Catalog / Airflow & Containment
Airflow & Containment
Open rack units let hot exhaust air recirculate back into equipment intakes. Blanking panels, brush grommets, and air dams close those paths so cold air reaches the equipment that needs it and hot air leaves the row.
What we supply
Blanking panels
Snap-in and screw-mount panels for 19 in EIA racks, 1U through 8U. Polymer and steel. Tool-less designs install without cage nuts and remove without hardware, which matters in cabinets that get reconfigured.
Specify by: rack units, mounting method, material, color.
Brush grommets and cable entry
Sealed pass-throughs for cable entry at the rack floor, roof, or rear panel. Bristle density determines how much air the opening leaks once cable is run through it.
Specify by: cutout dimension, bristle type, frame material, mounting orientation.
Air dams and side baffles
Foam and polymer barriers that close the gap between mounting rails and cabinet side panels, the second largest recirculation path after open rack units.
Specify by: rail depth, cabinet width, material.
Containment accessories
Aisle end panels, roof panels, and gap filler for hot aisle and cold aisle containment.
Specify by: aisle width, cabinet height, panel material.
Specifying airflow management
Every unused rack unit is closed. A partially blanked rack recirculates in proportion to what remains open.
Cable openings are sealed, not just routed through. An unsealed 4 in by 12 in floor cutout leaks more air than four open rack units.
Side gaps are closed at the rail. Blanking the front without closing the rail-to-sidewall gap moves the recirculation path rather than eliminating it.
