Common Questions

What is the difference between the C3510-8 and the 11AV?
The part number C3510-8 is functionally identical to the 11AV-3/4-400. It follows the same technical specifications, including the 3/4" NPT connection and 400 PSI rating.

Can this vent be used for steam applications?
While designed primarily as an air and gas vent, this unit is often utilized in steam systems specifically for air elimination needs to prevent cold spots and improve heat transfer.

Does this unit require regular gasket replacement?
No. The Armstrong 11AV series features a fully welded, permanently sealed stainless steel design with no gaskets, which minimizes maintenance requirements and prevents tampering.
