AAL PFA Single Cartridge Filter Housing for Semiconductor Ultra-Pure Chemical Filtration Systems

The AAL APFA Series Single Cartridge Filter Housing is specifically designed for semiconductor manufacturing, ultra-high purity chemical delivery systems, and other critical applications requiring exceptional cleanliness, chemical resistance, and process reliability.

Manufactured from high-purity PFA (Perfluoroalkoxy) fluoropolymer, the APFA housing features a fully integrated one-piece construction that combines the housing body, cover, and connection fittings into a single molded unit. This innovative design minimizes potential leakage points, reduces installation space requirements, and provides superior sealing performance in demanding operating environments.

With its metal-free wetted construction, ultra-low metal ion extractables, and outstanding resistance to aggressive chemicals, the APFA Series is ideal for handling semiconductor-grade acids, alkalis, solvents, and specialty process chemicals used in wafer fabrication and microelectronics manufacturing.

To meet varying process requirements and budget considerations, the filter housing is also available in PVDF and PPH material options for industrial chemical filtration and general corrosive liquid applications.

Key Features

1. High-Purity PFA Construction

Manufactured from premium-grade PFA fluoropolymer, the housing delivers exceptional purity and contamination control for semiconductor and electronic chemical applications.

2. Integrated One-Piece Design

The housing body, cover, and fittings are molded as a single unit, significantly reducing potential leak paths while simplifying installation and maintenance.

3. Metal-Free Wetted Surfaces

All fluid-contact components are completely metal-free, helping prevent metal ion contamination and ensuring maximum process purity.

4. Outstanding Chemical Resistance

PFA material provides excellent resistance to:

· Sulfuric Acid (H₂SO₄)

· Hydrochloric Acid (HCl)

· Nitric Acid (HNO₃)

· Hydrofluoric Acid (HF)

· Ammonium Hydroxide

· Electronic-Grade Solvents

· Semiconductor Process Chemicals

This ensures long-term reliability in highly corrosive environments.

5. Excellent Thermal Stability

The PFA housing supports continuous operating temperatures up to 260°C (500°F), making it suitable for both high-temperature and high-purity chemical processes.

6. Ultra-Low Metal Ion Extractables

The high-purity fluoropolymer construction minimizes ionic contamination, helping protect sensitive semiconductor manufacturing processes and improve product yield.

7. Reliable Flare Connection Design

Precision flare fittings provide secure connections and dependable sealing performance under demanding process conditions.

8. Multiple Material Options Available

While PFA is the preferred material for semiconductor and ultra-pure chemical applications, the housing can also be supplied in:

PVDF (Polyvinylidene Fluoride)

· Excellent chemical compatibility

· High mechanical strength

· Suitable for industrial chemical processing

· Cost-effective alternative for many corrosive chemical applications
