Product Description

The Dwyer MAFS-34 is an average flow metal probe for HVAC air velocity measurement, featuring an 81 cm probe length and 1/4-20 threaded stud connection. It integrates into duct systems for airflow assessment.

Frequently Asked Questions

What is the Dwyer MAFS-34 average flow metal probe used for?

The Dwyer MAFS-34 is used for HVAC air velocity measurement in duct systems. It integrates into round or rectangular ducts to deliver accurate airflow assessment using evenly spaced total and static pressure sensing points, making it ideal for use with Dwyer air velocity instruments, transmitters, and switches.

What are the specifications of the Dwyer MAFS-34?

The Dwyer MAFS-34 has an 86 cm probe length and a 1/4-20 threaded stud connection. It is made of aluminium AA6063, rated for clean air service, with a maximum temperature of 204 °C and a design flow range of 2 m/s to 61 m/s. Accuracy is ±2% FS from 400 to 9000 FPM.

Where to buy the Dwyer MAFS-34 in Singapore?

How to install the Dwyer MAFS-34 in a duct system?

The Dwyer MAFS-34 can be installed entirely from outside the duct, making setup quick. Insert the probe into a round or rectangular duct, ensuring at least five duct diameters of straight pipe upstream. Secure using the 1/4-20 threaded stud and connect the dual barbed fittings to 3/16" or 1/4" ID tubing.
