Filter kits and fans for Noren heat exchangers.


Filter Kits

Noren heat exchanger filter kits are designed to bolt directly to Noren heat exchangers and prevent dirt and dust from building up on the heat exchanger core.

Reusable aluminum filters are designed to be washed and reused.

Disposable poly filters are designed to be used for up to twelve months (depending on the amount of dirt and dust in the environment), then discarded and replaced.


Replacement heat exchanger fans can be ordered through our sales department. Standard fans are typically used in applications where there is a little to no chance of exposure to moisture or water. Universal fans are wet location fans that can be used in different environments. These typically have encapsulated motors. Non-standard fans are wash-down fans that are used in applications where the environment is damp.

Noren’s specially designed gaskets allow our heat exchangers to maintain an air tight seal, preventing contamination in the control panel and uphold various UL and NEMA integrity standards. We use high-quality neoprene seals to facilitate this process.
