1503F703AA is a high-efficiency air oil separator core specially designed for DENAIR high-power screw air compressors. As a core rear-end purification component in the air circuit system of the air compressor, it directly determines the quality of compressed air and the oil consumption rate of the system.
Core Functions
• Efficient Oil-Gas Separation: Captures fine suspended oil mist particles in compressed air, causing them to coalesce into oil droplets and flow back to the lubrication system.
• Reduced Oil Content in Exhaust: Strictly controls the oil content of outlet compressed air at ≤ 3 ppm to supply clean industrial air for downstream equipment.
• Lower Operating Costs: Adopts an ultra-low initial pressure drop design, which can markedly cut the power loss of the air compressor and realize energy and electricity savings.
Product Structure and Manufacturing Process
1. Imported Multi-layer Filter Media: The core filter layer adopts ultra-fine glass fiber composite filter media from HV (Hollingsworth & Vose), USA. It features extremely high filtration accuracy and chemical corrosion resistance, and is not prone to perforation or structural collapse.
2. Robust Metal Frame: Both inner and outer frames are made of high-strength thickened perforated steel plates with anti-corrosion galvanized or sprayed surfaces, capable of withstanding high pressure differential impacts.
3. Thickened Rubber Gasket: Equipped with high-performance oil-resistant and high-temperature-resistant sealing rings to ensure a 100% tight fit between the filter element and the air compressor base, preventing gas bypass leakage.
4. Built-in Static Conductive Sheet: The filter element flange is equipped with an anti-static grounding function, which can timely conduct static electricity generated by friction and completely avoid system flash fire or explosion caused by static sparks.
Installation Notes
Stop the system and release pressure before removal. Confirm flow direction and sealing surfaces before installation.
Maintenance & Replacement
Standard replacement cycle: Replacement is mandatory after a cumulative operating time of 3500 ~ 4000 hours. • Early replacement alert: If the oil separator pressure difference (DP) shown on the air compressor control panel reaches 0.08 ~ 0.1 MPa, immediate replacement is required even if the service time limit has not been reached. • Adjustment for harsh environments: If the air compressor operates in dusty, high-temperature environments (such as cement plants, textile mills, foundries) or high-humidity environments, it is recommended to shorten the replacement cycle to 2500 ~ 3000 hours.

Frequently Asked Questions
How do I confirm compatibility without a third-party brand reference?
Provide the product number, dimensions, connection details, operating conditions and equipment information. Our team will confirm the application.
Which dimensions should I measure?
Measure the overall height, outer diameter, inner diameter and thread or connection size. A photo or drawing helps confirm the replacement.
How do I choose the correct seal material?
Seal selection depends on the filtration media, operating temperature and chemical compatibility. We can confirm suitable options for your application.
Can you provide a product data sheet?
Yes. Send the product number and required specifications and we will provide the available data sheet and selection support.
