Cleanable with compressed air or high speed blower

A fan filter unit (FFU) is a type of motorized air filtering equipment. It is used to supply purified air to cleanrooms, laboratories, medical facilities or microenvironments by removing harmful airborne particles from recirculating air The units are installed within the system's ceiling or floor grid. Large cleanrooms require a proportionally large number of FFUs, which in some cases may range from several hundred to several thousand. Units often contain their own pre-filter, HEPA filter and internally controllable fan air distribution.

Design
FFUs are typically manufactured in 4' x 2', 3' x 2', or 2' x 2' steel housings, which can be placed in ceiling grid bays of similar dimensions Units often contain a pre-filter as well as a HEPA (high-efficiency particulate air), ULPA (ultra-low particulate air) or other MERV (minimum efficiency reporting value) filter. A motorized fan is used to pull air through the filters for distribution to rooms or enclosed work stations such as hoodsFan speed is typically controlled via a step-wise or rheostat motor adjustmentDesired cleanliness levels determine the filter used: HEPA filters remove particles 0.3 um or larger at 99.99% efficiency, while ULPA filters remove particles 0.12 um or larger at 99.999% efficiency FFUs are engineered for laminar air flow, as is required in critical environments. Controlled air flowing in a uniform direction and speed (carrying microparticles) is cleaner than turbulent air that flows in multiple directions or at inconsistent speeds. Eddies created by turbulent air cause contaminating microparticles to settle on clean surfaces.

Uses
4' x 2' or 2' x 2' FFUS are designed to be placed in ceiling grid bays with similar dimensions. Ceiling grids with standard size bays that match FFU dimensions are used to construct cleanrooms. Depending on the cleanliness requirements of the controlled space, more fan filter units can be added to the grid in order to meet ISO standards for airflow velocity and air changes per hour. FFUs can be used in place of a more conventional recirculating air unit such as a ducted or plenum air system. As FFUs require space above the ceiling grid (13" for the FFU module plus another 1–2 feet of "empty" air-filled space), plenums are commonly used for clean rooms with height restrictions; they are the only air systems that work in layouts with smaller internal floor dimensions Additionally, when less than 20 filters are installed in a room, a fan- powered HEPA, FFU is generally considered to be less expensive than a more conventional ducted supply system. When a microenvironment of clean air is required, FFUs can be used to construct enclosed work spaces, or laminar flow cabinets. Applying the same principle as the larger cleanroom grid, FFUs can be placed directly in a free- standing grid above the space that requires clean air. In fact, this approach is also used for silicon wafer etching in the semiconductor industry.
FFUs can be used in place of a more conventional recirculating air unit such as a ducted or plenum air system. FFUs are often used because of height restrictions in the space; they are the only systems that work in setups with smaller internal floor dimensions. Additionally when less than 20 filters are involved, a fan powered HEPA, FFU design is generally considered to be less expensive than a more conventional ducted supply system.

Also called clean air tent, these units serves the purpose of relatively a smaller clean room and are available in a ready to assemble configurations. These units can be moved from place to place & finds extensive applications in the areas of automatic filling stations & packing sections of a pharmaceutical industry, assembling sections in the electronic industries, post operative patient care in hospitals and many other places here the product safety and processing, demands a high level of cleanliness around and where the process activity does not emit any level of contaminants into the local atmosphere.

Clean air tents are generally used within a CLASS 10000 clean rooms, in which a specific area where the manufacturing & processing activity is taking place. The entire ceiling is provided with HEPA filters and at least 600 air change per hour is maintained to provide an absolutely clean & CLASS 100 condition inside within minutes after the system is switched on. This type of clean air tents are fabricated in various sizes to accommodate the requirement of the site conditions.The complete structure is made of heavy duty ERW square tabular sections. The strong castors with brake, provided at the bottom enables the total unit to move from place to place. These types of work stations are useful for small volume filling of the vials and in convey or type filling sealing machines and in bottling & sealing of IV fluids etc., in the pharmaceutical industries and in the manufacturing of medical gloves & instruments etc.

Pass through box is designed to minimize traffic and contamination entry into the clean room. Enables parts, tools and other work items to be passed to and from the room.

Unit acts as an air lock device preventing ambient air from entering, or clean air from exiting the clean room.
