CA33-9SB General Purpose High-Capacity Air Filter

The CA33-9SB is a premium, high-capacity coalescing filter cartridge engineered for demanding compressed air systems requiring maximum flow, extended service life, and superior contaminant removal. The "8-inch" length provides a substantially larger filtration area, making it the optimal choice for central filtration stations, high-consumption applications, and systems where minimizing maintenance frequency is critical.

Seal Material :

Nitrile (NBR) standard; Silicone (VMQ) optional

Media Type :

Multi-layer borosilicate glass fiber

CA33-9SB General Purpose High-Capacity Air Filter

Product Introduction

    1. Product Concept

    The  CA33-9SB is a high-performance multi-stage combination filter cartridge designed for advanced compressed air purification. It integrates dual-stage filtration technology within a standard 5-inch format: first-stage coalescing removes liquid aerosols and solid particulates, while the second-stage activated carbon bed eliminates oil vapors and odors. This integrated design provides comprehensive protection exceeding standard coalescing filters, targeting both visible and gaseous contaminants to achieve true oil-free air quality (≤0.01 mg/m³ oil content) as defined by ISO 8573-1 Class 1 standards.

    2. Key Features & Advantages

    Integrated Dual-Stage Technology

    • Primary Stage: High-efficiency borosilicate glass fiber media captures 0.01 µm oil/water droplets (>99.5% efficiency)

    • Secondary Stage: Impregnated activated carbon bed adsorbs oil vapors, hydrocarbons, and odors

    • Unified Construction: Stabilized media layers prevent channeling, ensuring sequential filtration

    Superior Performance Characteristics

    • Air Quality: Consistently delivers ISO 8573-1:2010 Class 0/Class 1 air for oil content

    • High Capacity: 40% larger adsorption surface area than standard 5-inch vapor filters

    • Energy Efficient: Optimized pleat geometry maintains <0.07 bar initial pressure drop at rated flow

    • Temperature Resilience: Functions effectively across 4-60°C operational range

    Operational & Economic Benefits

    • Extended Service Life: 2-3× longer change intervals compared to separate coalescing+vapor filters

    • Reduced Maintenance: Single cartridge replacement vs. multiple element changes

    • Space Optimization: Combines two filtration stages in one housing footprint

    • Cost Efficiency: 30% lower total ownership cost over 3-year operational cycle
