Metallic monofilament filter bag

Product description

Metallic mesh filter bag for extreme temperature and heavy duty liquid filtration

The Metallic Mesh Filter Bag is designed for demanding liquid filtration applications where polymer filter media cannot withstand the operating conditions. Manufactured from high grade metal mesh, these filter bags offer exceptional mechanical strength, reusability and extreme temperature resistance.

Metallic mesh filter bags are particularly suitable for processes involving very high temperatures, abrasive particles or aggressive mechanical conditions where conventional felt or monofilament filter bags would fail.

Filtration principle

Metallic mesh filter bags operate using surface filtration. Process liquid flows through a woven metal mesh structure, while particles larger than the mesh openings are retained on the surface of the bag.

This filtration principle provides:

• precise and repeatable particle separation

• very low pressure drop at high flow rates

• immediate visual inspection of retained solids

• excellent cleanability and reusability

Because particles remain on the surface, metallic mesh filter bags can be cleaned and reused multiple times without loss of structural integrity.

Material characteristics

Metallic mesh filter bags supplied by Filtra International are produced from high quality metal materials such as stainless steel or other high temperature resistant alloys.

Key material characteristics include:

• extremely high mechanical strength

• excellent resistance to abrasion

• dimensional stability under extreme conditions

• resistance to thermal shock

• long operational lifetime

• suitability for repeated cleaning cycles

Unlike polymer filter media, metallic mesh does not soften, melt or degrade at elevated temperatures.

Temperature performance and limitations

A key advantage of metallic mesh filter bags is their exceptional temperature resistance.

Typical temperature performance:

• suitable for continuous operation at very high temperatures

• capable of withstanding temperatures up to 800 °C, depending on material grade and process conditions

• suitable for hot oils, molten or semi molten process streams and extreme industrial environments

Important limitations:

• metallic mesh provides surface filtration only and does not offer depth filtration

• not intended for fine or absolute filtration duties

• selection of correct mesh opening and material grade is essential

For applications requiring fine particle removal, metallic mesh bags are often used as a pre filtration stage.

Design and construction

Metallic mesh filter bags are engineered for durability and operational reliability.

Typical design features include:

• woven metal mesh construction

• reinforced seams for mechanical strength

• integrated sealing ring or flange to prevent bypass

• compatibility with standard industrial support baskets

• compatibility with standard bag filter housings

The robust construction allows the filter bag to maintain shape and performance even under extreme operating conditions.

Filtration grades

Metallic mesh filter bags are available with defined mesh openings suitable for surface filtration and particle separation.
Exact filtration grades depend on mesh specification and material selection and are configured per application.

Filtra International supports correct mesh selection based on process requirements.

Standard sizes

Metallic mesh filter bags are supplied in standard industrial sizes to ensure compatibility with common bag filter housings.

Typical sizes include:

• Size 1

• Size 2

• Size 3

• Size 4
  

Custom sizes and special constructions are available on request.

Typical applications

Metallic mesh filter bags are commonly used in:

• high temperature liquid filtration

• hot oil and heat transfer fluid filtration

• abrasive slurry filtration

• chemical processing at elevated temperatures

• recovery and reuse applications

• heavy duty industrial filtration

• pre filtration before finer filtration stages

Key benefits

• Extreme temperature resistance up to 800 °C

• Exceptional mechanical strength

• Reusable and cleanable design

• Low pressure drop at high flow rates

• Precise surface filtration

• Long service life in harsh environments

• Compatible with standard bag filter housings

Important selection considerations

Metallic mesh filter bags should be selected based on:

• operating temperature

• fluid chemistry

• required particle separation level

• mechanical stress and abrasion

They are not a replacement for depth or absolute filtration media but are ideal where robustness and temperature resistance are critical.
