FFU ومعدات تنقية الهواء الطرفية
الفولاذ المقاوم للصدأ مروحة وحدة مرشح
An all-welded brushed stainless steel FFU with sealed seams and cleanable hardware for sanitary, chemical-resistant or frequently wiped cleanroom ceilings.
- All-Welded Stainless Housing
- Cleanable Brushed Surfaces
- Sealed Hygienic Corners
- Room-Side Service Option
مقدمة المنتج
The stainless steel fan filter unit encloses the blower, pressure chamber and final filter in a formed 304 or 316 stainless casing. Continuous welded corner seams remove overlapping raw edges from exposed surfaces, and the brushed grain gives cleaning staff a consistent wipe direction. Stainless latches, a silicone perimeter gasket and a perforated stainless diffuser support hygienic maintenance on both the service and cleanroom sides. The construction is suitable where painted steel would be vulnerable to repeated chemical wiping, moisture or process residues.
الخصائص الرئيسية
A uniform brushed finish limits glare while leaving a smooth surface that can be wiped in a controlled direction.
Stainless latches and fasteners avoid mixed exposed materials around frequently handled service points.
An optional room-side filter arrangement permits removal without opening an inaccessible interstitial ceiling space.
مخاوف المنتج للعملاء
A hygienic FFU must tolerate repeated cleaning while preventing seams, coatings and mixed-metal hardware from becoming contamination traps.
Paint chips at service-panel edges expose corroding base metal above a critical clean zone.A stainless housing provides corrosion resistance through the sheet thickness instead of relying on a surface coating.
Folded overlaps and unsealed corners retain liquid after ceiling cleaning.Continuous welded seams and flush corner finishing remove open crevices from the exposed enclosure.
Aggressive disinfectants stain or soften ordinary painted diffusers and fasteners.A brushed stainless diffuser, latches and hardware present a consistent cleanable material system.
Ceiling access is limited in sealed pharmaceutical suites.A room-side service option allows the filter and selected fan components to be reached from the clean zone.
