Pluggit presents PluggPlan, a new ventilation system developed specifically for multistory buildings, for new constructions or renovations. PluggPlan is designed for small and medium sized living spaces, with 3 rooms from which to extract the exhaust air (kitchen, bathroom and toilet). The air handling unit PluggPlan is extremely flat, that allows the unit to be installed below the ceiling or above the toilet in a front-wall installation.
