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
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.
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
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
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
Semiconductor & Electronics: Cleanroom equipment, PCB manufacturing, chip assembly
Precision Instruments: Optical lens production, laser systems, analytical instruments
Medical Device Manufacturing: Assembly lines requiring Class 100-1000 clean air standards
Food & Beverage: Packaging machines, mixing systems, nitrogen blanketing
Pharmaceuticals: Tablet coating, blister packaging, fermentation air supply
Chemical Processing: Inert gas generation, catalyst protection systems
Breathing Air: Pre-filtration for SCBA systems and respirator air supply (with proper certification)
Pneumatic Controls: Robotics, CNC machines, precision valves in automated factories
Laboratory Applications: Instrument air, sample preparation, controlled atmosphere chambers
Central Compressor Rooms: Final polishing stage after refrigerated/dessicant dryers
Point-of-Use Protection: Critical equipment connections in lubricated compressor systems
