1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Common materials include stainless steel, galvanized steel, and powder-coated aluminum. Material grades such as 304 or 316L are available, with 316L recommended for corrosive environments. The choice depends on the cleanroom class and chemical exposure.
Duct diameter and airflow rate are interdependent. The directory lists duct diameters from 100 to 2000 mm and airflow rates from 500 to 5000 m³/h. Higher airflow rates require larger cross-sections. Selection must consider the required air changes per hour and pressure drop, and should be confirmed with the manufacturer.
Leakage rate (class C per EN 1507) indicates the allowable air leakage, which is critical for maintaining pressure and preventing contamination. Surface roughness (Ra 0.8–1.6 µm) affects particle accumulation; smoother surfaces reduce particle buildup, aiding cleanliness.
The fire resistance classification is A2-s1,d0 per EN 13501-1, meaning non-combustible with limited smoke and droplet production. However, verify the specific product's certification with the manufacturer, as installation and surrounding materials also affect overall fire safety.
