Each GAP-1398 DRIP PAN accommodates our specially designed GreaseDiaper that collects and traps up to several quarts of fats, oil and grease. Pan covers/lids are available and sold separately.


GreaseDiapers® are cost-effective to replace and maintain. GreaseDiapers® should be replaced as needed depending on the volume of FOG that is being generated. (12) Twelve GreaseDiapers® are shipped with each GAP-1398 DRIP PAN. Other quantities are available at discounted pricing.

The GAP-1398 DRIP PAN prevents overflowing FOG from spilling onto a clean roof and into storm drains.
