FFU et équipement de purification de l'air terminal
Unité de filtre de ventilateur standard
A self-contained ceiling module for particle-controlled supply air, with an intake prefilter, blower and replaceable final filter.
- Blower intégré et filtre final
- ZFormat modulaire Ceiling-Grid
- Intake Prefiltration
- Top-Side Fan Access
Introduction de produit
The standard fan filter unit packages a backward-curved centrifugal blower, shallow pressure plenum, mini-pleat final filter and perforated diffuser in one ceiling-mounted housing. Air enters through the top prefilter, passes through the distribution plenum and final filter, and leaves through the downstream face. A perimeter flange and gasket form the interface with the supporting grid. The fan is serviced from above; the final-filter replacement route depends on the selected filter-release configuration.
Key Features
Les déflecteurs internes distribuent l'air à travers le pack mini-plets au lieu de concentrer la vitesse directement en dessous de l'entrée du ventilateur.

Des solutions pour votre application
Selecting a standard FFU involves the ceiling interface, airflow balance and access to consumable filters.
Air reaches the filter unevenly from the fan outlet.The distribution plenum and baffle spread the incoming air; face measurements during balancing check the installed result.
A poor ceiling fit leaves gaps around the module.Match the flange and gasket to the grid bearing surface, then inspect the perimeter seal after the module is seated.
Prefilter dust loading reduces the airflow available to the clean zone.Keep the removable intake prefilter accessible for inspection and service, and recheck airflow when it is cleaned or replaced.
Final-filter replacement is difficult in a closed ceiling void.Choose the filter-release arrangement before ordering; clean-side release is an option rather than a feature of every module.

Selection and Installation
Size the ceiling bay and service space
Send the ceiling-grid opening, support detail, available plenum height and intended access route. Identify whether the unit draws from a common plenum or connects to ductwork. The module envelope, flange bearing and prefilter access need to suit the actual ceiling, not just its nominal grid size.
Specify the operating point
State the required airflow and available inlet conditions, together with the selected final filter. Request input power and sound data at that same duty point; motor nameplate power is not a substitute for operating consumption. For comparison within the range, review the locally controlled AC FFU et EC-motor FFU without assuming that this standard version uses either drive.
Identify what is included
The described module contains the housing, blower, intake prefilter, final filter and diffuser. Specify the required supply voltage, phase and frequency, final-filter grade, controller and cable connection in the enquiry. Group interfaces and clean-side filter release are choices, not implied standard equipment.
Plan balancing and maintenance
Match the fan-control method to any upstream airflow control. Measure supply airflow after installation and after changes to the filter or fan setting. Keep the top fan and prefilter service route clear; choose clean-side filter release where overhead access is impractical. Isolate electrical power before servicing, protect filter media from handling damage and verify the replacement filter seal before returning the area to use. The FFU is a room air-supply component, not a complete ventilation or containment system.
