In high-end fields such as semiconductor manufacturing, microelectronics, biopharmaceuticals, and fine chemicals, the purity and sealing integrity of fluid systems directly determine product yield and production safety. As a professional supplier in the fluid control industry, Shanghai AOKAVI Industrial Co., Ltd. (AOKAVI) is committed to providing customers with high-quality, highly reliable fluid filtration solutions.
This article introduces AOKAVI's core product line: the Stainless Steel Filter Series. Designed for demanding operating conditions, this series includes in-line, fully welded, and Ultra-High Purity (UHP) options, fully meeting the precision filtration needs of both gases and liquids.
I. Core Product Series
1. FE Series: In-line Filters (Replaceable Elements)
Designed specifically for piping systems with limited space, the FE series is renowned for its high flexibility.
Flexible Replacement: Supports replacement of sintered elements (nominal pore sizes of 0.5, 2, 7, 15, 60, and 90 μm) and pleated mesh elements (nominal pore sizes of 40, 140, 230, and 440 μm).
Rich End Connections: Offers multiple connection options including tube fittings, NPT female/male threads, and VCR face seal fittings, easily adapting to different pipelines.
Reliable Materials: The valve body utilizes SS316 stainless steel (The FE series standard is brass to meet different pressure requirements).
2. FWE Series: Fully Welded In-line Filters (Leak-Free Guarantee)
For applications with extremely high requirements for sealing integrity and dead volume, the FWE series provides the ultimate solution.
Fully Welded Structure: The body and element are fully welded, completely eliminating liquid retention dead zones, preventing micro-leak risks, and effectively preventing bypass flow.
Easy Reverse Cleaning: Supports reverse flow flushing for convenient maintenance.
Compact Design: Also suitable for space-constrained areas, offering 0.5 μm sintered and 2, 7, 15 μm pleated mesh element options.
3. GKE Series: Ultra-High Purity (UHP) Filters
Specially engineered for isostatic pressing sintering processes in the semiconductor industry and high-standard cleanroom environments.
Ultimate Cleanliness: The valve body is made of SS316L or SS316LVAR (Vacuum Arc Remelted) stainless steel. The gasket surface roughness is extremely low (Ra 5 μin).
Outstanding Performance: Filtration rating up to 0.3 μm, with filtration efficiency ≥99.99%. Helium mass spectrometer leak rate ≤1×10⁻¹⁰ Pa·m³/s, and particle shedding <1 particle/ft³.
Broad Operating Conditions: Supports 1/4" and 1/2" end connections; the maximum operating temperature for non-corrosive gases reaches up to 400°C.
II. Technical Analysis of Filtration Elements
AOKAVI offers a variety of internal filtration element solutions to handle different particle sizes and flow rate requirements:
Sintered Filtration Elements: 316L SS structure, intercepting particles down to 0.5 μm, providing high-strength depth filtration.
Pleated Mesh Filtration Elements: Utilizes a stainless steel structure (support mesh + filtration layer + support mesh), providing a larger filtration area and flow range compared to sintered types.
FW Series Dense Matrix Mesh: Made of 316 SS structure, the dense matrix mesh is specifically designed for filtering extremely fine particles.
III. Stringent Performance Parameters and Testing
Pressure and Temperature Ratings: Products are designed strictly according to standard structural materials. The FWE series can withstand a maximum operating pressure of up to 6000 psig (413 bar) at room temperature and maintains a pressure rating of 3280 psig (225 bar) at high temperatures up to 482°C.
Differential Pressure Capability: The maximum differential pressure for the FWE series sintered elements is 600 psig, and up to 1000 psig for the FE series.
Flow Performance: Optimized flow path design ensures high flow transmission at low pressure drops (refer to the flow data tables; supports both air and water media).
100% Helium Leak Testing: Every AOKAVI filter is helium leak-tested under a pressure of 1000 psig (69 bar) and meets the stringent requirement of no detectable leaks.
IV. Flexible Ordering and Customization Services
AOKAVI provides a clear model coding system, allowing customers to accurately select the right product based on their actual needs. For example: SVV-FWE4-V-2-T1
Body Material: SS (SS316L) or SVV (SS316LVIM-VAR).
Series Code: FWE4, FWES4, FE4, etc.
Filter Element Pore Size (μm): 0.5, 2, 7, 15 μm available.
End Connection: V = Male thread (solid).
Process Specification (Clean Packaging): Offers T1 (Standard clean packaging), T2 (Special clean packaging), and T3 (Ultra-high purity packaging) to meet the direct integration needs of production lines with different cleanliness levels.
