Q: What is the purpose of a make-up air kit for a range hood?
A: A make-up air kit for a range hood replaces the air that is removed from the kitchen during ventilation. It improves indoor air quality and range hood performance by equalizing the air pressure, thus increasing the efficiency of the range hood.
Q: What are the consequences of not having a make-up air kit in a kitchen ventilation system?
A: Without a make-up air kit, the kitchen ventilation system's efficiency decreases as it gradually loses air, leading to negative air pressure. This negative air pressure can cause issues like insufficient ventilation, increased energy consumption, and potential damage to the range hood due to excessive strain.

A: The product category for this make-up air kit is "APPLIANCE". The product subcategory is "PREMIUM MAJOR APPL | SO PAC ACCY BBHD".
A: The minimum ventilation capacity required for a range hood to be compatible with this JennAir make-up air kit is 400 CFM (Cubic Feet per Minute). This information can be found in the "Overview" section of the product description, where it states that the kit "works with hoods that have ventilation greater than 400 CFM".
A: This make-up air kit is compatible with any range hood with ventilation greater than 400 CFM. However, it may not be compatible with all range hood models. To ensure compatibility, it is recommended to check the model number of your range hood against the list of compatible models provided by the manufacturer.
Q: How does a make-up air kit improve the efficiency of a range hood?
A: A make-up air kit improves the efficiency of a range hood by replacing the air removed from the kitchen during ventilation, thus equalizing the air pressure. This prevents the range hood from losing efficiency due to the gradual loss of air within the kitchen.

This duct accessory makes the proper transition when attaching the duct to the discharge opening on the range hood. Please check your Zephyr range hood's specification sheet to ensure compatibility.

10-inch round, universal make-up air damper kit for use with any Zephyr range hood motor operating over 300 CFM and up to 1,200 CFM. When range hoods exhaust air out of your home, negative air pressure is created unless the exhausted air is replaced by fresh outdoor air. Zephyr’s make-up air damper is designed to balance the air pressure in your home by automatically opening to allow fresh air in while the range hood is operating.
