I highly recommend the Fountain Depot. Ryan and his team are incredibly knowledgeable and timely. We sought a floating fountain and underwater lights for our client, and Ryan delivered precisely what our client was desiring. The Fountain Place continues to maintain the fountain, and we have had zero issues.

I have had the pleasure of working with Ryan from Fountain Depot for the past year +. He designed and rebuilt our fountain from the ground up. They are a very knowledgeable team of guys. Our condo community could not be happier with the job they did for us. Highly recommend them for all your fountain needs.

Ryan and the team are truly exceptional - they really know their products and match that knowledge with amazing service. We have referred them to multiple friends for residential installations, and they have all shared the same positive experience as we have. Even when we had some repair issues, Ryan was quick to find a solution and get our fountain back to us in perfect condition.

If you have a pond, waterfall or fountain problem, I consider this THE place to go. I am a repeat customer over a decade, and highly recommend these folks. Ryan and his staff have made quick and creative-solution work of our pond and pump systems.
It follows from the diffuser count and depth, not from pond size alone. The KM-60 is 1/4 HP, the KM-120C is 1/2 HP and the KM-200 is 3/4 HP.
If you are replacing a compressor in an existing system, match what came out - the cabinet, manifold and tubing were sized around it. Send us the system model and we will confirm.
Should I rebuild or replace?
Rebuild first, in most cases. Kasco sells rebuild kits for the KM-60, KM-120 and KM-200, and a piston compressor that has lost pressure is usually worn rather than dead.
Pistons are wear items - Kasco does not cover them under the factory warranty, which tells you they expect them to be serviced rather than replaced.
How often does it need maintenance?
Change the air filter on a schedule and the compressor lasts far longer. A clogged filter makes the unit work harder and run hotter, which is what kills pistons.
Keep a spare filter element and a rebuild kit on the shelf - both are inexpensive against a mid-summer failure.
Can it run through a Canadian winter?
Yes, and on many ponds that is the point. The compressor sits on the bank in its cabinet, so nothing has to come out of the water before freeze-up.
Running through winter keeps an opening in the ice and lets trapped gases escape, which is what prevents winterkill.
How noisy is it?
It is a piston compressor running continuously, so it is audible up close. RobustAire cabinets use AireGuard noise-reducing construction to address exactly this.
On a residential shoreline, siting matters as much as the cabinet. We can advise on placement relative to the house and property line.
Do I need a cabinet, or can it sit outside?
It needs an enclosure. The cabinet protects the compressor from weather and provides the cooling airflow it depends on, and the fan is part of the design rather than an accessory.
If you are building a system from components rather than buying a complete RobustAire system, talk to us before you order - the pieces have to be matched.
