Vent Blockers
VBK Series Vent Blockers are used to promote active thermal management.
Designed to prevent the re-circulation of hot air between top-mount fans and nearby
vent openings, Vent Blockers should be placed over the enclosure’s vents located on
the upper front of the enclosure, upper sides, and upper rear door (depending on
enclosure). This will ensure that heated enclosure air will be forced out through the
top-mounted exhaust fans instead of re-circulating, keeping equipment cool.

stray magnetic fields
