\"Using
\nUsing Exhaust Hoods or Ducted Fume Hoods<\/a> can lead to a variety of issues that affect the operation and safety of the fume hood. Below are a few common issues or concerns experienced with Exhaust Hoods.<\/p>\n

\u2022\tDuctwork particulate build-up resulting in downtime and costly maintenance procedures (Haugen, 2018)<\/a>
\n\u2022\tSafety concerns associated with ductwork build-up (Haugen, 2018)<\/a>
\n\u2022\tIssues servicing ducting due to particle build-up
\n\u2022\tReduced blower capacity due to build-up
\n\u2022\tHazardous residues left in ductwork
\n\u2022\tChemical fumes deteriorating ductwork structure (Haugen, 2018)<\/a>
\n\u2022\tEnvironmental concerns about contents of exhausted air<\/p>\n

By adding filtration, you can help improve these conditions and reduce Exhaust Hood concerns. Our latest product \u2013 Exhaust Filter Box \u2013 makes adding filtration to any exhaust hood or ducted fume hood setup simple!<\/b><\/p>\n

What is an Exhaust Filter Box?<\/h2>\n
\"Exhaust<\/a>

The Exhaust Filter Box<\/a> mounts on Exhaust Hoods or Ducted Fume Hoods to provide filtration.<\/p><\/div>\n

An Exhaust Filter Box mounts on an existing exhaust hood and connects to the existing ductwork and fan system to provide particulate and\/or chemical filtration. Depending on the application, the Exhaust Filter Box can be fitted with a HEPA\/ASHRAE filter for particulate, Activated Carbon or Specialty-Blended Filter Media for chemical fumes, or a combination of both. The existing exhaust system draws fumes and particulate from under the hood into the filter box reducing the concentration of contaminants in the airflow. The filtered air exits through the unit\u2019s plenum into existing ductwork and is released outside of the facility.

Exhaust Filter Box Flow Rate Testing & Response Curve Graph<\/h2>\n

Our in-house testing department tested the Exhaust Filter Box with different filter combinations and varying motor speeds to provide an expected flow rate and pressure for each filter type. Five readings at different motor speeds were taken for each filter type and interpolated to create a trend line graph or response curve. This graph can be used to compare to your system\u2019s fan curve to help predict the expected flow rate.
