Makeup Air / Make Up Air

On larger kitchen ventilation systems there is a requirement for make up air. A mechanical input system will be required, and should provide a maximum of 85% of the total air extracted.

Make up air can be brought into the kitchen through ceiling grilles or the canopy supply air plenum. This air must be filtered to prevent insects and other particles entering the kitchen.

Our makeup air systems utilise a variable inlet air damper to effectively control the level of positive pressure or uses a variable speed AC inverter to precisely control the fan motor speed in response to the pressure sensor placed in the kitchen.

As the demand for replacement air increases, the make up air unit responds almost immediately by varying the amu fan motor speed. This important option prevents an undesirable positive or negative pressure situation from occurring.
