Quick Verdict
When you need a bag filter housing for industrial liquid filtration, the decision comes down to condition and operating pressure. Bag filter housings like these sit between the pump and the process vessel, so the working pressure has to match what the rest of the line can deliver. The Filtra Systems FSC is a used housing with a single basket/bag support basket. The TECHTONGDA 1# Bag is a new unit with a stainless steel strainer basket. Their listed prices sit close together, so the practical question is whether you want the higher pressure ceiling of the used Filtra Systems or the new-condition TECHTONGDA. For shops that already run bag-style filtration, the choice is mostly about the trade-offs each unit brings.

Where Each Housing Wins
Filtra Systems FSC wins for buyers who need the higher working pressure and are comfortable with a used vessel. The nameplate details on temperature and differential pressure make it easier to plan where the housing can run in a process line.
TECHTONGDA 1# Bag wins for shoppers who want a new unit at the lower listed price. The complete-unit presentation and the clearly stated port size remove some of the guesswork when planning a hookup.
Filtra Systems FSC Bag Filter Housing 304 Stainless Steel 150 PSI Industrial
This is the higher-pressure option in this pairing. The nameplate lists a maximum working temperature of 210°F and a maximum differential pressure of 35 PSI, which gives a clear operating envelope for applications filtering water, coolant, and oil. It uses the basket support layout typical of bag filter housings, so it will feel familiar to anyone who has worked with this style of vessel. The unit is listed as used, so the practical decision comes down to accepting a pre-owned housing in exchange for the higher pressure capability. For process lines that need that extra pressure headroom, this housing fits the requirement without straying from standard bag filter practice.
TECHTONGDA 1# Bag Industrial Filter 304 Stainless Steel 2" NPT In/Out 120 PSI
The TECHTONGDA unit is the new-condition alternative. It is offered as a complete bag filter housing unit, with the 2" NPT in/out connections stated in the title so the port size is clear for piping plans. Its pressure rating covers typical industrial filtration needs, and the EDPM O-rings support standard liquid-filtration service. The pressure ceiling is more conservative than the Filtra Systems housing, so it suits lines that stay within the stated limit. If you are starting a new installation and want the simplicity of a fresh unit rather than a used housing, the TECHTONGDA avoids the condition question entirely while coming in at the lower listed price.
Final Choice by Use Case
- Higher pressure process lines: Filtra Systems FSC. If the line regularly runs above the new unit's rating, the used Filtra Systems housing provides the headroom.
- New equipment preference: TECHTONGDA 1# Bag. A fresh unit avoids the condition variable entirely.
- Budget-conscious install: TECHTONGDA, with the lower listed price of the two.
- Water, coolant, and oil filtration with a pre-owned housing: Filtra Systems FSC, matching those applications with a higher pressure envelope.
