Pharmaceutical Grade Stainless Steel
Respirator with SIP Capability
This Stainless Steel Respirator/Vent provides active protection for pharmaceutical
and bioprocess storage tanks. Consisting of a 304/316L stainless steel enclosure and
a hydrophobic filter cartridge, it efficiently removes particles and bacteria down to
≥0.01 μm during tank breathing. Designed with steam-in-place (SIP) capability for
repeated sterilization, the compact unit mounts directly on tank vents to deliver
GMP-compliant protection for WFI tanks, formulation vessels, purified water
systems, and fermenters.
Protects WFI and purified water tanks from microbial contamination during breathing, maintaining water quality stability
Provides sterile ventilation for fermenters, preventing bacterial contamination and improving product yield
PInstalled on formulation tank tops to prevent airborne contamination during liquid level changes
Ensures purity and activity of biological intermediates and finished products during storage
Provides cleanliness-grade ventilation protection for various storage tanks in critical process areas
Reliable Microbial Barrier
Hydrophobic filter media effectively blocks airborne microorganisms and particles, ensuring stored product quality and safety
In-Place Sterilization Capability
Full steam-in-place (SIP) design eliminates need for disassembly, maintaining sterile conditions during continuous operations
Broad Material Compatibility
304/316L stainless steel construction adapts to various process environments, with corrosion resistance ensuring long-term reliability
Easy Installation & Maintenance
Standardized connections and quick cartridge replacement significantly reduce maintenance time and operational complexity

How do I choose the right stainless steel pleated filter cartridge for my application?
Selection should be based on your process fluid, required filtration rating, operating temperature, flow rate, pressure conditions, cartridge dimensions, end-cap type, and seal material. For high-temperature, viscous, chemical, compressed-air, or liquid-cooling applications, these parameters should be evaluated together rather than selecting only by micron rating.
What micron rating should I choose for a stainless steel pleated filter cartridge?
The appropriate micron rating depends on the particle size to be removed, required downstream cleanliness, contamination load, flow requirement, and the role of the filter in the system. This stainless steel pleated filter cartridge is commonly available in the 5–200 μm range, with other ratings selectable according to specific process requirements.
Is this stainless steel filter cartridge suitable for high-temperature and high-viscosity fluids?
Yes, its all-metal sintered stainless steel construction is designed for demanding filtration conditions where polymer filter media may be unsuitable. It can be considered for high-temperature oils, resins, polymer melts, chemical intermediates, and other viscous fluids, provided the actual temperature, viscosity, pressure, and chemical compatibility are confirmed before selection.
How do I confirm chemical compatibility with my process fluid?
Chemical compatibility should be evaluated based on the stainless steel grade, seal material, fluid composition, concentration, operating temperature, contact time, and cleaning conditions. Available material and seal combinations may vary, so compatibility should be confirmed against your actual process conditions, especially when filtering corrosive chemicals, solvents, acids, or other aggressive fluids.
Can the stainless steel pleated filter cartridge be cleaned and reused?
The sintered stainless steel structure is designed to support cleaning and reuse under suitable conditions. Depending on the contamination type and process requirements, cleaning methods may include chemical cleaning or ultrasonic cleaning. Actual regeneration performance and service life depend on contaminant characteristics, cleaning procedure, differential pressure, and operating conditions.
Can this stainless steel filter cartridge replace my existing cartridge or fit my current housing?
Compatibility depends on the cartridge diameter, length, end-cap configuration, sealing method, and housing interface. Available configurations include multiple lengths, diameters, end caps, and seal materials. To confirm interchangeability, provide your current cartridge model, dimensions, end-cap type, filtration rating, process fluid, and operating conditions before replacement.
