Frequently Asked Questions
Linear slot diffusers are air vent covers that serve as the visible outlet for airflow in a space. They are installed over duct openings to distribute heated or cooled air from an HVAC system into rooms. Air is delivered through the face of the vent, also known as an Air Vent Cover or Linear Slot Diffuser.
First, determine the CFM required for the room where the linear slot diffusers will be installed, and if using multiple diffusers, divide the total CFM accordingly.
Second, choose the diffuser style—single, double, or triple slot—keeping in mind that while single slots offer a slimmer look, they provide lower airflow capacity than 1-slot or 2-slot options.
Third, order the linear slot diffusers and proceed with installation; professional installation is recommended, although it can also be done as a DIY project.
Linear slot diffusers form the visible face of a vent and are commonly known as vent covers. They are valued for their clean, modern appearance that enhances the aesthetic of any room they are installed in.
We recommend measuring the air duct opening to ensure the neck of the AC vent cover will properly fit inside. Our sizing is based on the neck dimensions of the vent cover, not the face size. Below is a quick guide showing what to measure after removing the existing AC vent cover.
At the moment, our AC vent covers are only available in standard ceiling white. We’re able to keep our modern vent covers affordable by manufacturing them in bulk, which is also why we don’t offer custom sizes or additional color options.
Yes, we only offer Plenum Boxes for our Linear Slot Diffusers:
Linear Slot Diffusers - 1 Slot
Linear Slot Diffusers - 2 Slot
They are made of galvanized metal and insulated with a black foam for a superior R rating that is higher than anything in the market.
Yes, our AC vent covers are available in standard ceiling white, but they can also be painted if desired. However, we don’t generally recommend painting them, as they come powder-coated with an electrostatic finish that is durable, easy to clean, and highly resistant to dust. If you do choose to paint them, we suggest using an oil-based paint or epoxy for the best results.
Yes, at the moment we only offer plenum boxes for our Linear Slot Diffusers (1-slot and 2-slot models). We do not provide plenum boxes for standard linear slot diffusers, as retrofit installations typically already include an existing plenum box.
