Perforated stainless steel shield protects the FFU's sensitive filter media from damage
Heavy-duty and chemical resistant 12-gauge 304 stainless steel withstands frequent sterilization
Room-side-replaceable fan filter units feature a Gel-sealed filter and easy-open clips to allow fast filter replacement from below without breaching the cleanroom ceiling.
The stainless steel screen screws on beneath the FFU and serves as a shield to prevent accidental damage to the sensitive filter media.

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.
Gel-Filled Channel on Room-Side Replaceable Filter
Gel-filled channel on room-side replaceable filter forms a tight seal against knife edge on fan housing, allowing fast, simple filter replacement from inside the cleanroom without the need for costly cleanroom shut-down.
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
Airflow Uniformity Improves Laminar Flow
Non-uniform air speeds produce turbulence that can recirculate particles into the air stream. Unique WhisperFlow® FFU baffling system and anodized diffuser plate promotes uniform laminar airflow to minimize turbulence and effectively carry away contaminating particles.
Room-side-replaceable HEPA filters drastically simplify filter replacement to keep your cleanroom operations running smoothly. The ceiling mounted FFU features easy-open clips allowing for filter replacement from within the airlock, without dismantling the entire FFU.
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).

Energy-Efficient Lighting
Energy-efficient LED lighting panels and strips help to lower electrical costs and minimize heat build-up in temperature-controlled environments.
Power Distribution Modules for Cleanroom FFUs and Lights
UL-listed power distribution modules include all breakers, transformers and other electrical components for FFU/light connections; allows fast addition or relocation of FFUs or lights without the need for rewiring.
Ionizing Bar; 22"L, with Installation Kit, for 24 x 24 Fan/Filter Unit
Ionizing bar, mounted to Fan/Filter Unit, provides a balanced stream of ions to the work area below to neutralize static charge and prevent electro-static discharge; 22" bar shown installed on 2' x 2' FFU.
Night Service Saves Energy, Extends Filter Life!
Night service switch, shown mounted on Modular Hardwall Cleanroom panel, puts FFUs in low-energy mode during off-hours; saves 25% of fan operating costs and extends filter life.
Filter Replacement Alarm
The filter replacement alarm monitors filter backpressure and issues an alarm when filter needs replaced (requires selection of fan filter unit with challenge port, order separately).
Cord Adapter, MIN4 PL to 16AWG Power Cord for Terra Fan/Filter Unit
Four-pin power cord adapter for fan/filter unit allows connection to standard 120VAC/60Hz power receptacle.
FFU Mounting Frame; Stainless Steel
Stainless steel Fan Filter Unit (FFU) mounting frame supports FFU on drywall or other rigid ceiling material, viewed from above ceiling panel (FFU not included).
Fan Filter Unit Control System
Provides room-by-room monitoring and control of Smart WhisperFlow FFUs to maintain target pressure differentials for ISO classification; temperature, humidity and particle monitoring and data logging, as well as dynamic fan set-point control, also available.
Filter Covers Allow Ceiling Wash-Down
Ceiling panel covers allow wash-down and sterilization of cleanroom walls and ceilings without damage to filter medium; requires BioSafe glass or stainless steel wall panels, which stand up to biocides.
Challenge Port for Fan Filter Unit
Challenge port for Fan/Filter Units simplifies filter leak testing and connection of Filter Backpressure Alarm (shown with optional pressure gauge; must be ordered with FFU).
Safely Mount FFU’s Above Floor for Horizontal Laminar Airflow
The portable FFU base stand can be easily positioned to supply Class 100 horizontal laminar flow into a room or enclosure. It can also be positioned next to sensitive equipment/materials that are mounted close to the floor.
