airflow without deformation, ensuring a long service life.

  · End caps and center frame are made of electro-galvanized components, providing strong 

rust and corrosion resistance.

· Broad Adaptability & Stable Operation:

  · Wide operating temperature range: from -10°C to 100°C, suitable for diverse working

 conditions.

  · Flexible filtration accuracy: available from 1μm to 100μm to meet various application

 requirements.

  · High dirt-holding capacity: filtration ratio up to 200, extending maintenance intervals.

· Reusable: The filter media can be cleaned and regenerated, helping reduce long-term 

operating costs.

3. Operating Principles & Usage Guidelines

To ensure optimal performance and extend the service life of the filter element, please 

observe the following guidelines:

1. Oil Level Control: The lubricating oil level in the oil-gas separator barrel should be 

maintained between 1/2 and 2/3 of the oil sight glass, avoiding excessively high or low 

oil levels that may affect separation efficiency.

2. Unobstructed Lines: Ensure the secondary return oil line and check valve remain 

clear and are positioned correctly for proper oil circulation.

3. Pressure Adjustment: Adjust the discharge pressure to the specified rated value to 

prevent abnormal pressure fluctuations.

4. Temperature & Pressure Monitoring: During operation, ensure the compressor's exhaust

 temperature and pressure remain within normal ranges to guarantee system stability.

4. Typical Applications

This product is widely used in various industrial sectors, including:

· Surface Treatment: Painting equipment, powder coating, sandblasting operations

· Air Purification: Industrial dust collection systems, central air conditioning duct cleaning

· Fine Processing: Pigment industry, wood processing, filtration for food and pharmaceutical 

applications

· General Industry: Any production line requiring compressed air purification and dust collection

FAQ

Q1: What is the primary function of the 88290016-447SL filter element?

This high-performance filter element is designed for air compressors and industrial dust collection systems,

 effectively removing particulate contaminants from compressed air to ensure clean air supply for

 downstream equipment while meeting the demands of rigorous industrial environments.

Q2: What filtration precision and efficiency does this element achieve?

Manufactured from high-quality imported composite long-fiber spunbonded polyester non-woven fabric 

with uniformly distributed interlaced fibers, the element achieves a filtration precision of up to 0.3 microns 

and an initial filtration efficiency of 99.96% – effectively capturing submicron particles for high-purity applications.

Q3: What is the operating temperature range and available filtration ratings?

The element operates across a wide temperature range from -10°C to 100°C, suitable for diverse working 

conditions – with flexible filtration accuracy available from 1μm to 100μm to meet various application requirements, 

and a filtration ratio up to 200 for extended maintenance intervals.

Q4: What makes this element durable and long-lasting?

The element features excellent water and oil repellency, low pressure drop, high air handling capacity, 

and outstanding stiffness and abrasion resistance – capable of withstanding pulsed back-blowing airflow

 without deformation, with electro-galvanized end caps and center frame providing strong rust and corrosion

 resistance for a long service life.

Q5: Can this filter element be cleaned and reused?

Yes – the filter media can be cleaned and regenerated, helping reduce long-term operating costs while

 maintaining consistent filtration performance over multiple service cycles.

Q6: What industries and applications is this product suitable for?

This element is widely used in surface treatment (painting equipment, powder coating, sandblasting), 

air purification (industrial dust collection systems, central air conditioning duct cleaning), 

fine processing (pigment industry, wood processing, food and pharmaceutical filtration), 

and any general industry requiring compressed air purification and dust collection.

Q7: What are the key operating guidelines for optimal performance?

Maintain lubricating oil level between 1/2 and 2/3 of the oil sight glass, ensure the secondary return

 oil line and check valve remain clear, adjust discharge pressure to the specified rated value, 

and monitor exhaust temperature and pressure to keep them within normal ranges during operation.

Q8: How does this element compare to conventional filter elements?

The advanced composite long-fiber spunbonded polyester media offers superior submicron particle capture, 

higher dirt-holding capacity, better resistance to moisture and oil, and greater mechanical 

strength – delivering longer service life, lower pressure drop, and reduced maintenance frequency 

compared to conventional media.

Q9: What is the recommended replacement interval for this element?

Replacement intervals depend on operating conditions, dust loading, and system requirements – however, 

the high dirt-holding capacity (filtration ratio up to 200) and cleanable media significantly extend service life, 

with replacement typically indicated by increased differential pressure or reduced airflow rather than fixed time intervals.

Q10: Is this element compatible with existing compressor and dust collection systems?

Yes – the element is designed with standard dimensional specifications and interface configurations,

 enabling direct drop-in installation into most common air compressor and industrial dust collection housings 

without requiring system modifications.
