Frequently Asked Questions

What is the Dwyer AAFS air flow controller used for?

The Dwyer AAFS is used to detect and control air velocity in horizontal duct mounting for HVAC and industrial ventilation systems. It features a stainless steel paddle and ABS housing, with a setpoint adjustable via internal screw, making it suitable for monitoring airflow in clean air and compatible gas services.

What are the specifications of the Dwyer AAFS air flow controller?

The Dwyer AAFS measures airflow from 1 to 9.2 m/sec, has an IP65 rated ABS housing, a stainless steel paddle, flange connection, and SPDT switch rated 15(8) A @ 250 VAC. Ambient temperature range is -40 to +85 °C, process temperature -10 to +85 °C, and humidity 10 to 90% non-condensing.

Where to buy the Dwyer AAFS air flow controller in Singapore?

You can source the Dwyer AAFS air flow controller through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this model (SKU 3G-CBM-02191) and other Dwyer instrumentation products.

How to install the Dwyer AAFS air flow controller?
