HEPA and ULPA filters capture and mitigate airborne particles, as well as pathogens including Rhinoviruses, Influenza, SARS-CoV-2, and RSV. Filters also combat aerosolized bacteria like C. Difficile, a prevalent cause of hospital-acquired infections.
Ducted filter unit provides HEPA- or ULPA-filtered air to an enclosure. WhisperFlow baffling system and anodized aluminum diffuser ensure uniform face velocity (requires remote air handler; 2' x 2' model shown).
Diffuser Panel Promotes Air Flow Uniformity and Protects Filter Integrity

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.
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.
This FFU provides ULPA filtered and heated air. It features a temperature controller for easy adjustment up to 100F with alarm options. The interior includes two stainless steel heaters to quickly dissipate heat into the air.
