When you're choosing between two filtration separation setups, the real decision is between two very different jobs. The TECHTONGDA 208-240V Industrial Cutting Fluid Oil-Water Separator Oil Skimmer 3-Phase is built to separate floating oil from cutting fluid so the coolant lasts longer and tools stay accurate. The PreAsion Industrial Liquid Filter Machine 1500W 220V 3-Phase Electroplating Nickel Platin is a vertical, large-capacity filter designed for electroplating solutions, chemical reagents, and other corrosive industrial liquids. They sit at almost the same price point, yet each is specialized for a separate workflow.
Quick Verdict
Choose the TECHTONGDA oil-water separator when your bottleneck is tramp oil floating in your cutting fluid tank. It skims that oil away, drains it for reuse, and includes a cleaning valve for removing sludge. Choose the PreAsion liquid filter machine when you need high-volume filtration of electroplating solutions or chemical baths with suspended solids and impurities. The machines don't overlap much; your application should decide.
Comparison Table
| Product | Listed Price | Job Focus | Best For | Power |
|---|---|---|---|---|
| TECHTONGDA Oil-Water Separator | $1,886.00 | Skims floating oil from cutting fluid | Machining coolant maintenance | 208-240V, 3-Phase |
| PreAsion Liquid Filter Machine | $1,922.90 | Filters electroplating and chemical liquids | Corrosive liquid filtration | 220V, 3-Phase, 1500W |
Where Each Product Wins
The TECHTONGDA oil-water separator wins for any shop that runs machine tools and wants to extend cutting fluid service life. Its job is to remove the floating oil that collects on the coolant surface, and the separated oil can be drained and reused. That directly addresses coolant contamination and helps protect both machining accuracy and employee health.
The PreAsion liquid filter machine wins when you're dealing with electroplating solutions, chemical reagents, or other liquids that need to be free of impurities. Its vertical, large-capacity design and large flow help process a big volume of industrial liquid quickly, making it a practical fit for electroplating lines where solution quality affects the finished surface.
Product Notes
208-240V Industrial Cutting Fluid Oil-Water Separator Oil Skimmer 3-Phase
This TECHTONGDA unit is a focused solution for cutting fluid maintenance. It recovers and reuses separated oil through a drain, which saves fluid and keeps the tank cleaner. The cleaning valve is there for sludge removal, so routine upkeep is part of the design. Its limitation is that it is not a general-purpose liquid filter; it is meant for separating floating oil from cutting fluid. If your process involves filtering electroplating or corrosive chemical solutions, this isn't the tool for that job. For a machining operation where coolant life and cleanliness are the priority, this separator targets the problem directly.
Industrial Liquid Filter Machine 1500W 220V 3-Phase Electroplating Nickel Platin
The PreAsion liquid filter machine is a vertical electroplating solution filter with a large-capacity design. It's made for filtering electroplating solutions, chemical reagents, and other industrial liquids, including corrosive ones. The large flow helps you get through substantial liquid volumes without slowing production, and removing suspended solids helps protect plating quality. That means it's aimed at continuous or high-use filtration in a plating shop, not at coolant tramp-oil removal. So if your issue is a layer of oil on cutting fluid, this filter isn't designed for that. But for keeping electroplating solution clean, it's a strong match.
Final Choice by Use Case
If you're maintaining machining coolant and want to separate and recover floating oil, go with the TECHTONGDA oil-water separator.
If you're filtering electroplating solutions or corrosive chemicals and need high throughput, go with the PreAsion liquid filter machine.
