With a 14.75-inch insertion length, this probe samples air across multiple points in the duct cross-section and returns an averaged velocity signal, reducing the error introduced by non-uniform flow profiles. It handles velocity ranges from 200 to 6,000 FPM and is rated for air temperatures up to 250 degrees F. Licensed HVAC technicians and building commissioning professionals use this type of sensor for TAB work, system diagnostics, and demand-controlled ventilation applications.\u003c\/p\u003e\n\u003cp\u003eThe PAFS-1007 is suited for installation in rectangular or round commercial ductwork where a single-point measurement would produce unreliable readings. Typical applications include air handling units, supply and return duct mains, and outdoor air intake monitoring. The 14.75-inch insertion depth accommodates medium-width duct sections common in light commercial and larger residential systems. It is used in both new construction and retrofit scenarios where accurate airflow data is needed for system balancing or controls integration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAveraging multi-point probe design reduces velocity measurement error in turbulent or non-uniform airflow conditions\u003c\/li\u003e\n  \u003cli\u003eVelocity range of 200 to 6,000 FPM covers typical HVAC duct velocities\u003c\/li\u003e\n  \u003cli\u003e14.75-inch insertion length suits medium-depth duct installations\u003c\/li\u003e\n  \u003cli\u003eMaximum operating temperature of 250 degrees F supports standard HVAC air stream conditions\u003c\/li\u003e\n  \u003cli\u003eAir flow measuring probe type for direct duct insertion without external pitot traversal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style averaging flow sensor for use in commercial and residential HVAC ductwork and air handling systems where multi-point air velocity measurement is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or TAB (testing, adjusting, and balancing) professionals. The system fan and associated air handling equipment should be powered down before inserting or repositioning the probe. The probe must be inserted perpendicular to airflow and secured at the correct depth to ensure accurate averaging; consult the manufacturer installation sheet for mounting orientation. Follow local mechanical codes and ASHRAE guidelines for duct penetration sealing around the probe body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Air Flow Measuring Probe\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsertion Length\u003c\/strong\u003e: 14.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVelocity Range\u003c\/strong\u003e: 200 to 6,000 FPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DWYER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PAFS-1007\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DWYER","offers":[{"title":"Default Title","offer_id":51283892076850,"sku":"PAFS-1007","price":84.17,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279112.jpg?v=1781062515","url":"https:\/\/voomisupply.com\/products\/dwyer-pafs-1007-averaging-air-flow-sensor-14-75-in","provider":"Voomi Supply","version":"1.0","type":"link"}
