The FILTERSCAN air-filter-clog detector provides visual, audible, and remote alerts that a filter needs servicing by monitoring changes in differential pressure in an HVAC system. The detector automatically compensates for changes in system blower speed; can be installed upstream, downstream, or differentially across a filter; and works with single-speed, multispeed, and most variable-air-volume systems. It automatically recalibrates each time a clogged air filter is serviced.
Fabric-duct tensioning system
The SkeleCore in-duct cylindrical tensioning system for textile HVAC ductwork has been expanded with the addition of a fabric-tensioning system (FTS).
