Fresh Air Intake
Make up air units (also referred to Fresh Air Intake Units ) are integral to maintaining good indoor air quality (IAQ). By helping to maintain the proper air pressure balance between rooms, you can keep cooking and cleaning odors from reaching hallways or dining areas. Additionally, make up air units:
Help cost-effectively meet ASHRAE mandated ventilation rates.
Are direct-fired, meaning that 100% of the energy stays indoors.
Eliminate negative pressure to counter act exhaust systems such as cooking hoods.
Get state-of-the-art control to keep your indoor air as fresh as possible. Installed as part of your home’s heating and cooling system, the Aprilaire Ventilation Controller makes decisions regarding when—and how long—to ventilate. It does this through continuous montinoring of indoor relative humdity, outdoor temperature, and user-friendly settings.
