    Suction paper filter drier cores

    I recentley replaced a large 35HP compressor and also replaced the suciton drier cores. I gave my local dist the # on the can for both the suction and liquid cores- said the same for both. When i replaced the suction cores I found them to be pleated paper elements rather then the desicants like a liquid drier, thought to myself well thats what i was told, so i put the desicant liquid drier cores in the suction canister, is that ok and can I mess something up in doing so? I later was told that the pleateds should go in there from the same dist- go figure. Also was wondering if i need to change the suction core when changing the liquid line cores. Should they (suction) be changed also even if theres no obvious sign of restricion (psi/temp drop ect. )there. My gut says yes but $ a real issue for the customer (Like its not always but ya know).

    If it's a Sporlan RC-4864 core, it is the standard core suitable for both liquid and suction line applications.

    Suction line cores will break down over time and get into the system. The longest I will leave tem in for is around 30 days to clean up the system, then they are removed and pleated filters are put in.

    I've seen those pleated filters come apart and get into the system. I have found fibers from it in the TXV screen before. I leave em out.

    What is a felt? So there is a difference between a "suction core" and the pleated filter cores?

    A filter-drier core is the same for liquid or suction.

    Felt elements should be used in the suction line if you are not cleaning up the system.
