Gast 0523 Rotary Vane Applications

The Gast 0523 Rotary Vane septic air compressor is used on 500-750 GPD rated NSF Class 1 Standard 40 aerobic treatment systems (ATUs). The Gast 0523 compressors are also commonly used in pond aeration applications. With their ability to run continuously at 10.0 psi, they can pump to depths of 15-18 feet. This is much deeper when compared to the linear diaphragm pumps which can only push air to depths of 6 to 8 feet.

Why Choose the Gast 0523 Rotary Vane Septic Air Pump?

The Gast 0523 is a workhorse in the septic and pond aeration industry, known for its durability and performance in high-pressure applications. Here’s why it stands out:

• High-Pressure Capability: Handles back pressures up to 10 PSI, making it ideal for deeper diffusers (15–18 feet) compared to linear pumps (6–8 feet).
• Long-Lasting Design: Rebuildable vanes and minimal wear components ensure a 8–15 year lifespan, with rebuilds extending service life further.
• Low Maintenance: Requires only periodic filter cleaning (every 6 months) and vane replacement (every 3-5 years), with affordable rebuild kits.
• Pulse-Free Airflow: Delivers smooth, consistent air for efficient aeration, reducing strain on septic systems and pond ecosystems.
• Trusted Brand: Gast Manufacturing, Inc., a leader in rotary vane technology, provides reliable, UL-listed pumps made in the USA.
