Buying Guide: Key Purchase Considerations
What size grease interceptor do I need?
Assess your kitchen’s total discharge flow, including sinks, pot washes, and dishwashers. A higher GPM rating provides capacity for peak service but requires more space and cost.
Which material is best for my facility?
Steel interceptors are common and durable; stainless steel offers corrosion resistance and easier cleaning in harsh environments. Plastic units are lighter and often easier to install but may have different durability profiles.
What maintenance features matter?
Removable internal baffles, easy-access lids, and straightforward cleanout design reduce downtime during service. A trap with a simple filter or screen helps prevent solids from passing through.
Is certification important?
PDI certification ensures certain performance and safety standards. It can simplify local code approvals and ongoing compliance in many regions.
How does installation space affect choice?
Heavier and larger units require more space and often floor or pit support. Verify dimensions and access routes before ordering.
What is the best option for high-flow kitchens?
For high-volume settings, choose 50 GPM or higher with substantial grease capacity (100 lb or more) and robust maintenance features. These are better suited for chains, hotels, and large cafeterias.
