Certifications

NFS Certification

We have received NSF Certifications for passing the industry standard ASME A112.14.3 (Grease Interceptor) and ASME A112.14.4 (Grease Recovery Device) tests. These are the same tests that IAPMO's UPC, and PDI's G-101 use for their certifications as well. These certifications were completed through NSF's Mechanical Plumbing Products Program and were tested for equipment performance in handling FOG in their new labs (built specifically for this purpose).
