| 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 HQUA 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 HQUA ASC01 outdoor housing. It’s designed to match the PAS20 system perfectly, supports outdoor installation, and greatly extends the air pump’s lifespan. |
Algae and weeds stay under control with proper oxygen and circulation, keeping your pond naturally balanced and beautiful.
Aeration reduces nutrients and sludge, making the water bright, clean, and transparent from top to bottom.
Higher oxygen levels support fish health, reduce stress, and let them swim freely without the risk of suffocation.
Circulation breaks the stagnant layers, prevents gas buildup, and removes foul smells for a fresh pond environment.
What pond size and depth can this system handle?
The HQUA PAS20 system is ideal for ponds up to 3 acres in surface area and 65 feet deep. For best results, choose a system slightly larger than your pond size to ensure full aeration coverage and maximum oxygen circulation.
What’s included in the package?
Each kit includes a ¾ HP air pump, two 100 ft self-sinking air hoses (5/16" ID, 5/8" OD), and two 10" EPDM diffuser discs mounted on 12" coated steel bases. Everything you need for setup is included — no extra fittings required.
What’s the best working environment to help the air pump run safely and last longer?
For reliable use, add ventilation. In open areas, use a 6" 10 W fan when over 80 °F / 26 °C. In cabinets, add two 6"–10" vents with filters and a 6" 34 W fan when over 50 °F / 10 °C. For best results, use the HQUA ASC01 housing.
How loud is the system when running?
The air pump operates quietly at around 50-60 dB, similar to normal conversation. Rubber feet and internal shock absorbers reduce vibration noise. For ultra-quiet performance, install it inside a ventilated cabinet or shed.
What are the power requirements?
It runs on 110–120 V AC / 60 Hz, drawing about 550 W (6 A). A grounded outdoor outlet is recommended. Use a heavy-duty extension cord rated for outdoor use and sufficient current if the power source is far from the pond.
How soon will I see results in my pond?
Most users notice clearer water and increased fish activity within 7-14 days. Over time, aeration helps reduce sludge, odors, and algae buildup, improving overall pond health and water clarity.
How often should I perform maintenance?
Clean or check the air filters every 1–3 months. Clean or check the air diffusers annually. Inspect tubing for leaks annually. Check/Replace the rebuild kits in the pump to enhance the air tightness every 12-18 months. Part number: PAS20RB.
What makes this system different from others?
Our system uses the Saint-Gobain piston cup and SCHAEFFLERZ bearing for longer pump life. The hose is thick, pressure-resistant, and sinks easily. The diffuser uses a solid EPDM membrane, all built for outstanding durability and long service life.
Can I expand the system later?
Yes. You can add more diffusers or tubing using compatible HQUA accessories if your pond is large size and you want to improve the coverage. Part number: PAS20AL, PAS20AD. Each additional 100 ft air hose reduces the max depth by roughly 5.5–6.5 ft.
Is it safe for fish and plants?
Absolutely. The system provides gentle, continuous aeration that increases dissolved oxygen without disturbing fish or aquatic plants. It supports a balanced, healthy ecosystem year-round.
