Pond Boss Forums AERATION Systems questions Gast 1023 pump - when to rebuild?

The smaller the surface area on the air filter and dirtier the air the more often the air filter should be changed. You can easily check the amount of clogging on the air filter is to with our mouth blow air through the filter from the compressor side connection. If you can very easily blow air through it, the compressor does not work hard to get air. Filter very likely is then okay. I like big filters on the compressors. A 1024 compressor sucks in around 74 gallons of air per minute!. Air can be dirty depending on conditions.
