Industrial Grade Excellence
Stainless Steel Vent Filter Housing Manufacturer & Supplier India | Sterile Tank Vent Filter
VVIOK Industry is ranked among the premier SS vent Filter Housing manufacturers India relies on for sterile gas, air, and tank venting solutions. Fabricated from certified AISI 316L and AISI 304 stainless steel with ultra-smooth electro-polished internal surfaces (Ra < 0.38 µm), each sanitary stainless steel vent filter housing ensures biosecurity for atmospheric and pressurized storage vessels. Designed in full compliance with cGMP and ASME BPE standards, our housings prevent airborne microbes, bacteriophages, and particulates from entering critical fluid storage during tank emptying and filling cycles.
Engineered specifically for sterile storage, our high-integrity tank vent filter housing assemblies feature sanitary tri-clamp connections, zero-dead-leg geometry, and optional electrical or steam heating jackets to prevent condensate blinding in high-humidity WFI (Water for Injection) loops. This makes each vent filter housing an essential safeguard in bioprocessing, dairy holding, and brewery fermentation systems. Furthermore, for critical sterile API formulation and aseptic manufacturing facilities, our Vent filter pharmaceutical solutions maintain ISO Class 5 air purity standards.
Beyond standard liquid holding vessels, our versatile fabrication capabilities extend to specialized exhaust and cleanroom air duct filter housing systems. Depending on your operational sterilization protocols, each vessel can be paired with 0.2-micron hydrophobic PTFE membrane elements or a rugged, regenerable SS Filter Cartridge for high-temperature clean steam and aggressive gas venting. Backed by rigorous 100% pressure and helium leak testing in Ahmedabad, Gujarat, VVIOK Industry delivers certified sterile venting systems worldwide.

Comprehensive Engineering Specifications for Stainless Steel Vent Filter Housings:
1. Metallurgy, Fabrication Standards & Sanitary Compliance:
• Wetted Contact Materials: Certified AISI 316L stainless steel ensuring maximum resistance against sanitizing agents, clean steam, and biocorrosion
• Non-Contact Components: Heavy-duty AISI 304 stainless steel tri-clamp band, wing-nut closures, and mounting brackets
• Sanitary Manufacturing Standards: Fabricated in accordance with ASME BPE (Bio-Processing Equipment), cGMP, and FDA 21 CFR regulations
• Surface Finishing: Internal surfaces mechanically polished and electropolished to Ra < 0.38 µm (15 µin); pickled and passivated for zero particle shedding
2. Venting Dynamics, Tank Protection & Headspace Equalization:
• Bidirectional Breathing Protection: Equalizes tank pressure during rapid filling (expelling air/gas) and rapid draining (drawing atmospheric air) without vessel implosion or overpressurization
• Microbial Barrier Integrity: Retains 100% airborne microbial contaminants down to 0.2 µm when fitted with hydrophobic PTFE sterile gas membranes
• Drainage & Condensate Management: Contoured bottom bowl with sanitary drain port and self-draining slopes to prevent fluid holdup and bio-film formation
• Condensate Prevention Jackets: Optional electric or steam trace heating jackets maintain element temperature above dew point, eliminating moisture condensation blinding
3. Cartridge Sealing & Internal Architecture:
• Adapter Style: Single Open End (SOE) Code 7 (226 double O-ring with 2 locking tabs and fin/spear) or Code 3 (222 double O-ring)
• Positive Hold-Down Ring: Ergonomic bayonet locking receptacle guarantees positive seal compression with zero risk of bypass under bidirectional flow
• Filter Element Versatility: Fully compatible with hydrophobic PTFE/PVDF pleated membrane cartridges and all-welded AISI 316L porous sintered or mesh elements
• Vessel Capacities: Compact single-round (1-round) models for small batch tanks; multi-round configurations (3 to 7 rounds) for massive bulk storage silos
4. Operational Ratings & Mechanical Dimensions:
• Maximum Working Pressure: Full vacuum (-1.0 bar) up to 10 bar (150 psi) positive pressure
• Test Pressure: Hydrostatically tested at 1.5 times the maximum design pressure (15 bar)
• Operating Temperature: Continuous operation up to 150°C (steam-in-place SIP and autoclave sterilizable up to 135°C)
• Connection Standards: 1", 1.5", 2", 2.5", 3", and 4" Sanitary Tri-Clamp (TC) ferrules (BS 4825 / ISO 2852), flanged ANSI B16.5, or threaded
5. Auxiliary Instrumentation & Quality Documentation:
• Vent / Gauge Ports: Optional 1/2" or 3/4" sanitary mini-TC port for pressure gauges, compound vacuum gauges, or sampling valves
• Gasket Formulations: Food & Pharma grade platinum-cured Silicone, EPDM, Viton (FKM), and PTFE compliant with USP Class VI
