Schroeder (**) Media Grade S1 -3 S3 -10 S7 S10 -25	Recommended Pall (**) Media Grade KP KS	Original housings often use a stack of two or three A, J, or K elements. Replacing these with a single Pall filter element is recommended. Pall filter elements can also be stacked using existing connectors, or for the 9735 and 9700 series, Pall connector p/n HBS630-1D5 can be used. Schroeder designates Fluorocarbon seals with a ‘V’ (Viton). Change the ending ‘H’ in Pall p/n to ‘Z’ for this option.
