Coalescating dehydrated oil filter NAS6 Cleanliness

1. Product Overview

Aite HO Series Coalescing Dehydrating Oil Filter is specifically designed to solve the problem of excessive water content in various

 industrial oils – utilizing advanced coalescing separation technology to deliver efficient, reliable oil dehydration and particulate 

filtration. This high-performance oil filter is engineered for the purification of turbine oil, transformer oil, hydraulic oil, 

and lubricating oil – effectively removing both free water and dissolved water while simultaneously capturing solid particulate

 contaminants.

Aite HO Series Coalescing Dehydrating Oil Filter operates through a four-stage process – filtration, coalescence, sedimentation,

 and separation – achieving comprehensive removal of particle pollutants and water. This integrated design ensures that your 

hydraulic and lubrication systems maintain optimal oil cleanliness and dryness, extending equipment service life and reducing 

maintenance frequency.

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

Coalescing Dehydrating Oil Filter with stable performance, reliable construction, and competitive pricing for industrial facilities 

worldwide.

2. Working Principle – Four-Stage Dehydration & Filtration Process

Aite HO Series Coalescing Dehydrating Oil Filter operates through a carefully engineered four-stage process:

Stage 1: Filtration – Particle Contaminant Removal

Oil first flows from inside to outside through the coalescing filter element. The inner layer of the coalescing element features 

high-precision filter material that removes particle pollutants from the oil – including metal wear debris, dust, and other solid 

contaminants. This initial filtration stage protects downstream components and extends the service life of the coalescing media.

Stage 2: Coalescence – Water Droplet Growth

The coalescing filter element of Aite HO Series Coalescing Dehydrating Oil Filter is a suitable combination of glass fiber and 

other synthetic materials – specially prepared for oil dehydration with excellent hydrophilic properties. The outer layer of

 demulsification coalesces tiny water droplets suspended in the oil into larger droplets. This coalescence process transforms

 micro-dispersed water (which is difficult to remove) into larger droplets that can be separated by gravity.

Stage 3: Sedimentation – Gravity Separation

After coalescence, the larger water droplets rely on their own gravity to settle downward into the sedimentation tank. 

This natural gravity separation removes the majority of free water from the oil – significantly reducing water content before

 the oil reaches the separation stage.

Stage 4: Separation – Hydrophobic Barrier

The smaller water droplets that did not have time to settle are carried by the oil flow to the separation filter element. 

Aite HO Series Coalescing Dehydrating Oil Filter uses a separation filter core made of stainless steel mesh – with excellent

 hydrophobic (water-repelling) properties. When the oil flows through the separation filter element from outside to inside,

 small water beads are intercepted and blocked outside the filter element – only allowing oil to pass through while repelling water. 

This final separation stage ensures that the outlet oil is clean and dry.
