Is it possible to view the catalogs of each type of old AR series regulator (2 digits: AR□□, 4 digits: AR□□□□, and 3 digits: AR□□□) in order to replace them with current products?

Go to “Product Information” and then “Discontinued Product Information” on the SMC website. Select the AR series to view the catalogs of the discontinued products.
Be sure to check the model and dimensions of the old AR series products to be replaced (e.g., AR40, AR4000, or AR410) so an appropriate substitute can be ordered.
The discontinued AR series catalogs can be found here.
