The Vertiv VC-AC-0003 is a 600 mm (23.62 in.) wide blanking panel designed for hot-aisle/cold-aisle containment systems in data centers and network equipment rooms. Blanking panels serve a straightforward but load-bearing purpose in any well-managed server environment: they close open rack units and containment gaps that would otherwise allow hot exhaust air to recirculate back into equipment intakes — a cycle that forces cooling systems to work harder and raises operating temperatures across the row. If your containment system has unsealed gaps, you are paying for cooling capacity you are not actually getting. The VC-AC-0003 addresses that problem at the aisle level, not just at the individual rack.
At 600 mm wide, the VC-AC-0003 is sized for standard aisle containment frame widths common in Vertiv aisle containment configurations. This is a sold-as-single-unit (1-pack) panel, so you can order exactly the quantity your floor plan requires without committing to bulk packs that leave excess inventory on the shelf. Explore the full Vertiv catalog for compatible containment frames, roof panels, and end-of-row doors that pair with this blanking panel.
The VC-AC-0003 is intended for use within Vertiv aisle containment systems. Compatibility depends on the specific containment frame model installed in your facility — confirm the frame accepts 600 mm wide blanking panels before ordering. If you are planning a new containment deployment, cross-reference the VC-AC-0003 against your rack and containment accessories bill of materials. This panel does not include mounting hardware beyond what Vertiv's containment frame system provides; installation follows the containment frame's tool-free or fastener-based panel retention method, depending on the frame generation.
For facilities managers specifying a complete containment retrofit, the VC-AC-0003 works alongside Vertiv end-of-row doors, roof panels, and side seals to achieve a fully closed containment environment. Pair with a data center cooling assessment if you are sealing a previously open-aisle environment — closing containment gaps changes airflow patterns and may require CRAC setpoint adjustment.
Q: What width is the VC-AC-0003 blanking panel?
A: The VC-AC-0003 blanking panel is 600 mm (23.62 in.) wide, sized for standard Vertiv aisle containment frame bays.
Q: How many panels come in one order of VC-AC-0003?
A: The VC-AC-0003 is sold as a 1-pack — one blanking panel per unit ordered. This allows you to purchase the exact number of panels needed to fill open bays in your containment system.
Q: Is the VC-AC-0003 compatible with all Vertiv aisle containment frames?
A: The VC-AC-0003 is designed for Vertiv aisle containment systems, but compatibility depends on your specific frame model. Confirm that your installed containment frame accepts 600 mm wide blanking panels before ordering.
Q: What is the shipping weight of the VC-AC-0003?
A: The VC-AC-0003 has a listed weight of 21 lbs.
Q: Does the VC-AC-0003 include mounting hardware?
A: Mounting method depends on the Vertiv containment frame installed in your facility. The panel is designed to integrate with Vertiv's containment frame system; consult your containment frame documentation for panel retention details.
Q: Can the VC-AC-0003 be used in both hot-aisle and cold-aisle containment configurations?
A: The VC-AC-0003 is an aisle containment blanking panel suitable for sealing gaps in containment structures. Whether it is deployed in a hot-aisle or cold-aisle configuration depends on your facility layout and the containment frame it is installed in — the panel itself seals the physical gap regardless of which aisle is being contained.

The VC-AC-0003 comes up in projects where a containment buildout has open gaps that are quietly wrecking cooling efficiency — the 600 mm panel width tells you immediately whether it fits your frame bay, and the 1-pack purchasing model means you can close out a punch-list of remaining open bays without ordering surplus stock.
Technical Highlights:
Deployment Considerations:
The VC-AC-0003 is the right call for a data center facilities team closing out a Vertiv aisle containment installation where specific frame bays remain unsealed — particularly in a colocation environment where per-cage PUE accountability makes every unsealed gap a billable inefficiency.
