Particulate in a chilled or process water loop wears pump seals, fouls heat exchanger surfaces, and plugs small passages in molds, dies and coolant circuits faster than most operators expect. Inline filtration sits in the loop ahead of the equipment it's protecting and removes that particulate before it can do damage - it's a small, inexpensive component that prevents a much more expensive repair further down the line.
Advantage offers two filter types: disposable bag filters, sized BF-25 through BF-600, and permanent media filters, sized PM-24 through PM-36, that use reusable, cleanable media instead of a disposable bag. Both are complete filter housings and elements, not accessories to something else - each ships ready to plumb into the loop's return line.
Which Type Is Right?
Advantage bag filters are the simpler, lower first-cost option and the default choice for most loops - the housing is inexpensive and a spent bag is pulled and replaced in minutes. Permanent media filters cost more up front but are worth it where filter changes are frequent or where disposing of used bags is a hassle the plant would rather not deal with on a recurring basis. Neither type substitutes for the other; the choice comes down to particulate load and how the plant prefers to handle service.
Replacement filter media and cartridges for either type are available on request - tell us your existing filter model or your flow rate and particulate concerns and we'll match a filter and confirm consumables.
What Sizing A Filter Comes Down To
Flow
GPM, Not Pipe Size
Matched To The Loop
A filter housing has to be sized to the loop's actual flow rate, not just the pipe diameter it's plumbed into - an undersized housing raises pressure drop across the system, while an oversized one adds cost with no benefit.
Load
What's In The Fluid
Particulate Source
Scale, machining fines and biological growth all load a filter differently. Knowing what's actually generating particulate in the loop points toward the right micron rating and service interval, not just a model number off a chart.
Service
Bag Or Media
Ongoing Cost Trade-Off
A disposable bag is cheaper per housing but recurring; a permanent media element costs more up front and less over time. High-particulate loops with frequent changes usually favor permanent media once the bag consumable cost adds up.
Placement
Protects What's Downstream
Ahead Of Pumps & HX
Filtration is only doing its job when it sits upstream of the equipment it's protecting. Placed after the pump or heat exchanger, it stops protecting anything - filter position in the loop matters as much as the model selected.
Choosing A Filter Type
Start with the loop's flow rate and what's generating particulate. From there it's a service-cost decision: a lower-cost bag housing with recurring bag purchases, or a higher-cost permanent media housing with a lower, less frequent ongoing spend. Loops feeding sensitive plate-and-frame or brazed-plate heat exchangers are worth filtering more conservatively than a loop feeding only a shell-and-tube unit.
If you're replacing an existing filter, the current model number is usually the fastest path to a match - send it along with your flow rate and we'll confirm fit before quoting.
