High Back Pressure Handling: Operates at up to 10 PSI, four times more than linear diaphragm pumps, perfect for systems with clogged diffusers or high resistance.
Oil-Less Design: Provides clean, contaminant-free air without lubrication, ensuring safe wastewater treatment and pond aeration.
Low Maintenance: Readily available repair parts like vane kits and filters simplify upkeep, keeping downtime to a minimum.

Gast 1023 Rotary Vane Applications

The Gast 1023 is vital for aerobic septic systems, supplying oxygen to support waste-breaking bacteria and producing clean, odorless effluent. Its high-pressure capability ensures reliable performance even in challenging conditions, preventing system failure. For pond aeration, it oxygenates water up to 18 feet deep, promoting a healthy aquatic environment. Without proper aeration, septic systems may turn anaerobic, leading to untreated effluent, while ponds risk algae growth and fish loss.
