Performing System Audit

Dust Collection System Audits

One of the most important things we have learned over our years in helping people solve their industrial dust collection problems is that many facilities have good dust collection equipment on site but the design and implementation of the equipment results in underperforming systems. Many of our clients want to know why their existing dust collection systems have excess dust generation from pick-up points, experience frequent plugging in the ducts and allow dust buildup in process areas. This is where dust collection system audits come in.

Our customers often ask us to visit their facility to review their current dust collection system(s) and provide a detailed audit and report that measures the current performance, identifies areas that can be improved and provides budgetary estimates for what those improvements will cost. There are many names for this process including: dust collection system audits, baseline assessments of dust collection systems or gap analysis, but the basic goal is the same – to help our customers understand what they have now and how to improve performance going forward.


Dust Collection System Audits Provide: 

• Identification of causes of plugging, excess dusting and dust buildup.
• Recommended solutions for problems discovered.
• Budgetary costs for the required engineering, equipment and installation of the proposed solutions.

When contracted for this service Airdusco EDS will send an experienced engineer to your facility for an in-depth review of your existing dust collection system or systems.

A Typical Site Visit Includes:

• Observation if the dust generating processes and overall system performance.
• Consultation with plant personnel including operators and maintenance to gather a better understanding of objectives and issues.
• Measure and document key system performance data such as:
air flow (CFM), velocity pressure, conveying velocity, static pressure, fan RPM and amp draw etc.
• Gather and document existing equipment nameplate data such as manufacturer, model number, size, capacity, etc.
• Sketch the system layout including line diameters, hoods, branches, elbows, etc.

Following the site visit, we will prepare a comprehensive deliverable package that will include:

• System Flow Diagram
• System Isometric Drawing
• Baseline Performance Report, including:

- Equipment information and condition.
- Dust sources and pick up hood descriptions.
- Airflow, velocity pressure, and static pressure measurements, per industry
- Comparison of actual performance to theoretical design performance
- Observations, evaluations, conclusions, and recommendations
