Fan Filter Unit, Narrow, 16" x 48", HEPA, 240 V, Powder-Coated Steel, WhisperFlow, Terra Universal (CAT#: STEM-C-0152-ZJF)

The Narrow WhisperFlow® Fan Filter Unit 6601-1648-H-220 manufactured by Terra Universal provides a steady laminar flow stream of HEPA filtered air to the area below the mounted unit.
High Efficiency Particulate Air (HEPA) Filter: 99.99% efficient at 0.3µm particle diameter.
AC 3-speed blower motor makes it easy to realize low, medium and high speed wind speed regulation.
FDA-approved silicone sealant has good sealing, high safety and durability.
Internal baffling plate and diffuser panel make the air flow quiet and even.
Threaded (1/4-20 UNC) inserts on corners make the unit easy to hang and mount.
MERV 7 pre-filter which is 30% ASHRAE rated helps to extend the service life of HEPA filter.
Low-profile design is compact and takes up less space, ideal for cleanrooms with limited ceiling space.
Removable yellow power cord with 4-pin connector guarantee the convenience and soundness of the unit's installation to cleanrooms.
Filters are leak tested in accordance with IEST standards and meet UL 900.

Diffuser Panel Promotes Air Flow Uniformity and Protects Filter Integrity: Unlike other manufacturers, Terra's FFUs use a unique perforated panel like a shower head beneath the filter, to protect the filter and make laminar air flow more uniform by preventing 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.
Long Running FFU Motors: Terra's filter fan unit motors can operate continuously for up to 5 years if the filter is changed frequently.
Airflow Uniformity Improves Laminar Flow: Unique WhisperFlow® FFU baffling system and anodized diffuser plate minimize turbulence and effectively carry away contaminating particles by making laminar airflow more uniform.
Clean and Durable Powder Coat Finish: Terra's signature white powder coat finish balances high quality with beauty. The advanced heat-fused formulation exceeds ASTM and ISO paint standards to prevent all kinds of damage.
WhisperFlow Quiet Operation Reduces Distracting Background Noise: Noise can reduce concentration at work and even lead to safety accidents. Unlike other AC units with 70 dB of noise, Terra's WhisperFlow design has library-level noise levels. At 90 ft/min output, units measure under 50 dB from only 1 ft away (roughly 75% quieter than 70dB).
Highest Standards For Electronic Components: Terra's electronic components are designed and built to the highest standards required by defense and semiconductor industries for long life and high quality.
Catalog of CE-Marked Products: Terra offers over 1,700 CE-marked products configured for international voltage requirements.
