Airflow Instruments Positive and Negative Duct Accreditation System PAN341


The Airflow™ Instruments Positive and Negative Duct Accreditation (PANDA) System PAN341 Series provides contractors, commissioning engineers, and research and development technicians with the best in class choice of test equipment to quantify air leakage in ductwork and other areas as well as the ability to measure the performance of ducted systems.

Product Details

The PANDA provides a fast, accurate, automated solution and helps to ensure compliance with European standards like EN12237, EN1507, EN13779, EUROVENT 2/2 standards and with American standards like SMACNA, enhancing energy savings in buildings.

Note: PAN341 is not available for sale in the U.S.
