Vertiv VC-AC-0004 Aisle Containment Blanking Panel
Overview
The Vertiv VC-AC-0004 is a 31.5-inch (800mm) blanking panel designed for use with Vertiv aisle containment systems. Blanking panels serve a specific and often underestimated role in data center cooling infrastructure: they seal open horizontal gaps in aisle containment assemblies, preventing conditioned cold air from bypassing equipment and mixing prematurely with hot exhaust air. Every unsealed gap forces your CRAC or CRAH units to work harder and reduces the effective cooling capacity available at the rack inlet — the VC-AC-0004 eliminates that waste at the containment level rather than at the rack level.
Key Features
- 31.5-inch (800mm) panel width: Sized to span standard 800mm-wide aisle containment bays — matches Vertiv's containment column and overhead structure spacing so you get a flush, gap-free fit without field modification.
- Steel or aluminum construction: Metal construction holds its geometry under the thermal cycling and airflow pressure differentials common in active containment environments, unlike plastic panels that can bow over time and reopen gaps.
- Black finish: Matches standard Vertiv aisle containment accessories for a consistent appearance in cold aisle or hot aisle enclosures.
- Drop-in containment integration: Designed specifically for Vertiv containment system geometry — eliminates the guesswork of sourcing generic filler panels that require shimming or custom cuts to seal correctly.
Integration & Compatibility
The VC-AC-0004 (often searched as VC AC 0004) is designed for Vertiv aisle containment systems. Confirm your containment bay width is 800mm before ordering — Vertiv offers alternate-width blanking panels for other bay dimensions. If you are planning a data center infrastructure build-out or retrofit, pair these blanking panels with Vertiv's containment doors, ceiling tiles, and cable pass-through grommets to achieve the full containment effect. Partial sealing produces proportionally reduced cooling gains.
Frequently Asked Questions
Q: What width aisle containment bays does the VC-AC-0004 fit?
A: The VC-AC-0004 is sized for 800mm (31.5-inch) wide aisle containment bays in Vertiv containment systems.
Q: What material is the VC-AC-0004 made from?
A: The panel is constructed from steel or aluminum with a black finish, providing durability under data center thermal cycling conditions.
Q: Can the VC-AC-0004 be used with non-Vertiv aisle containment systems?
A: The VC-AC-0004 is designed specifically for Vertiv aisle containment systems. Compatibility with third-party containment structures is not confirmed by available evidence — verify bay dimensions and mounting interface before ordering for non-Vertiv applications.
Q: Why use a blanking panel at the aisle containment level rather than blanking rack units?
A: Rack-level blanking panels seal gaps within individual cabinets. Aisle containment blanking panels like the VC-AC-0004 seal the overhead or end-of-row structure of the containment enclosure itself — both are needed for a fully sealed containment environment.
The VC-AC-0004 is the kind of component that gets overlooked in containment build plans and then causes real cooling headaches post-commissioning. A single unsealed 800mm bay gap in an otherwise complete hot aisle containment setup can allow enough bypass air to skew inlet temperature readings by several degrees — enough to trigger premature CRAC cycling or push rack inlet temps above ASHRAE A2 limits under peak load. This panel exists to prevent that.
Technical Highlights:
- 800mm panel width: Matches Vertiv containment bay spacing exactly — no field cutting, no shimming, no residual gap at the panel edge that defeats the containment seal.
- Metal construction: Steel or aluminum holds dimensional stability under the positive/negative pressure differentials that active containment systems generate; plastic alternatives can flex and gap over time under sustained airflow pressure.
- Black finish: Aligns with standard Vertiv containment hardware aesthetics — relevant for customer-facing data centers or colocation environments where visual consistency matters during site tours or audits.
Deployment Considerations:
- Order the VC-AC-0004 at the same time as your containment structure — retrofitting blanking panels after initial commissioning often requires partial disassembly of the overhead containment frame to insert panels correctly.
- Verify your bay count precisely before ordering; a single missing panel in a completed containment row can undermine the PUE gains you calculated for the project.
The VC-AC-0004 is the right specification for facilities teams completing or retrofitting 800mm Vertiv aisle containment rows in high-density compute environments where measurable PUE improvement is a project deliverable — not a nice-to-have.
