FA一PF初效过滤器在滤材打褶前，先将一层镀锌铁网贴合在滤材的出风面上，这层铁网不但能保护滤材不被吹破，亦能防止滤材因风压力而造成变形，故能确保所有滤材表面皆能被充分利用。用特殊的***手法对滤材纤维进行处理，使其形成渐层式的结构，如此过滤器便有较高的捕尘量、较长使用寿命的特性。过滤器的外框是以坚固的防水板组成，用来固定已折叠完成的滤材。外框上对角线的设计能提供大过滤面积，并使内部滤材紧密的粘附在外框上。过滤器的四周皆以特殊的***粘合胶水与外框粘合，能防止空气泄漏或因风阻压力造成破损的情况发生。特性：滤网分为深度1''、2''、4''三种尺寸，其过滤面积是一般平面滤网的五倍，它比一班玻璃纤维过滤器或人造纤维过滤器具有较长的使用寿命以及较高的过滤效率。可以直接使用或是当作初级过滤器，用来保护空调系统中后段的中、***率过滤器。将纤维用特殊的轧针手法处理，使其形成渐层式样的结构，如此过滤器便具有低压损、高捕尘量、长使用寿命的特性。用途：一般空调的粗过滤系统，可延长袋式及HFPA过滤器的使用寿命工厂废气、加工集尘的粗过滤网。产品规格：标准尺寸实际尺寸风量（CFM）滤材面积(SQFT)SIZEHWDMEDIUMHIGHSTDCAPHIGHTCAP8X16X173/453/43/43254501.62.410X10X193/493/43/42503501.31.710X20X191/2191/23/45257002.53.210X24X193/8233/83/46258253.03.910X25X193/4243/43/46508203.14.112X12X1113/4113/43/43758501.82.312X16X1113/4153/43/45005002.43.212X20X1113/4193/43/46256503.04.012X24X1113/8233/83/47508253.64.812X25X1113/4243/43/477510003.75.014X20X1131/2191/23/472510253.54.714X24X1133/8233/83/48759754.25.714X25X1131/2241/23/490011504.45.915X20X1141/2191/23/477512003.75.015X25X1141/2241/23/497510504.76.216X16X1153/4153/43/465013003.24.316X20X1151/2191/23/48258754.05.216X24X1153/4232/83/4100011004.86.316X25X1151/2241/23/4105013255.05.618X18X1173/4173/43/485014004.15.518X20X1173/4193/43/492511254.56.018X22X1173/4213/43/4102512505.06.718X24X1173/8233/83/4112513755.47.218X25X1171/2241/23/4117515005.67.520X20X1191/2191/23/4105015505.06.720X24X1193/8233/83/4125014006.08.120X25X1191/2241/23/4130016506.28.422X22X1213/4213/43/4125017506.18.122X24X1233/8233/83/4150016757.29.625X25X1243/4243/43/4162520007.810.310X10X293/493/413/42503502.13.210X20X291/2191/213/42505254.16.212X20X2113/4193/413/46258255.27.812X24X2113/8233/813/475010006.29.314X20X2131/2191/213/47259756.28.814X25X2131/2241/213/490012007.811.015X20X2141/2191/213/477510256.79.816X16X2153/4153/413/46508755.58.416X20X2151/2191/213/482511006.710.416X24X2153/8233/813/4100013258.112.416X25X2151/2241/213/4105014008.412.918X22X2173/4213/413/4102513758.613.218X24X2173/8233/813/4112515009.314.318X25X2173/4243/413/4117515009.714.920X20X2191/2191/213/4105014008.812.920X24X2193/8233/813/41250165010.615.520X25X2191/2241/213/41300175011.016.224X24X2233/8233/813/41500200012.418.625X25X2243/4243/413/41625215013.620.112X24X4113/8233/835/81000125011.515.316X20X4153/8193/835/81100140012.817.516X25X4153/8243/835/81400175016.021.318X24X4173/8233/835/81500187517.923.020X20X4193/8193/835/81400175016.021.320X24X4193/8233/835/81657210019.225.520X25X4193/8243/835/81750220019.925.520X25X4193/824/3835/81750220019.926.624X24X4233/8233/835/82000250023.030.625X29X4243/8283/835/82625313529.338.628X30X4273/8293/835/82900365034.344.7)
