Perimeter Angles are a set of 14-gauge galvanized steel adapters that form a mounting flange, making it easy to install the Q-PAC Fan in any air handler.
Control Panels and Accessories
Premium Control Panel
The Q-PAC Premium Control Panel is a 508A-rated panel that delivers advanced control, monitoring, and protection for Q-PAC Fans all in one enclosure. It supports multiple control modes, real-time performance monitoring, and BACnet MS/TP or IP communication. Rated to UL 508A standards, it’s built for both indoor and outdoor use and engineered to handle the most demanding HVAC applications.
A rotary handle mounted externally and linked to a fused disconnect, providing secure, lockable isolation for safety during maintenance.
Provides three modes of operation: HAND for manual control, AUTO for automatic control via the building management system, and OFF for complete shutdown.
Provides local control and monitoring; optional hinged access panel on Type 4 (outdoor enclosures) for added weather protection.
Basic Control Panel
The Q-PAC Basic Control Panel provides essential control, monitoring, and protection for Q-PAC Fans in a single enclosure. It supports local operation along with basic start/stop functions and safety circuit integration. Rated to UL 508A standards, it’s available for both indoor and outdoor installations and suited for a wide range of HVAC applications.
A rotary handle mounted externally and linked to a fused disconnect, providing secure, lockable isolation for safety during maintenance.
Provides three modes of operation: HAND for manual control, AUTO for automatic control via the building management system, and OFF for complete shutdown.
The Q-PAC Basic Control Panel does not include advanced monitoring or system feedback capabilities. For expanded functionality, including real-time performance data, multiple control modes, and network integration, consider the Q-PAC Premium Control Panel.
Fused Disconnect
Q-PAC offers Schneider’s VisiPacT heavy duty, fused safety switch, a component built for real-world reliability. These switches isolate power safely during daily operations and emergencies, with a key role as a lockout line-of-sight disconnect. Tested to triple the NEMA standard, they’re ready for the rough realities of commercial and industrial environments.
A quick make/break mechanism ensures fast, reliable operation, while the built-in viewing window gives you clear visual confirmation of switch position.
Blocks access to live components by locking the cover when the switch is ON. And when the cover is open, it prevents the switch from being turned back ON.
The fused disconnect serves strictly as a local power shutoff for the fan install. It doesn’t handle fan control or communication; for that, the Q-PAC Fan requires a separate controller connection. Or consider upgrading to a Q-PAC Premium or Basic Control Panel for integrated functionality.
Perimeter Angles
Perimeter Angles include vertical and horizontal members that nest to form a nearly continuous mounting surface, allowing up to ½" of dimensional flexibility for a precise, adaptable fit.
Every Q-PAC Fan ships with Perimeter Angles and all required hardware, ensuring a complete, ready-to-install system. Pre-punched flanges and self-drilling screws simplify mounting for a quick, consistent install every time.
Coupler
The coupler joins two Q-PAC Fans into a single structural bulkhead for larger systems, using a 14-gauge galvanized steel channel and flanged adaptor for strength and stability.
The coupler’s side flanges create an intermediate mounting surface for the Q-PAC Fan Frame, fastening first to the Perimeter Angles, then to the installed fan, streamlining the setup for the next unit.
Couplers come standard with any system using two or more Fan Frames, and can support up to four fans joined together to handle high-airflow demands with ease.
