It is a silencer-type unit that handles both intake filtration and noise attenuation. The 16D filter element is pre-installed. Body dimensions are 6.75” outer diameter and 4.5” overall height — the same housing used across the S-16D series, with a 1” NPT inlet thread for the larger Castair cast iron pumps in 7.5–10 HP configurations.\u003c\/p\u003e\\n\\n\u003cp\u003ePer Castair's published pump cross-reference, the S-16D-100 is specified for their VA80, C1, C2, and C3 cast iron pump models. These are the mid-range pumps in Castair's industrial and commercial lineup. If you are replacing a worn filter on any of these pump models, or on any comparable 1” NPT inlet pump displacing up to 30 CFM, this is the correct part.\u003c\/p\u003e\\n\\n\u003ch3\u003eWhat the S-16D-100 Does\u003c\/h3\u003e\\n\u003cul\u003e\\n\u003cli\u003e\n\u003cstrong\u003eFiltration at 30 CFM:\u003c\/strong\u003e Removes airborne particulates before they reach the compression chamber.
