When every cubic foot of air counts, precision airflow control is essential. Sonic Air Systems' industrial air diverter valves are engineered for high-performance blower and air knife systems that demand reliable, instant, and repeatable control. Designed for the harsh conditions of modern manufacturing, these valves help engineers optimize energy use, streamline production changeovers, and maintain consistent air delivery across multiple lines or processes. Whether you're routing airflow in a pneumatic conveying network, managing air rinse systems in food packaging, or diverting blow-off air in high-speed drying tunnels, Sonic's air diverter valves deliver uncompromising durability and accuracy.
The Sonic butterfly valve and Sonic Y-Verter™ provide a reliable mechanical alternative to electronic variable frequency drives (VFDs). They allow precise, real-time airflow management without added electrical complexity, helping operators regulate and redirect air between multiple paths while maintaining full blower efficiency, reducing motor wear, and improving overall energy performance.
Food Processing
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.
When specifying an industrial air diverter valve, consider the following engineering factors to ensure long-term reliability:
Installed after the blower discharge and paired with the standard blower inlet filter, Sonic’s inline HEPA filter makes a “True HEPA filtration” circuit that filters air for your knives or nozzles to 0.3 micron. It handles up to 1,000 CFM (28 CMM) at 2 psi.
See our options.
Motor starters, soft starters and variable frequency drives for Sonic blowers, mounted on the blower enclosure or custom built. Options include variable speed, soft start and stop, and fault monitoring for voltage irregularities and motor overloads.

A two-stage intake filter for dusty plants where Sonic’s standard cartridge loads up too fast. Two panel pre-filters trap large debris, then a 2 micron cartridge captures finer particles. Rated up to 1,100 CFM (34 m³/min).

Prepackaged mobile blowers on a chassis with 4 in (102 mm) casters, built to order with a complete blower enclosure. Options include motor starters or custom controls, wash down duty filter covers, a HEPA filter, a handheld blow-off nozzle and nozzle hoses in assorted lengths.
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.
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.
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.
Yes. They can be integrated with most industrial blowers or pneumatic systems, and custom configurations are available for unique operating conditions.
