Environmental protection standard of air compressor

Analysis of Environmental Protection Standards for Air Compressors: Guidelines for Compliance and Green Development

air compressor environmental standards focus energy efficiency, noise, emissions and resource recycling, mainly covers the following requirements:

1. energy Efficiency Standards
   • european Union: The ERP directive requires air compressor energy efficiency ratio (EER)≥ 7.0 (from 2021) to promote the popularization of IE4 ultra-efficient motors.
   • China: GB 19153-2009 stipulates the energy efficiency limit value of small air compressor and eliminates high energy-consuming equipment.
2. Noise control
   • international Standards ISO 2151 specifies noise limits for industrial equipment, and some areas are required to be ≤ 75dB(A)(1 meter distance).
   • China: GB 3811-2008 Compulsory air compressor noise ≤ 85dB(A), lower around hospitals and schools.
3. Emissions and Oil Pollution
   • oil-free technology: ISO 8573-1 Class 0 certification ensures zero oil content in compressed air, suitable for pharmaceutical, electronics and other industries.
   • Exhaust gas treatment: EU ATEX directive limits the emission of explosive gases and requires a filter.
4. Environmental certification and trends
   • international Certification: CE (EU Safety and Environmental Protection) and Energy Star (US Energy Star) marks have become the procurement threshold.
   • Green Design: Using frequency conversion control and waste heat recovery technology to reduce carbon emissions and meet the goal of carbon neutrality.

Shopping recommendations: Oil-free variable frequency air compressors certified by ISO 8573 and ERP are preferred to regularly detect noise and energy efficiency and meet the upgrading requirements of environmental protection regulations.
