How to Ensure Your Property Is Protected

What is a door fan test? Do you need one? We answer these and other commonly asked questions about industrial air testing below.

Q: What is a door fan test?

A: A way to measure the leakage of an enclosure using a large, calibrated fan temporarily installed in a doorway of the room or building to be tested, and a pressure-sensing device to measure the pressure created by the fan flow.

Q: Who needs to have a door fan test?

A: There are many reasons to consider having a door fan test conducted in an industrial setting. The first is if you are having a clean agent fire suppression system installed somewhere on-site. Not only is it important to know if the air leakage is low enough to have a sufficient hold time for the clean agent after discharge, it is also important to know whether a pressure relief vent is needed and, if so, what size.

The next reason is for mandated shelters-in-place. Whether federally or company mandated, shelters-in-place should be taken very seriously as the health and safety of your workers may be on the line. The only certain way to determine if your shelter-in-place facility is airtight is by administering a door fan test.

There are many other reasons, including determining the energy efficiency/cost savings of a structure and deciding how much sealing needs to be done to ensure a structure is free of dust, mold and unwanted insects and vermin.
