MERV Rating

different air filters

One common term used when discussing air filtration is the MERV rating. Take a moment to understand what MERV ratings are, and how they applied to your application. Before delving in, it helps to know that  MERV is an acronym for Minimum Efficiency Reporting Value, and it is a standard scale used to rate the effectiveness of air filters in terms of filtering particulate from the air. MERV Scale The American Society of Heating, Refrigeration…

Mechanisms Of Filtration

filtration mechanisms

Need a brief overview of the basic five air filtration mechanisms that are used to remove particulates from the air? Then this is for you. This particular overview is tailored to mechanisms utilized on systems manufactured by Air Quality Engineering. Each air filtration mechanism, including straining, interception, diffusion, inertial impaction and electrostatic attraction, is employed to capture specific range of sizes of the particulate being filtered. The straining, interception, diffusion, and inertial impaction mechanisms rely…

Troubleshooting An Electrostatic Cell

large MistBuster cells

If you know what to look for when troubleshooting an electrostatic cell it is a fairly easy process. I will go over the general troubleshooting of an electrostatic cell in this blog, and this covers all electrostatic cells we sell. If your electrostatic cell has not been cleaned for a while, it is important that the electrostatic cell is thoroughly cleaned before troubleshooting. You can find additional information on cleaning an electrostatic cell here. Notice:…

Isolation, Source, and Ambient Capture

MistBuster on machine tool enclosure

A common question comes up very frequently, and that is “how do you determine if you should do source capture or ambient capture?” Well, the simple answer is you should do source capture; however it is not always convenient or possible to do source capture. What I am going to talk about is the pros and cons of doing isolation, source, and ambient capture. Yes, I just threw isolation capture in there. A lot of…

Kitchen Exhaust PCU Efficiency

AutoClean unit

When sizing a kitchen exhaust pollution control unit, we typically recommend about 2,000 CFM per full size industrial electrostatic cell. Then to achieve higher airflows, we will add more cells in various configurations to maintain 2,000 CFM or less per cell. If you look at the single cell efficiencies graph below, you can see efficiencies graphed for several airflows. If a higher efficiency is required, we will recommend a lower CFM per electrostatic cell to…

MistBuster® Motorized Impeller Change

new MistBuster impeller

We are excited to announce that we have changed the motorized impellers in our MistBuster® line to a new design that significantly improves performance while also improving efficiency. The new motorized impeller has a single piece PA plastic injected impeller compared to our original impeller that was assembled from several pieces of cut and formed pieces of metal. The benefit of the single piece impeller is the ability to have an innovative design that was…

MistBuster® Advantage

Pressure Drop Chart

A frequently asked question when evaluating mist collection solutions is, “what are the advantages of an electrostatic precipitator (like the MistBuster®) over a media air cleaner?” The primary advantages are: airflow, maintenance, and efficiency. AIRFLOW: An electrostatic precipitator stays consistent as the electronic filters (cells) collect contaminant. The reason being that air flow through a cell is not impeded as it collects mist and smoke particulate. The cell design is such that it collects particulates…

MistBuster Oil Selector Switch

Mistbuster 2000 coolant selector-knob

Our patented water/oil selector switch is one feature that makes our mist collector units stand out from the other electrostatic mist collection units on the market. Water soluble coolant has an increased conductivity when compared to oil-based coolant. The patented technology of the water/oil selector switch provides the unique ability to adjust the electrical properties of the MistBuster® to match the type of coolant used. Switching the MistBuster® between water and oil mode is simple….

General Guidelines For Canopy Hood Sizing

welder using canopy hood for fumes

Hot Vs. Cold Process Canopy hood design requires different consideration for both hot and cold processes. Hot processes transfer significant heat to the air surrounding the process via conduction and convection mechanisms. In doing so, thermal drafts are present and can cause upward air currents with air velocities up to a few hundred feet per minute. The design of the canopy hood and exhaust rate must account for these thermal drafts during the sizing phase….
