Lowell MVB Series Magnetic Vent Blockers for LER Rack | 27"D

AV integrators and system installers managing heat in enclosed rack environments need reliable passive barriers to guide airflow where active cooling can do its job. Lowell's MVB Series magnetic vent blockers are designed to work alongside fan panels, sealing off unmanaged vent openings at the top front, sides, and top of the rear door so that air is pushed through the intended path rather than escaping through gaps. The result is more effective cooling with the fan hardware already in the rack.

These panels are sized for use with LGR, LER, LWBR, and LWR Series racks, and are available in depths to match your installed rack. The magnetic backing allows field placement and repositioning without tools or fasteners, making them practical during both initial build-out and later reconfiguration. Some field trimming may be required to fit specific vent openings, which is straightforward given the panel material and construction. For rack builders and installers who depend on predictable thermal performance in dense AV systems, the MVB Series provides a simple, low-profile solution that does not require permanent modification to the rack.
