Coalescing separation oil filter – high-efficiency dehydration

1. Product Overview

Aite Coalescing & Separating Oil Filter is a high-performance oil purification system designed to address the harmful effects

 of water in hydraulic lubrication systems. Water presence causes oil oxidation, oil deterioration, reduced oil film thickness, 

decreased lubricity, oil denaturation and polymerization, viscosity changes, organic acid formation, metal surface corrosion, 

and reduced or lost dielectric strength of oil.

For traditional filtration and separation equipment, separating one liquid from another mixed liquid is particularly difficult. 

Aite Coalescing & Separating Oil Filter integrates precision filtration and high-efficiency dehydration – removing particle impurities, 

emulsified water, and free water from oil without damaging product quality. For oil containing large amounts of water, the separation 

effect is particularly significant, with separation speed several times to dozens of times faster than traditional methods.

As a professional manufacturer specializing in oil purification equipment and filtration solutions, we deliver Aite Coalescing &

 Separating Oil Filter with stable performance, reliable construction, and competitive pricing for industrial facilities worldwide.

2. Technical Principle

Aite Coalescing & Separating Oil Filter operates on the principle that different liquids have different surface tensions.

 When liquid flows through a hole, the smaller the surface tension, the faster the rate of passing through.

When different mixed liquids flow into Aite Coalescing & Separating Oil Filter, they first enter the coalescing filter element. 

The coalescing filter element has a multi-layer filter medium with pore size increasing layer by layer. Due to the difference in 

surface tension, oil passes through the filter quickly, while water passes much slower. Because the coalescing filter element 

adopts hydrophilic material, tiny water droplets are adsorbed on the surface of the filter layer, resulting in coalescence of water 

droplets. Under the action of kinetic energy, small droplets race through the opening and gradually converge into large droplets, 

which settle and separate from the oil under the action of gravity.

After oil passes through the coalescing filter element, there are still small water droplets moving forward to the separation filter 

element under the action of inertia. The separator element is made of special hydrophobic material. When oil passes through 

the separator element, water is kept out of the separator element, while oil passes through and is discharged from the outlet.

3. Usage Characteristics

Aite Coalescing & Separating Oil Filter delivers superior performance through the following key advantages:

Advanced Coalescing Separation Technology – Aite Coalescing & Separating Oil Filter applies advanced coalescing separation
