Q-PAC Multimotor Plenum Fans Achieve Seismic Certification for Critical Infrastructure

In a significant development for building safety and operational resilience, Q-PAC, a leading manufacturer of commercial HVAC fan systems, has announced that its Multimotor Plenum Fan (MPF) has received HCAI Special Seismic Certification Preapproval OSP-0875. This certification provides engineers with a pre-approved, seismically sound fan solution for vital facilities located in regions prone to earthquakes, streamlining project approvals and enhancing safety protocols.

Ensuring Operational Continuity During Seismic Events

The demand for robust, code-compliant HVAC systems in high-seismic zones is escalating, particularly for facilities where uninterrupted operation is paramount. Hospitals, data centers, emergency response centers, and laboratories all fall into this critical category. Traditional HVAC systems often require extensive, and costly, seismic reinforcement and individual review processes. The Q-PAC MPF system offers a streamlined alternative.

The MPF system – encompassing plug fan models, the supporting frame, and the integrated Q-PAC control panel – underwent rigorous testing at the University of Nevada, Reno. Certification was granted by Pre Compliance, validating adherence to both the International Building Code (IBC) 2024 and the California Building Code (CBC) 2025. This comprehensive certification signifies the system’s ability to withstand earthquake forces while maintaining essential functionality.

The Importance of Seismic Certification for HVAC Systems

Seismic certification isn’t merely about preventing physical damage; it’s about safeguarding lives and ensuring business continuity. A functioning HVAC system is crucial for maintaining safe environmental conditions within critical facilities, particularly during and after a seismic event. Without it, sensitive equipment can be compromised, medical procedures can be halted, and overall safety can be jeopardized.

The Q-PAC MPF certification simplifies the compliance process for engineers and building owners. By utilizing a pre-approved system, they can significantly reduce the time and expense associated with seismic reviews and inspections. This allows projects to move forward more efficiently, delivering essential infrastructure to communities faster.

What are the biggest challenges you face when designing HVAC systems for seismic regions? And how do you balance cost-effectiveness with the need for robust safety measures?

Beyond the immediate benefits of streamlined approvals, the Q-PAC MPF system represents a proactive approach to risk mitigation. Investing in seismically certified equipment demonstrates a commitment to resilience and responsible building practices. This commitment can also translate into lower insurance premiums and enhanced reputation.

Pro Tip: When specifying HVAC equipment for critical facilities, always prioritize seismic certification and ensure the system meets or exceeds the latest building code requirements.
