Gas Duty Blowers and Vacuums

Sonic Air Blowers-Centrifugal Blowers and Models

Portable and Stationary Gas Duty Blowers and Vacuums

Sonic provides engineering support for many gas applications

Sonic offers gas-tight cast aluminum explosion-proof blowers ideal for landfill gas (LFG) sites, soil vapor extraction (SVE) applications, and hydrocarbon vapor recovery. Sonic’s gas duty blowers are hermetically sealed and can handle airflow rates from 100 to 2,000 standard cubic feet per minute (SCFM) and create vacuums/pressures up to 4 psig.

These gas duty blowers are available with welded 150# flanges or hermetically sealed designs for the most critical gas containment applications. Sonic also provides various electric and hydraulic drives, with water-cooled options rated for gas temperatures up to 400°F (200°C).

Designed for the Work Volatile Gases Require

Sonic’s Centrifugal Gas Duty Blowers and Gas Vacuums are built for high-demand industrial environments where combustible gas handling is critical. Sonic blowers produce pressure and vacuum to safely transport or extract volatile gases in controlled processes. Common gas blower applications include environmental remediation, soil vapor extraction, soil vapor recovery, hydrocarbon vapor recovery, flare gas booster, biogas collection, and specialized degassing systems. Designed for precision and reliability, these gas blowers and vacuums support continuous performance in hazardous areas while reducing operational risks and increasing energy efficiency.

Precision airflow for high-risk industrial settings

FEATURES

Thermal Management Capabilities: Optional water-cooled models allow for safe operation with gas temperatures reaching up to 400°F. Ideal for heat-sensitive or high-temperature gas processes.
Flexible Mounting Configurations: Available in both pedestal and cart-mounted designs to adapt to fixed or mobile operations. Makes integration into existing systems fast and cost-effective.
Gas-Tight Mechanical Design: Sealed internal pathways reduce leak potential and isolate external components from gas exposure. Especially beneficial in safety-regulated or emissions-sensitive industries.

BENEFITS

Reduces Equipment Downtime: With robust construction and fewer moving parts, these degassing systems stay operational longer between maintenance cycles. This saves time, lowers costs, and improves uptime.
Simplifies Environmental Compliance: Supports vapor containment and recovery protocols, helping operators meet EPA and local air quality standards. Built-in flexibility supports evolving regulatory needs.‍
Optimizes System Performance: Maintains stable airflow regardless of fluctuating pressure or gas density. Helps streamline operations and prevent energy waste.

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.
