Lowell MVB32 Magnetic Vent Blocker Kit For LER 32" Depth Racks

The Lowell MVB32 is a magnetic vent blocker kit designed for use with Lowell LGR, LER, LWBR, and LWR series racks, sized specifically for racks with 32 in. depth. These panels are intended to cover vents located at the top front, sides, and top of the rear door in the rack interior, allowing installers to direct airflow precisely when active thermal management is a priority.

Rack integrators and AV system installers who deploy fan panels in enclosed equipment racks will find these blockers essential for channeling conditioned airflow rather than allowing passive bypass. Without proper vent coverage, fan panels lose efficiency as air recirculates through uncovered openings. The MVB32 addresses this directly with a magnetic attachment system that mounts cleanly to the rack interior without fasteners, simplifying field installation. Some field trimming may be required to achieve a precise fit depending on rack configuration.

The panels are finished in black to match standard rack interiors and constructed from rigid blocking material. For AV system integrators managing heat-sensitive equipment in permanent installations, the MVB32 provides a reliable, low-profile solution for closing thermal bypass paths without permanent modification to the rack enclosure.
