    2. 4A-AB Air Brake System Molecular Sieve4A-AB air brake system molecular sieve is sodium aluminosilicate, and its crystal pore opening is 4 angstroms or 0.4 nm. It can be specialized in dryness of automobile air system, involving the water removal of automobile air conditioning system and air brake system.
    2. 3A-IGU Insulating Glass Molecular SieveSince it continuously and deeply adsorb the residual water and organic volatile in the interlayer of insulating glass, 3A-IGU insulating glass molecular sieve can effectively prevent condensation frosting phenomenon and remain smooth and transparent at very low temperature.
