Patented Hot Air Blower for Drying Applications

While traditional duct heaters can achieve higher air temperatures, Sonic recognizes that few applications require the 300-600°F (149-315°C) ratings of duct heaters. Sonic engineers each application to meet specific drying or heating objectives, ensuring optimal performance rather than simply blowing hot air. Our exclusive heater-less design of Sonic's Hot Air Blower ensures safety and efficiency, delivering air flows of 100 to 2,000 CFM (2.8 to 56.6 m³/minute) and air pressures of 1 to 4 PSIG (6.9 to 27.5 kPa). This 21st-century technology is "intrinsically safe" compared to electric heater elements or gas-fired heaters reaching 1,200°F (649°C). And any component's temperature within Sonic industrial hot air blower models remains just a few degrees above the discharge air temperature.

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.

Frequently Asked Questions

Can Sonic butterfly valves be used with a Variable Frequency Drive (VFD)?

Yes. Sonic butterfly valves can operate in conjunction with a VFD for blower speed control; however, they can also function as the sole airflow control device. As a low-cost alternative to a VFD, the butterfly valve allows operators to manually fine-tune air velocity and pressure, setting the optimum airflow level during the initial system setup without relying on expensive electronic controls.

What is the Sonic Y-Verter™, and how does it differ from a VFD?

The Sonic Y-Verter™ is a mechanical alternative to Variable Frequency Drive motor controllers traditionally used in blower and air knife systems. It allows rapid, reliable airflow redirection between system branches without changing motor speed, reducing complexity and maintenance requirements compared to VFD-based systems.

When should I use a Y-Verter™ instead of a VFD?

A Y-Verter™ is particularly effective when using standard 3,600 RPM, 60 Hz motors where air control needs can be met through mechanical redirection rather than motor speed modulation. While certain high-speed blower motors (up to 20,000 RPM) may require VFDs with output frequencies up to 330 Hz, many air knife applications can achieve equal or better airflow management with the simpler, more durable Y-Verter™ system.

Are Sonic air diverter valves compatible with other blower systems?

Yes. They can be integrated with most industrial blowers or pneumatic systems, and custom configurations are available for unique operating conditions.
