Airmax EasySet Weighted Airline

EasySet Weighted Airline is designed specifically for underwater use in pond and lake aeration systems. It rests directly on the pond bottom and will not float, even when fully pressurized, keeping diffuser placement stable and airflow consistent.

Built with a thick-wall, lead-free construction, this airline is fish-safe, kink-resistant, and durable enough for years of continuous submerged operation. It is the correct choice for delivering air from the shoreline connection to bottom-mounted diffuser plates.

Why Choose EasySet Weighted Airline?

• Stays Submerged: Self-weighted design keeps the airline firmly on the pond bottom.


• Durable Construction: Thick-wall material resists punctures, kinks, and wear.


• Fish-Safe: Lead-free construction suitable for ponds with fish.


• Clean Installation: Eliminates floating lines that interfere with pond aesthetics.


• Flexible Length: Can be cut to size easily during installation.

Installation Notes

• Underwater Use Only: Designed exclusively for submerged applications.


• Connection: Connects at the pond edge or to direct burial airline using a connector kit.


• Diffuser Connection: Attaches directly to diffuser plates on the pond bottom.


• Long Runs: Use 5/8" diameter for single runs over 300 ft or total system airline over 600 ft.

PRO TIP

Lay the airline loosely along the pond bottom without stretching it tight. Allowing a bit of slack helps prevent tension at fittings and makes seasonal adjustments or diffuser relocation much easier.
