As a purchasing manager in the USA manufacturing sector, you face mounting pressure from high energy bills, OSHA fines, and production halts. Poor make up air leads to negative pressure, pulling in contaminants and disrupting operations.
Exhaust fans without proper make up air fans create imbalances, forcing HVAC systems to overwork. Fact: Facilities report 25-40% higher energy costs per EPA data.
Inadequate fresh air supply exposes teams to fumes and dust. In 2025, USA fines for ventilation violations hit $1.2M industry-wide (OSHA reports).
Unbalanced air pulls in corrosives, damaging machinery. Scenario: A Midwest factory lost 15% productivity to premature wear.
Standard metal fans corrode in harsh environments, failing quickly. Your ROI suffers from frequent replacements.
