Corrosion Resistant Liquid Filtration
PP, GFPP, PVC and CPVC bag filter housings for compatible chemical, water treatment and industrial liquid filtration applications.
Monarch Asia Pacific supplies non-metallic bag filter vessels for applications where corrosion resistance, chemical compatibility or non-metallic construction is preferred over stainless steel or carbon steel housings.
Non-metallic bag filter vessels provide a practical filtration option for compatible liquids where metal housings may not be the preferred choice. They are commonly selected for water treatment, chemical handling and industrial process applications where corrosion resistance and material compatibility are important.
These vessels are designed to hold standard filter bags or cleanable baskets, allowing suspended solids to be captured as liquid passes through the filter media. Depending on the application, non-metallic housings can be supplied in polypropylene, glass-filled polypropylene, PVC or CPVC materials.
Monarch can assist with housing material selection, filter bag or basket compatibility, chemical compatibility review, connection requirements, skid arrangements and practical installation considerations.
A non-metallic bag filter vessel is a liquid filtration housing manufactured from a compatible plastic or composite material rather than metal. The vessel holds a filter bag or basket and is installed in the process line to remove suspended solids from the liquid stream.
The non-metallic construction can provide advantages in selected chemical and water treatment applications, particularly where corrosion resistance or compatibility with specific process liquids is required.
Correct material selection is essential. The housing material, seal material, filter bag media and operating conditions should all be reviewed together before selecting a vessel.
Select from GFPP, PVC, CPVC and polypropylene filter housings for compatible liquid filtration duties.
Glass-filled polypropylene bag filter housing for compatible liquid filtration applications requiring increased rigidity and corrosion resistance.
PVC bag filter housing for compatible water treatment and chemical process applications where PVC is suitable for the liquid and operating conditions.
CPVC bag filter housing for compatible chemical and process liquid applications requiring a non-metallic vessel material.
Polypropylene bag filter housing for compatible industrial liquid filtration applications where a lightweight non-metallic vessel is preferred.
Non-metallic vessel material should be selected based on chemical compatibility, temperature, pressure and installation requirements.
| Material | Typical Selection Reason | Important Considerations |
|---|---|---|
| PP Polypropylene | General non-metallic filtration option for compatible liquids. | Confirm pressure, temperature and chemical compatibility before selection. |
| GFPP Glass-Filled Polypropylene | Selected where a more rigid polypropylene-based housing is suitable. | Check compatibility with the process liquid and operating conditions. |
| PVC | Often considered for compatible water treatment and chemical applications. | Temperature and chemical compatibility limits must be reviewed. |
| CPVC | Selected for compatible applications where CPVC offers advantages over PVC. | Confirm service temperature, chemical exposure and connection requirements. |
Non-metallic bag filter vessels are available to suit Size 01 and Size 02 filter bags or baskets. These common bag sizes allow the vessel to be selected around the required flow rate, solids loading and available installation space.
Depending on the application, vessels may be installed as a single simplex unit, as a duplex arrangement for changeover operation, or as part of a skid-mounted filtration package.
| Bag or Basket Sizes | Size 01 and Size 02 options |
|---|---|
| Connection Range | 1-1/4" to 4" nominal sizes, approximately DN32 to DN100 |
| System Types | Simplex, duplex and skid-mounted configurations |
| Media Options | Compatible filter bags or cleanable baskets depending on vessel and application |
These vessels can be used with disposable filter bags where simple changeout and a broad selection of micron ratings are required. In selected applications, cleanable baskets may be preferred where reusable filtration media or coarser straining is suitable.
The preferred media type should be selected by considering the liquid, required filtration result, particle type, solids loading, changeout frequency and pressure drop allowance.
A practical filtration option where chemical compatibility and corrosion resistance are key selection factors.
Non-metallic materials can provide an alternative to metal housings in compatible chemical or water treatment applications.
PP, GFPP, PVC and CPVC options allow the vessel to be selected around the liquid and operating conditions.
Vessels are available for Size 01 and Size 02 filter bags or baskets, supporting common industrial replacement media.
Systems can be configured for single-vessel operation, duty/standby service or skid-mounted filtration packages.
Bag filter vessels provide straightforward access for filter bag replacement or basket cleaning when installed with suitable service space.
Monarch can assist with vessel material, bag media, compatibility, sizing and installation considerations.
Correct vessel selection depends on the chemical service, flow rate, temperature, pressure, solids loading, required filtration level and connection requirements. With non-metallic housings, material compatibility is one of the most important selection steps.
The vessel body, seals, filter bag media and any baskets or internal components should all be checked for compatibility with the process liquid. Pressure and temperature limits should also be reviewed carefully for the selected material.
Non-metallic bag filter vessels are commonly used where suspended solids need to be removed from compatible liquids and a corrosion-resistant housing material is preferred.
