Q-PAC, a leader in the design and manufacturing of commercial HVAC fan systems, offers the Q-PAC Multimotor Plenum Fan (MPF), which is now covered under HCAI Special Seismic Certification Preapproval OSP-0875, giving engineers a seismically certified fan option for critical facilities and high-seismic regions. Q-PAC MPF is a code-compliant solution for new construction and retrofit air handler projects that must meet International Building Code (IBC) and California Building Code (CBC) seismic requirements. The complete MPF system, including all plug fan models, the frame, and the Q-PAC control panel, was tested at the University of Nevada, Reno, and certified by Pre Compliance for IBC 2024 and CBC 2025. The certification targets essential facilities such as hospitals, laboratories, and other critical infrastructure. It demonstrates that the fan system can withstand earthquake shaking and maintain operation at the specified seismic demands, providing a clear, code-based path that reduces risk and back-and-forth during plan review and inspection.
