Blower Systems

Pedestal Models: Typically used for wastewater basins, can be suspended or set on the bottom of the basins from 10 to 30 feet in depth when 6-13 psi air is available. Customer can use their own air source or purchase optional blower. 

Floating Models: Typically used for small lakes, ponds, and wastewater basins. Varying length intake hoses are available to 30-plus feet. Customer can use their own air source or purchase optional blower.

Blower Systems: Available with output from 2.5 - 6 psi; blower units are mounted in a sound-reducing enclosure.

Air-Powered Mixers


GridBee AP Air-Powered Mixers and Circulators combine patented high-flow Long-Distance Circulation technology with a clog-free, air-powered pump. They have no moving parts in the water, offering years of maintenance-free operation even in high MLSS (mixed liquor suspended solids) applications. These machines feature an adjustable intake depth and are perfect for mixing activated sludge reactor basins, and other aerated and anoxic wastewater basins of all types and sizes. Because these powerful mixers are compact and lightweight, installation is well within the scope of work most cities can perform. The mixers have a fast payback in energy savings, and low-cost rentals are available.

Wastewater Benefits:

  • Energy-efficient; with the Air-Power unit doing the mixing, the aeration system can be turned down to provide just the needed dissolved oxygen (DO)
  • Cost-effective with or without the blower
  • Clog-free, self-cleaning design minimizes maintenance with no moving parts in the water

Lakes, Raw Water Reservoirs, and Estuaries Benefits:

  • Can be deployed for blue-green algae (BGA) control or hypolimnetic oxygenation
  • Aesthetically pleasing; mostly submerged except for float balls, can be easily disguised with artificial rocks or plants
  • Small footprint (6 feet diameter or less) reduces boating interference
  • No electricity in the water for swimmers; safer for humans and pets
  • Easy to mount on the end of docks
  • Excellent for de-icng marinas

Stormwater Benefits:

  • Thorough mixing provides increased detention and improved nutrient reduction
  • Effective control of blue-green algae and odors
  • No electricity in the water; safer for humans and pets
  • Low lifecycle cost when compared to fountains
