Choosing industrial filtration separation equipment starts with one question: do you need a consumable replacement element, a self-contained bag filter housing, or a powered liquid filter machine? The four options listed here span from a $5.50 filter sock to a $1,922.90 industrial plating filter, and the right pick depends on whether you already have a housing, want a stainless unit, or need a motorized filtration loop.
Quick take
For quick decisions: the Filpro DE5D4SS is the low-cost consumable for an existing 3-stage system; the TECHTONGDA 1# bag filter gives you a stainless housing for moderate flows; the Techtongda electric unit adds a self-priming pump for electroplating baths; and the PreAsion 1500W machine is the high-powered choice for larger chemical and plating volumes.

Product notes
Filpro DE5D4SS Industrial Liquid Filter Sock Bag
If you already operate a multi-stage filtration loop, this 5-micron sock bag is the consumable to watch. It is a made-in-USA filter used in food, pharmaceutical, microelectronics, chemical, and laboratory applications where fine particle removal is the point. It is also the lowest-priced item in this set, making it an easy line-item restock. The trade-off is that it is a replacement element, not a filter housing, so it only helps once you have the surrounding system that accepts a sock bag. Pick it when your existing filtration setup needs a 5-micron element and you want a no-fuss replacement.
Techtongda 220V Electric High Flow Industrial Liquid Filter
This vertical unit is aimed at electroplating and chemical liquid filtration, with a 6-core high-flow design and a self-priming pump. The 220V/750W motor is part of the package, so it can run as a complete powered solution rather than just a housing. That makes it a good fit if you want to circulate and clean plating solution in one unit. On the flip side, the motor and voltage need to align with your shop's setup: it runs on 220V and draws 750W. Choose it when you need a self-contained high-flow filter for a plating bath but don't need the larger motor in the next tier.
PreAsion Industrial Liquid Filter Machine
This is the highest-motor-power machine in the group, rated at 1500W on 220V three-phase power. Its design centers on a large-capacity, high-flow format for electroplating solutions and other corrosive industrial liquids. It is a full filter machine rather than a bag or sock, so it bundles the heavy lifting into one large unit. The main constraint is electrical: the 220V three-phase requirement belongs in a facility that already has that supply. If you need maximum listed wattage for plating filtration, this is the one.
TECHTONGDA 1# Bag Industrial Filter
This stainless steel bag filter brings a 304 housing, 2-inch NPT inlet/outlet, and a 120 PSI rating to the table. It is designed around a 1# bag filter format, so it occupies the middle ground between a replacement sock and a powered machine. If you want a durable stainless housing that uses replaceable filter bags, this unit is worth comparing to the electric filters. The limitation is scope: it is a single-bag filter with a 120 PSI rating, so its operating envelope is defined by that pressure limit rather than the high-flow circulation of the powered machines. Choose it when your priority is a stainless bag filter housing with NPT connections.
Final recommendation by use case
- Need a fine replacement element for an existing filtration loop? Go with the Filpro DE5D4SS sock bag.
- Want a stainless housing with replaceable bags for moderate flow? Pick the TECHTONGDA 1# Bag Industrial Filter.
- Need a powered electroplating filter with a self-priming pump? The Techtongda electric high-flow liquid filter is the match.
- Have a larger plating or chemical workload and three-phase power? The PreAsion 1500W industrial liquid filter machine is the top-spec choice in this group.
Match the filter to the flow and the power supply, and you will have a filtration separation setup that fits the price point.
