Designed for maximum oxygen uptake, our ProAir™ 4 Weighted Diffuser incorporates high-efficiency, low-maintenance, membrane sticks to release tiny oxygen bubbles into the water column. Membrane diffusers possess the synergy of air stones without the headaches of cracking and acid-washing. The ProAir™ 4 Weighted Diffuser has an integrated check valve to prevent back pressure on the compressor. The innovative sled design keeps the ProAir™ 4 submerged while maintaining an upright position during installation.


  • Size: 4 membrane
