Passive Air Sealing & Containment

Blanking panels, brush panels, split floor grommets, gap seals and aisle containment — the passive parts that keep cold and hot air where the cooling design expects it.

Tool-less Blanking Panels (1U / 2U)Snap-in 19-inch blanking panels for EIA-310 square-hole racks. Flame-retardant ABS (UL94 V-0 grades), 1U and 2U heights, installed without screws or cage nuts.View product

Rack Cable Pass-Through Brush Panels (1U / 2U)19-inch brush strip panels that let patch and power cables pass front-to-back through the rack while limiting bypass airflow. 1U and 2U, solid or split for retrofit.View product

Split Raised-Floor Brush GrommetsBrush-sealed cable grommets for raised-floor tile cut-outs. Split frames fit around cables that are already installed, so openings can be sealed during live retrofits. Rectangular and round formats, sized to the cut-out.View product

Rack Gap Seals: Brush, Magnetic & Foam StripsSeals for the gaps between cabinets, under cabinets and around containment: brush strips, thin magnetic strip rolls, expanding foam tape and under-rack skirts — cut to length for mixed-brand rows.View product

What “passive air sealing” covers

Cooling air takes the easiest path. Every empty rack unit, cable opening, gap between cabinets and hole in a raised-floor tile is a path that bypasses IT equipment. Passive sealing closes those paths without moving parts or power — which is why operators and integrators buy it as one package per rack row.

How to specify a sealing package

  1. Audit empty U per rack, floor cut-outs (size and cable fill) and gap widths along each row.
  2. Match fit: rail type for panels, cut-out size and usable opening for grommets, surface (steel or not) for magnetic seals.
  3. Check materials: flame ratings of plastics are material data (e.g. UL94 V-0 resin), not listings of the finished part.
  4. Order per row: panels, grommets and seals packed by rack row simplify installation.

We do not publish energy-saving percentages for individual products; the US DOE/LBNL guidance treats air management as a combination of measures. See also our measuring guide for floor cut-outs.
