbles.
   • Gas transportation: In natural gas filling stations, compressed air is used to drive gas pumps and valve controls.

2. technical advantages and applicable scenarios

1. high efficiency and energy saving
   • permanent magnet synchronous motor: The efficiency is 3%-5% higher than that of traditional asynchronous motors, reducing power loss.
   • variable frequency speed regulation: Automatically adjust the speed according to the gas consumption to avoid no-load operation, and the comprehensive energy saving is more than 30%.
   • Applicable Scenarios production lines with large fluctuations in gas consumption (e. g., electronics plants with intermittent production), factories with 24-hour continuous operation (e. g., food plants).
2. Stable output
   • screw compression structure: No reciprocating motion, small vibration, low noise (usually ≤ 75dB), stable output pressure.
   • Applicable Scenarios: Processes sensitive to air pressure fluctuations (such as semiconductor lithography, precision spraying).
3. Low maintenance costs
   • oil-free design avoid oil pollution, reduce filter replacement frequency and maintenance time.
   • Long life parts: Permanent magnet motor and screw rotor life of more than 10 years, reducing replacement costs.
   • Applicable Scenarios: Scenarios requiring long-term stable operation and limited maintenance manpower (e. g. mines in remote areas, overseas factories).
4. intelligent control
   • inverter integration support remote monitoring, fault warning and automatic start-stop, unattended operation.
   • Applicable Scenarios: highly automated factories (e. g., intelligent warehousing, unmanned workshops).
