Product Description

The Dwyer MAFS-40 is an average flow rate metal probe designed for HVAC ductwork applications, featuring a 101.6 cm probe length with uniformly distributed static and total pressure measurement points for accurate airflow quantification in duct systems.

Frequently Asked Questions

What is the Dwyer MAFS-40 used for?

The Dwyer MAFS-40 average flow rate metal probe is used in HVAC ductwork to measure airflow by sensing static and total pressure. It is ideal for use with Dwyer air velocity sensors, transmitters, and switches in commercial and industrial ventilation systems.

What are the specifications of the Dwyer MAFS-40?

The Dwyer MAFS-40 has a 101.6 cm probe length, is made of aluminium AA6063, and is rated for clean air service. Accuracy is ±2% FS from 400 to 9000 FPM (45.7 m/s). Maximum temperature is 204 °C. Minimum design flow is 2 m/s; maximum is 61 m/s.

Where to buy the Dwyer MAFS-40 in Singapore?

3G Electric supplies the Dwyer MAFS-40 to Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this model (SKU 3G-CBM-02222).

How to install the Dwyer MAFS-40?

The Dwyer MAFS-40 can be installed entirely from outside the duct, making setup quick. Ensure 5 duct diameters of straight run upstream. Connect the dual barbed fittings to 3/16" or 1/4" ID tubing. Follow Dwyer's guidelines for proper orientation of static and total pressure ports.
