What to Expect from an Industrial Indoor Air Quality Survey [VIDEO]

Transcript

After 淫乱社区 gets on site, we take a lot of different聽air readings and evaluate the the dust collection unit itself for wear and tear, the fan. So when we get聽back to the office we put together a pretty nice report basically laying out everything that we’ve聽seen on site. You know, giving you back all the data on your equipment so if your dust collection聽system has 20 points we basically give you a nice chart back that shows each point, what it goes to,聽the volume that it has, the static pressure at each point. Some indication on whether or not it’s doing聽its job and picking up the the particulate. So we give you all the basic information of what you聽have.

And then once we get through that we give you a section of recommendations pointing out all the improvements that could be made or we’re just generally stating that what you have is good, the design is acceptable and the volume is adequate what those are, we’ll actually go back through and say okay, these were the recommendations for this dust collector. We’ll put together an actual proposal on the cost to do that.

Being that we are a turnkey company we’ll put together a conceptual design, a price for it and then upon acceptance we would give you a final design deliverable along with an implemented solution.

Why Conduct an Industrial Ventilation Analysis

In an industrial ventilation analysis, we conduct an air quality survey by taking air readings of the ventilation system, as well as evaluate the dust collector, fans and all system components. From there, we develop a baseline rating of the entire system鈥攁 useful tool in determining what may need to be done, or not done, with your dust collection system. If you鈥檙e unsure whether an engineering study is right for you, here are the primary reasons to request an analysis.

Reason #1: Adding equipment

When adding equipment, you may need to expand the ventilation system. The best way forward is to start by evaluating the current system and its capacity. With that knowledge, you鈥檒l then know whether your current system can handle more volume and how that may affect the collection volume from other equipment.

Also, adding equipment doesn鈥檛 automatically mean you need to add to your ventilation system. A ventilation analysis may show that you already have excess capacity. We may also be able to redesign the system to keep you from rerouting ductwork or buying a new dust collector.

Reason #2: Changing a manufacturing process

A manufacturing process change may mean greater particulate volume being directed to an area not equipped to handle the excess. If gone unchecked, particulate can build up in the ductwork, adding weight that can cause the duct to fail. And if the duct isn鈥檛 built to carry extra weight, facility damage and employee injuries may occur.

Reason #3: Becoming more energy efficient

Many companies are looking to be more environmentally conscious by using less energy. Even though an older dust collection system continues to do the job well, it may be costing more to run. Older fans, for example, can be a culprit. An engineering survey would show whether you could save energy and money with newer, more efficient equipment, depending upon your system design and layout.

Reason #4: Becoming silica standard-compliant

The silica standard is a high bar. If silica is part of your manufacturing process and you are having difficulty meeting the standard, there are a couple of things you should do. First, hire an industrial hygienist who will analyze your facility for silica risk. For example, the hygienist will take samples for every employee in every area of your plant for every shift. Once you have that information, we can then conduct an engineering study to review your entire system and determine how best to capture the silica.

What to Expect When Your Industrial Ventilation Analysis is Complete

Once we take the air quality survey readings and inspect your system, we develop a comprehensive written report of our findings. You鈥檒l receive data on your equipment and ventilation system with indication of whether it鈥檚 collecting particulate effectively and where improvements, if any, are needed. We then:

• Request a follow-up meeting to discuss areas that need improvement
• Develop a conceptual design
• Develop a proposal that includes our costs based on our design
• Once agreed upon, implement the solutions

Getting an engineering study done is much like going to the doctor鈥攊t helps ensure everything is operating the way it should. If you believe an industrial ventilation analysis would benefit your company, contact us to schedule a survey.

The importance of optimal industrial airflow

Proper airflow is an important element of any dust collection system. Benefits include:

• Extended dust collection filter life
• Increased energy savings
• Reduced maintenance and replacement costs
• Better overall fume and dust collection

Risks of poor airflow

The consequences of improper airflow and system maintenance include:

• Too much airflow can pull valuable product out of the process and into the waste stream.
• Too high transport velocity can increase wear on ductwork.
• Too little airflow can allow dust to escape the process and increase the dust hazards in the facility.
• Poor duct routing or low transport velocities can cause dust and particulates to settle in ductwork.

Proper industrial airflow requires a balanced approach. Optimization keeps a facility, people and equipment working at peak performance.

Techniques to maintain proper industrial airflow

Manually adjust the industrial fan鈥檚 outlet damper, inlet damper or variable frequency drive:

If the fan鈥檚 outlet damper, inlet damper or variable frequency drive (VFD) is adjusted properly, airflow can be controlled.  If done improperly, this adjustment can create a shorter filter life, product quality issues and increased operating costs.

Best practice: Monitor differential pressure readings regularly. Once an initial air reading is complete and it is known how the system should operate – a differential pressure benchmark can be set and the operators will be able to easily see when the system is not operating within acceptable limits.

Manually adjust the industrial fan鈥檚 inlet damper or blast gates at collection points:

Making sure airflow is balanced is a critical maintenance step.

Best practice: Keep an eye on airflow. Settling dust could indicate slow airflow. Wear spots could indicate high airflow.
