This article explains what to look for when choosing a stainless steel bag filter and how to compare models based on practical filtering performance and lifecycle costs.
PreAsion #4 Bag Filter Housing
The PreAsion bag filter housing uses 304 stainless steel for solid-liquid separation. It is designed for pressure filtration with a 1″ FNPT inlet/outlet configuration. A pressure gauge enables real-time monitoring to prevent over-pressurization. The unit supports reusable filter bags, enabling repeated use and cost savings, and promises low pressure loss to reduce energy consumption. Suitable applications include water treatment, printing inks, petroleum, and beverages, where reliable filtration and easy maintenance are valued.
2″ NPT Bag Filter Housing with Mesh
This 304 stainless housing features a 2″ NPT inlet/outlet and a substantial filtration area (about 4.95 ft²) via a side inlet that minimizes turbulence. The included high-quality pressure gauge supports precise real-time monitoring within a 1.0 MPa range. A reinforced mesh basket holds the stainless steel filter bag, enabling effective debris removal and consistent filtrate quality across varied industrial applications, including chemical processing and beverage filtration.
2″ NPT Bag Filter Housing, 150 PSI
The LTIGOAW 2″ NPT stainless steel bag filter housing combines durability with a streamlined filtration path. The 304 stainless steel construction is finished with a mirror polish for corrosion resistance and easy cleaning. It supports a 4.95 ft² filtration area via a side inlet, supporting high-efficiency filtration and longer service life. The quick-opening mechanism, reinforced mesh basket, and accessible bag replacement simplify maintenance in continuous operation scenarios across industrial water and chemical streams.
2″ NPT Stainless Steel Bag Filter w/Mesh
The TTeralmon housing emphasizes a robust, multi-purpose design with a 2″ NPT inlet and outlet and a 150 PSI rating. The unit features a durable 304 stainless steel body, a reinforced mesh basket for the filter bag, and a side inlet configuration that promotes efficient flow with minimal turbulence. The design prioritizes easy operation and straightforward maintenance, suitable for high-flow filtration tasks across industrial processes requiring reliable water filtration and impurity removal.
PRM #2 Bag Filter Housing
The PRM #2 housing is built for heavy-duty filtration with 2″ NPT in/out and a reinforced mesh basket. It features a movable foot design for adjustable height and a quick-opening mechanism to facilitate rapid bag changes. The stainless steel bag filter is designed to intercept particles effectively and deliver clean filtrate across a range of industrial applications, including large-scale water purification and chemical processing. This model emphasizes reliable seal integrity and easy maintenance in demanding environments.
Buying Guide
When choosing a stainless steel bag filter, consider:
- Material and corrosion resistance: 304 stainless steel is common and suitable for many water and chemical applications; higher grades may be needed for harsher fluids.
- Pressure rating and flow capacity: match the unit to your system’s operating pressure and desired throughput; look for 150 PSI or higher where applicable.
- Filtration area and bag type: larger filter areas improve efficiency and allow longer cycles between bag changes; verify bag size compatibility (e.g., 4.95 ft² area is common in 2″ NPT housings).
- Inlet/outlet compatibility: ensure 2″ NPT or 1″ FNPT configurations align with your piping; side-in, bottom-out paths help manage flow and turbulence.
- Maintenance features: quick-opening mechanisms, reinforced mesh baskets, and real-time pressure monitoring reduce downtime and maintenance costs.
- Bag replacement and availability: confirm bag availability, cleaning feasibility, and whether the system supports reusable or disposable bags to fit your operating costs.
- Footprint and installation: check height adjustability and base design to fit existing space and mounting options in your plant.
In practice, selecting a model with real-time pressure monitoring, a durable reinforced bag basket, and straightforward bag replacement minimizes downtime and extends filter life. Consider your primary fluid characteristics, including particulates, viscosity, and chemical compatibility, to choose the most suitable stainless steel bag filter housing for ongoing operations.
