Product Description

Dwyer MAFS-26 is a metal average flow probe for HVAC air flow measurement, featuring a 66 cm probe length and 1/4-20 threaded stud connection. Ideal for duct and plenum applications requiring accurate velocity averaging.

Frequently Asked Questions

What is the Dwyer MAFS-26 metal average flow probe used for?

The Dwyer MAFS-26 is used for HVAC air flow measurement in ducts and plenums. It provides accurate velocity averaging by measuring total and static pressure at multiple points, making it ideal for balancing and monitoring air handling systems in commercial and industrial buildings.

What are the specifications of the Dwyer MAFS-26?

The Dwyer MAFS-26 has a 66 cm probe length with a 1/4-20 threaded stud connection. It is made of aluminium AA6063, rated for clean air service up to 204 °C, with accuracy of ±2% FS from 400 to 9000 FPM. Minimum design flow is 2 m/s, maximum is 61 m/s.

Where to buy the Dwyer MAFS-26 in Singapore?

3G Electric supplies the Dwyer MAFS-26 to Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact our team for pricing and lead time on this model. We provide technical support for HVAC applications locally.

How to install the Dwyer MAFS-26 flow probe?

Install the Dwyer MAFS-26 from outside the duct using the 1/4-20 threaded stud. Ensure 5 duct diameters of straight run upstream for accurate readings. Connect the dual barbed fittings to 3/16" or 1/4" ID tubing for pressure sensing. Avoid obstructions near the probe.
