HQUA PAS20 Pond & Lake Aeration System – 3/4 HP, Up to 3 Acres, 100 ft Tubing

Overview

The HQUA PAS20 Pond & Lake Aeration System is designed to gently introduce compressed air into the bottom of a water body, promoting dissolved oxygen distribution and a clearer, more balanced water column. This setup presents a practical, non-medical approach to enhancing pond dynamics, offering potential improvements in water turnover and mixing in ponds that experience warming conditions or organic buildup.

Engineered for reliability, the PAS20 features a quiet, oil-less 3/4 HP rocking piston compressor paired with a durable diffuser network. It is capable of aerating ponds up to 3 acres and can reach depths around 65 feet, with the motor drawing roughly 6.2 amps and delivering about 4.7 CFM of air. These specifications support steady, consistent aeration across the water column without excessive noise or energy use.

What you get

• 3/4 HP oil-less rocking piston air pump
• Two air filters for cleaner airflow
• One outlet timer for scheduled operation
• Two 100 ft weighted rubber air hoses (5/16" ID, 5/8" OD)
• Two 10" EPDM non-stick membrane diffusers
• 12" square stainless steel diffuser base for stability
• Complete hardware: hose clamps and brass/barb fittings

Key benefits and setup possibilities

• Suitable for ponds up to three acres, offering scalable aeration as your water features grow
• Depth performance supports aeration across a substantial water column, up to about 65 feet
• Quiet, energy-efficient operation and oil-free design reduce maintenance concerns
• Included timer and filters help simplify routine use and airflow quality

Tips for installation and use

Plan diffuser placement near the pond bottom to maximize oxygen transfer, and route hoses to minimize kinks. Connect the included fittings securely and test the system at a shallow depth before full deployment. Regularly inspect the diffuser membranes and filters to maintain steady performance.
