Diffuser Panel Promotes Air Flow Uniformity and Protects Filter Integrity: Unlike other manufacturers, Terra's FFUs use a unique perforated panel like a shower head beneath the filter, to protect the filter and make laminar air flow more uniform by preventing 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.
COVID-19 Infection Control: Terra's ceiling-mounted reverse-flow ducted fan filter units can convert the room into a negative pressure isolation room.
Dust Collector Pan Helps Prevent Contaminants from Re-Entering Cleanroom: Removing the collector pan with accumulated dust particles easily from the filter for cleaning and maintenance will prevent contaminants from re-entering the cleanroom.
Complete Project Transparency: Terra is dedicated to complete transparency on project status, shipment tracking, and installation scheduling.
Wide Selection of Global Shipping Options: Terra offers a broad range of global shipping services including door-to-door and white glove delivery.
Network of International Reps: Terra Universal has an international network of more than 20 local sales reps trained to provide comprehensive service for all Terra Universal's products.
