MIFAB’s Big Max grease interceptor is manufactured from seamless, rotationally molded, high-density polyethylene (H.D.P.E.) for superior structural integrity and comes with an H-20 load-rated lid as a standard feature, MIFAB notes. Contractor friendly features include a narrow width to fit through doors and down stairways, and it can be carried by two people. The patented extension system is a standard ADS pipe cut to needed length. This unit comes in 75- and 100-gpm models and can be used alone or in a number of different combinations. Approvals include PDI, ASME, CSA and IAPMO.
