{"product_id":"castair-ek602vb","title":"Castair EK602VB","description":"\u003cp\u003eThe Castair EK602VB is the replacement filter element for the Castair FS114 and FS112 particulate filter bodies — the 1-1\/4\" and 1-1\/2\" NPT standard-size inline air filters in Castair's FRL (Filters, Regulators, Lubricators) lineup. When the filter element inside your FS114 or FS112 filter bowl becomes loaded with particulate — metal fines, pipe scale, rust particles, compressor wear debris — the element needs to be replaced to restore full flow and filtration effectiveness. The EK602VB is the correct OEM element for these bodies; using a non-matching element risks either bypassing filtration (if the element doesn't seal the bowl correctly) or restricting flow more than necessary.\u003c\/p\u003e\n\n\u003ch2\u003eCompatible Filter Bodies\u003c\/h2\u003e\n\u003cp\u003eThe EK602VB fits these specific Castair filter housings from the 7000 series:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFS114 (1-1\/4\" NPT):\u003c\/strong\u003e 250 PSI max, 390 CFM, 16 oz bowl capacity — the 1-1\/4\" standard particulate filter in Castair's FRL catalog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFS112 (1-1\/2\" NPT):\u003c\/strong\u003e 250 PSI max, 390 CFM, 16 oz bowl capacity — the 1-1\/2\" standard particulate filter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDo not use the EK602VB in other Castair filter bodies. Castair's filter element catalog lists specific elements for each filter body size — using the wrong element in a filter housing can result in bypass (the element doesn't seal, so unfiltered air passes around it) or an element that won't seat correctly in the bowl.\u003c\/p\u003e\n\n\u003ch2\u003eFilter Performance Context\u003c\/h2\u003e\n\u003cp\u003eThe FS114 and FS112 bodies are 5-micron particulate filters.

A clogged element increases pressure drop across the filter, which means lower working pressure at the point of use even if your compressor is delivering full tank pressure. Replace the EK602VB element when you see increased pressure drop (check pressure before and after the filter with gauges) or on a regular maintenance schedule based on your system's particulate load.\u003c\/p\u003e\n\n\u003ch3\u003eCastair Filter Element Cross-Reference\u003c\/h3\u003e\n\u003cp\u003eFor reference, here are the correct elements for other Castair filter bodies — confirm you have the right element for your housing:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eC-FM14 (1\/4\" mini):\u003c\/strong\u003e Use C-F2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC-CF12 and C-CF34 (coalescing, 1\/2\" and 3\/4\"):\u003c\/strong\u003e Use C-F7 (7000 series) or C-F7607\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC-CF10 (coalescing, 1\"):\u003c\/strong\u003e Use C-F9 or C-FM907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFS114 and FS112 (particulate, 1-1\/4\" and 1-1\/2\"):\u003c\/strong\u003e Use EK602VB (this element)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOne (1) EK602VB replacement filter element\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eNote: Exact filtration rating, element dimensions, and change interval recommendations are not published in Castair's public catalog for this specific element.
