Airboot / SUPPLY Plenum Box (for Panasonic S-125PE3R / S-140PE3R / S-160PE3R) — 345×1035×30 / 2×Ø300 Internal Insulation

Description
The supply airboot (plenum box), model PSPB345/300, measures 345×1035×30 / 2×Ø300 and is internally lined with 5mm insulation. Designed for Panasonic S-125PE3R, S-140PE3R, and S-160PE3R ducted units, this plenum box functions as a static pressure chamber, ensuring smooth airflow transition from the unit’s supply opening to the duct system. By stabilizing static pressure and reducing turbulence, it provides even air distribution, minimizes noise, and improves overall energy efficiency.
