The Standard for Grease Filters for Exhaust Ducts

UL 1046 is the standard by which Grease Extractors are tested.

Products covered by these requirements are single-stage and multi-stage grease filters. These grease filters are intended for installation and use in accordance with the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, NFPA No. 96 and the International Mechanical Code (IMC).

CKV Hood Grease Filter Testing

The test methods described in this standard pertain to filters used in exhaust hoods for commercial cooking operations. The primary function of these devices and the capability of devices tested in this standard are to prevent flames from penetrating into the exhaust system beyond the hood collar.

The standard does not measure capture efficiency or physical robustness of the grease filter device or other factors that do not directly affect user or fire safety.

Note: Capture efficiency of a kitchen hood filter can be measured using ASTM F2519 “Standard Test Method for Grease Particle Capture Efficiency of Commercial Kitchen Filters and Extractors”.
