1. Product Overview

CA11-5 is a compact and highly efficient Coalescing filter element with standardized design, belonging to the common CA (Coalescing Assembly) series products in the field of industrial filtration. This filter element is specially designed to efficiently remove liquid oil mist, water mist and sub-micron solid particles from compressed air, industrial gases and light fuel oil, and is a key filtration component for achieving deep fluid purification.

2. Primary Advantages

Exceptional Energy Efficiency (Core Advantage):

Extremely low initial pressure drop, combined with a gradual increase over its lifespan, significantly reduces the operating energy consumption of the compressed air system. For large-scale, continuous operations, the energy savings can be substantial, often offsetting the cost of the filter element itself within months.

Extended Service Life:

The large filtration area and optimized pleat design provide superior dust-holding capacity and liquid-holding capacity compared to conventional filter elements. This translates to longer operating intervals between changes, reducing downtime, change-out frequency, and overall maintenance labor and costs.

Excellent Filtration Performance:

Delivers high-quality air compliant with ISO 8573-1:2010 standards for oil, water, and particles, capable of achieving up to Class 1 (oil content ≤ 0.01 mg/m³). This is critical for industries with stringent air quality requirements such as precision instrumentation, painting, food & beverage, pharmaceuticals, and electronics.

High Reliability and Safety:

Bypass-free design: Ensures all air is thoroughly filtered. Even under high contaminant loading or when the media is fully saturated, unfiltered air cannot "short-circuit" through the element.

Robust construction withstands system pressure fluctuations.

Broad Compatibility and Application:

Suitable for precision filtration downstream of various compressors (e.g., rotary screw, piston) in lubricated or oil-free systems. Can be used for removing oil aerosols and moisture from lubricated compressor air, or for particulate and moisture removal from oil-free air.

Also applicable for filtering various industrial and instrument gases.

Superior Overall Cost-Effectiveness:

While the initial purchase price of a single CA11-5 element may be higher than that of a standard filter, its extended service life and significant energy savings result in a lower Total Cost of Ownership over the long term, making it a more economical choice.

3. Application Areas

Critical "Life Sciences" and "Precision Manufacturing" Sectors

• Food & Beverage Industry:

• Applications: Bottle blowing, filling, packaging, mixing, and product conveying where air contacts the product.

• Role: Removes oil, water, and particulates (which can harbor microbes) to ensure food safety, prevent spoilage, and comply with regulations like those from the FDA.

• Pharmaceutical & Biotechnology Industry:

• Applications: Conveying active ingredients, fermentation aeration, tablet coating, sterile packaging, lab instrument control.

• Role: Delivers air meeting ISO Class 1 or better purity, preventing oil and microbial contamination of products. A key component for GMP (Good Manufacturing Practice) compliance.

• Electronics & Semiconductor Manufacturing:

• Applications: Chip cleaning/purging, photolithography, PCB manufacturing, testing equipment.

• Role: Removes sub-micron particles and oil aerosols to prevent contamination that can cause circuit shorts, corrosion, or yield loss.

Core Manufacturing for Process & Product Quality

• Spray Painting & Coating Industry:

• Applications: Automotive, furniture, and metal product painting (wet and powder coating).

• Role: Provides absolutely oil- and water-free air to ensure a smooth, defect-free finish (prevents "fish eyes," "orange peel"), guaranteeing coating adhesion and gloss.

• Precision Instrumentation & Pneumatic Controls:

• Applications: High-accuracy pneumatic gauges, CNC machine controls, robotic actuators, sensitive valves.

• Role: Protects expensive, delicate instruments and components from corrosion, clogging, or failure caused by oil and water, ensuring production accuracy and reliability.

General Industry for Equipment Reliability & Productivity

• General Pneumatic Tools & Equipment:

• Applications: Pneumatic wrenches, screwdrivers, cylinders, and impact tools on production lines.

• Role: Reduces internal wear, prevents wash-out or emulsification of tool lubrication, significantly extending tool/equipment life and reducing downtime and maintenance costs.

• Instrument Air & Process Gases:

• Applications: Control valves, analyzers, and transmitter signal air in chemical plants, refineries, and power generation.

• Role: Ensures reliable and accurate control signals, preventing instrument malfunction due to contamination, which is vital for safe and stable plant operation.

• Plastics & Blow Molding:

• Applications: PET bottle blowing, plastic film extrusion, injection molding.

• Role: Prevents mold surface defects caused by oil, ensuring product clarity, surface finish, and consistency.

Other Specialized Fields

• Medical & Dental Equipment:

• Applications: Dental chairs, surgical tool drives, air supply for ventilators (often with additional sterile-grade final filters).

• Role: Provides a clean air source to protect patient safety and equipment.

• Printing & Packaging Industry:

• Applications: Printing press controls, paper handling, vacuum systems.

• Role: Prevents oil contamination of paper and printing plates, ensuring print quality.
