Prolake Duraplate Diffusers for SolAer and Prolake Aeration Systems Both ProLake™ and Solaer® aeration systems utilize Duraplate™ self-cleaning, non-clogging membrane diffusers specifically designed to create a large amount of laminar circulation to eliminate stratification. Duraplate™ diffusers also deliver a very high oxygen transfer rate to increase dissolved oxygen levels at all levels in the pond from the bottom of the pond to the surface. Duraplate™ diffusers never need to be removed for cleaning like many of the other diffuser designs on the market, and are backed by a lifetime warranty. The rotationally molded Duraplate™ diffuser shell is also fishhook resistant, making them an ideal choice for fishing ponds and lakes. Duraplate diffusers also come in dual and quad set-ups for those larger jobs where single compressor layouts just aren’t enough.
