FFU et équipement de purification de l'air terminal
AUnité de filtre de ventilateur en acier revêtu de zinclu
A durable FFU using spangled aluminium-zinc coated steel to combine the stiffness of formed sheet with better atmospheric corrosion resistance than untreated galvanized housing.
- Aluminium-Zinc Coated Housing
- Visible Protective Spangle
- Folded Lock-Seam Construction
- Cost-Effective Corrosion Resistance
Introduction de produit
The Aluzinc-coated steel fan filter unit uses aluminium-zinc metallic-coated sheet for the plenum, access covers and formed mounting edges. The characteristic crystalline spangle remains visible, making the housing easy to distinguish from brushed stainless steel. Folded lock seams create rigid edges without extensive welding, while zinc-compatible clips and passivated fasteners limit dissimilar-metal contact. The material is intended for clean ceiling voids where a natural metallic finish and improved atmospheric corrosion resistance are required without the mass and cost of an all-stainless enclosure.
Key Features
A formed lock-seam casing gains stiffness from folded edges while keeping the module comparatively light.
The natural metallic surface eliminates a paint layer that could be scratched during overhead handling.
Compatible clips, screws and gasket retainers reduce avoidable galvanic contact at service points.
Préoccupations du client produit
A metallic FFU housing must resist routine plenum humidity and installation scratches without introducing unnecessary stainless-steel cost.
Paint damage during ceiling installation exposes ordinary steel edges before the room is commissioned.The metallic aluminium-zinc coating remains protective even where no decorative powder coating is applied.
A heavy stainless enclosure adds load to a lightweight modular ceiling grid.Formed Aluzinc sheet provides useful casing stiffness at a lower enclosure mass.
Condensation above the ceiling creates white rust and staining on basic galvanized panels.The aluminium-zinc coating improves atmospheric corrosion resistance in normal service conditions.
Mixed clips and fasteners leave localized corrosion marks around removable covers.Zinc-compatible hardware and isolating washers maintain a more consistent material interface.
