Middle Atlantic ERK-4QFT-FC Quiet Fan Top with Active Fan Control
Overview
The ERK-4QFT-FC is a rack-mount fan top unit designed to force 165 CFM of active airflow through Middle Atlantic ERK series enclosures. Three 4-inch quiet fans run at variable speed via an integrated fan controller — meaning you get the airflow you need without the constant full-speed noise that comes with passive or uncontrolled fan tops. The ERK-4QFT-FC runs on 120V AC and steps down to 12V DC to drive the fan array, so no separate DC supply is required. At 1.83 inches deep and 19.75 inches wide, it occupies a standard 1U footprint at the top of the rack. If your AV or security equipment rack runs warm under load — NVRs, managed switches, encoder appliances — this unit gives you a controlled, low-noise solution rather than relying on passive convection or a loud always-on fan panel.
Compatibility
Designed specifically for the Middle Atlantic ERK (Elite Rack) series enclosures. The 19.75-inch width and 1.83-inch depth conform to ERK series top-panel dimensions. Verify your specific ERK rack model accepts a fan top accessory at the top bay — the ERK-4QFT-FC is engineered to drop into that position with no modification. This unit is not rated for international voltage and requires a 120V AC supply; installations outside North America will need a step-down transformer or a different model. For integrators specifying rack cooling accessories across mixed AV and network video recorder deployments, confirm the ERK enclosure depth matches your cable management and equipment layout before ordering — the fan top occupies the full top aperture.
Installation Notes
Mounts at the top of the ERK rack enclosure. Input is 120V AC; output to the fan array is 12V DC — both are handled internally. The active fan controller adjusts fan speed in response to temperature, which keeps acoustic output low during idle periods and ramps airflow when the rack heats under load. Shipping weight is 13 lbs; account for that when planning rack weight budgets. This product is not available for international shipment.
