seismic zones map HCAI Certification

These products are ideal for critical environment projects in all seismic zones.

At AJ Manufacturing, we’re proud to announce that several of our Criti-Clean Ultra fan filter units have surpassed the stringent seismic testing requirements of the California Department of Health Care Access and Information (HCAI), formerly known as OSHPD.

The following AJ products are now HCAI-certified for use on new construction and retrofit projects in seismic zones:

  • 24” x 24” Fan Filter Unit
  • 36” x 24” Fan Filter Unit
  • 48” x 24” Fan Filter Unit
  • 24” x 24” Reverse Flow FFU

Seismic zones are more common than many people think.

More than half of the United States – including the areas with the vast majority of construction projects – is in some type of seismic zone, according to the US Geological Survey. In geographic locations like these that are susceptible to earthquakes, it is critical that essential building components such as HVAC systems will remain in working order immediately following a seismic event.

This is especially critical for essential buildings such as hospitals, surgery centers and other healthcare facilities, as well as data centers, fire/police stations and many other building types. Products that are tested and HCAI certified are your assurance that critical facilities will be able to continue to operate after an earthquake.

Keeping up with building codes can be a challenge.

State and local building codes within seismic zones vary throughout the country, and are regularly reviewed and updated. So the safest way to assure code compliance for all types of projects in these areas is to specify and install HCAI-certified equipment.

Using pre-approved products simplifies seismic code compliance and minimizes risk for all stakeholders in both new construction and retrofit projects. Advantages of using HCAI-certified products include:

  • Easier code compliance
  • Faster approvals
  • Faster building occupancy
  • Reduced liability
  • Increased value for the building owner

Our HCAI-certified fan filter units have been thoroughly analyzed, tested and certified by an independent third party. You can download the full report here and watch a video of one of our shake tests here.
