## Description

BUILDMART - 24" Linear Slot Diffuser - (1 Slot) Single Slot - White Decorative Air Vent - Modern AC Vent Cover for Ceiling, Walls & Floors - Texas - desertcart.com

Review: Looks sleek - I needed a clean looking vent for heat exhaust on the base of my under-counter microwave/convection oven. My cabinet guy cut an opening in my toe kick to fit this in. It is sleek & modern looking. Very well made. The vents inside are black & can be closed or opened. It isn't cheap but it's worth what it costs. I ordered 3 different vents & this one looked the best.
Review: Makeup Air Is A Must - I purchased and used one of these for a makeup air system on our stove top vent. the 24", single slot air vent fit perfectly under the cabinet kick panel and supplies just enough makeup air when the stove top vent is on. We have a damper controlled fresh air inlet under the house, in the crawl space that brings in fresh makeup air, via motorized damper that opens when ever the powerful exhaust vent is on. Works with the plenum we purchased for the 24" single slot air vent that has an 8" opening for duct work. We can have a fire in our living room fireplace and cook with the exhaust vent on at the same time, no issues. Works as I designed it to work. Every 300 cfm or over exhaust fans MUST have makeup air of some sorts or they will cause combustion issues and negative pressure in your house. Locating our makeup air just below the stove top burner ensure makeup air coming in goes directly up and out with the exhaust vented air.

## Features

- Commercial grade solid aluminum with modern architectural design for ceilings, walls, and floors. This vent cover was designed to be decorative and not structural. You can use this as a floor vent cover, but it is not designed to support weight, adding any type of weight is not recommended. This model can be used as a supply vent cover and return vent cover - This is a non-filter model
- Cfm: 151 ft3/min - effective velocity: 9.8 ft/s; neck: 23 3/4" x 1 5/8" - face: 25 1/16" x 3 1/16" (The neck is the section that goes into the vent hole while the face is what will actually cover)
- Designed to elevate any space, our modern AC vent covers are perfect for bathrooms, kitchens, living rooms, offices, and commercial settings. Whether you're remodeling or upgrading, they add sleek, architectural value to walls, ceilings, and floors.
- *This is a design and utility patent pending product* We make sizes from 12" to 72" linear slot diffuser ac vent covers for the modern day home
- We have over 70 standard vent cover sizes to replace your traditional looking grills. We also have over 40 linear slot diffuser sizes with their matching plenum box. All models are in stock ready to ship in both white and black colors – Our models are also paintable.
- All vent cover sizes can be used as both supply and return grilles. Currently our decorative air vent covers are non-filtered models. This will work perfectly if you have your filter in the machine.
- A standard linear slot diffuser is a modern looking decorative air vent cover that fits on a traditional air exit and replaces the traditional looking grills. They have a beautiful linear slot diffuser; they are easy to replace since it is retrofit to the traditional vent cover sizes. Enjoy the incredible looks, the durability since it is 100% aluminum, and they are also very easy to clean. A linear slot diffuser is a linear air exit or vent cover with a long linear look that you usually find in hotels and modern houses. The standard linear slot diffusers and the linear slot diffusers can both be used for remodels and new construction.
- The size that you need to know to buy this vent cover, or any other vent cover is by measuring the air duct opening (the plenum box opening) and not the face size or the vent cover. We recommend you remove the old air vent cover and measure the size of the air duct opening. You do not need to take into consideration the face size of the vent cover. The important measurement is the interior duct opening size. Example: A traditional vent cover size can have a face size of 14x8, and neck of a little less than a 12x6. Your air duct opening should measure 12x6, so you purchase a 12x6. Vent cover dimensions are categorized by the neck and not by the face of the air vent cover.
- The method of installation of our modern air ac vent cover is hidden through the pre-drilled holes inside of the diffuser, which can be accessed by opening the dampers and using a drill with a six-inch extension to screw it into place. Please find attached our instructional videos. This way we avoid having a front drill screw and ruin the esthetics of the product.
