Exhaust fan FLX-PLO series

plenum

FLX-PLO plenum boxes and distribution boxes are connecting pieces for FLX-HDPE and FLX-HDPE-A semi-rigid, non-metallic ducts, which form an air distribution system for mechanical ventilation systems with heat recovery. Due to small size, plenum boxes do not require a lot of space or special installation. This allows to save more usable interior space. FLX-PLO Plenum boxes have factory-fitted EPDM rubber seals mounted on connection spigots. Plenum boxes have duct connection spigots in 75mm or 90mm diameters that are used to connect with FLX-HDPE-75 or HDPE-A-75 semi-rigid ducting - as well as on male duct connection spigots which connect a plenum box to a SPIRAL duct. It is possible to order insulated plenum boxes - product code FLX-PRI, the plenum boxes are insulated with technical insulation with a thickness of 9mm.
