Middle Atlantic 35SP Large Perf FR Door - LVFD-35

Middle Atlantic LVFD-35 35U Large Vented Front Rack Door

Overview

The Middle Atlantic LVFD-35 is a 35U large perforated front door engineered for DWR and EWR series rack enclosures where thermal management is a primary concern. At 62.12 inches tall and 20.04 inches wide, this door covers a full 35-rack-unit bay while delivering 64% vent open area — meaning nearly two-thirds of the door face is open to airflow. For integrators deploying dense NVRs, PoE switches, and video servers in security operations centers or IT closets, that ventilation figure directly reduces the risk of thermal throttling and premature hardware failure.

Finished in a textured black powder coat, the LVFD-35 (often searched as LVFD 35) fits cleanly into professional rack installations where appearance and durability both matter. The perforated steel construction handles the mechanical demands of a working rack environment while keeping the airflow path unobstructed.

Key Features

• 64% Vent Open Area: With nearly two-thirds of the door face open, natural convection and active cooling systems can both operate efficiently — critical in rack bays running 24/7 security recording servers where heat accumulates fast. A solid door on the same enclosure would force you to rely entirely on top-exhaust fans; this door gives passive airflow a real path.
• 35 Rack Units (62.12 in tall): Sized for full-height rack enclosures in the DWR and EWR series. A 35U bay comfortably accommodates an NVR, PoE switch stack, patch panel, UPS, and cable management — the LVFD-35 covers the entire front face as a single panel rather than requiring multiple partial doors.
• 20.04-Inch Width: Matches the standard width profile of Middle Atlantic DWR and EWR enclosures. Verify your base enclosure width before ordering — this door is dimensioned specifically for this series and will not fit narrower or non-compatible enclosure families.
• 1.39-Inch Depth Profile: The door adds less than 1.4 inches of depth to the enclosure footprint. In tight IDF closets or wall-mount alcoves where clearance is measured carefully, that shallow swing profile matters for both door operation and front-access compliance.
• Textured Black Powder Coat Finish: The textured surface resists fingerprints and minor abrasion better than smooth powder coat — a practical consideration in operational environments where technicians are opening the door repeatedly under less-than-ideal lighting conditions. The finish also matches the standard Middle Atlantic enclosure palette for a consistent rack aesthetic.
• DWR and EWR Series Compatibility: Designed as a direct-fit replacement or upgrade door for Middle Atlantic DWR (Data/Wall Rack) and EWR enclosures. If you're retrofitting an existing enclosure that shipped with a solid door, the LVFD-35 is a drop-in upgrade to improve airflow without replacing the full rack. Review rack door and accessory options to confirm the correct series match for your enclosure model.
• 34 lb Shipping Weight: Heavier than it might appear — plan for two-person installation when mounting or swapping this door on an already-populated rack. The steel construction accounts for the weight; this is not a lightweight consumer-grade panel.

Integration and Compatibility

The LVFD-35 is engineered specifically for Middle Atlantic DWR and EWR series enclosures. Before ordering, confirm your base enclosure model falls within one of these series — the door hinges, latch hardware, and frame geometry are matched to these enclosure families. It is not a universal-fit door and should not be assumed compatible with other Middle Atlantic enclosure lines or third-party racks.

For integrators building out surveillance infrastructure, pairing a vented front door with proper rear exhaust and structured rack cooling and airflow planning is standard practice. The 64% open area on the LVFD-35 supports both passive stack cooling and active fan-tray configurations mounted inside the enclosure. If your rack also requires rear ventilation, Middle Atlantic offers matching vented rear door options within the same enclosure series.

This door is also a practical upgrade path for existing DWR or EWR racks that were originally deployed with solid front doors — a common scenario when security system loads grow and thermal issues emerge post-installation.

Frequently Asked Questions

Q: What rack enclosure series is the LVFD-35 compatible with?

A: The LVFD-35 is designed specifically for Middle Atlantic DWR (Data/Wall Rack) and EWR series enclosures. Confirm your base enclosure falls within one of these series before ordering — it is not a universal-fit door.

Q: What is the vent open area percentage on the LVFD-35?

A: The LVFD-35 has a 64% vent open area, meaning nearly two-thirds of the door face is perforated for airflow. This supports both passive convection and active cooling configurations inside the rack.

Q: What are the exact dimensions of the LVFD-35?

A: The LVFD-35 measures 62.12 inches (157.8 cm) tall, 20.04 inches (50.9 cm) wide, and 1.39 inches (3.5 cm) deep. It covers a 35U rack bay.

Q: What finish does the LVFD-35 have?

A: The LVFD-35 is finished in a textured black powder coat, which matches the standard Middle Atlantic enclosure palette and resists fingerprints and minor surface abrasion.

Q: Can the LVFD-35 be used as a replacement door on an existing rack?

A: Yes — the LVFD-35 is a direct-fit door for DWR and EWR series enclosures and can replace a solid front door on an existing rack to improve ventilation without requiring a full enclosure swap.

Q: How much does the LVFD-35 weigh?

A: The shipping weight is 34 lbs (15.4 kg). Plan for two-person handling during installation, particularly when working on an already-populated rack.

The spec that drives the purchasing decision on the LVFD-35 is the 64% vent open area — not the finish, not the rack unit count. When you're running a 35U bay packed with NVRs and PoE switches in a security ops room, a solid front door is a thermal liability. The LVFD-35 gives you nearly two-thirds of that front face open, which is enough to meaningfully support passive stack cooling and lets active fan trays operate without fighting a restricted intake.

Technical Highlights:

• 64% Vent Open Area: At 64% perforation, this door creates a low-restriction intake path. Paired with rear exhaust, you get a defined front-to-back airflow lane rather than heat recirculating inside a sealed enclosure.
• 35U / 62.12-Inch Height: Full-height coverage at 35 rack units means a single door for a full bay — no stacked partial panels, no gap at the top where heat escapes forward instead of out the rear exhaust path.
• 1.39-Inch Depth Addition: Less than 1.4 inches added to the enclosure footprint. In constrained IDF closets where front clearance is measured against fire egress or adjacent equipment, this shallow profile keeps you compliant with most installation clearance standards.

Deployment Considerations:

• Verify your base enclosure is confirmed DWR or EWR series before ordering — the LVFD-35 hinge and latch geometry is series-specific. Middle Atlantic enclosure model numbers are usually stamped on the inside of the enclosure rail; cross-reference before procurement to avoid a return.
• At 34 lbs shipping weight, the door itself is heavy enough to warrant two-person handling, particularly on a populated rack where you cannot easily stabilize the enclosure. Budget the install time accordingly.

The LVFD-35 is the right specification for a 35U security infrastructure rack in a climate-controlled equipment room where passive ventilation is part of the thermal strategy — specifically, any DWR or EWR build running continuous-duty recording loads where a solid door would otherwise require oversized active cooling to compensate.
