Although Filtra-Systems is known for designing and manufacturing great industrial filtration systems, we have also earned our reputation by providing excellent customer support to our clients around the world.
In addition to standard field service and replacement parts, we believe that educating our clients on product maintenance and best practices ensures that our clients are getting the most out of our systems for their business’ needs.
Minimizing potential issues for our customers is what we hope to achieve with this 8-step guide on how to properly replace cartridge filters.
Proper replacement of these cartridges reduces the risk of future problems occurring and maximizes floor cleanliness.
Your 8-step cartridge filter changing guide:
- Isolate the filter housing. Closing valves on both the inlet and the outlet will ensure that fluid is not introduced into the housing while it is open. Backpressure from the system may cause fluid to flow back into the housing, so it is important to close the outlet isolation valve as well.
- Open the vent valve. Venting the housing will allow excess pressure to bleed off, eliminating dangers when opening the housing. It will also prevent the housing from air locking when attempting to drain it. The vent should be plumbed to an upstream tank, to minimize operator exposure to process fluids.
- Open the drain valve. The housing must be drained before the cartridges can be accessed. Drain the fluid from the housing, and reintroduce it to the system upstream of the filter. A process should be developed that will ensure maximum plant cleanliness.
- Open and remove the lid. Remove the top plate so that the cartridges may be accessed.
- Remove cartridges, and discard.
- Install new cartridges. If Type 226 cartridges are used, remember to twist the cartridge into the base of the housing, so that they lock. Re-install the top plate, and tighten so that there can be no fluid bypass of the cartridges.
- Check the vessel gasket for defects, and make sure that it is in the proper position. Replace the lid.
- When refilling the housing, make sure that the drain is closed, and vent is open. Open the inlet, and leave the outlet closed. Venting the housing while refilling it will prevent air from being trapped in the housing. When the housing is full, and no air bleeds through the vent, close the vent and open the outlet. The housing is now back online.
