Lowell MVB Series Magnetic Vent Blockers For LGR Rack | MVBLGR

The Lowell MVB Series magnetic vent blockers are designed for AV integrators and systems installers who need reliable thermal control inside rack enclosures. Effective airflow management is critical in installed rack systems housing amplifiers, DSPs, and network equipment that generate sustained heat loads. These panels work alongside fan panels to direct airflow by blocking unintended vent paths at the top front, sides, and top of the rear door interior.

Panels in the MVB Series are sized to match Lowell LGR, LER, LWBR, and LWR series rack enclosures, reducing the guesswork in fitting. The magnetic mounting surface allows repositioning without fasteners, making adjustments straightforward during commissioning or when rack contents change. Some field trimming may be required to achieve a precise fit for specific vent locations. This series is a practical, low-cost addition to any installation where active thermal management is part of the rack design.
