Product Description

The Dwyer PAFS-1004 is an average flow probe designed for fluid measurement in industrial piping systems. It features ABS/polycarbonate construction rated UL94-5V and connects via 6 mm ID tubing. Operating range spans 4 to 49°C, making it suitable for HVAC and process monitoring applications.

Frequently Asked Questions

What is the Dwyer PAFS-1004 average flow probe used for?

The Dwyer PAFS-1004 average flow probe measures differential pressure in HVAC and process monitoring systems. It detects total and static pressure in variable-air-volume terminal units and ductwork, helping engineers balance airflow and monitor ventilation performance in commercial and industrial buildings.

What are the specifications of the Dwyer PAFS-1004?

The Dwyer PAFS-1004 has an ABS/polycarbonate body rated UL94-5V, a 19.55 cm probe length, and connects via 6 mm ID, 10 mm OD tubing. It operates from 4 to 49°C and stores from -40 to +60°C. The integral bracket with foam gasket simplifies mounting on ductwork.

Where to buy the Dwyer PAFS-1004 in Singapore?

3G Electric supplies the Dwyer PAFS-1004 average flow probe to Singapore. We handle sourcing, logistics, customs clearance, and local delivery. Contact our team for pricing and lead time on this measurement device for HVAC and process applications.

How to install the Dwyer PAFS-1004 average flow probe?

Mount the Dwyer PAFS-1004 using its integral bracket and foam gasket to seal against the duct. Connect 6 mm ID tubing to the push-on ports: the 'H' port for total pressure and the 'L' port for static pressure. Ensure the probe is perpendicular to airflow for accurate differential pressure readings.
