The SMC 21-ARP40K-N04BG-Z is a copper, fluorine, and silicon-free precision regulator from the ARP series designed for low particle generation applications. Part number decoded: ARP = ARP precision regulator series, 40 = size 40, K = specific option, N04 = 1/2" NPT port, B = specific body option, G = gauge port, Z = low particle generation specification. The 21- prefix designates copper, fluorine, and silicon-free construction a stricter material standard than the standard 10-/11- clean room grades.
Why copper, fluorine, and silicon-free? In semiconductor fabrication, even trace amounts of copper, fluorine, or silicon in the compressed air system can contaminate wafers and damage process chemistry. The 21- series eliminates all materials containing these elements from the air path, including valve seats, seals, diaphragms, springs, and body coatings. This is critical for front-end semiconductor manufacturing, advanced packaging, and any process where metallic or halogen contamination from the pneumatic system would affect product quality.
The ARP40K-N04BG-Z provides precision pressure regulation with the highest material purity standard. For standard clean room regulators without Cu/F/Si-free requirements, the 10-IR series provides the base clean room option. The ARP series delivers tighter pressure regulation accuracy than standard regulators. The 1/2" NPT port handles high-flow applications. For smaller port precision regulators, the ARP series offers 1/4" and 3/8" options. RoHS compliant.
