I changed the air filter on my compressor, but it's still not pumping much air. Is it time for a maintenance kit?


A: Regular maintenance will extend the life of your compressor, but an air compressor can lose its pumping power for a number of reasons. To help deduce what the problem could be, start with a quick evaluation:

  • Is your air filter cleaned or replaced? (Check!)
  • Is your intake filter and aeration cabinet clean?
  • Have you checked the diffusers for clean membrane sticks?
  • Have you checked your airline for any loose connections?

If you've checked off these chores and your compressor is still low on the air flow, it might be time for a maintenance kit – especially if it's been a while since you've installed one.

Maintenance kits are available for both Shallow Water (diaphragm) and Shallow Water HP, PondSeries and LakeSeries deep water (piston) compressors. They include replaceable parts like O-rings, seals and hardware that'll get your compressor humming again. You'll need some basic tools, like a screw driver and Allen wrench, but they're fairly easy to install. Simply watch one of our kit installation maintenance videos (click the video tab on the maintenance kit page) and follow the included step-by-step instructions.

If you need specific replacement parts, like an air filter, diffuser stick or extra air line, be sure to check our inventory. Chances are good we'll have just what you need.

Waiting too long to install a maintenance kit could cause the compressor to become too worn, which will hasten the breakdown of those replaceable parts. Save your money: Take the time to maintain your current compressor instead of spending a pretty penny on a new one!

Plus, if you plan on running your aeration system this coming winter, do your maintenance now so you don't have to chip your system out of the ice in the middle of a cold snap.
