The Thomas 617 Aeration Kit Wob-L Piston air system is compact and strong giving 1.16 cfm. @ 5psi and is only 1/7 hp. With up to 40 psi this pump can be used in ponds that are 30′ deep or run 2 air diffusers in 4-9′ of water. The 617 Kit is the right size to aerate and clean smaller ponds and reduce algae growth. Great for use in the winter to prevent fish kill and keep the pond open for swans, ducks, dock deicing or polar bear dips. The Thomas 617 Aeration Kit includes a 7″ round air diffuser, compressor, 50′ of 3/8″ weighted tubing, filter, and clamps. Everything you need for winter or summer water quality improvement.
It only takes a small 1/5 hp compressor to do the job. Matching the diffusers to the air output gives you millions of tiny bubbles rising to the top taking water with them. This airlifting is where the gas transfer takes place; oxygen goes in and foul gasses go out. Bottom aeration systems move massive amounts of water from the bottom of the pond (or lakeshore) to the top. This mixes oxygen throughout the whole pond and is the best type for swimming ponds. The Thomas 617 Aeration is great for ponds up to 100′.
