Stainless Steel Bag Filter: compact, corrosion-resistant, high capacity, less downtime.

Product Overview

The stainless steel bag filter is an advanced precision liquid filtration system, manufactured from

 high-quality stainless steel with a mirror-polished, pressed, or sandblasted surface finish. 

Featuring a metal mesh basket that supports the filter bag, liquid flows in through the inlet, 

passes through the filter bag, and exits from the outlet, with impurities effectively captured inside the bag. 

This achieves the purpose of liquid filtration, purification, separation, and recovery. The filter bag can be easily 

replaced for continued use.

With a novel and compact structure, flexible and simple operation, energy-saving efficiency, and a sealed

 working environment, this versatile filter is suitable for a wide range of applications.

FAQ (Frequently Asked Questions)

Q1: What filtration precision can this stainless steel bag filter achieve?

A: The system can achieve filtration precision up to 0.5 μm, making it suitable for fine filtration

 applications across chemical, pharmaceutical, electronics, and food & beverage industries.

Q2: How does the sealing design prevent side leakage?

A: The system features an advanced sealing design that minimizes bypass and side leakage, 

ensuring that all process liquid passes through the filter bag rather than around it. 

This guarantees consistent and reliable filtration quality batch after batch.

Q3: How often do I need to replace the filter bags?

A: Filter bags do not need to be replaced on a fixed schedule. Replacement is required 

when the accumulated solids reach a predefined differential pressure threshold

 (typically indicated by a pressure gauge). The bags can also be cleaned and reused multiple times,

 significantly reducing consumable costs.

Q4: Is it difficult to change the filter bags?

A: Not at all. The system features a simple structural design with quick-opening clamps or bolts. 

Bag replacement can be completed within minutes without the need to clean the filter 

housing—saving both time and labor costs.

Q5: Can the filter bags be reused, and how many times?

A: Yes. The filter bags are cleanable and reusable for multiple cycles, depending on the contaminant 

type and cleaning method used. This reusable design dramatically lowers consumable costs

 over the equipment's lifespan.

Q6: What is the pressure loss across the system?

A: The system is designed for low pressure loss, which translates to lower energy consumption 

and reduced operating costs. The advanced hydrodynamic design minimizes resistance while maintaining 

high filtration efficiency.

Q7: What is the dirt-holding capacity of this filter system?

A: The system offers a high dirt-holding capacity within a compact footprint, enabling extended

 service intervals and reducing the frequency of bag changes—saving valuable installation space and maintenance time.

Q8: What materials are used for the filter housing and finish?

A: The housing is constructed from high-quality stainless steel with multiple finish options available: 

mirror-polished, pressed, or sandblasted. These finishes not only enhance visual appeal but also minimize

 fluid adhesion and residue buildup for easy cleaning.

Q9: What support structure is used for the filter bag?

A: The system includes a metal mesh basket that securely supports the filter bag in its optimal position, 

ensuring even flow distribution across the entire bag surface and preventing bag collapse under pressure.

Q10: What industries and applications is this bag filter best suited for?

A: The stainless steel bag filter is widely used across numerous sectors, including:

· Chemical Industry – filtration of chemical liquids, solvents, and coatings

· Food & Beverage – clarification of fruit juices, alcoholic beverages, edible oils, and syrups

· Pharmaceutical – filtration of medical liquids, purified water, and cleaning solutions

· Electronics – filtration of high-purity water, chemicals, and cleaning agents

· Water Treatment – pre-treatment of industrial wastewater, circulating water, and cooling water

· Petrochemical – filtration and recovery of oils, additives, and intermediates
