Dwyer PAFS-1007 Averaging Air Flow Sensor 14.75 in

Product Description

The DWYER PAFS-1007 is an averaging air flow sensor probe designed for measuring air velocity in HVAC ductwork and air handling systems. 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.

The 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.

Key Features

• Averaging multi-point probe design reduces velocity measurement error in turbulent or non-uniform airflow conditions
• Velocity range of 200 to 6,000 FPM covers typical HVAC duct velocities
• 14.75-inch insertion length suits medium-depth duct installations
• Maximum operating temperature of 250 degrees F supports standard HVAC air stream conditions
• Air flow measuring probe type for direct duct insertion without external pitot traversal

Compatibility

Designed 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.

Installation Notes

Installation 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.
