PAS20 Pond and Lake Aeration System for Up to 3 Acre

Model Number PAS20 Aerator Spec. ¾ HP Oil-free Piston Rocking Air Pump Voltage / Frequency 110–120 V AC / 60 Hz Power Consumption 550 W (≈ 6 A) Air Flow Rate Max 4.7 CFM @ 0 psi Max Working Depth Up to 65 ft (20 m) Coverage Area Up to 3 acres Noise Level 50–60 dB Weight Approx. 61 lbs (27 kg) – complete set Diffusers Two 10" EPDM membrane discs with 12" coated steel bases Airline Tubing Two × 100 ft self-sinking rubber hoses (5/16" ID, 5/8" OD) Operating Temperature For reliable performance: Open Space (e.g., garage/pavilion): Use a 6" 10 W ventilation fan to blow hot air away from the motor when ambient temperature exceeds 80 °F / 26 °C. Cabinet / Housing Installation: Provide at least two 6"–10" ventilation holes on opposite sides with dust filters, and use a 6" 34 W fan to exhaust hot air when temperature exceeds 50 °F / 10 °C. For best outdoor protection and optimal cooling, use the ASC01 housing, designed to match the PAS20 system perfectly. Maintenance Clean air filter every 1–3 months; Part Number: PAS20AFC; Inspect tubing and diffusers annually. Part Number: PAS20AL, PAS20AD. Check/Replace the rebuild kits in the pump to enhance the air tightness every 12-18 months. Part number: PAS20RB. Optional Enclosure If you’re unsure whether your setup provides enough ventilation for long-term use, consider our ASC01 outdoor housing. It’s designed to match the PAS20 system perfectly, supports outdoor installation, and greatly extends the air pump’s lifespan.

Balanced Ecosystem Algae and weeds stay under control with proper oxygen and circulation, keeping your pond naturally balanced and beautiful. Crystal Clear Water Aeration reduces nutrients and sludge, making the water bright, clean, and transparent from top to bottom. Healthy and Active Fish Higher oxygen levels support fish health, reduce stress, and let them swim freely without the risk of suffocation. Fresh and Odor-Free Air Circulation breaks the stagnant layers, prevents gas buildup, and removes foul smells for a fresh pond environment.

How the Pond Aeration System Works?

Long-Lasting and Reliable Air Pump Oil-Free Piston Design — No lubrication required for operation. Components — Equipped with Saint-Gobain piston cup and SCHAEFFLERZ bearings for extended lifespan. Optimized Cooling System — Works best with ASC01 housing for outdoor protection and temperature control. Self-Sinking Air Hose & EPDM Diffuser Set Durable Self-Sinking Tubing — 100ft 3/16" thick wall resists pressure, heat, and UV. Built for long outdoor use Thick EPDM Membrane Diffuser — Quality membrane resists stretch, deformation, and clogging. Coated steel base is stable, corrosion-proof, and easy to lift for maintenance.
