Terra Universal offers an extensive portfolio of COVID-19 contamination control products for employee protection, surface disinfection and product sterilization COVID-19 Contamination Control Products by Terra Universal As personal and professional lives shift dramatically in response to the COVID-19 pandemic, businesses are searching for methods to reduce the transmission risk of COVID-19 in the workplace. Terra Universal offers an extensive product portfolio to support employee protection, surface disinfection and product sterilization. Let’s take a closer look at two products designed to control the spread of COVID-19.

Features and Benefits

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

COVID-19 Infection Control

Terra’s in-stock ceiling-mounted reverse-flow ducted filter fan units convert any space into a negative pressure isolation room

Dust Collector Pan Helps Prevent Contaminants from Re-Entering Cleanroom

Collector pan accumulates dust particles that dislodge from the HEPA filter, preventing contaminants from re-entering the cleanroom. Collector pan integrates with bag-in/bag-out (BIBO) systems and is easily removed for cleaning or maintenance.

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. Each product is safely packaged in a heat-treated wooden crate that meets international shipping standards.

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

Catalog of CE-Marked Products

Terra offers over 1,700 CE-marked products configured for international voltage requirements

Products Compliant With Your ISO Rating

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