Industrial airflow verification
Independent on-site airflow measurement, balancing support, dust collection reviews, and practical reporting for industrial facilities across Southwestern Ontario.
Email a few photos, symptoms, or system details and we’ll point you in the right direction.
info@industrialairflowverification.comIf your facility relies on dust collection, fume extraction, or process exhaust, we help you confirm what the system is actually doing—using clear measurements, airflow balancing support, and a report your team can act on.
We work across the major industrial sectors in Southwestern Ontario. Below are common facility types where dust collection, local exhaust ventilation (LEV), make-up air balance, and fan performance verification are frequently needed.
Common triggers: line expansions, “weak suction” complaints, corporate EHS audits, or project close-out documentation.
Common triggers: filters plugging, new machines added, nuisance dust, or inspector documentation requests.
Common triggers: audit preparation, odour complaints, “doors won’t close”, or expansion without rebalancing airflow.
Common triggers: housekeeping burden, housekeeping, dust accumulation, plugging, or insurer documentation concerns, chronic plugging, or insurer questions.
Common triggers: odour migration, operator exposure concerns, or “works only when doors are open”.
Common triggers: EHS reviews, insurance documentation requests, process changes, or odour/exposure issues.
Common triggers: visible dust during transfer, cleanup burden, or upcoming risk reviews.
Common triggers: new equipment installs, comfort complaints, or energy penalties from imbalance.
Common triggers: “system should be stronger”, noise/vibration complaints, or contractor dispute resolution.
Common triggers: odour migration, pressure complaints, safety audits, or facility expansions.
Not sure where your facility fits? If you have airborne dust, fumes, odours, or process exhaust—our measurement approach is usually transferable.
Measurement and reporting first, with a light touch of consulting—focused on practical next steps. Scope can be as targeted as one weak branch, hood, fan, or dust collector connection, or as broad as a full site review. We’re not a contractor and we’re not commission-driven.
Simple CFM and static pressure checks for one weak branch, hood, pickup point, fan, or dust collector connection.
CFM measurements, capture checks, and bottleneck identification to confirm real suction where it matters.
Field measurements to identify uneven suction, restricted branches, poor distribution, and systems that are no longer operating as intended.
Hood airflow and capture effectiveness checks for fume extraction, welding, grinding, and process exhaust.
Verify supply vs. exhaust, diagnose negative pressure issues, and document practical corrections.
Confirm operating point vs fan curve using measured airflow and static pressure—especially after complaints or retrofits.
Independent airflow verification documentation after new ducting, new branches, collector changeouts, or equipment additions.
When “it never worked right”—measure, isolate causes, and prioritize fixes without upsell pressure.
Want a clearer list of examples? See What we verify. For balancing-specific work, see industrial airflow balancing, dust collection system balancing, and plant ventilation airflow balancing.
Many airflow issues start with a simple question: is this branch, hood, fan, or dust collector connection actually moving enough air? For those cases, we can perform a focused check and provide practical documentation without turning it into a large engineering study.
For weak suction at one machine, hood, duct branch, drop, or pickup point.
For plants trying to determine whether the issue is at the collector, filters, fan, ducting, or a specific branch.
For maintenance changes such as filter replacement, duct cleaning, fan repair, damper changes, or branch modifications.
Pricing is estimate-based. Final scope depends on travel, site access, number of measurement points, safety requirements, and reporting/review time. Test holes can typically be capped after measurement where appropriate.
Independent field verification
We measure the parts of an industrial airflow system that determine whether it is actually performing: capture points, branches, mains, fans, collectors, make-up air, and building pressure. The result is a clear record your operations, EHS, maintenance, management, insurer, or contractor can use.
CFM • Capture • Balance
Common triggers: weak suction, dust escape, filter plugging, or a system that never worked as expected.
Hood airflow • Capture effectiveness
Common triggers: welding fumes, grinding dust, odour complaints, or capture that changes when doors open.
Supply • Exhaust • Pressure
Common triggers: hard-to-open doors, cold drafts, odour migration, comfort complaints, or pressure concerns.
Static pressure • Operating point
Common triggers: noise, vibration, weak performance, recent retrofits, or rising maintenance costs.
Commissioning • Close-out • Records
Common triggers: capital projects, contractor close-out, insurer requests, corporate audits, or a need for proof.
Measure • Isolate • Trend
Common triggers: chronic complaints, inconsistent performance, repeated failed fixes, or preventative maintenance programs.
Typical applications
Metal fabrication, woodworking, food processing, bulk material handling, plastics, composites, general manufacturing, and other facilities with dust, fumes, odours, or process exhaust.
Helpful before the visit
Drawings, fan information, photos, problem locations, operating schedules, and site-access requirements all help—but many projects still begin with a simple scope call and walkdown.
We use established field measurement practices. A typical airflow verification uses a pitot tube and a measured traverse to estimate velocity profile and calculate flow.
How it works
A note on technical detail
We keep the report content as simple as possible. The report includes the technical detail needed for decision-making (measurement points, assumptions, and calculation basis), without turning into a textbook.
Designed to be readable, specific, and defensible.
Results by measurement point, with any constraints clearly stated.
Observed issues that explain performance, prioritized by impact.
Recommendations with scope clarity (what to try first, and why).
Most projects are quoted after a short scope review. The right price depends on the number of systems or measurement points, site access, safety requirements, travel, production constraints, and the level of reporting needed.
Targeted airflow check
System review
Follow-up verification
A clear quote is provided before work begins. Larger multi-system reviews, plant-wide verification programs, insurer/EHS documentation packages, or U.S. travel are scoped individually.
Primary service area is Southwestern Ontario. Travel elsewhere in Ontario and into the United States may be available on a case-by-case basis depending on scope and schedule.
We can support U.S. sites when it makes sense (for example: multi-site programs, repeat clients, or projects near the border). We'll confirm feasibility during the scope call.
Answers before the site visit
Straight answers about measurement methods, scope limits, access, reporting, and how a typical project starts.
We use established field measurement practices (pitot tube traverses, static pressure readings, and clearly documented assumptions). If you have an internal standard or a project spec, we align the report format and measurement plan to it.
No. We focus on measurement, verification, and clear documentation. Recommendations are scoped and prioritized, but we don't sell equipment or work on commission.
No. Reports are intended for practical airflow verification, troubleshooting, and maintenance planning. They are not a substitute for certified TAB reports, engineered system design, Pre-Start Health and Safety Reviews, code compliance reviews, combustible dust hazard analysis, occupational hygiene exposure assessments, or equipment manufacturer inspections where those services are required.
Yes. Many projects are focused checks for one weak suction point, hood, duct branch, fan, or dust collector connection. If access allows, we can measure airflow, document the result, cap the test opening where appropriate, and provide a short written summary.
Yes. We can coordinate measurement points and reporting needs with your contractor or engineer, while remaining vendor-neutral. Many clients use our report to validate work and close out projects with clear documentation.
Our primary service area is Southwestern Ontario. Travel elsewhere in Ontario and into the United States may be available on a case-by-case basis depending on scope and schedule.
A short call to understand the problem, followed by a quick list of measurement points and access constraints. Drawings and fan info help, but many projects begin with a walkdown.
Many sites can be measured in a day with reporting shortly after. Larger facilities or complex systems may require multiple days. We'll quote based on access, number of systems, and travel.
Still not sure?
We can usually tell you what information would be useful before a formal quote.
Tell us what you want verified, balanced, or documented and where. This can be a targeted check for one weak branch, hood, fan, or collector connection, airflow balancing support across a dust collection or ventilation system, or a broader site review. We’ll respond with a scoped plan and a clear estimated price. Primary service area is Southwestern Ontario; U.S. travel may be available on a case-by-case basis.
