Viton\u2122 fluoroelastomer performs at a wide range of temperatures, with oil and chemical resistance being unaffected by elevated temperatures. It also provides resistance to degradation by a wide variety of fluids and chemicals, including excellent resistance to oils, fuels, lubricants, and most mineral acids.<\/li>\n<li><strong>Aflas\u00ae<\/strong> &#8211; Aflas O-rings are suited for steam applications. TFE\/P is a copolymer of tetrafluoroethylene and propylene with a fluorine content of approximately 54%. A unique material due to its resistance to petroleum products, steam, and phosphate-esters, TFE\/P is ideal for heat transfer media, amines, acids and bases, as well as hot water and steam up to +170\u00b0C (+340\u00b0F). Service temperatures are (25\u00b0F) to +204\u00b0C (+400\u00b0F); The compression set resistance at high temperatures is inferior to standard fluorocarbons.<\/li>\n<li><strong>Kalrez\u00ae<\/strong> &#8211; DuPont\u2122 Kalrez\u00ae perfluoroelastomer (FFKM\/FFPM) parts resist over 1,800 different chemicals, while offering the high temperature stability of PTFE (327\u00b0C). They&#8217;re used in highly aggressive chemical processing, semiconductor wafer fabrication, pharmaceutical, oil and gas recovery, and aerospace applications.<\/li>\n<\/ul>\n<p><strong>Special Coatings<\/strong><br \/>\nIn addition to upgrading the seal elastomer, additional steps can be taken to protect your unit in demanding applications. pdblowers can coat the wetted components of your blower with Electrolysis Nickel, Armoloy\u00ae TDC, Gullon, or Gullite depending on your specific need. <a href=\"\/contact\/\">Contact us to speak with one of our professional application engineers.<\/a><\/p>\n\n","protected":false},"excerpt":{"rendered":"[message_string post=\"Roots_delay_typicallyNOTstockedmodel\"]\n[message_string post=\"Build_America_Buy_America\"]\n","protected":false},"featured_media":29442,"template":"","meta":{"_acf_changed":false},"product_cat":[107],"product_tag":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v22.3 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Whispair Gas Blower 412<\/title>\n<meta name=\"description\" content=\"pdblowers has a large selection of Whispair Gas Blowers including the popular 412 model.
