Size:4A - Zeolite are available in beads of 1-2 mm(10x18 mesh), 2-3 mm(8x12 mesh), 2.5-5 mm(4x8 mesh) and as powder, and in pellet 1.6mm, 3.2mm.
XH-5 4A Molecular sieve for air brake system is specifically formulated for use in air actuated brake systems to dehydrate the compressed air and keep brake lines from freezing and corroding. 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. It has very high crush strength, abrasion resistance and water capacity allowing for long term use in air brake systems.

FEIZHOU molecular sieve Type 4A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes.To remove moisture from a 4A molecular sieve, a temperature of 250-280°C is required. A properly regenerated molecular sieve can give moisture dew points below -60°C.The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
