In practical terms, a lower PPI ceramic foam filter has larger pores and usually provides higher metal-flow capacity with lower blockage risk, while a higher PPI filter has smaller pores and can capture finer inclusions but creates greater resistance to molten-metal flow. There is therefore no universally &#8220;best&#8221; PPI. We normally select the coarsest pore structure that can consistently achieve the required casting cleanliness, then confirm that choice through flow-capacity calculations and controlled foundry trials. Typical commercial grades include 10, 20, 30, 40, 50 and 60 PPI, although available specifications vary by ceramic composition and manufacturer. For many applications, roughly 10 to 30 PPI is associated with iron and steel filtration, while aluminum-alloy filtration commonly uses approximately 20 to 60 PPI. These ranges are starting points rather than fixed engineering rules.<\/p>\n<p>At AdTech, we regard PPI selection as a filtration-system decision rather than simply a filter purchasing decision. PPI tells us the nominal number of pores per linear inch, but it does not independently define filtration efficiency, permeability, pore-window size, thermal-shock resistance or metal capacity. Two filters marked &#8220;30 PPI&#8221; can behave differently because their ceramic chemistry, foam morphology, coating thickness, open porosity, pore-window distribution and manufacturing consistency differ. Engineers and buyers should therefore evaluate PPI together with filter material, filter area, thickness, casting process and measurable quality parameters.<\/p>\n<figure id=\"attachment_3639\" aria-describedby=\"caption-attachment-3639\" style=\"width: 1300px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-3639\" src=\"https:\/\/www.c-adtech.com\/wp-content\/uploads\/2026\/09\/7602_vN9YzPA4.webp\" alt=\"\u30a2\u30eb\u30df\u30cb\u30a6\u30e0\u92f3\u9020\u7528\u30a2\u30c9\u30c6\u30c3\u30af\u30fb\u30a2\u30eb\u30df\u30ca\u30bb\u30e9\u30df\u30c3\u30af\u30d5\u30a9\u30fc\u30e0\u30d5\u30a3\u30eb\u30bf\u30fc\" width=\"1300\" height=\"1210\" srcset=\"https:\/\/www.c-adtech.com\/wp-content\/uploads\/2026\/09\/7602_vN9YzPA4.webp 1300w, https:\/\/www.c-adtech.com\/wp-content\/uploads\/2026\/09\/7602_vN9YzPA4-300x279.webp 300w, https:\/\/www.c-adtech.com\/wp-content\/uploads\/2026\/09\/7602_vN9YzPA4-1024x953.webp 1024w, https:\/\/www.c-adtech.com\/wp-content\/uploads\/2026\/09\/7602_vN9YzPA4-768x715.webp 768w, https:\/\/www.c-adtech.com\/wp-content\/uploads\/2026\/09\/7602_vN9YzPA4-13x12.webp 13w\" sizes=\"(max-width: 1300px) 100vw, 1300px\" \/><figcaption id=\"caption-attachment-3639\" class=\"wp-caption-text\"><a href=\"https:\/\/www.c-adtech.com\/ja\/%e8%a3%bd%e5%93%81\/ceramic-foam-filter\/\">\u30a2\u30eb\u30df\u30cb\u30a6\u30e0\u92f3\u9020\u7528\u30a2\u30c9\u30c6\u30c3\u30af\u30fb\u30a2\u30eb\u30df\u30ca\u30bb\u30e9\u30df\u30c3\u30af\u30d5\u30a9\u30fc\u30e0\u30d5\u30a3\u30eb\u30bf\u30fc<\/a><\/figcaption><\/figure>\n<h2>\u30bb\u30e9\u30df\u30c3\u30af\u30d5\u30a9\u30fc\u30e0\u30d5\u30a3\u30eb\u30bf\u30fc\u306b\u8a18\u8f09\u3055\u308c\u3066\u3044\u308b\u300cPPI\u300d\u3068\u306f\u3069\u3046\u3044\u3046\u610f\u5473\u3067\u3059\u304b\uff1f<\/h2>\n<p>PPI means &#8220;pores per inch.&#8221; It is a commonly used description of the cellular structure of reticulated ceramic foam.<\/p>\n<p>10 PPI\u306e\u30d5\u30a9\u30fc\u30e0\u306f\u3001\u6bd4\u8f03\u7684\u7c97\u3044\u7d30\u80de\u69cb\u9020\u3092\u6709\u3057\u3066\u3044\u307e\u3059\u3002A <a href=\"https:\/\/www.c-adtech.com\/ja\/30-ppi-ceramic-foam-filter\/\">30 PPI<\/a> \u3053\u306e\u88fd\u54c1\u306f\u3088\u308a\u5fae\u7d30\u306a\u69cb\u9020\u3092\u6709\u3057\u3066\u304a\u308a\u300150\u307e\u305f\u306f60 PPI\u306f\u3001\u3055\u3089\u306b\u5fae\u7d30\u306a\u516c\u79f0\u7d30\u5b54\u7b49\u7d1a\u3092\u8868\u3057\u3066\u3044\u307e\u3059\u3002PPI\u3092\u9ad8\u304f\u3059\u308b\u3068\u3001\u4e00\u822c\u7684\u306b\u7279\u5fb4\u7684\u306a\u7d30\u5b54\u7a93\u306e\u5bf8\u6cd5\u304c\u5c0f\u3055\u304f\u306a\u308a\u3001\u5305\u6709\u7269\u3068\u76f8\u4e92\u4f5c\u7528\u3067\u304d\u308b\u5185\u90e8\u8868\u9762\u7a4d\u304c\u5897\u52a0\u3057\u307e\u3059\u3002.<\/p>\n<p>\u3053\u308c\u306f\u5358\u7d14\u305d\u3046\u306b\u805e\u3053\u3048\u307e\u3059\u304c\u3001PPI\u3092\u6b63\u78ba\u306a\u3075\u308b\u3044\u306e\u76ee\u958b\u304d\u3068\u3057\u3066\u89e3\u91c8\u3059\u3079\u304d\u3067\u306f\u3042\u308a\u307e\u305b\u3093\u3002.<\/p>\n<p>\u30bb\u30e9\u30df\u30c3\u30af\u30d5\u30a9\u30fc\u30e0\u30d5\u30a3\u30eb\u30bf\u30fc\u306f\u3001\u5747\u4e00\u306a\u6b63\u65b9\u5f62\u306e\u958b\u53e3\u90e8\u3092\u6301\u3064\u7e54\u7269\u30b9\u30af\u30ea\u30fc\u30f3\u3068\u306f\u7570\u306a\u308a\u3001\u4e09\u6b21\u5143\u306e\u7db2\u76ee\u69cb\u9020\u3068\u306a\u3063\u3066\u3044\u307e\u3059\u3002\u305d\u306e\u7d30\u5b54\u3084\u958b\u53e3\u90e8\u306e\u5f62\u72b6\u3084\u76f4\u5f84\u306f\u3055\u307e\u3056\u307e\u3067\u3059\u3002\u6eb6\u878d\u91d1\u5c5e\u306f\u3001\u4e92\u3044\u306b\u9023\u306a\u308a\u304f\u306d\u304f\u306d\u3068\u3057\u305f\u901a\u8def\u3092\u901a\u3063\u3066\u6d41\u308c\u308b\u305f\u3081\u3001\u308d\u904e\u306f\u5358\u7d14\u306a\u6a5f\u68b0\u7684\u3075\u308b\u3044\u5206\u3051\u3067\u306f\u306a\u304f\u3001\u3044\u304f\u3064\u304b\u306e\u30e1\u30ab\u30cb\u30ba\u30e0\u306b\u3088\u3063\u3066\u884c\u308f\u308c\u307e\u3059\u3002.<\/p>\n<p>\u3053\u306e\u9055\u3044\u306f\u3001\u30b5\u30d7\u30e9\u30a4\u30e4\u30fc\u3092\u6bd4\u8f03\u3059\u308b\u969b\u306b\u91cd\u8981\u306b\u306a\u308a\u307e\u3059\u3002.<\/p>\n<p>A purchasing specification stating only &#8220;30 PPI ceramic foam filter&#8221; leaves several important properties undefined.
