Industrial airflow verification
Independent on-site airflow measurement, dust collection reviews, and practical reporting for industrial facilities across Southwestern Ontario.
If your facility relies on dust collection, fume extraction, or process exhaust, we help you confirm what the system is actually doing—using clear measurements 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 sign-off.
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, fire risk concerns, chronic plugging, or insurer questions.
Common triggers: odour migration, operator exposure concerns, or “works only when doors are open”.
Common triggers: safety reviews, insurance audits, 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.
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 sign-off 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.
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.
These are common, specific requests we see from industrial facilities. If you have a chronic problem or a new install you want validated, we can scope the right measurement points and produce a report you can hand to operations, EHS, management, insurers, or contractors.
Common triggers: “suction feels weak”, dust escaping, filter plugging, or a system that “never worked right”.
Common triggers: welding fumes, grinding dust, odour complaints, or “it only works when the doors are open”.
Common triggers: doors hard to open, cold drafts, odours, comfort complaints, or backdrafting concerns.
Common triggers: noise, vibration, “it should be stronger”, recent retrofits, or escalating maintenance costs.
Common triggers: new equipment added, new duct runs, collector changeouts, or a project that needs sign-off.
Common triggers: insurer questions, new EHS leadership, corporate audits, or “we need proof”.
Common triggers: chronic complaints, dust escape, inconsistent performance by shift, or a system that has had multiple “fix attempts”.
Common triggers: preventative maintenance programs, corporate EHS requirements, or a desire to reduce surprise failures.
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).
Transparent, scoped work. Prices below are starting estimates only. Final pricing depends on access, number of measurement points, safety requirements, travel, review time, and reporting detail.
Targeted airflow check
From $1,500 estimated starting point
Standard site review
From $4,500 per system or problem area
Follow-up verification
From $2,000 per visit
Larger multi-system reviews, plant-wide verification programs, insurer/EHS documentation packages, or U.S. travel are quoted after scope.
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.
Quick answers to common questions about airflow testing, access, and reporting.
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.
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.

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.
Tell us what you want verified and where. This can be a targeted check for one weak branch, hood, fan, or collector connection, 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.
