Middle Atlantic SNE 30W FAN Fd/rd 42U - SNE30-CFD-42

Middle Atlantic SNE30-CFD-42 42U Split Fan Door for 30-Inch SNE Racks

Overview

The Middle Atlantic SNE30-CFD-42 is a split fan door purpose-built for 42U, 30-inch-wide SNE series racks that need active thermal management without sacrificing front or rear access. If you're running dense video or security equipment — NVRs, encoders, PoE switches, network gear — passive ventilation often isn't enough. This door integrates active cooling fans directly into both the front and rear door panels, which means airflow is driven through the rack rather than left to convection. At 38.50 lbs, it's a substantial assembly built for permanent installation in equipment rooms, IDF closets, and command center enclosures.

The SNE30-CFD-42 (often searched as SNE30 CFD 42) is part of Middle Atlantic's SNE 30 Wide series — a family of racks and rack accessories designed around the 30-inch depth/width form factor that's become a standard in professional AV and physical security installations. The active fan door drops directly into the SNE rack framework without aftermarket brackets or custom fabrication.

Key Features

• Integrated Active Cooling — Front and Rear: Fans are built into both door panels, not retrofit-mounted. This gives you positive airflow across the full 42U column — critical when you're stacking high-wattage PoE switches, recorders, and servers in the same enclosure. Convection alone won't move enough air in a sealed, dense rack.
• 42U Height — Full Rack Column: At 76.076 inches tall, this door covers the entire 42U enclosure height with no gaps. A split design means you can open the top or bottom half independently for cable access or equipment swaps without disturbing active airflow on the other half.
• 30-Inch SNE Series Compatibility: Designed specifically for 30-inch wide SNE racks. If you're running a 24-inch or non-SNE enclosure, this door is not the right fit — verify your rack series and width before ordering. Mismatched door widths are the most common install error on rack accessory orders.
• 29.809-Inch Width — Near Flush Fit: At just under 30 inches wide, the door fits flush with the SNE rack frame without overhang. The 2.3509-inch depth adds minimal footprint to the front or rear of the enclosure — relevant in tight IDF rooms where door swing clearance is constrained.
• 38.50 lb Assembly Weight: This is a heavy component. Plan for two-person installation. The weight reflects the robust fan and door frame construction — not a lightweight louvered panel — which matters when you're relying on it to handle continuous thermal load in a production environment.
• Black Texture Powder Coat Finish: The powder coat surface resists scratching during installation and looks consistent with standard Middle Atlantic rack aesthetics. Not a cosmetic-only detail — powder coat holds up better than painted finishes in environments where doors are opened frequently for maintenance access.
• Rack Mount Configuration: Mounts directly to the SNE rack frame via the standard Middle Atlantic mounting interface. No wall anchoring or floor-standing support required — the rack itself carries the door weight.

Integration and Compatibility

The SNE30-CFD-42 is engineered for the SNE 30 Wide rack enclosure series. Before ordering, confirm your rack is a 30-inch-wide SNE model — Middle Atlantic produces multiple rack lines (WR, WMRK, BGR, SNE) with different widths and mounting interfaces that are not cross-compatible with this door assembly.

For installations pairing this rack with active surveillance and network gear, pair it with a rack-mount PDU rated for your total equipment wattage so the fan load doesn't push you over the circuit budget. Also consider cable management panels from the SNE accessory line to keep airflow paths clear — balled-up cable runs inside the rack defeat the purpose of active fan cooling.

If your deployment includes NVRs or edge servers running 24/7, a fan door like this is often the difference between stable thermal operation and thermal throttling during peak summer ambient temperatures in a non-HVAC equipment room.

Frequently Asked Questions

Q: What rack series is the SNE30-CFD-42 compatible with?

A: The SNE30-CFD-42 is designed specifically for Middle Atlantic's SNE 30 Wide series racks — 42U, 30-inch-wide enclosures. It is not cross-compatible with other Middle Atlantic rack lines or third-party enclosures. Verify your rack model before ordering.

Q: Does the SNE30-CFD-42 include fans on both the front and rear doors?

A: Yes. The split fan door integrates active cooling fans into both the front and rear door panels, driving airflow through the full rack column rather than relying on passive convection.

Q: What are the dimensions of the SNE30-CFD-42?

A: The door assembly measures 29.809 inches wide, 2.3509 inches deep, and 76.076 inches tall, with a shipping weight of 38.50 lbs.

Q: Can I open the top and bottom independently?

A: Yes. The split design allows the top and bottom halves to open independently, so you can access cables or swap equipment in one zone without disrupting the door configuration on the other half.

Q: How many people does it take to install the SNE30-CFD-42?

A: At 38.50 lbs, this is a two-person installation. Attempting to mount it solo risks misalignment and physical injury.

Q: What finish does the SNE30-CFD-42 come in?

A: Black texture powder coat — consistent with standard Middle Atlantic rack aesthetics and more durable than painted finishes under repeated maintenance access.

The SNE30-CFD-42 is one of those components that looks simple on the spec sheet but makes a real operational difference once you've lived through a thermal incident in a dense security rack. At 38.50 lbs with fans integrated into both door panels, this isn't a decorative louvered cover — it's active thermal infrastructure for your SNE 30-inch enclosure. I specify this door on projects where the rack is running NVRs plus PoE switching plus edge compute in a space without dedicated HVAC, because passive airflow in that scenario isn't a strategy, it's a hope.

Technical Highlights:

• Dual Active Fan Panels: Fans built into both front and rear doors drive forced airflow across the full 42U column — not just exhausting heat, but pulling fresh air through. That front-to-rear airflow path is what actually moves heat away from hot components rather than recirculating it inside the enclosure.
• 76.076-Inch Full-Height Coverage: The door covers the entire 42U column with no thermal bypass gaps at top or bottom. Partial-height fan panels leave dead zones where heat stratifies — this design eliminates that.
• Split Door Mechanism: The top and bottom halves open independently. In a live production rack, that means you can pull cables or swap a drive tray in the bottom half without opening the full 76-inch assembly and disrupting airflow management on running equipment above.

Deployment Considerations:

• Confirm your rack is an SNE 30 Wide model before ordering — the mounting interface and width (29.809 inches) are specific to that series. Ordering for a WR or BGR rack results in a return, not a workaround.
• At 38.50 lbs, this is a mandatory two-person lift. Budget the labor accordingly during rack commissioning — trying to hang this solo while aligning the hinge points is how you get a misaligned door that binds on the frame.

This door is the right call for command center and IDF buildouts where SNE 30-inch racks are running 24/7 security workloads in rooms without precision cooling — it keeps thermals stable without requiring a full CRAC unit just to protect one rack column.
