Help: Special Considerations

Duplex
Duplex filters are used for systems that must run continuously. A duplex filter is just like a regular filter, but has two filters connected by a valve which selects which filter is active. This allows for the element that is idle to be changed without shutting down the operation.

Reverse Flow
For special systems where reverse flow is necessary, these filters incorporate a reverse flow bypass.

Bi-directional Flow
This is actually two reverse flow filters mounting in opposite directions, which traps the contamination between the two.
