Product Details
1. Media Structure and Separation Mechanism
The element uses multi-layer gradient-density composite fiber material (fiberglass and polyester). Oil mist particles are captured via inertial impaction, direct interception, and diffusion adhesion. The inner high-precision layer ensures fine capture, while the outer layer pre-filters larger particles, balancing dust-holding capacity and service life.
2. End Cap and Sealing Design
End caps are made of quality metal with anti-corrosion surface treatment, suitable for humid or mildly acidic or alkaline environments.
Sealing rings use oil-resistant and temperature-resistant rubber, ensuring tight fit inside the oil reservoir to prevent bypass leakage.
3. Fluid-Optimized Internal Structure
The internal flow channels and support structure are designed based on fluid dynamics to reduce airflow resistance and turbulence, lowering overall pressure drop and improving compressor energy efficiency.
4. Pressure and Fatigue Resistance
The element maintains good collapse resistance under pressure fluctuations during compressor start and stop or load changes, ensuring no deformation or rupture over long-term operation.
5. Installation and Compatibility
This model features a standard industry interface and can be installed directly into corresponding oil reservoirs without modification. Compatible with most mainstream screw compressor systems, including stationary and portable types.
6. Applicable Conditions and Environments
Continuous or intermittent compressor operation
High-temperature and high-humidity environments
Dusty or mildly corrosive gas areas (pre-filter recommended)
Industries with oil carryover requirements: precision machining, painting, pneumatic instruments, food packaging, medical equipment, and more
7. Usage and Maintenance Recommendations
Clean the oil reservoir before installation and inspect the sealing ring for damage.
Monitor pressure drop changes after initial startup.
Replace based on operating hours or pressure drop indicator to avoid increased oil carryover.
When replacing, also check related components such as the oil return pipe and minimum pressure valve.
8. Quality Management and Consistency
The product is manufactured under standardized processes. Batch samples are tested for filtration performance and structural strength to ensure delivery consistency.
