Silencer sizing
Size F2A acoustic solutions adapted to your ductwork.
Define your attenuation targets across the required frequencies and obtain your results in just a few clicks.
Export your results along with specification text in .xls, .pdf, and .csv formats.
Variable airflow damper sizing
Size your dampers according to the airflow control range, the optimal pressure drop required for proper ductwork balancing, and the maximum permitted noise level within the space.
Export your results, including specification texts, in .xls, .pdf, and .csv formats.
Antivibration systems calculation
Select the F2A antivibration systems optimized for your air handling unit by simulating three possible configurations:
- identical loads on each support point
- different loads on each support point
- casings
Define your performance objectives and rotation speed, and obtain your results in just a few clicks.
