Who this is for

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, airflow balancing support, and a report your team can act on.

Typical industries

  • Metal fabrication, welding, grinding, and cutting
  • Woodworking and engineered wood products
  • Food processing and bulk material handling
  • Plastics, composites, and general manufacturing
If you have airborne dust, fumes, odours, or a process exhaust system, the measurement approach is usually transferable.

Common reasons teams call us

  • “Suction feels weak” or dust/fumes escaping at pickup points
  • Filters plugging frequently or maintenance costs climbing
  • New dust collector or ducting installed—need independent validation
  • After adding equipment/branches, existing pickups underperform
  • Upcoming EHS / insurer review—need organized measurement documentation
If you’re not sure what to measure, we start with a short scope call and a walkdown.

Services

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.

Targeted airflow checks

Simple CFM and static pressure checks for one weak branch, hood, pickup point, fan, or dust collector connection.

Dust collection performance verification

CFM measurements, capture checks, and bottleneck identification to confirm real suction where it matters.

Industrial airflow balancing support

Field measurements to identify uneven suction, restricted branches, poor distribution, and systems that are no longer operating as intended.

Local exhaust ventilation (LEV) testing

Hood airflow and capture effectiveness checks for fume extraction, welding, grinding, and process exhaust.

Make-up air + building pressure balance

Verify supply vs. exhaust, diagnose negative pressure issues, and document practical corrections.

Fan & blower performance verification

Confirm operating point vs fan curve using measured airflow and static pressure—especially after complaints or retrofits.

Post-install / post-modification validation

Independent airflow verification documentation after new ducting, new branches, collector changeouts, or equipment additions.

Ventilation troubleshooting (root cause)

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.

Targeted airflow checks for plant problems

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.

Single branch or pickup point

For weak suction at one machine, hood, duct branch, drop, or pickup point.

  • Pitot tube CFM check where access allows
  • Static pressure reading and access notes
  • Short photo-backed findings summary

Dust collector suction check

For plants trying to determine whether the issue is at the collector, filters, fan, ducting, or a specific branch.

  • Collector/fan observations
  • Branch or main duct readings where practical
  • Likely bottlenecks and practical next steps

Before / after verification

For maintenance changes such as filter replacement, duct cleaning, fan repair, damper changes, or branch modifications.

  • Baseline and follow-up readings where available
  • Simple comparison table
  • Short addendum for internal records

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.

Method

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

  • Define measurement points and access constraints
  • On-site verification and documentation
  • Compute airflow from measured velocity data
  • Summarize findings with context and assumptions

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.

FAQ

Quick answers to common questions about airflow testing, access, and reporting.

What standards do you follow? practical field measurement

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.

Do you provide design or sell equipment? independent

No. We focus on measurement, verification, and clear documentation. Recommendations are scoped and prioritized, but we don't sell equipment or work on commission.

Is this a certified TAB or compliance report? scope limits

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.

Can you just check one duct branch or hood? yes — small scopes welcome

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.

Do you work with our contractor or engineering firm? independent verification

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.

Where do you work? Southwestern Ontario + USA case-by-case

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.

What do you need from us to start? scope call

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.

How long does a typical site take? 1–3 days typical

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.
