Middle Atlantic Quiet 2 Blower Panel with Proportional Speed Fan Control 1 Space Black - QBP-2A

Middle Atlantic QBP-2A 1U Quiet Rack Blower Panel

Overview

The Middle Atlantic QBP-2A is a 1U rack-mount blower panel engineered for rack thermal management in AV, security, and network enclosures where heat buildup is a risk but noise is a constraint — server rooms, control rooms, and equipment closets where fans running at full speed are not acceptable. The QBP-2A moves 100 CFM of airflow through a single rack unit and holds noise output to 32 dB, which is quiet enough for occupied spaces. Thermostatic (proportional speed) control means the fan ramps up only as internal temperatures rise, so it runs quietly at low loads and accelerates automatically under thermal stress — no manual adjustment, no constant full-speed noise. Power input is 12V DC, compatible with standard rack power distribution. The black brushed anodized finish integrates cleanly into Middle Atlantic rack systems and most third-party 19-inch enclosures. RoHS and Greenguard certifications confirm compliance for installations in sensitive environments.

Compatibility

The QBP-2A fits any standard 19-inch EIA rack with 1U of open panel space available for active airflow. It is designed to complement Middle Atlantic rack enclosures — including the ERK, SRSR, PD, and BGR series — but will install in any rack that accepts 19-inch rackmount accessories. Position it to exhaust heat from dense equipment zones: place below heat-generating gear in a front-to-back airflow configuration, or at the top of the rack for convection-assisted exhaust. Works alongside rack power distribution units and passive vented panels to build a complete thermal management stack. For heavier heat loads or deeper enclosures, consider pairing multiple blower panels or supplementing with a rack cooling unit.

Installation Notes

Requires a 12V DC power source — verify your rack PDU or power supply provides a compatible 12V output before ordering. The panel occupies exactly 1U; confirm available rack space in your enclosure layout. Thermostatic control is factory-configured; no user calibration is required. Mount using standard rack screws (not included with all configurations — verify package contents). RoHS compliance makes this panel suitable for thermal management deployments in EU and restricted-substance-sensitive installations. Weight is 6 lbs — factor into total rack load calculations for mobile or wall-mount enclosures.
