Middle Atlantic DUCT COOL SYSTEM 135 CFM INCLUDES 25ft. INSULATED DUCT - DUCT-COOL-1PT

Middle Atlantic DUCT-COOL-1PT Quiet-Cool Duct Cooling System

Overview

The Middle Atlantic DUCT-COOL-1PT is an active duct cooling system delivering 135 CFM of directed airflow through 25 feet of insulated duct — purpose-built for AV racks and equipment enclosures where you need to move heat out of the cabinet without relying on passive convection alone. If you're running densely loaded racks in a closet, behind millwork, or in a finished room where equipment heat is a recurring reliability concern, the DUCT-COOL-1PT (often searched as DUCT COOL 1PT) gives you a defined, routable cooling path rather than hoping ambient air exchange is enough.

The 120 VAC active blower doesn't require a separate DC power supply or controller — plug it into any standard outlet in the enclosure and route the 25-foot insulated duct to wherever the heat needs to go: an exterior wall vent, a ceiling plenum, or an adjacent utility space. At 10 inches wide, 10.4 inches tall, and 11.88 inches deep, it fits within the footprint of a standard Middle Atlantic rack bay without dominating the enclosure.

Key Features

• 135 CFM Active Airflow: 135 cubic feet per minute is meaningful air movement for a single-rack thermal solution. Passive convection in a sealed or semi-sealed enclosure typically manages far less — this blower adds forced circulation that actually displaces heated air rather than just redistributing it. For a fully loaded 10U–14U rack in a confined space, that's the difference between components operating at rated temperature ranges and thermal throttling.
• 25-Foot Insulated Duct Included: The insulated duct run lets you exhaust warm air to a point outside the equipment zone — critical when the rack is in a finished room or AV closet where you can't just blow hot exhaust back into the same cubic footage. At 25 feet, you have enough reach to route through a wall chase or ceiling cavity without splicing additional duct.
• 120 VAC Power Input: Runs directly off a standard North American outlet — no low-voltage transformer, no 24V bus tap, no additional power distribution required. This simplifies wiring in retrofit installs where adding a DC rail isn't practical.
• Active (Blower-Driven) Component Type: Active cooling moves air on demand regardless of temperature differential. Passive systems (vented panels, chimney baffles) depend on a meaningful delta between inside and outside temperatures. In summer months or in rooms without dedicated HVAC, that delta shrinks — an active blower maintains airflow regardless of ambient conditions.
• Compact Chassis (10 × 10.4 × 11.88 in): Sized to mount within a standard Middle Atlantic rack bay. The 10-inch width fits comfortably in most rack widths, and the 11.88-inch depth keeps it from protruding beyond the rear rail plane in deeper enclosures.
• Shipping Weight of 29 lbs: The weight reflects a complete, ready-to-install system — blower unit plus the full 25-foot duct assembly. No field sourcing of compatible duct or adapters required; the matched kit ships together.

Integration and Compatibility

The DUCT-COOL-1PT is a Middle Atlantic product and integrates naturally with Middle Atlantic rack enclosures, ERK series racks, and L-Series furniture. The 120 VAC input pairs directly with Middle Atlantic's power distribution units (PDUs) already common in these builds, so the cooling system draws from the same managed outlet strip as the rest of the rack payload.

For integrators specifying Middle Atlantic rack and enclosure systems, this unit drops into the thermal management plan without requiring a separate cooling infrastructure discussion. It's also compatible with third-party enclosures where a 10-inch bay opening and a routable duct exit are available.

When specifying rack cooling solutions for multi-rack deployments, evaluate whether a single DUCT-COOL-1PT per enclosure is sufficient or whether high-density loads require supplemental top-mounted exhaust fans in addition to active duct cooling. For AV rack accessories and rack power distribution, the 120 VAC input aligns with standard PDU outlets already present in most enclosures. Integrators managing larger deployments should also review rack enclosure planning guides to confirm airflow path routing before finalizing duct exit locations. For broader thermal strategy across distributed AV closets, pair this unit with a rack power management solution that provides outlet-level current monitoring — early warning before thermal events become outages.

Frequently Asked Questions

Q: What airflow does the DUCT-COOL-1PT deliver, and is it enough for a fully loaded rack?

A: The DUCT-COOL-1PT is rated at 135 CFM. For a moderately loaded single rack in a confined enclosure, 135 CFM of directed airflow is generally sufficient to remove heat before it accumulates to damaging levels. Very high-density loads (multiple power amplifiers, dense switching, UPS in discharge) may benefit from supplemental exhaust fans at the top of the enclosure in addition to this unit.

Q: What power source does the DUCT-COOL-1PT require?

A: The unit runs on 120 VAC — a standard North American outlet. No low-voltage transformer or DC bus connection is needed. It connects directly to any outlet in the rack's power distribution unit.

Q: How long is the duct included with the DUCT-COOL-1PT?

A: The system includes 25 feet of insulated duct. That length is typically enough to route through a wall chase or ceiling cavity to an exterior vent or adjacent utility space without requiring additional duct sections.

Q: Will the DUCT-COOL-1PT fit in a standard Middle Atlantic rack bay?

A: Yes. The unit measures 10 inches wide, 10.4 inches tall, and 11.88 inches deep — sized to integrate within standard Middle Atlantic rack bay dimensions without protruding beyond the enclosure footprint.

Q: Is the DUCT-COOL-1PT an active or passive cooling system?

A: Active. It uses a powered blower to move air, which means it delivers consistent CFM regardless of the temperature differential between inside and outside the enclosure — unlike passive vented panels that depend on convection.

Q: Does the included duct need to be insulated separately, or is it insulated as shipped?

A: The duct included with the DUCT-COOL-1PT is already insulated. No additional wrapping is required before installation.

Jerry Tildsen

The spec that defines this unit's deployment value is simple: 135 CFM through 25 feet of insulated duct. The DUCT-COOL-1PT exists because AV integrators kept losing reliability margin in finished-room rack installs where there's no clean path for natural convection — the closet gets hot, the gear throttles or fails, and you're back on-site. Routing 25 feet of insulated duct to a ceiling plenum or exterior vent is a solved problem with this kit; it's not something you want to figure out ad hoc in the field.

Technical Highlights:

• 135 CFM Blower: Enough to maintain thermal headroom in a single enclosure under typical AV loads — control processors, matrix switchers, amplifiers. Not a data-center-class solution, but correctly sized for the AV closet use case it's built for.
• 25 ft Insulated Duct: The insulation matters — bare duct re-radiates heat into whatever space it runs through. Routing warm exhaust through a finished ceiling without the insulation defeats the purpose of moving it out of the rack in the first place.
• 120 VAC Input: Direct connection to the rack PDU, same circuit as everything else in the enclosure. No secondary power infrastructure, no low-voltage conversion step, no additional labor cost to bring in a separate circuit.

Deployment Considerations:

• Plan the duct exit path before mounting. The 11.88-inch depth fits the rack bay, but the duct needs a 90° exit route — confirm your enclosure has a rear or side knockout aligned with where you're routing. A sharp duct bend immediately behind the blower kills CFM efficiency.
• At 29 lbs shipped, the full kit is heavier than it looks on paper — account for that when placing this in a wall-hung enclosure near its weight limit. The blower unit alone is lighter, but the duct assembly adds up.

This unit earns its place in any finished-room AV installation where the rack lives behind cabinetry or in a dedicated closet with limited passive airflow. If your install has an open equipment room with free-air convection and ceiling clearance, a simpler passive approach may suffice — but for the sealed-closet scenario, the DUCT-COOL-1PT is the right tool.
