Features and Benefits
Products Compliant With Your ISO Rating
Provide Terra with your desired ISO rating. We will tailor the product to meet your rating and certify it with the serial numbers appended to your invoice, to be included in your compliance package.
UL 900 Certified for Fire Safety
HEPA and ULPA filters are UL certified for UL 900 to meet local and state fire safety requirements for most applications. The standard covers requirements and tests for allowable combustibility and amount of smoke generated.
Diffuser Panel Promotes Air Flow Uniformity and Protects Filter Integrity
Unlike other manufacturers, Terra’s FFUs include a unique perforated panel beneath the filter, acting as a shower head, to guarantee filter protection and laminar air flow uniformity, which prevents localized air swirling, particle build-up and turbulence.
Protect Against Contaminants and Pathogens
HEPA and ULPA filters help capture many bacteria, viruses (COVID-19), and mold spores that contribute to a host of infections for both humans and plant/animal tissue cultures
Long Running FFU Motors
Terra’s filter fan unit motors are rated for 5 years of continuous, 24/7 operation, if the HEPA filters are consistently replaced. To accurately monitor your HEPA filter’s saturation levels, purchase Terra’s audible and visual filter replacement alarm system.
