Explosion-Proof Spray Booth Systems: Industry Trends, Technical Solutions & Safety Compliance

1. Industry Insights & Regulatory Drivers

The Chinese gas alarm market reached ¥12 billion ($1.68B) in 2024, with spray booths accounting for 18% of industrial demand. Post-2025 revisions to the Gas Engineering Code will mandate 30% stricter safety standards for Class II explosion-prone zones like spray booths, driving 20% annual market growth.
