Middle Atlantic BGR 276CFM FAN TOP - BGR-276FT

Middle Atlantic BGR-276FT 276 CFM Active Fan Top for BGR-Series Racks

The Middle Atlantic BGR-276FT is an active fan top designed specifically for BGR-series rack enclosures, delivering 276 CFM of airflow to manage heat loads in densely populated AV and security equipment racks. If you're stacking NVRs, PoE switches, and power supplies in a BGR cabinet and running into thermal shutdowns or shortened component lifespans, this is the direct mechanical fix — no controller required, no guesswork about compatibility.

Overview

The BGR-276FT draws on 120V AC input and steps that down internally to 12VDC to drive its 4-inch fan array across a 22.38-inch-wide by 8.72-inch-tall footprint. At just 1.05 inches deep, it occupies minimal vertical space in the rack while moving a meaningful 276 cubic feet per minute out of the enclosure. This is an active, DC-powered cooling unit — passive venting is not a substitute when heat-sensitive equipment like IP cameras, NVRs, or video management servers share a sealed enclosure.

Key Features

• 276 CFM Airflow: Moving 276 cubic feet per minute out of the enclosure is the difference between a rack that stays at ambient and one that climbs 15–20°F above it. For NVRs with spinning HDDs or PoE midspans running near capacity, that temperature delta directly impacts drive longevity and switch reliability — 276 CFM keeps the thermal budget in check for moderately to heavily loaded BGR cabinets.
• 4-Inch Fan Array at 22.38-Inch Width: The fan size and full-width coverage matter here. A 22.38-inch span with 4-inch fans means airflow is distributed across the entire top of the enclosure rather than concentrated at one point — you get more uniform exhaust across all rack units, not just the ones nearest the center.
• 120V AC Input / 12VDC Operation: Standard 120V AC wall input means this plugs into any rack PDU without a separate power brick or voltage conversion. The internal DC conversion to 12V drives the fans efficiently — no separate DC power supply to source or mount, and no additional rack space consumed by a wall wart.
• 1.05-Inch Profile Depth: At just over an inch deep, the BGR-276FT doesn't eat into your rack's vertical real estate the way a full 1U or 2U cooling module would. If your BGR cabinet is already tightly populated, the shallow depth matters.
• 8.72-Inch Height Footprint: This unit is designed to sit on top of the BGR enclosure, not consume internal rack units. The 8.72-inch height accommodates the fan housing above the cabinet without requiring modifications to the enclosure or adjacent wall clearances.
• Active Component Type, No Fan Controller Required: The BGR-276FT runs continuously without a separate fan controller — it's not a variable-speed or thermostatically controlled unit. That's a deliberate tradeoff: simpler wiring, no controller SKU to source, and guaranteed airflow whenever the rack is powered. If you need speed control or temperature-triggered activation, plan for an add-on controller separately.
• BGR Base Series Compatibility: Built for the BGR rack family, so mounting dimensions, footprint, and exhaust geometry align with BGR enclosures without adapters or custom fabrication.

Integration and Compatibility

The BGR-276FT is engineered for Middle Atlantic BGR-series rack enclosures and should be matched to BGR cabinet widths. It is not a universal fan top — verify your BGR cabinet model before ordering to confirm footprint compatibility. This unit is not rated for international use (120V AC only; no 220–240V variant), so deployments outside North America require a verified compatible unit instead.

For integrators building out rack cooling and ventilation solutions, the BGR-276FT pairs naturally with a BGR enclosure and a quality rack PDU. If your thermal load is particularly high — dense NVR arrays, high-wattage PoE switches — consider whether 276 CFM is sufficient or whether a higher-CFM top panel is warranted for the specific enclosure size. Consult Middle Atlantic's thermal guidelines for your BGR cabinet model to confirm. A rack power distribution unit with always-on receptacles ensures the fan top runs continuously as intended.

For full NVR rack deployments, thermal planning should account for the combined wattage of all installed components — NVRs, PoE switches, UPS units, and patch panels — before selecting a fan top CFM rating.

Frequently Asked Questions

Q: What rack series is the BGR-276FT designed for?

A: The BGR-276FT is designed for Middle Atlantic BGR-series rack enclosures. It is not a universal fan top — confirm your BGR cabinet model and dimensions before ordering.

Q: Does the BGR-276FT include a fan speed controller?

A: No. The BGR-276FT is an active, continuously running fan top with no built-in fan controller. It runs at full speed whenever powered. A separate fan controller is required if variable-speed or temperature-triggered operation is needed.

Q: What power input does the BGR-276FT require?

A: It requires 120V AC input, which it converts internally to 12VDC to drive the fans. It is not rated for international (220–240V) use.

Q: How much airflow does the BGR-276FT deliver?

A: The BGR-276FT delivers 276 CFM (cubic feet per minute) of airflow, sufficient for moderately to heavily loaded BGR-series enclosures. Verify against your specific rack's thermal load before specifying.

Q: How deep is the BGR-276FT — will it fit above a wall-mounted BGR cabinet?

A: The BGR-276FT has a depth of 1.05 inches (2.7 cm) and a height of 8.72 inches (22.2 cm). Ensure adequate overhead clearance above the BGR enclosure before installing, particularly in ceiling-constrained or wall-mount environments.

Q: Is the BGR-276FT available for international use?

A: No. The BGR-276FT is rated for 120V AC only and is not available for international deployment. North American installations only.

The BGR-276FT is the fan top I spec when a BGR cabinet is pulling more than a few hundred watts of continuous load — NVRs with four or more drive bays, PoE switches running at 60–70% of their power budget, or any enclosure where the door stays closed in a telecom closet. At 276 CFM through a 22.38-inch-wide top panel, you're exhausting the full rack column, not just skimming the surface near one edge.

Technical Highlights:

• 276 CFM Airflow: For a fully loaded BGR enclosure, 276 CFM provides meaningful thermal headroom — the difference between components operating at manufacturer-rated temps and running 15–20°F hot in a sealed closet install.
• 120V AC → 12VDC Conversion: Plugs directly into any standard rack PDU outlet. No secondary power supply to source, no extra rack space consumed, and no DC power run to worry about during rough-in.
• 1.05-Inch Depth Profile: The shallow footprint means you're not adding significant height above the enclosure in low-clearance installs — relevant in any closet where cable trays or ceiling joists sit close to the top of the rack.

Deployment Considerations:

• The BGR-276FT runs continuously at full speed — there's no thermal trigger or speed control built in. Wire it to an always-on PDU receptacle, not a switched outlet, so cooling doesn't cut out if someone power-cycles the wrong circuit.
• This unit is 120V AC only with no international rating — confirm voltage before specifying for any non-North American site, even if the end client has step-down transformers on site.

This is the right fan top for a BGR-series security rack in a surveillance closet or IT room running 24/7 NVR and switching infrastructure — where passive venting is not enough and a controller adds unnecessary complexity to a rack that just needs to stay cool.
