The Q-PAC Fan is a smart, self-contained system. It’s one device with everything built in. The Fan Controller is the brain, handling power, control, and live feedback through a single connection. You get airflow readings, fan status, and motor-level diagnostics without touching a single motor. No extra wiring. No separate panel. And because it’s fully integrated, it ships ready to go, either fully assembled or as a kit in knockdown.
The Q-PAC Fan runs like a team, with every motor working in sync under the Fan Controller’s direction. Each one is modulated individually, but together they deliver smooth, balanced airflow across the array. If a motor trips, built-in branch circuit protection keeps the system online. The rest step up automatically to hold your target. No manual intervention. No ripple effect. Just steady, resilient performance that doesn’t miss a beat.
True resiliency is airflow that doesn’t quit. Single-motor fans? They guarantee downtime unless you’ve stocked pricey spares. Fan arrays? Only as reliable as their control panels. The Q-PAC Fan flips that script. Lose a motor and the Fan Controller pushes the others harder to stay on target. Lose the controller and the fan still runs. It’s built to keep you operational when things go sideways. No downtime. No excuses.
At Q-PAC, fan performance is measured by what happens in your system, not just on a spec sheet. Spacing between impellers, the air handler’s layout, and the interplay between fans all shape output across the operating range. Our new airflow tunnel tests for every variable, right down to motor failure. It’s performance you can see, trust, and count on when it matters.
Smart Fan Technology
The Q-PAC MPF is a smart fan, and the Fan Controller is the brain that makes it possible. It talks to every motor, tracks performance, measures airflow, and keeps tabs on system health with built-in alarms. From simple analog wiring to Modbus connectivity, it’s built for today with even more capabilities coming tomorrow.
Adaptive Frame
Most fan arrays are built in fixed increments, leaving gaps that must be blanked off in the field to finish the pressure wall. The Q-PAC Fan is different; its sheet metal panels are custom-fabricated for every order, allowing it to serve as the air handler’s pressure wall with no extra fabrication. It mounts directly to the existing flange, or with included Perimeter Angles if no flange is present.
Installation options - Assembled or Knockdown
New AHU or retrofit, the Q-PAC Fan delivers. Backed by almost ten years of field-proven performance, its interlocking panels and engineered hardware ship in palletized kits with simple instructions, allowing on-site assembly in just hours. Need it even faster? Order it factory-assembled and ready to drop into place. No extra fabrication, no wasted time – just install and go.
Automated Design
Q-PAC Fans are designed in seconds, not days. Our parametric design engine optimizes motor selection and engineers the supporting Fan Frame for any application. Users simply enter airflow, dimensions, and power supply, and the system instantly generates a recommended fan with complete performance details. This eliminates the delays of manual array design and avoids the compromises of fitting a blower from a limited catalog. You get exactly the fan you need, and you get it fast.
The Fan Controller is the single connection point for both power and control with no field wiring required. Each motor plugs in with pre-wired harnesses that snap directly into the Controller. It’s fast, clean, and built to eliminate on-site guesswork.
Built to order, the Q-PAC Fan’s Frame matches your cabinet dimensions. The Fan Frame can scale up to 150 inches wide and 140 inches tall.
Electrical components fail. It’s not a matter of if, but when. That’s why the Q-PAC Fan is built for fast, no-fuss replacement: just a few bolts and plugs, and you’re done in minutes. The team is pushing toward a future of recyclable motors and impellers, with a constant focus on reducing labor, weight, and—most of all—cost. Because the most robust fan isn’t the one that eliminates failure, but the one built to handle that failure with 100% resiliency.
