Make-Up Air Service
Every cubic foot of air your exhaust hood removes must be replaced — otherwise negative pressure builds, smoke rolls into the dining room, and doors become difficult to open. Hood Builder offers a complete line of indoor and outdoor make-up air units for commercial kitchens. Our systems deliver evenly tempered replacement air, heated by direct gas flame when required, so your kitchen stays balanced and comfortable.
Make-up air configurations are available for:
- High-heat grease-generating cooking equipment (Type I hoods)
- Steam and heat-only equipment (Type II hoods)
- High-volume operations requiring thousands of CFM of replacement air
