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

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.

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.

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).

Smart Fan Filter Unit with EC Motor

Smart WhisperFlow® Fan Filter Units are quiet, energy-efficient and easily adjustable, either manually or via automatic smart console, for centralized fan speed control and cleanroom pressure balancing.

  • 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.
  • 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).
  • 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.
  • Challenge Port; for Fan/Filter Unit

    Challenge port for Fan/Filter Units simplifies filter leak testing and connection of Filter Backpressure Alarm (shown mounted on SS FFU, order separately).
  • 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.
  • 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).
  • 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.
  • 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.
