Description
The Zilmet IK203 Magnetic Filter W/3/4″ NPT is a filtration part used in hydronic heating and cooling systems to capture ferrous debris and circulating contaminants from system water. It operates using an internal magnetic element combined with filtration to trap particles that can affect pumps, heat exchangers, and valves. Installed via 3/4″ NPT threaded connections, it is typically placed on the return line of boilers or HVAC hydronic loops. The unit supports system protection by improving water quality and maintaining efficient flow within closed-loop heating systems used in residential and commercial applications.
