Guaranteed Air Knife Solutions to Keep Your Production Line Flowing

Sonic provides a written performance guarantee on food and beverage systems with defined performance targets. Our systems provide a cost-effective and energy-efficient solution to moisture-related issues in food manufacturing, such as labeling, packaging, inkjet coding, date stamping, and other food and produce drying and blow-off production processes.

Food-grade air knife systems require stainless steel components and HEPA filtration. Sonic offers sanitary, 3A-compliant air knives that can be easily disassembled and cleaned by hand, ensuring food safety. Aluminum components are available for applications that do not require strict adherence to 3A guidelines but still require effective drying and blow-off capabilities. Our air knife systems are ideal for air rinsing, coating control, package drying, and other specialized applications across food and beverage production lines.

Improve Efficiency and Performance Across Every Stage of Production

Features

Sanitary Stainless Steel Air Knives: Provide a hygienic drying process that minimizes contamination risk in food and beverage production. Their smooth surfaces and easy cleaning support compliance with strict industry regulations.
HEPA Filtration: Removes microscopic particles from the air stream, ensuring a clean and sterile drying process for food and beverage products. This prevents contaminants from being introduced during drying, enhancing product safety and extending shelf life.
Sonic SMART Air Knife Tunnel: Modular stainless steel design expandable from 24” to 144” (61cm to 366cm), assembles onto almost any existing conveyor. Delivers enclosed, high-velocity air drying solutions for cans, bottles, and packaging. The tunnel design improves drying efficiency while containing moisture and debris to maintain a clean and safe production line.
Stainless Steel Blower Enclosures: For noise abatement, washdown protection, and sanitary requirements.
Accessories: Air knife brackets, connectors, and piping. Air knives from 6” to 144” (15cm to 366cm) long.

Benefits

Superior Drying Performance: With high-velocity, targeted airflow, Sonic’s air knife systems effectively remove moisture and debris from cans, bottles, and packaging. Consistent drying improves product quality and reduces issues during labeling, produce, food, and beverage manufacturing packaging, inkjet coding, and date stamping.
Enhanced Hygiene: Built with stainless steel components and HEPA filtration, they minimize the risk of contamination during the production and package drying process. This helps food and beverage manufacturers meet stringent sanitation requirements and maintain consumer confidence.
Improved Product Quality: Gentle and uniform drying prevents damage to delicate produce products and preserves their appearance, leading to higher quality and less waste. The precise airflow control minimizes product deformation and helps prevent spoilage, resulting in a more appealing and marketable final product.
Reduced Operating Costs: Compared to traditional drying methods, air knife systems consume less energy and require less maintenance, leading to substantial cost savings. The efficient blower technology minimizes energy consumption, while the durable components help reduce downtime and repair expenses.

How to Select the Right Industrial Diverter Valve

Determining the best valve for your system depends on balancing air volume, pressure, and material characteristics. When these factors align, you achieve smoother performance, higher efficiency, and long-term reliability. The ideal configuration not only maintains consistent airflow and minimizes pressure loss but also enhances energy efficiency across continuous production cycles.

Common Types of Diverter Valves

Flap Type Diverter: Simple, cost-effective valve ideal for low- to medium-pressure systems handling powders, pellets, or airflows requiring gentle redirection.
Plug (Rotor) Diverter: Designed for continuous-duty applications, offering smooth switching between lines with minimal leakage.
Slide or Slideflex Diverter: Provides fast, tight-sealing transitions for high-pressure or high-temperature processes where precision airflow management is essential.

Key Technical Considerations

When specifying an industrial air diverter valve, consider the following engineering factors to ensure long-term reliability:

Material Compatibility: Choose materials suited to your process: aluminum for lightweight efficiency, stainless steel for hygienic or corrosive environments, or coated alloys for chemical resistance.
Actuation & Automation: Sonic offers manual, pneumatic, or automated actuation to integrate with PLC or sensor-driven systems for instant airflow control.
Sealing & Maintenance: Valves are designed with precision-fit components and replaceable seals to maintain efficiency and reduce downtime during maintenance intervals.

Air Knife Tunnel and Enclosure

Bolt-together stainless steel air knife tunnels for drying bottles and cans before inspection, coding, labeling or packaging, at 100 to 1,500 products per minute. Standard modules are 24, 48, 72 and 96 in long, and sealed drip pans contain water and prevent rewetting.

Sonic ION-AIR Air Rinse and Air Wash Systems

Ionized air rinser and air wash systems that replace water rinsing and compressed air blow-off for cans, bottles and other products. Ionizing bars neutralize static so dust and particles let go, and blower power uses 75% less electricity than compressed air rinsing.

Reciprocating Air Knife (RAK) System

Air knives and nozzles that cycle up and down as parts pass on overhead monorail conveyors, so one Reciprocating Air Knife (RAK) system does the work of several stationary knives. Used for drying before coating and for shot blast blow-off on automotive, farm machinery and other large parts.

Cool Air Knife System

The Sonic Cool Air Knife System blows ambient or refrigerated air through high-velocity air knives to cool parts after welding, heat treating or thermoforming. It runs on a blower instead of compressed air and can replace or reduce water spray cooling and chilled cooling rollers.

Frequently Asked Questions

Entry level systems use hard anodized aluminum air knives paired with Sonic's centrifugal blowers, while premium systems step up to 300 series stainless steel, washdown duty components, and fully welded knives that meet 3A cleanability standards.

Yes. Sonic offers a written performance guarantee on food and beverage systems with defined performance targets.

In most cases, yes. Turnkey options include air knife tunnels, blower enclosures, and mounting accessories designed to integrate with a line you already have.

A food grade configuration typically pairs stainless steel air knives with HEPA filtration to remove microscopic particles from the airstream.

Air knives in this line run from 6 inches to 144 inches long, and the SMART Air Knife Tunnel expands from 24 inches to 144 inches, so a single system can typically flex across a range of can, bottle, and package sizes.
