More Rooftop Filtering
The Filter Curb from Thybar (Addison, IL) can add additional filter capacity to a rooftop unit. Advanced laser technology offers the tightest tolerances and superior construction because each curb is custom-manufactured due to the varying specifications of various roof configurations. The Curbs use an all-welded construction, factory-insulated walls, an integral filter rack, and an access door for servicing filters.
