It can be difficult to confirm odor levels when digging deep.

While time and preparation go into the design for a particular type of odor, there may be more present. Furthermore, it is important to know the surrounding geography.

For this project, the deep tunneling for the Westside Subway Extension Project was near the La Brea Tar pits where the H2S levels were expected to be very high. Once drilling began, they experienced other noxious odors that needed to be removed from the air.

Matrix Filter:

Carbon based adsorbent media matrix blocks are aligned and encased in the recycled frame and screen to be installed into various filtration systems to provide the superior performance of PureAir’s adsorbent media. The matrix blocks have a monolithic structure and can be made of either PureAir AC-X, Ammoniasorb®, or Sulphasorb™ chemical adsorbent media. The size and shape of the monolithic structure of the cells leads to turbulent flow and superior performance. The system also has no bypass and a very low pressure drop which amount to total air filtration with efficient energy use.
