Aspirator - Surface & Subsurface Industrial Aerator System
The Aspirator transfers oxygen from the water’s surface into the water column through a venturi tube, creating no surface spray. Available in floating Triton and subsurface Sub-Triton configurations.
Otterbine’s experience in wastewater treatment is obvious in the performance and results delivered by our surface and subsurface industrial aeration systems. Constructed from stainless steel, thermal plastics and a rugged low speed motor; these systems are built to withstand the demands of severe aquatic environments.
