Air-Oil Separation 4930555181

4930555181 (New upgraded model: LE 49 001 x) is a high-end built-in air/oil separator filter element developed by MANN+HUMMEL of Germany specifically for industrial screw air compressors and vacuum pumps.

As the core barrier of the compressed air post-treatment system, it sets the industry benchmark in the field of industrial coalescing filtration.

Core Value: Why is it critical?

During the operation of the screw air compressor, the lubricating oil forms micron-sized fine oil mist mixed in the compressed air. This product is designed to thoroughly separate oil from air:

1. Extremely clean air: Control the residual oil content of the output air to ≤ 3 ppm, and prevent downstream pneumatic equipment, precision instruments and automated production lines from being contaminated by oil stains.

2. Greatly reduced operating costs: Efficiently recover lubricating oil and return it to the airend for recycling, prevent lubricating oil from being discharged along with the gas, and avoid frequent refilling of expensive compressor oil.

Four Core Highlights of the Product

1. German Coalescing Filter Media for Ultra-Low Residual Oil

Multi-layer composite high-density glass fiber coalescing filter media is adopted. As tiny oil mist particles pass through the filter screen, they rapidly coalesce into large oil droplets from fine particles via interception, collision and diffusion effects, and settle to the bottom of the filter element under gravity. It achieves a separation efficiency of 99.99% even for submicron oil mist smaller than 0.1 μm.

2. "Zero Spark" Full-Time Electrostatic Safety Protection

High static charges are generated when oil and gas flow and rub at high speed, which can easily trigger an explosion inside the oil-gas barrel.

The end cap, inner and outer metal frames and flange gasket of this filter element realize all-metal interconnection and conduction through a special process. Conductive shrapnel is embedded in the gasket, which can safely divert 100% of static electricity to the equipment ground after installation, completely eliminating the risk of electrostatic sparks.

3. Extremely Low Initial Pressure Drop for Remarkable Energy Saving

The optimized folding/winding process of Mann+Hummel enables the filter element to have a large flow area while maintaining high separation efficiency. The initial pressure drop ≤ 0.02 MPa. The air compressor does not need extra power consumption to overcome filter resistance, saving electricity costs for enterprises every operating hour.

4. Ultra-Long Service Life of 4000–6000 Hours

The frame and end cap are treated with deep anti-oxidation and anti-corrosion electrophoretic coating, resistant to high pressure, high temperature and acidic oil-gas environments. The robust metal inner liner can withstand a destructive pressure differential up to 20 bar. With routine maintenance, it delivers an ultra-long service cycle of 4000 to 6000 operating hours and reduces the frequency of shutdown maintenance.
