Product Description

Molecular Sieve Desiccant Used For Removing Water From Air-Braking Systems




Heavy vehicles such as trucks and buses use air to power their brakes. Air must be kept as dry as possible to avoid any freezing in the circuit but also any corrosion of the metallic parts.

Molecular Sieve 4a with high crush strength, abrasion resistance is specifically designed for air actuated brake systems to dehydrate the compressed air and keep brake lines from freezing and corroding.


Molecular sieve 4a is specially designed for air brake system.

Molecular Sieve 4a Air Break Desiccant is used especially for desiccation of air-actuated braking systems in cars, trucks, train and ship. Molecular Sieve 4a possesses the high strength and H2O adsorption capacity, the low dust contamination and attrition resistance required withstanding high vibration.
