PreAsion #3 Bag Filter Housing 304 Stainless Steel
The #3 model uses 304 stainless steel with a 0.6 sq ft filtering area and a 20 µm filter bag. It includes a real-time pressure gauge to monitor internal pressure and facilitate timely relief of excess pressure. Best for mid-volume liquid filtration where real-time pressure visibility enhances process control. Suitable for filtration, purification, separation, and recovery in industrial settings. Caution: ensure compatible chemical compatibility with the filter bag material and gasket elastomer (EDPM).
2″ NPT Stainless Steel Bag Filter w/Mesh (TTeralmon)
This 2″ NPT model offers a large filtration area (0.46 m² / 4.95 ft²) and a high flow capability (30-40 t/h) with an inner wire DN50 connection. Best for heavy-duty filtration tasks requiring higher throughput and robust construction. It uses a quick-opening mechanism and a reinforced mesh basket for easy bag changes. Consider potential space requirements due to its tall profile, and ensure the bag size matches your process.
PreAsion #4 Bag Filter Housing 304 Stainless Steel
Provided with a pressure gauge for real-time monitoring, this model emphasizes energy savings through reusable filter bags and quick bag changes. It is suitable for water treatment and broader applications including printing inks and beverages. Best for operations prioritizing low operating costs and straightforward maintenance. Limitation: filter bag selection should match the liquid chemistry to prevent bag wear or bag degradation over time.
#2 Bag Filter Housing, 2″ NPT Heavy Duty 304 SS
This heavy-duty housing features a movable foot design and easy cleaning with smooth surfaces from sandblasting and polishing. It’s well-suited for facilities needing adjustable height and reliable filtration at higher pressures. Best for adaptable installation in spaces where height adjustments and easy cleaning matter. Caution: confirm available space for its full height and the required inlet/outlet alignment.
2″ Npt Bag Filter Housing, 304 Stainless Steel (#2 Mesh)
Equipped with a 2 mm wall thickness, this model offers a durable build and a 4.95 ft² filtration area via a 7.1×31.9 inch bag. It uses a reinforced mesh basket to support the filter bag, improving impurity interception. Best for high-efficiency filtration in chemical, oil, or water treatment. Limitation: ensure compatibility of the filter bag material with aggressive chemicals in your process.
PRM #4 304 Stainless Steel Bag Filter Housing
PRM offers a dual-port outlet design and a 150 PSI rating with up to 40 GPM flow. Constructed from 304 stainless steel, this housing suits flexible filtration setups where both side and bottom outlets are advantageous. Best for versatile filtration tasks in demanding environments. Caution: verify outlet plumbing compatibility with your existing piping layout to avoid flow restrictions.
1.5″ NPT TTeralmon Stainless Steel Bag Filter Housing
This model provides a 2.48 ft² filtration area with 1.5” NPT connections and adjustable feet for stable mounting. It also features a reinforced mesh basket and 304 stainless steel construction for long service life. Best for adjustable-height installations in compact or custom setups. Consider height constraints in facilities with limited space.
Buying Guide
What matters most when choosing a stainless steel bag filter housing?
- Filtration area: Larger areas reduce service intervals but increase footprint.
- Material and seals: 304 stainless steel is common; verify gasket material compatibility with liquids (water, oils, solvents).
- Pressure rating: Match your system’s operating pressure to prevent leaks and bag rupture.
- Bag compatibility: Ensure the bag size and mesh rating align with desired filtration fineness.
- Accessibility: Quick-opening mechanisms and gauge visibility simplify maintenance.
How to compare models efficiently?
- Check bag size and dimension requirements against your piping and space.
- Evaluate whether dual outlets or adjustable feet are needed for your setup.
- Assess cleaning procedures and ease of bag replacement to minimize downtime.
Maintenance and safety considerations
- Regularly inspect gaskets and O-rings for signs of wear or chemical attack.
- Use compatible cleaning agents to extend bag life and prevent corrosion.
- Monitor pressure with gauges to avoid over-pressurization and potential leaks.
Common questions
- What is the typical filtration area for these housings? Filtration areas vary; examples include 0.25–0.46 m² (2.7–4.95 ft²) depending on model and bag size.
- Are these housings suitable for oils and beverages? Yes, many models are designed for water, beverages, inks, and oils, with appropriate bag materials.
- Do all housings support quick-bag changes? Several models include quick-opening mechanisms for faster maintenance.
- What inlet/outlet options exist? Inlets/outlets include FNPT or NPT connections, with some dual-port configurations.
- Is a real-time pressure gauge common? Several models feature a gauge to monitor internal pressure during operation.
- Is stainless steel corrosion a concern? 304 stainless steel provides good corrosion resistance in common industrial environments; verify with your specific chemical exposure.
