Product Description

Dwyer A-305SS is a stainless steel static pressure tap for HVAC and industrial airflow measurement applications. Features 304 stainless steel probe construction with 3/16" tubing ID connection, available in lengths of 101, 152, and 203 mm for ductwork integration.

Frequently Asked Questions

What is the Dwyer A-305SS static pressure tap used for?

The Dwyer A-305SS stainless steel static pressure tap measures static pressure in HVAC ductwork and industrial airflow systems. It connects to differential pressure switches and transmitters for applications such as monitoring pressure drop across air filters and cooling coils, ensuring accurate readings in ducts with air velocities up to 1500 PPM.

What are the specifications of the Dwyer A-305SS?

The Dwyer A-305SS features a 304 stainless steel probe, 303 stainless steel fitting, and 430 stainless steel flange. It has a 3/16" tubing ID connection and is available in lengths of 101 mm, 152 mm, and 203 mm. The probe includes a mounting flange with an integral rubber gasket and two screws for simplified duct installation.

Where to buy the Dwyer A-305SS in Singapore?

You can source the Dwyer A-305SS static pressure tap through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this Dwyer product, as we provide reliable sourcing for industrial measurement components.

How to install the Dwyer A-305SS static pressure tap?

Install the Dwyer A-305SS by mounting the flange on the duct wall using the two provided screws and integral rubber gasket. Connect 3/16" ID tubing to the barbed fitting. For accurate readings, position the probe away from duct walls to minimize turbulence effects, as recommended for permanent static pressure sensing installations.
