Envisivent Permanent Flush Mount Air Return — 8" x 8" (Drywall Opening)

Envisivent Permanent Flush Mount Air Return creates a seamless, mud-in return that finishes perfectly level with drywall for a quiet, architectural look. Sized for an 8" × 8" drywall opening, the face vanishes once taped, mudded, and painted—no frames, no visible screws—so walls read clean and intentional across design-first residential and commercial interiors.

This paint-ready return ships primed and installs with standard tape, mud, and sand steps in 1/2" or 5/8" gypsum. The slotted cover is manufactured from triple-fiber reinforced cement board and nests in a galvanized steel frame for stability at the perimeter. Finish on site to match wall color and sheen so the grille recedes into the architecture while maintaining low-velocity return airflow. Plan framing square and true, keep compound out of the slot field, and coordinate filter access within the HVAC design. This is a permanent mud-in detail; choose Envisivent’s removable series if routine behind-grille access is required. Key specs (concise): installs in an 8" × 8" drywall opening; paint-ready cement-board face with galvanized frame; compatible with 1/2" or 5/8" drywall; interior wall use; horizontal or vertical slot orientation during install.
