Plenum in heating, ventilation, and air conditioning (HVAC) systems is a box that connects to the HVAC system. It has a critical function and that is to bring in distribute and remove air.

Introduction: Correct selection and sizing of distribution plenum chambers is critical because terminal air resistance is very low relative to the distribution duct-work resistance. It is therefore recommended that whenever possible terminals are served by low velocity stub ducts from branch ducting systems fitted with correct balancing controls. 

Installation: The plenum boxes and neck reducers are supported by 4 drop rods through a locating hole positioned near each corner. When ordering plenum chambers please specify length width & height, spigot size and position (top or side entry) and control options. Please note that the plenum height should in general be 100mm greater that the spigot diameter (side entry applications).
