Max-Air™ Livewell Venturi Aerator



  • Most efficient aeration system available
  • Injects outside air into livewell lower than traditional spray heads
  • Inlet can be placed anywhere above waterline (exposed or concealed)
  • System requires 1/8" tubing (speedo tubing is recommended)
  • Fits 3/4" Hose

The Max-Air™ Venturi Livewell Aeration System draws fresh air from outside the livewell and injects tiny air bubbles into the water flowing into the livewell. With the aerated water entering the well at a lower level than with traditional spray heads, the entire well is more thoroughly aerated. The reduced restriction of this fitting allows more water to flow from the pump than traditional spray heads. The faceplate inlet can be mounted anywhere above the waterline (exposed or concealed).

Independent marine biologist testing shows that this type venturi livewell fitting is the most efficient aeration system available.

Works great....slightly worried about longevity

This venturi works perfectly as advertised. I am using it for a shad bait tank paired with a filtration system. I chose it over the Dannco version due to cost. I've never had a Dancco on hand to compare directly but the quality of the THMarine one appears to be less robust. It almost looks 3D printed. Should work fine in a traditional livewell setup where the venturi tube and most of the nozzle is in an area of the boat protected from damage and UV rays but probably suspect if in an area it could be bumped or something. Overall good buy and way better than a basic spray head.

Fragile inlet tube

This Venturi tube is small and fragile. It should have some gussets or larger radii at the base to keep it from breaking.


Just What I Needed to Finish My 14 Gallon Live Well Project

Fantastic air bubbles

Very good quality puts out a lot of air bubbles. Keeps my catfish lively through the whole night along with my bait fish highly recommended puts out air bubbles more than the stock aerator

Great Product

In this hot Texas summer killing fish becomes unintentionally easier. The Venturi Aerator helps keep the water in the live well moving helping keep the fish breathing properly.
