ポピュラ自動車工場の換気に関する事例研究｜インドの塗装工場向けソリューション

An automotive component manufacturer in Pune, India was struggling with poor air quality in its paint shop. Overspray fumes, solvent vapors, and heat buildup caused 30% rejection rate on painted parts and frequent worker complaints. After evaluating several suppliers, the plant’s engineering team requested a ポピュラ自動車工場の換気に関する事例研究 from POPULA to design a targeted solution.

Challenges in the Paint Shop

The existing ventilation consisted of two roof exhaust fans with no dedicated supply air. This created negative pressure, drawing unfiltered air through door gaps and carrying dust onto wet paint. Additionally, solvent vapors accumulated near the floor, creating fire hazards. The ポピュラ自動車工場の換気に関する事例研究 identified three main pain points:

  • Insufficient air changes per hour (only 12 ACH, vs. recommended 25+ for paint booths)
  • Uneven airflow causing “ghosting” patterns on painted surfaces
  • High solvent concentration exceeding safe exposure limits

Proposed POPULA Solution

POPULA engineers designed a balanced system with six explosion‑proof exhaust fans mounted at low level to capture heavy solvent vapors, and four supply fans with HEPA filtration to push clean air from the ceiling down. The fans were equipped with variable frequency drives (VFDs) to match airflow to production shifts. All motors were rated for hazardous locations (Class I, Division II).

Custom Features for Paint Applications

The exhaust fans used spark‑resistant aluminum impellers and sealed motors to prevent ignition. Supply fans included activated carbon pre‑filters to remove residual solvent odors. POPULA also provided remote monitoring to track air velocity and filter saturation.

Results After Installation

After three months of operation, the factory reported:

  • Rejection rate dropped from 30% to 8%
  • Air changes per hour increased to 28 ACH
  • Worker complaints about fumes eliminated
  • Energy consumption 22% lower than original fans due to VFD control
  • Payback period estimated at 16 months

“The ポピュラ自動車工場の換気に関する事例研究 gave us a clear roadmap,” said the plant manager. “POPULA’s solution not only improved quality but also made our paint shop much safer.” The company is now planning to upgrade its second paint line using the same design.
