Republic Food Grade Air Knives

food grade air knife

REPUBLIC FOOD GRADE AIR KNIVES are engineered, manufactured and tested to provide liquid removal from meat, produce, food products, and food packaging using a high velocity, high impact air stream.

Specifically designed to comply with all USDA, 3-A, and ANSI/NSF/3-A standards, Republic's Food Grade Air Knives and Accessories are engineered for use in the meat, poultry, dairy, and food processing industries. Utilized in conjunction with a Republic Centrifugal Blower and a HEPA filter, the food grade air knife protects food surfaces from contamination during blow-off, drying, coating, and cooling applications. All of the air knife's surfaces are easily cleanable and designed to make necessary inspections straightforward.

Available in a variety of standard sizes, Republic's Food Grade Air Knives can be effectively utilized on nearly any conveyor, mixer, or processing equipment. Custom-engineered systems and air knives are also available.

Our breadth of manufacturing equipment allows us to engineer and manufacture the additional components needed to complete your system; including the Republic Centrifugal Blower, butterfly valves to provide the appropriate pressure and air stream as needed, elbows, Y-branches, and manifolds.
