Delivering Quality Filtration Since 1946
Q: How do I know when to change a filter?
A: There are two ways: differential pressure gauges tell you how much harder your pump has to work to push through the filter. At some point (10 psi to 15 psi), most of the filter is used up. The other way is to monitor your flow output and when it reaches a point below your requirements, change the filter.
Q: When do I use a filter bag vs. a filter cartridge?
A: Filter bags typically offer more flow rates, but less dirt holding capacity than cartridges. Cartridges offer more material options as well. If you have a fairly clean stream and just need to get out occasional particles, a bag filter might work well. If you need more flexibility and more precise filtration, go with cartridges.
Q: How do I know what size filter I need?
A: Typically, this decision is based on flow rate. Factoring percentage of particulate (% of solids) can also factor into sizing. We base flow on 10” equivalents for standard filters, which we usually don’t exceed 5 GPM per 10”. Filter bags, standard #2 size can flow up to 150 GPM depending on micron rating and efficiency
Q: Why should I filter my lubrication oil?
A: Filtration of lube oil, especially with a continuous kidney loop filter, benefits lubrication oil applications by greatly reducing metal to metal wear and extending the life of machinery and the oil that serves it.
