Why Air Compressor Classification Matters
Industrial operations lose $3.2 billion annually (U.S. DOE data) through improper compressed air system design. Selecting the correct compressor type can yield:
✔️ 35%+ energy cost reduction
✔️ 50% longer equipment lifespan
✔️ 90% improved process reliability
