Make-Up Air & Building Pressure Checks

Independent airflow measurement and reporting services for industrial facilities across Southwestern Ontario. We focus on practical field measurements, clear documentation, and next-step 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, building pressure relationships, and make-up air interaction — separating guesswork from measurable facts.

What We Measure

• Supply and exhaust airflow at selected ducts, branches, hoods, or test locations
• Static pressure and pressure relationships across the system
• Building pressure symptoms such as drafts, door pressure, and air migration
• Make-up air interaction with process exhaust, dust collection, or ventilation systems
• Operating point relative to fan curve where available

Common Triggers

• Door pressure, drafts, cold air infiltration, or air migration complaints
• Exhaust systems that appear to overpower available make-up air
• Dust, fumes, odours, or heat moving into unintended areas
• Post-install airflow verification after duct, fan, or ventilation changes
• Documentation for maintenance, EHS, insurer, or contractor discussions

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, process exhaust, or make-up air, independent airflow measurement can provide clarity.

Our Approach

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