Vertiv VC-AC-0008 Aisle Containment Height Adapter
Overview
The Vertiv VC-AC-0008 is a 2U x 600mm height adapter designed to close dimensional gaps in aisle containment systems. In hot-aisle and cold-aisle containment deployments, even a small unmated gap between containment panels and adjacent rack infrastructure bleeds conditioned air directly into the return path — undermining the entire thermal separation the enclosure was installed to achieve. The VC-AC-0008 (often searched as VC AC 0008) addresses that problem as a purpose-built accessory, letting you adapt containment height to match the actual rack elevation without resorting to improvised blocking materials that degrade over time.
This is a single-unit accessory. Each package contains one adapter sized at 2U in height and 600mm in width — matching the standard 600mm rack column footprint common in two-post and four-post open-frame and enclosed rack systems. If you are specifying a containment row with mixed-height racks or transitioning between standard 42U and taller 48U or 52U cabinets, the VC-AC-0008 fills the height delta in 2U increments, keeping the containment plane continuous from floor to ceiling or from canopy to rack top rail.
Key Features
- 2U Height Increment, 600mm Width: Fills the most common gap size encountered when mixing standard-height and extended-height racks in the same Vertiv aisle containment row. Stacking multiple VC-AC-0008 units lets you address larger deltas without custom fabrication — no lead time, no special order.
- Purpose-Built Fit: Designed to integrate directly with Vertiv's aisle containment system geometry. Using manufacturer-matched components eliminates the fitment guesswork that comes with generic blanking panels repurposed as height fillers — the profiles align, the edges seal, and the thermal boundary stays intact.
- Maintains Thermal Separation: Every unsealed opening in a containment enclosure is a bypass path for hot return air. A 2U gap at 600mm wide represents enough open area to measurably reduce the supply/return air temperature differential — which translates directly to compressor load on the CRAC/CRAH units serving the row. Closing that gap with the VC-AC-0008 keeps the thermal efficiency numbers the containment system was specified to deliver.
- Single-Unit Package: Shipped as one adapter per package, so you can order exactly the quantity your row layout requires rather than buying a multi-pack with leftover units.
- Scalable Gap Correction: Because the adapter increments in 2U steps, multi-unit installations can address 4U, 6U, or larger gaps in a predictable, ordered way. This also means future rack additions that shift height alignment can be corrected by adding or removing individual adapters rather than replacing a large panel.
- Vertiv Ecosystem Compatibility: Sourced as a Vertiv accessory, the VC-AC-0008 is designed to work within Vertiv's broader aisle containment accessory portfolio — including end-of-row doors, canopy systems, and blanking panels. Specifying within a single ecosystem reduces the risk of profile mismatches at the joints.
Integration and Compatibility
The VC-AC-0008 is specified for use with Vertiv aisle containment systems where 600mm-wide rack columns are deployed. Confirm your rack column width before ordering — 800mm rack environments require a different adapter width. The 2U height dimension is standardized (1U = 1.75 inches / 44.45mm), so a single VC-AC-0008 fills 88.9mm (approximately 3.5 inches) of vertical gap. For deployments using Vertiv's SmartRow or VR-series rack lines, verify the containment canopy attachment points are compatible with the height adapter profile. When planning a data center power and cooling refresh that includes new containment infrastructure, account for the height adapter quantity in your BOM at the cabinet-layout stage — it is easier to order with the primary containment components than to source them separately after installation.
Frequently Asked Questions
Q: What rack width is the VC-AC-0008 designed for?
A: The VC-AC-0008 is sized for 600mm-wide rack columns. If your deployment uses 800mm racks, you will need a different adapter width — verify your rack column dimension before ordering.
Q: How much vertical height does one VC-AC-0008 unit cover?
A: One unit covers 2U of vertical height. At the standard 1U = 44.45mm, that equals approximately 88.9mm (3.5 inches) of gap fill per adapter. Multiple units can be stacked to address larger gaps.
Q: How many adapters come in one package?
A: One adapter per package. Order the exact quantity your row layout requires.
Q: Can the VC-AC-0008 be used with non-Vertiv aisle containment systems?
A: The VC-AC-0008 is a Vertiv-branded accessory engineered to fit Vertiv aisle containment geometry. Compatibility with third-party containment systems is not confirmed by the manufacturer — measure attachment profiles carefully before specifying outside a Vertiv ecosystem.
Q: Why does closing a 2U gap matter for thermal efficiency?
A: An unsealed 2U x 600mm gap in a containment enclosure creates an open bypass path where hot return air mixes with cold supply air. This reduces the temperature differential available to your CRAC/CRAH units, increasing compressor load and reducing the effective cooling capacity of the row. Sealing that gap restores the containment system's designed thermal separation.
The VC-AC-0008 is a straightforward but operationally important accessory — it fills a 2U x 600mm vertical gap in a Vertiv aisle containment deployment, and that specific dimension matters more than it looks on a BOM. A single unsealed 2U gap at 600mm width is enough open area to measurably reduce the hot/cold air temperature differential in a contained row, which means your cooling infrastructure is working harder than the containment spec said it would.
Technical Highlights:
- 2U Height Coverage: At 44.45mm per U, one adapter closes 88.9mm of vertical gap — enough to bridge the most common cabinet-height mismatch without stacking an awkward number of units.
- 600mm Width Match: Aligns directly with the standard 600mm rack column footprint, so it seats flush against the containment panel without shimming or trimming.
- Single-Unit Packaging: Order precisely what the row layout requires — no surplus, no minimum multi-pack. This matters on phased deployments where rack height alignment changes as you add cabinets.
Deployment Considerations:
- Confirm rack column width is exactly 600mm before ordering — the VC-AC-0008 will not fit cleanly in an 800mm-column environment, and the mismatch creates the gap you were trying to close.
- For gaps larger than 2U, you will need to stack multiple units. Plan adapter quantities at the BOM stage alongside the primary containment components — sourcing them after initial installation adds a delay to your thermal commissioning sign-off.
This adapter is the right call for data center rows where mixed-height racks create incremental height mismatches at the containment canopy line — specifically in 600mm-column environments where you need a manufacturer-matched solution rather than improvised blocking that degrades the containment seal over time.
