Middle Atlantic UQFP-4RA-INT Ultra Quiet Rack Intake Fan Panel

Overview

The Middle Atlantic UQFP-4RA-INT is a 2U-equivalent rack-mount intake fan panel engineered for AV, security, and IT enclosures where thermal management can't be an afterthought. Sized at the standard 19-inch rack width and drawing power at a quiet 5 VDC, the UQFP-4RA-INT moves 100 CFM of conditioned intake air without the noise signature that plagues active cooling in client-facing spaces — think control rooms, AV closets, and security head-end racks. If you're stacking NVRs, managed switches, and encoders in a rack that needs sustained airflow without the audible intrusion, this panel is purpose-built for that scenario.

Key Features

• 100 CFM Airflow: Moving 100 cubic feet per minute through a single intake panel provides meaningful positive-pressure ventilation for a densely populated 12U–20U rack. That airflow volume helps push heat away from CPUs, switch ASICs, and recording drives before thermal throttling becomes a factor — a practical spec when you're running 24/7 NVR and switching hardware.
• 5 VDC DC Power Input: Operating on 5 VDC rather than mains voltage keeps the control circuitry isolated from AC line noise. This matters in security racks where sensitive recording and switching equipment shares a common enclosure — DC fan motors are also inherently quieter at low speeds than AC-driven alternatives.
• 120V AC Input Compatibility: The panel accepts standard 120V AC input, which means it integrates directly into North American rack power distribution without special adapters or transformer stages. No rewiring, no additional PDU taps beyond what any standard US installation already has.
• 19-Inch Rack Width: At exactly 19 inches wide, the UQFP-4RA-INT fits any standard EIA-310 rack or enclosure — Middle Atlantic, Legrand, or third-party. No custom brackets, no adapters. Paired with a matching rack enclosure, this is a clean bolt-in install.
• 2.96-Inch Depth: The shallow 2.96 in (7.5 cm) depth means you're not sacrificing cable management space behind the panel. In tight wall-mount or column enclosures where depth is the constraint, this matters more than it sounds.
• 3.5-Inch Panel Height (8.9 cm): The panel height of 3.5 in fits a standard 2U rack opening, keeping the thermal footprint compact relative to the airflow it delivers. You're not giving up four or six rack units just to get intake ventilation.
• Black Brushed and Anodized Finish: The brushed anodized aluminum finish is durable and matches Middle Atlantic's standard rack furniture aesthetics — relevant when the rack is client-visible in a lobby, boardroom, or open security operations center.
• Intake-Only Design: Configured as an intake panel (not exhaust), the UQFP-4RA-INT works best positioned at the bottom of the rack to pull cooler ambient air upward through equipment. Pairing with a corresponding exhaust panel at the top creates a defined airflow path — which is the correct rack cooling strategy for security and AV enclosures.

Integration & Compatibility

The UQFP-4RA-INT is designed for use within Middle Atlantic enclosures and standard 19-inch EIA-310 racks. At 19 inches wide and accepting 120V AC input (converting to 5 VDC for fan operation), it installs without modification into any North American rack power environment. The unit is not available for international distribution — installations outside North America should confirm local voltage and rack-standard compatibility before ordering. Thermal management planning for network video recorders and dense switching gear benefits significantly from this intake panel, particularly when combined with a matched exhaust panel to establish directional airflow. The UQFP 4RA INT (often searched as UQFP 4RA INT) does not include a thermistor, so fan speed is fixed rather than thermally modulated — factor this into your noise and airflow budget if variable-speed operation is a requirement.

Frequently Asked Questions

Q: Does the UQFP-4RA-INT include a thermistor for automatic speed control?

A: No. The UQFP-4RA-INT does not include a thermistor, so fan speed is fixed. It does not automatically ramp up or down based on rack temperature. If variable-speed thermal response is required, evaluate other panels in the Middle Atlantic thermal management line that include thermistor control.

Q: What rack width does the UQFP-4RA-INT fit?

A: The panel is 19 inches wide, fitting any standard EIA-310 19-inch rack or enclosure. No adapters or modifications are needed for a standard North American rack installation.

Q: Is the UQFP-4RA-INT available for international use?

A: No. Per manufacturer data, this unit is not available internationally. It is rated for 120V AC input, which limits use to North American electrical environments.

Q: What is the airflow rating of the UQFP-4RA-INT?

A: The UQFP-4RA-INT is rated at 100 CFM (cubic feet per minute) of intake airflow, sufficient to provide positive-pressure ventilation for a densely populated security or AV rack when positioned as a bottom intake panel.

Q: How deep is the UQFP-4RA-INT — will it interfere with rear cable management?

A: The panel is 2.96 inches (7.5 cm) deep, which is shallow enough to preserve rear cable management clearance in most standard rack enclosures.

Q: What powers the UQFP-4RA-INT fans?

A: The fans operate on 5 VDC. The panel accepts 120V AC input and converts internally to 5 VDC for fan operation — no separate low-voltage power supply is required.

Ted Perry

The UQFP-4RA-INT is the panel I reach for when a client needs real intake airflow — 100 CFM — without the acoustic footprint of a traditional rack fan tray. The 5 VDC DC motor design keeps both the noise floor and the electrical interference low, which is exactly what you want in a security head-end rack running continuous NVR and switching loads.

Technical Highlights:

• 100 CFM Intake: At 100 CFM, this panel moves enough air to establish positive pressure in a populated rack — critical for preventing recirculation of hot exhaust air back through sensitive recording hardware.
• 5 VDC DC Fan Operation: DC motors at 5 V run quieter and with less electromagnetic interference than AC fan motors, making this the right choice for racks in noise-sensitive environments like operations centers or client-facing AV closets.
• 2.96-Inch Depth: The shallow depth of under 3 inches preserves rear cable management clearance — a real constraint in column enclosures and wall-mount racks where depth is already at a premium.

Deployment Considerations:

• Position the UQFP-4RA-INT at the bottom of the rack as a low intake, and pair it with a dedicated exhaust panel at the top — this establishes the bottom-to-top airflow path that maximizes thermal efficiency across all installed gear.
• No thermistor means fixed fan speed — there is no automatic ramp-up under thermal load. In environments with highly variable rack density or seasonal ambient temperature swings, account for worst-case airflow needs at spec time rather than relying on speed adjustment.

This panel is a natural fit for security integrators deploying dense NVR and PoE switching stacks in Middle Atlantic enclosures where a quiet, predictable 100 CFM intake is the thermal baseline requirement — particularly in commercial control rooms or client-visible head-end closets where fan noise is a deliverable, not an afterthought.
