Esco Airstream® Fan Filter Unit, 2' x 4', ESCO (CAT#: STEM-C-0841-ZJF)

Esco Airstream® Fan Filter Unit manufactured by Esco Micro Pte is a leading-edge unit designed to provide HEPA/ULPA-filtered laminar airflow over a specific area.
Upon receiving ambient air from the top of the module, the FFU exhausts the filtered air vertically in a laminar (unidirectional) air stream toward its base.

Cleanroom-compatible, lightweight and corrosion-resistant construction.
Centrifugal blower with permanent lubrication and direct drive.
The industry-exclusive blower technology operates at higher energy efficiency levels with a higher volume of airflow.
Patented construction technology provides superior laminar flow and product protection by ensuring uniform airflow across the entire filter face.
An energy-efficient backward-curve centrifugal blower equipped with an electronically commutated (EC) motor.
The standard blower speed controller allows for easy adjustment of the FFU speed.
Increased operator comfort and productivity through improved mounting techniques and sound insulation.
Low operating noise of fewer than 54 decibels (measured from one meter away at a standard airflow velocity of 0.45 m/s or 90 fpm with an EC blower).
Incorporated HEPA/ULPA filter (different filter types are available upon request).
During installation and transportation, the metal faceguard protects the HEPA/ULPA filter from damage.
The fan inlet guard grille ensures operator safety during installation and prevents large objects from falling into the casing and damaging it.
Various types of exterior construction materials and styles are available based on client-specific requirements and clean air applications.
An innovative, modular blower and electrical assembly that can be easily serviced and replaced at a lower maintenance cost.
The standard unit comes with three core electrical wires and an optional power cord.
