Activated Alumina Desiccant is a very porous form of aluminum oxide of high surface area which adsorbs liquids and gases without any change in form.

Activated Alumina is resistant to thermal stock and abrasion and will not shrink, swell, soften nor disintegrate when immersed in water

Activated alumina as a desiccant, will work by adsorption. The water in the air will stick to the alumina as the air passes through it. The water molecules become trapped so that the air is dried out as it passes through the filter. This process of regenerating the alumina is achieved when the activated alumina desiccant is heated, it will let go of all of the water stored in it, allowing it to be used over and over.

Nearly all gases and liquids can be dried with Activated Alumina. Water removal is often necessary for efficient processing, storage and transportation of fluids. Activated alumina is rapidly becoming the industry standard for drying compressed air. Providing long service life with performance at or below dew point specifications
