Features and Benefits

Mini 12”x12” FFU for Small Enclosures

Terra’s Mini HEPA FFU removes airborne contaminants to enhance contamination protection in small enclosures.
The LED status indicator glows continuously when the FFU is plugged in and turned on to confirm the system is operational. Variable speed control dial allows for precise air flow control. Durable and corrosion resistant 304 stainless steel housing resists alcohol-based cleaning agents.

Mini FFU Size Comparison

The Mini FFU fits a compact 12”x12” footprint. Perfect for small enclosures such as storage cabinets, gloveboxes, and pass-through chambers. Single pass HEPA-filtration adds an extra layer of protection against particle and microbe contamination.

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.

Low Profile FFU Design Only 8-Inches Tall

Low profile fan filter units are ideal for cleanrooms with height constraints. They stand 8 inches tall, compared to a standard FFU that stands 13.5 inches tall. The variable speed control dial allows for precise air flow control.

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.

Clean and Durable Powder Coat Finish

Terra’s signature white powder coat finish provides a high quality, durable barrier to protect against corrosion, plus a clean and attractive aesthetic. The advanced heat-fused formulation exceeds ASTM and ISO paint standards to resist chipping, scratching, fading, and wearing.

Network of International Reps

Terra employs an international network of more than 20 local sales reps trained to provide comprehensive service on Terra's complete catalog of products

Wide Selection of Global Shipping Options

Terra offers a broad range of global shipping services including door-to-door and white glove delivery. Each product is safely packaged in a heat-treated wooden crate that meets international shipping standards.

Products Compliant With Your ISO Rating

High-capacity, durable, ISO-compliant system rated for thousands of operating hours.
