1. Product Introduction：

The CA11-9 is a standardized, high-efficiency liquid/gas coalescing filter cartridge designed to remove sub-micron liquid aerosols (oil and water mists) and solid particulate contamination from compressed air, gases, and certain light hydrocarbon liquids (e.g. aviation fuel, diesel).

As a "standard length" filter in the widely adopted CA (Coalescing) series, it’s model number directly indicates its key physical dimensions: a nominal 11 cm (≈2.75 inches) outer diameter and a 9-inch (229 mm) length. The CA11-9 typically features industry-standard mounting interfaces such as G3" ISO threads or flat gasket seals, ensuring direct interchangeability across a wide range of filter housings from multiple manufacturers.

2. Features/Benefits:

• (High-Efficiency Coalescing): Utilizes a multi-layer, fine glass fiber or synthetic media treated with special resins. This design effectively captures, merges (coalesces), and drains sub-micron oil and water droplets, delivering outlet air with extremely low contaminant levels (often ≤0.01 ppm w/w oil).

• (Superior Solid Particle Filtration): Simultaneously removes fine solid particles, typically rated at 0.01 or 0.03 micron, protecting downstream equipment and processes.

• (High Flow Capacity & Low Initial Pressure Drop): The optimized media structure provides a large filtration area relative to its size, resulting in low initial pressure drop. This maximizes energy efficiency and extends service intervals.

• (Robust Construction): Features a strong corrosion-resistant metal (aluminum or stainless steel) center core to prevent media collapse, and durable metal or polymer end caps with integrated seals (O-rings).

• (Broad Compatibility & Interchangeability): As an industry-standard size and interface, it has numerous direct and functional equivalents from major filter manufacturers (e.g. Pall, Parker, Donaldson, Domnick Hunter). This ensures easy sourcing, competitive pricing, and flexibility.

• (Reliable Service Life): Engineered for consistent performance and gradual, predictable pressure drop increase, facilitating proactive maintenance scheduling.

• (Optional Variants): Available in specialized versions, such as hydrophobic media for high-moisture applications or high-temperature seals for elevated operating conditions.

3. Application Areas：

    (Compressed Air Purification):

• Critical in the final stage of compressed air dryers (refrigerated or desiccant) to remove oil and water aerosols.

• Protects sensitive equipment: pneumatic tools, CNC machines, paint spray systems, instrumentation air, and food/beverage processing lines.

• Essential for producing Breathing Air (Grade D or higher) for SCBA systems and industrial breathing apparatus

(Industrial Gas Processing):

• Purification of instrumentation gases (N₂, Ar, He), process gases, and natural gas by removing pipeline liquids and particulates.

 (Fuel & Hydrocarbon Liquid Conditioning):

• Final polishing of aviation fuel (Jet A-1), diesel, and kerosene to remove free water and fine contaminants before engine or turbine injection, ensuring safe and efficient operation.

(General Industrial Manufacturing):

• Provides clean, dry air for automation controls, robotics, packaging machinery, and pharmaceutical manufacturing where moisture or oil can cause product defects or equipment failure.
