Fan Filter Units
Terra Universal WhisperFlow® Filter Fan Units
Overview video of Terra Universal's comprehensive portfolio of filter fan unitsTerra Universal WhisperFlow® Filter Fan UnitsOverview video of Terra Universal's comprehensive portfolio of filter fan units
Our FFU unit seamlessly merges filtration and ionization. The integrated ionizer releases negative ions, actively purifying the air. This unit enhances your environment, effortlessly capturing and neutralizing airborne particles for a cleaner space and protects sensitive parts.
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
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.
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).
Purchase replacement filters ahead of time to prevent costly operational interruptions and avoid damage to fan blowers caused by excessive backpressure from long overdue filter replacements.
