If you’re still running an older diaphragm-style windmill on your pond aeration system, it may be time for an upgrade. While those classic windmills served us well, the industry has shifted toward modern high-output, longer-lasting bellows compressors — and one of the best options on the market is the Joe Mescan Bellows Windmill Compressor (GEN-2).
Why Upgrade?
Bellows compressors offer several advantages over older diaphragm units:
-
More airflow
-
Higher oxygen output
-
Greater durability
-
Less maintenance
If your old tower is still structurally sound, there’s no need to replace the entire rig!
Universal Tower Adapter Sleeve Makes the Swap Easy
One of the biggest challenges for pond owners upgrading from older models has been fitting a new windmill top to an existing tower. Luckily, Joe Mescan offers a Universal Tower Adaptor Sleeve that solves this problem beautifully.

This sleeve fits a wide range of tower types — including Koenders, Superior, OWS, Beckermill, and more — and is often included free with the purchase of a GEN-2 windmill top. As the market quickly evolves away from old diaphragm-stye windmill compressors, It’s no wonder this is one of Joe Mescan’s best-selling products.
