Choosing a bag filter housing usually comes down to the size of the bag, the connection size, and the pressure your line runs at. The TECHTONGDA 1# Bag Industrial Filter addresses those decisions with a clear spec set: one #1 bag, 2-inch NPT ports, and a 120 PSI rating in a 304 stainless steel body.
Quick Verdict
At USD 528.24, this TECHTONGDA unit is a solid candidate for processes that need a single-bag filter with standard 2" NPT connections and stainless steel wetted parts. It keeps the housing simple with a stainless steel strainer basket and EPDM O-rings. The main trade-off is the pressure ceiling: if your system exceeds 120 PSI, you will need a different housing.
Who It Suits
This filter fits smaller industrial filtration jobs where the flow rate matches a #1 bag and where 2" NPT piping is already in place. It is also a reasonable option when 304 stainless steel is your material baseline for corrosion resistance. For higher flow rates or pressures above 120 PSI, you will likely outgrow this unit.
What Stands Out
The 304 stainless steel construction is the key feature, giving you a durable housing for water and many process fluids. The 2" NPT in/out connections make it easy to fit into standard industrial piping. The included strainer basket is a practical touch that protects the bag from coarse particles. The EPDM O-rings are a standard sealing material, and the 120 PSI rating combined with the single-bag design gives you a straightforward filtration package.
Trade-offs
The biggest limitation in the listed specification is the 120 PSI pressure rating. That is fine for many low-to-moderate pressure lines, but it rules out high-pressure applications. The single-bag configuration also caps your filtration area, so if your process demands high flow, you may need to install multiple units in parallel. Additionally, 304 stainless steel, while versatile, is not an all-purpose alloy; you need to match it to the fluids you are filtering.
Bottom Line
If your filtration task fits the #1 bag format and operates at or below 120 PSI with 2" NPT plumbing, the TECHTONGDA bag filter is a practical buy at USD 528.24. Its stainless steel build and strainer basket make it a straightforward housing for routine industrial filtration.
TECHTONGDA 1# Bag Industrial Filter 304 Stainless Steel 2" NPT In/Out 120 PSI
Listed at USD 528.24, this unit is a single-bag housing designed to accept a #1 bag and includes a stainless steel strainer basket. The 304 stainless steel body and EPDM O-rings are sized for piping that uses 2-inch NPT connections. One reason to choose it: the 120 PSI rating and stainless steel construction are clearly specified, so you can match it to your line. One limitation: it is a single-bag system, so if your process requires more filtration surface, a multi-bag unit would be a more practical choice.
