The Evolution of Make-up Air Delivery

The Evolution of Make-up Air Delivery

The Perforated Supply Plenum (PSP) and AC Perforated Supply Plenum (AC-PSP) both introduce make-up air near the hood and direct air downward into the capture area of the hood. The dual plenum design (AC-PSP) adds an additional plenum to allow convenient termination of the HVAC ductwork to the kitchen and provide spot cooling. Providing the required make-up air for your kitchen system, the PSP and AC-PSP both evenly distribute air along the length of the hood through the perforated stainless steel diffuser plates.
