Tate introduced AirArrest, a through-wall wire sealing solution for data centers, office buildings, and other structures that feature raised access floors with underfloor air distribution (UFAD). Designed to seal cable and wire access holes, AirArrest uses patent-pending brush technology to prevent leakage of pressurized air around power and data cables that pass from room to room via through-wall cut-outs. AirArrest takes underfloor air distribution to new levels of flexibility while still maintaining plenum integrity. This unique sealing solution leverages the use of thousands of polygonal shaped filaments that nest together with little or no interstitial space. The edges of the filaments prevent them from moving past one another, thereby eliminating gaps that allow air leakage.
