Sealed filter system – reliable, efficient, and easy to maintain.

I. Product Overview

The Stainless Steel Bag Filter is a high-performance, professional-grade liquid 

filtration system engineered

 to deliver reliable solid-liquid separation across a broad spectrum of industrial applications.

 Constructed 

entirely from premium-grade stainless steel, the housing exhibits exceptional mechanical

 strength, 

outstanding corrosion resistance, and long-term structural integrity even under demanding

 operating conditions.

 The surface is meticulously finished through mirror polishing, precision embossing, 

or sandblasting — processes 

that not only enhance visual appeal but also minimize fluid adhesion and residue buildup,

 thereby facilitating rapid 

and thorough cleaning between service intervals.

At the core of the system lies a robust metal support basket, precisely fabricated to 

securely retain the filter bag in

 its optimal position. During normal operation, unfiltered liquid enters the vessel

 through the inlet port, flows 

uniformly across the full cross-section of the filter bag, and passes through the filter

 medium where suspended solids, 

particulate matter, and miscellaneous impurities are effectively intercepted. 

The clarified filtrate then exits through

 the outlet port, ready for subsequent processing stages or final use. By selecting

 filter bags with varying micron 

ratings — ranging from coarse straining to fine microfiltration — the system can 

achieve precise particle removal 

across different size spectrums, accommodating diverse process objectives including

 primary clarification,

 final polishing, product purification, and valuable solids recovery.

When the accumulated solids within the filter bag reach the predefined differential 

pressure threshold — typically

 indicated by a pressure gauge mounted on the housing — the unit is ready for bag replacement.

 The process is 

remarkably straightforward: the operator releases the quick-opening clamp or bolts, 

lifts the hinged or removable lid, 

withdraws the spent bag, inserts a fresh one, and reseals the vessel.

 This entire procedure can be completed within

 minutes, substantially reducing production downtime and enhancing overall

 operational efficiency.

The equipment features a space-saving, compact footprint that enables flexible

 integration into new or existing

 production lines with limited floor space. The fully sealed, closed-system design prevents 

liquid splashing, vapor 

emissions, or external contamination during filtration, ensuring a safe, clean, 

and environmentally responsible 

working environment. With its combination of robust construction, operational simplicity,

 energy-efficient performance,

and versatile adaptability, this bag filter represents an ideal multi-purpose filtration

 solution for industries ranging 

from chemicals and pharmaceuticals to food processing, electronics manufacturing, 

coatings production, 

and wastewater treatment.

II. Security Bag Precision Filter (Optional Configuration)

For applications that demand elevated filtration precision, ultra-fine particle removal, 

or specialized chemical

 compatibility, we offer the Security Bag Precision Filter — also commonly referred to as 

a precision filtration unit. 

While the housing is consistently manufactured from high-grade stainless steel to ensure 

durability and corrosion

 resistance, the internal filtration medium departs from conventional bag structures 

and accommodates a diverse

 array of tubular filter elements. The selection is meticulously customized based 

on the specific characteristics of the 

process fluid, targeted filtration rating, operating temperature, pressure profile, 

and chemical environment.

Available filter element options include:

PP Melt-Blown Elements Thermal bonding process; depth-type cartridges with

 graded pore structure; high dirt-holding 

capacity; cost-effective for general industrial filtration

String-Wound Elements Continuous yarn wound around a perforated core;

Each element type undergoes rigorous quality testing to ensure consistent performance,

 and our technical team 

provides comprehensive selection guidance to match the optimal element configuration

 to your unique process

 demands.

FAQ (Frequently Asked Questions)

Q1: What is the difference between the standard Stainless Steel Bag Filter and the Security Bag Precision Filter?

A: The standard bag filter uses filter bags (felt, mesh, or monofilament) as the filtration medium 

and is ideal for general solid-liquid separation, primary clarification, and polishing. 

The Security Bag Precision Filter (optional configuration) uses tubular filter elements

 (melt-blown, string-wound, pleated membrane, titanium porous, or activated carbon)

 to achieve higher precision, ultra-fine particle removal, or specialized chemical compatibility

 for more demanding applications.

Q2: What filtration precision can this system achieve?

A: The system accommodates a wide range of micron ratings—from coarse straining to fine microfiltration. 

When configured with pleated membrane elements, it can achieve absolute filtration ratings down 

to sub-micron levels, making it suitable for high-purity applications such as pharmaceutical and 

electronics manufacturing.

Q3: What materials are used for the filter housing and wetted components?

A: The housing is constructed entirely from premium-grade stainless steel with surface finishing 

options including mirror polishing, precision embossing, or sandblasting. All wetted components 

are fabricated from high-purity, inert materials that resist fiber shedding, extractables,

 and chemical leaching—critical for food, beverage, and pharmaceutical applications.

Q4: How easy is it to replace the filter bags or elements?

A: Very easy. The system features a quick-opening clamp or bolt design with a hinged or removable lid. 

The operator can withdraw the spent bag/element, insert a fresh one, and reseal the vessel within 

minutes—substantially reducing production downtime and enhancing overall operational efficiency.

Q5: How do I know when to replace the filter bag or element?

A: A pressure gauge is mounted on the housing to continuously monitor the differential pressure. 

When the accumulated solids reach a predefined pressure threshold, it signals that replacement is due. 

This allows for timely maintenance based on actual operating conditions rather than fixed schedules.
