COOLANT FILTERS HAVE SEVERAL DIFFERENT ROLES IN A COOLANT FILTRATION SYSTEM

Coolant filters have many different titles in a coolant filtration system depending upon where they are positioned and what their primary objective is. The roles are usually referred to as:

1. Primary filter
2. Bypass filter
3. Sidearm filter
4. Polishing filter
5. Guard filter
6. Batch filter
7. Recovery filter
8. Secondary filter
9. Pre-filter

Each has a function which is important to the overall system. The selection process will consider the location in the system where the filter will perform. For example consider the difference between the Polishing filter and the Guard filter.

A polishing filter is a secondary filter selected to intercept material which may migrate through the primary cleaning device. It is positioned as a full flow or sidearm unit depending upon the systems needs. The filter is sized to intercept the finer material and enhance the overall clarity of the coolant.

A guard filter is also a secondary filter but it is selected to protect a component or operation from a surge of contaminants if something goes wrong with the primary filter. It is positioned just ahead of the area it is protecting and sized to handle the flow with relatively high contamination for the emergency period until the main filter’s problem has been resolved.

Harrigan Solutions understands the difference in the two functions and can provide the engineering and equipment for each need. They sell or rent new and used filters depending upon the customers economical goals. Harrigan solutions also offers service agreements for companies who want to outsource some of they indirect maintenance needs.
