ProLake Diffused Aeration System for Ponds and Lakes From 1 to 16 Acres
The Keeton ProLake is a bottom-diffused pond aerator for ponds and lakes from 1 to 16 surface acres. A sound-deadening cabinet on shore houses one to four ½ HP AerFlow™ compressors that push air through weighted airline to Duraplate™ diffusers on the pond bottom. The rising bubbles circulate the whole water column, raising oxygen, cutting muck and algae and protecting fish year round.
• Sized to Your Pond: ProLake 1.1 to 4.16, with 1 to 16 diffusers. Each diffuser covers about 1 surface acre.
• 115V or 230V: every model comes in either voltage at the same price.
• Weighted Tubing Option: ProLake 1.1–1.4, 2.5 and 2.6 can include ½″ Alpine™ self-weighted airline, 100 ft per diffuser (100 to 600 ft in total).
• Duraplate™ Diffusers: fishhook-resistant, self-cleaning and non-clogging, with a lifetime warranty.
• Quiet, Protected Cabinet: sound-deadening cabinet with cooling fan, programmable timer, manifold and pressure gauge.
• ProLake 1 Cabinet Only: replace an existing ProLake 1 cabinet or pair it with your own diffusers.

Weighted Airline, Equipment Pad and Remote Manifold for Your ProLake Aerator
Alpine™ Self-Weighted Airline
Each diffuser needs its own run of weighted airline from the cabinet. Alpine™ ½″ airline sinks straight to the bottom, resists kinks and has a ¼″ thick sidewall. Sold in 100 ft boxes or a 500 ft continuous reel. The tubing option on ProLake 1.1–1.4, 2.5 and 2.6 includes 100 ft per diffuser; all other models ship without airline so you can order exactly what your layout needs.
Level-Aer™ Equipment Pad
A sturdy high-density plastic base for the cabinet, with no concrete or heavy construction needed. Small 24″ × 24″ for ProLake 1, Medium 30″ × 30″ for ProLake 2, Large 44″ × 32″ for ProLake 3 and 4.
ProLake Remote Manifold
Only needed when the cabinet sits several hundred feet from the water. Available in 4-valve and 8-valve versions. For a cabinet at the shoreline or about 100 ft away, run the airline straight from the cabinet.
Before You Order a Keeton ProLake Aerator

- Choose 115V or 230V to match the power at the cabinet location.
