Replacement for 1930253131 / DB2132 / 91111-005 / 9610112-20901-M / QGN001-050-170305 / 2205406504 / BLT60A
High-Efficiency Oil-Air Separation for Screw Air Compressors
Factory Direct Supply | OEM Available | Industrial Filtration Expert
The 4930253131 / 2205406503 air oil separator element is a high-performance oil-air separator filter designed for rotary screw air compressors. It ensures efficient separation of oil from compressed air, delivering clean air output with extremely low oil carryover.
This model is widely used as a replacement air oil separator element compatible with multiple compressor brands and systems.
✔ Oil Content ≤ 3 ppm
✔ Low Pressure Drop ≤ 0.2 bar
✔ Service Life up to 4000 Hours
✔ OEM-Compatible Replacement
Product Overview
The air oil separator filter element is installed inside the oil separator tank of a screw compressor. It performs the critical function of separating oil from compressed air before discharge.
This ensures:
· Clean compressed air output
· Reduced oil consumption
· Stable compressor operation
· Protection of downstream equipment
It is one of the most critical air compressor spare parts.
Compatible & Equivalent Models
This air oil separator element is compatible with:
· 4930253131
· 2205406503
· 2205406504
· 1930253131
· DB2132
· 91111-005
· 9610112-20901-M
· QGN001-050-170305
· BLT60A
Suitable as a universal replacement oil separator for screw compressors.
Why Oil-Air Separation Is Important
In a screw air compressor, lubricating oil is injected into the compression chamber for:
· Lubrication
· Cooling
· Sealing
After compression, the air contains oil mist. Without effective separation:
❌ Oil will enter downstream equipment
❌ Increase oil consumption
❌ Contaminate compressed air
❌ Reduce system efficiency
A high-quality air oil separator filter is essential for clean air output.
How Air Oil Separator Works
1. Oil-Air Mixture Enters Tank
Compressed air mixed with oil enters the separator vessel.
2. Primary Separation
Gravity and centrifugal force remove large oil droplets.
3. Fine Filtration
The separator element captures fine oil mist using fiberglass media.
4. Oil Recovery
Separated oil returns to the lubrication system.
This ensures efficient oil reuse and clean air output.
Advanced Separation Technology
Multi-Layer Fiberglass Media
Captures micron-level oil particles.
Deep Filtration Structure
Ensures high efficiency and long service life.
Low Pressure Drop Design
Maintains system efficiency and reduces energy loss.
Oil Carryover Explained
Oil carryover refers to the amount of oil remaining in compressed air.
· High-quality separator: ≤ 3 ppm
· Poor-quality separator: higher oil loss
Low oil carryover means:
✔ Cleaner compressed air
✔ Lower oil consumption
✔ Reduced maintenance cost
Pressure Drop & Energy Efficiency
Pressure drop is a key performance indicator.
· Low pressure drop → energy efficient
· High pressure drop → increased power consumption
A high-quality air oil separator element can reduce energy costs significantly.
Product Structure
The oil-air separator element is built with:
· High-efficiency fiberglass media
· Reinforced metal support
· Anti-corrosion end caps
· High-quality sealing gasket
Designed for durability in industrial environments.
