Ceramic microporous aerators are divided into two types: semi steel jade and full alumina. Semi steel jade aerators have the advantages of high efficiency, low consumption, reliable operation, less blockage, low resistance, large air volume, and strong agitation. Full steel jade aerators, alumina aerators, and trays are combined to form an integrated full steel jade type aerator head, which can prevent air leakage between ABS trays and alumina caps after prolonged use of semi steel jade aerators.
