2 companies list 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.
According to the directory data.
Common materials include stainless steel, brass, aluminum, and engineering plastics. For corrosion-resistant applications, stainless steel grades SS304/SS316 (per ASTM A276) are listed. Confirm the material suitability for your environment.
Compressed air accelerates through a converging section, reaching maximum velocity at the throat, which causes a pressure drop below atmospheric pressure. This creates suction at the inlet. The air then expands through a diverging section, recovering pressure while maintaining the vacuum effect.
Inlet connection sizes range from 1/4 to 2 inches, with standard NPT or BSP threads. Choose the size that matches your system's piping and flow requirements.
