Ürün tanıtımı

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, is distributed through the plenum and passes evenly across the full filter face before entering the clean zone. The drop-in perimeter is sized for common modular ceiling grids, while separate access to the fan and filter supports routine inspection without dismantling adjacent ceiling panels.

Ana Özellikler

A centered centrifugal blower supplies the pressure needed to overcome the prefilter, final filter and diffuser resistance.

Internal baffles distribute air across the mini-pleat pack instead of concentrating velocity directly below the fan inlet.

The perforated downstream face protects the filter media and moderates the outlet air pattern.

A gasketed ceiling flange limits bypass between the FFU frame and the supporting grid.

Müşteri Ürün Sorunları

A standard FFU must provide repeatable clean air over a ceiling bay while remaining straightforward to install, balance and maintain.

A central fan jet creates high velocity in the middle and weak airflow near the filter corners.A formed pressure plenum and internal distribution baffle spread inlet air before it reaches the filter pack.

Air leaks around the module perimeter allow unfiltered ceiling-plenum air to enter the clean zone.A continuous closed-cell gasket seats against the ceiling grid and closes the perimeter bypass path.

Dust loading in a coarse prefilter shortens final-filter service life and raises fan power.A removable top intake prefilter captures larger debris before it reaches the high-efficiency media.

Different ceiling bays require inconsistent on-site adapters and leave uneven module spacing.Standardized square and rectangular footprints fit common cleanroom T-grid layouts with repeatable support points.
