The Q-PAC Fan installs as easily as any traditional fan. Standard integration requires no extra programming or integrations, just a 0-10V control signal and three phase power, 50-60Hz, supporting:
What It Delivers:
Built for Real-World Conditions:
The Q-PAC Fan is purpose-built for comfort cooling environments. It’s not recommended for certain industrial or specialty applications.
| Application Name | Description | Reason |
|---|---|---|
| High Temperature Fans | Oven/kiln fans, combustion air fans, and furnace/heat-treating exhaust fans | The fan’s EC motors are rated for ambient temperatures up to 104°F (40°C). Operation above this limit is not supported. |
| Process or Material Handling Fans | Radial blade fans, paddle wheel fans, and fans designed for moving particulate-laden air (dust, chips, debris) | Q-PAC Fans are not designed for handling solid particulates or aggressive airstreams. Use in these conditions may damage the impellers or reduce performance. |
| Corrosion-Resistant or Chemical Duty Fans | Fiber-reinforced plastic (FRP), polypropylene, or epoxy-lined fans | The Q-PAC Fan is built for comfort cooling applications and does not include corrosion-resistant coatings or materials. |
| Explosion-Proof or Hazardous Location Fans | UL Class 1, Division 1 or 2 Fans and spark resistant fans (AMCA Type B or C) | The Q-PAC Fan is not explosion-proof and should not be used in classified or hazardous environments. |
| Sanitary or Washdown Fans | Stainless sanitary fans, NSF-certified fans, and IP66-rated fans | Q-PAC Fans are not rated for hygienic or washdown environments. Components are not sealed or constructed from stainless steel. |
| Ultra-low or Ultra-high Flow Fans | Residential or miniature utility fans (< 2,500 CFM) and axial fans (> 300,000 CFM) | Each Q-PAC Fan is optimized for airflows between 4,000 and 90,000 CFM, depending on configuration. Multiple fans can be combined for system-level airflow up to 360,000 CFM. |
The Q-PAC Fan supports both vertical and horizontal airflow, making it easy to match your air handler layout without rework. The Fan Frame, plug fans, and harness routing are fully compatible with either orientation, no modifications needed. Just follow standard air handler best practices: maintain recommended inlet and discharge clearances, and minimize abrupt airflow changes for optimal performance.
Width
The left-to-right span of the air handler. A single Q-PAC Fan can scale up to 150 inches wide. For larger units, multiple fans can be installed side by side to cover the full width.
Height
The vertical span from floor to ceiling inside the air handler. The Q-PAC Fan can scale up to 140 inches high to fit your unit’s layout.
Inlet Clearance | 18-20 in
The space between the Q-PAC Fan inlet and any upstream components, such as filters or coils. This gap helps ensure smooth airflow into the fan.
Discharge Clearance | 36 in
The distance from the back of the Q-PAC Fan (motors and Fan Controller) to the first downstream component, such as a duct or coil. It allows clean airflow out of the fan.
Inlet Angle | 45 degrees
The angle formed between the face of upstream coils or filters and the closest inlet cone on the Q-PAC Fan. Keeping this angle narrow improves airflow into the fan.
The Q-PAC Fan installs to a flanged surface made of mild steel or similar rigid material, between 5/8" and 1-1/4" in size. If your air handler doesn’t include a suitable flange, or if the existing flange interferes with recommended clearances, each Q-PAC Fan comes with a set of Perimeter Angles for easy, secure installation.
The knockdown version of the Q-PAC Fan ships as a kit, with components organized across multiple pallets and inclusive of the Fan Frame and Fan Controller, plug fans, and any optional accessories. With step-by-step assembly and wiring guides included, the fan can be fully assembled and ready to install in under 2 hours.
Traditional fan arrays rely on inlet backdraft dampers to stop backflow when a fan fails, but most Q-PAC Fans don’t need them. Our design eliminates prolonged airflow loss by allowing plug fans to be swapped in under five minutes. If a replacement isn’t available immediately, a supplied blank-off plate installs just as quickly to block backflow. While dampers aren’t recommended, Q-PAC can supply units that mount directly to the Fan Frame for atypical applications.
The Q-PAC Fan connects directly to your building management system or preferred controller with no extra interface required.
Optional Modbus RTU integration provides system-level feedback and control, including:
