Summary
Available Certified ISO Grade Designs: ISO 6, ISO 7, ISO 8
Suitable for industries requiring frequent use of solvents and volatile organic compounds (VOCs)
Honeycomb activated carbon-equipped fan/filter unit (FFU) specialized for containing gaseous contaminants
Gas-phase filtration absorbs gaseous material at the molecular level too small for HEPA filters to capture
Activated carbon filters capture common odor-causing substances including ammonia, hydrogen sulfide, ozone
Filter adsorbs up to 7.5lb (3.4kg) of VOCs including fumes, odors, and other pollutants.
Quiet, low vibration carbon filter system; only 43 dBA measured 30 in. from unit minimizes distracting background noises
Uses a lightweight, forward-curved fan powered by a 120V 60Hz motor
Variable speed dial simplifies air balancing
Internal baffling plate and diffuser panel provide quiet, uniform air flow across the filter face
Low-profile design is ideal for cleanrooms with limited ceiling space
FDA-approved silicone sealant without harmful chemicals seals inside housing to prevent air leakage (specify acrylic urethane or other required sealant type when FFU is ordered).
Removable yellow power cord with 4-pin connector for easy installation to Terra cleanrooms (connector may be used with an optional wall plug adapter; or may be removed entirely to hard-wire the FFU)
Activated Honeycomb Carbon:
Provides effective odor control and particle filtration in critical environments.
Made from high-quality, virgin coconut shell for superior pore size distribution and maximum adsorption capacity.
Effectively removes volatile organic compounds (VOCs) like carbon tetrachloride, trichloroethane, and ethylbenzene.
Designed for high performance and low particulate shedding, these bonded carbon panels eliminate the need for downstream filters, unlike loose-fill carbon trays or disposable honeycomb filters.
Suited for HVAC systems in critical environments.
NOTE:
Customer must determine if filter leak testing is required for their application. This unit is not leak rated. If a leak test is required, units leak-tested to meet ISO 14644-3 are optionally available.
All filter sales are final; returns cannot be accepted due to the sensitive nature of HEPA filters. Leak tested filters may qualify for limited replacement if a defect is identified upon delivery.

Features and Benefits
Stainless Steel Frame, Grille, and Mesh
Carbon filter features a sanitary, sterile stainless steel frame and grille contain compressed activated carbon media with the aid of a fine mesh
VOC-Adsorbing Activated Honeycomb Carbon Filter Media
High quality compressed activated honeycomb carbon features a low wind resistance and strong adsorption capacity to filter fumes, odors, and other contaminants.
High Throughput Activated Carbon Channel Grid
Honeycomb carbon media structure creates high efficency adsorpiton without sacrificing airflow due to constrictive fiber meshes.
Full Range of Designs, Configurations!
WhisperFlow FFUs come in all styles: room-side replaceable, all-stainless steel, HEPA or ULPA filtration, EC energy-saving fans, reverse flow and more (shown: vapor filtration module with UV sanitation lamp).
Exposure to loud noises can lower the ability to focus on work and listen selectively, which may also lead to safety issues. Typical AC units can be annoyingly loud, measuring in the range of 70 dB (comparable to a vacuum cleaner). Terra’s WhisperFlow design produces far lower noise levels for a quiet environment comparable to a library. At 90 ft/min output, units measure under 50 dB from only 1 ft away (roughly 75% quieter than 70dB).
