Grease Trap Sizing Tool

This sizing tool is to provide a product(s) recommendation based on two factors:

Maximum flow rate - Calculated based on each of the sink compartment dimensions and the number of additional fixtures (i.e. mop sink, hand sink, pre-rinse sink, etc.) connected to the grease interceptor.
Grease storage capacity - Calculated based on food type, serveware, customers per day, and pump out frequency.

Enter the various information below and a product(s) recommendation will be provided.

In the fields below, add the length, width, and height of each sink compartment. If all of the compartments are the same size, enter in the dimensions and select the number of compartments in your sink. Click ‘add sink with new dimensions’ if the size varies by compartment. Information for the pre-rinse sink is entered in the fixtures section.
