AIR HANDLING UNITS  |  Standard Specifications — Recirculating Fan Cabinets Fan cabinets are constructed of 18-20ga Galvanized Steel with 14-16ga internal channels and braces. Cabinets are supplied with removable access panels for serviceability of motor and blower(s). Fan cabinets can be furnished with provision for suspension or mezzanine mount applications. Standard configuration is back inlet, top horizontal discharge. Other configurations are available. Cabinets are lined with 1″ thick insulation to minimize sound and loss of temperatureStandard insulation is a non-shedding liner, secured to the internal surfaces of the fan cabinet with approved adhesive. All exposed edges of the liner are sealed. Internally Isolated Motor Blower Assembly Standard configuration is a single motor and a single blower installed on a common frame which is mounted to the cabinet with adjustable spring isolators. Multiple blowers with a common shaft and motor are available for a lower profile cabinet.

Units built to required CFM with capacity to overcome customer specified system static pressure. Standard Prefilters are 2″ or 4″ thick, 30% ASHRAE supplied in a face load Prefilter frame for ambient return air. Chilled water or DX coils can be added with or without drip pans for temperature and/or Cabinet: Painted steel, Stainless Steel Construction Configuration Discharge: Bottom Horizontal, Bottom, Top Inlet: Side, Bottom, Top [Click here for a PDF of this content.]HomeCleanroomsCleanroom & BSL SolutionsCleanroom Integrated Project DeliveryBIM & Cleanroom DesignPharmaceutical CleanroomsUSP797 Pharmacy CleanroomElectronics CleanroomsNanotechnology CleanroomsTrace Metals CleanroomsOptics CleanroomsEducation & Research Labs & CleanroomsBiological Safety ContainmentMedical Device Manufacturing CleanroomsPrinted Circuit Board CleanroomsCleanroom Design DecisionsCleanroom Ceiling SystemsCleanroom DoorsCleanroom FlooringCleanroom Mechanical SystemsCleanroom Air HandlingCleanroom Facility ManagementCleanroom ElectricalCleanroom Commissioning & CertificationCleanroom ValidationCleanroom HVACCleanroom FiltrationCleanroom Change Room OptionsCleanroom Material Pass ThroughsCleanroom Air ShowersCleanroom & Lab CaseworkHEPA WorkstationsPortable OptionsCleanroom Design ConsiderationsWater SystemsCleaning MaterialsFire

Home » Cleanrooms » Cleanroom Design Decisions » Cleanroom Air Handling One of the largest sources of energy use in a Cleanroom is the mechanical systems to distribute the air required for dilution. The higher the static pressure of a air moving system, the higher the energy costs to push the air through the system.air handling unit controls On simple Cleanrooms, this can be the Fan Filter Unit (FFU), which combines the HEPA Filter and an integral fan. These are convenient, low cost, readily available, and simple to install. More Information on FFU’s can be found in our Filtration section. The alternative is an Air Handling Unit (AHU) which would act as the source of air for Terminal HEPA filters. Air Handling Systems can be simple, just a fan, and a pre filter, or complex, allowing levels of filtration, and various methods of conditioning the air.
