Measuring 20 inches high by 20 inches wide by 0.5 inches deep, this flat media pad delivers 833 CFM of rated airflow at a maximum face velocity of 300 feet per minute (FPM). It carries a 25% particle capture efficiency and 84% arrestance efficiency, making it effective at trapping larger airborne particles such as lint, dust fibers, and coarse debris. The pad features a dry tackifier treatment that helps retain captured particles within the media. HVAC technicians and service professionals install this pad as a primary or pre-filter stage in commercial and residential air handling units.\u003c\/p\u003e\u003cp\u003eThis media pad is suited for installation in HVAC air handling units, fan coil units, and equipment that accepts roll or cut-to-fit media. Its 20 by 20 inch cut dimensions and 0.5 inch depth make it a common fit for standard filter frames, media racks, and side-access air handlers where thin flat-pad filtration is specified. The pad is rated for continuous use up to 180 degrees F, allowing placement in applications with elevated operating temperatures. It is compatible with any unit that accepts media pad filtration in the corresponding cut size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMERV 7 rating with 25% particle capture efficiency and 84% arrestance efficiency\u003c\/li\u003e\n\u003cli\u003eRated airflow of 833 CFM at a maximum velocity of 300 FPM\u003c\/li\u003e\n\u003cli\u003ePolyester media construction with dry tackifier for improved particle retention\u003c\/li\u003e\n\u003cli\u003eMaximum operating temperature of 180 degrees F\u003c\/li\u003e\n\u003cli\u003eLow initial resistance of 0.09 inches water gauge (in. w.g.) for minimal static pressure drop\u003c\/li\u003e\n\u003cli\u003eUL Class 2 listed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a cut-to-fit or frame-mounted media pad replacement for any air handling unit or filter rack that accepts a 20 by 20 by 0.5 inch flat polyester media pad.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or qualified service professional. Always shut down the air handling unit and confirm power is off at the disconnect before removing or inserting filter media. Ensure the media pad is seated flush and fully within the filter frame or holding rack to prevent bypass airflow around the edges. Inspect the filter frame for damage or excessive dust buildup at each service interval.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParticle Capture Efficiency\u003c\/strong\u003e: 25%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArrestance Efficiency\u003c\/strong\u003e: 84%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated CFM\u003c\/strong\u003e: 833\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Face Velocity\u003c\/strong\u003e: 300 FPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial Resistance\u003c\/strong\u003e: 0.09 in. w.g.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal Resistance\u003c\/strong\u003e: 1.0 in. w.g.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedia Material\u003c\/strong\u003e: Polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedia Weight\u003c\/strong\u003e: 12.75 grams per square foot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 180 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeatures\u003c\/strong\u003e: Dry Tackifier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Met\u003c\/strong\u003e: UL Class 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRO-SOURCE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PRO11748\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51748838998322,"sku":"PRO11748","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e587e1bd58dc40654cdfc3c9b57fe86.jpg?v=1788899331","url":"https:\/\/voomisupply.com\/products\/pro-source-pro11748-polyester-air-filter-pad-20x20x0-5-merv-7","provider":"Voomi Supply","version":"1.0","type":"link"}
