PROJECT-CONFIGURED EXHAUST & MAKE-UP AIR

Commercial Compensating-Air Exhaust Hood

SourcePro coordinates compensating-air exhaust hood systems around the required exhaust volume, replacement-air strategy, room pressure, outdoor conditions, capture zone and kitchen comfort. Front, rear or split supply-air arrangements can be reviewed together with the hood, fan, controls and optional air treatment.

Overview

Product Overview

Removing kitchen exhaust without a planned replacement-air path can create negative pressure, unstable capture, door problems and uncomfortable drafts. A compensating-air hood therefore needs both exhaust and supply design. The supply location, discharge velocity, air temperature, interlocks, building HVAC and appliance plume must be assessed together rather than applying a universal supply-air percentage.

Commercial Compensating-Air Exhaust Hood FAQ

What is a compensating-air exhaust hood?

It is a kitchen exhaust hood coordinated with a controlled replacement-air path, such as a front, back or split supply plenum, to support capture and room-pressure balance.

How much make-up air should be supplied through the hood?

There is no universal percentage. The quantity and discharge pattern depend on exhaust volume, room HVAC, outdoor conditions, capture stability, comfort and local requirements.

Can the make-up air be heated or cooled?

Yes. Tempered make-up air can be reviewed using a dedicated unit or building system. Heating or cooling duty and controls are calculated for the project.
