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:

Element Type Key Features

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; tapered pore gradient captures particles at 

varying depths; extended service life

Pleated Membrane Elements Maximized filtration surface area; high flow rates; minimal pressure drop; superior particle

 retention efficiency

Titanium Porous Elements Sintered from high-purity titanium powder; withstands extreme temperatures and strong 

corrosive media; cleanable via backwashing or ultrasonic methods

Activated Carbon Elements Combines mechanical filtration with adsorption; effectively removes residual chlorine, 

organic compounds, color bodies, and undesirable odors

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.

III. Performance Features

Our filtration systems are distinguished by the following key performance attributes:

Feature Description
