Resideo AF11DS-1B Screen Kit

Resideo AF11DS-1B is a 20-micron replacement screen kit designed for use with compatible F76S inline water filters in HVAC and hydronic systems. This fine filtration screen is used to capture sediment, rust, and particulate debris in closed-loop or potable water applications, helping maintain proper flow and protect downstream components such as valves, pumps, and heat exchangers.

This filter screen kit is commonly used during routine maintenance or service replacement when existing screens become clogged or restrictive, leading to reduced flow or system performance issues. The 20-micron filtration rating provides fine particulate capture while maintaining adequate flow for residential and light commercial systems.

The AF11DS-1B is designed for use with 1/2" to 1.25" F76S filter housings and integrates into standard inline filtration assemblies. Proper sizing and compatibility with the existing filter body should be confirmed prior to installation to ensure correct fit and operation.
