Choosing between a complete chemical filter machine and a standalone bag filter housing is one of the bigger decisions in filtration separation. The TECHTONGDA High-Flow Industrial Chemical Filter is a new $2,245 unit aimed at electroplating and chemical fluids, while the Filtra Systems FSC Bag Filter Housing is a used $550 304 stainless steel housing for water, coolant, and oil. A new machine offers high-flow chemical handling out of the box, while a housing gives you flexibility to run your own filtration loop. Your choice comes down to the fluid you need to clean, the power you have available, and how much you want to spend.
Quick verdict
If your filtration separation work involves electroplating or aggressive chemicals and you need high flow, the TECHTONGDA High-Flow Industrial Chemical Filter is the capable choice. If you are processing water, coolant, or oil and want to keep costs down, the Filtra Systems FSC Bag Filter Housing offers a durable stainless vessel at a far lower price. Neither option is inherently better; the best pick depends on your process.
At a glance
The table below lays out the key differences in price, condition, and intended use.
| Feature | TECHTONGDA High-Flow Chemical Filter | Filtra Systems FSC Bag Filter Housing |
|---|---|---|
| Price | USD 2,245.00 | USD 550.00 |
| Condition | New | Used |
| Target fluids | Electroplating solutions, chemical reagents, corrosive industrial fluids | Water, coolant, and oil |
| Design | Vertical liquid filter machine with high-flow design | Single bag housing with single basket / bag support basket |
Where each product wins
- TECHTONGDA High-Flow Chemical Filter wins for electroplating and chemical-heavy processes, where its high-flow, complete machine design and new condition make it a complete machine solution.
- Filtra Systems FSC Bag Filter Housing wins for general industrial liquid filtration that needs a dependable 304 stainless steel housing, especially when you already have the surrounding system and want to spend less.
Keep the price difference in mind: you are paying for a complete machine with TECHTONGDA and for a durable but used housing with Filtra Systems.
Product notes
TECHTONGDA High-Flow Industrial Chemical Filter for Injection Molding Nickel Plating 220V
This unit sits at the higher price of the pairing, but it arrives new and is engineered for the electroplating industry. Its vertical liquid filter machine design targets high-flow filtration of electroplating solutions, chemical reagents, and other corrosive industrial fluids. If you run injection molding, nickel plating, or similar aggressive processes, this machine is built to remove suspended solids at volume. The 220V power requirement is worth planning for, because not every shop has that outlet available. If your process demands high throughput and heavy-duty chemical capability, the TECHTONGDA gives you a purpose-built complete machine rather than a separate housing that you would have to build into a system. Its high-flow design and compatibility with corrosive fluids are the main reasons to choose it over the Filtra Systems housing.
Filtra Systems FSC Bag Filter Housing 304 Stainless Steel 150 PSI Industrial
This is the lower-priced of the two and comes in used condition. The 304 stainless steel construction and 150 PSI rating make it a durable choice for process liquids such as water, coolant, and oil, and the single basket / bag support basket design keeps replacement simple. You are getting a housing, not a complete pumped system, so you will need to supply your own pump and piping. The used condition is worth factoring into your purchase decision, and the single-bag format gives you one filtration point at a time. For operations that already have a filtration loop and simply need a reliable, lower-cost stainless vessel, the Filtra Systems housing is a straightforward buy. It handles moderate industrial duty without the high price tag of the TECHTONGDA machine.
Final choice by use case
- Choose the TECHTONGDA High-Flow Chemical Filter if your priority is high-volume filtration of electroplating, chemical reagents, or corrosive fluids and you have 220V power available.
- Choose the Filtra Systems FSC Bag Filter Housing if you are filtering water, coolant, or oil and prefer a lower-cost, used stainless housing with a single-bag design.
