Make-Up Air & Building Pressure Balance Testing

Independent airflow measurement and reporting services for industrial facilities across Southwestern Ontario. We focus on defensible field measurements, clear documentation, and practical recommendations — not equipment sales.

Why This Service Matters

Airflow systems drift over time. Filters load, ductwork changes, equipment is added, and performance rarely matches assumptions. Objective field measurement clarifies actual airflow, static pressure, and capture performance — separating guesswork from measurable facts.

What We Measure

• Branch and main duct airflow (CFM)
• Static pressure and system resistance
• Hood capture effectiveness
• Transport velocity and settling risk
• Operating point relative to fan curve (where available)

Common Triggers

• “Suction feels weak” complaints
• Dust or fumes escaping at pickup points
• Frequent filter plugging or rising maintenance cost
• Post-install validation after duct modifications
• Audit or insurer documentation requirements

Industries We Support

Metal fabrication, automotive suppliers, woodworking, food processing, plastics, bulk material handling, and general manufacturing facilities across Ontario. If your facility relies on dust collection, local exhaust ventilation, or process exhaust, independent verification provides clarity.

Our Approach

We define measurement points, perform on-site verification, compute airflow using established field methods (including pitot tube traverses), and deliver a concise report outlining findings, constraints, and prioritized next steps.

Serving Southwestern Ontario
