Air Units

Pedestal Models: Designed for use in activated sludge wastewater basins, wet wells, lift stations, and industrial tanks and basins. Can be set on the bottom of basins to 50-plus feet in depth.

Floating Models: These machines offer an adjustable intake depth and float at that depth to achieve specific water quality objectives; up to 100 feet deep or more for hypolimnetic applications. they are designed for use in lakes, stormwater ponds, and wastewater ponds.

Air Units: Air blower units (low pressure) and air compressor units (high pressure) are available with an optional sound-reducing enclosure.

Air-Powered Mixers


GridBee AP Air-Powered Mixers and Circulators combine patented 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. Air can be supplied by the customer's existing system or by our optional on-shore air units. These powerful mixers are compact, lightweight, and easy to install by plant personnel, and with a low purchase price they have a fast payback in energy savings. Low-cost rentals are also available.

Other AP models are available for small lakes, stormwater ponds, and estuaries to achieve blue-green algae control and other water quality improvements. These units are barely noticeable in a lake, with only three small float balls and the flowing water visible from shore.

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)
  • Clog-free, self-cleaning design minimizes maintenance with no moving parts in the water
  • Cost-effective with existing air system or option air unit

Lakes, Raw Water Reservoirs, and Estuaries Benefits:

  • Can be deployed for blue-green algae control or hypolimnetic oxygenation
  • No electricity in the water for swimmers; safer for humans and pets
  • Small footprint (6 feet diameter or less) reduces boating interference
  • Aesthetically pleasing; easily disguised with artificial rocks or plants
  • 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

Electrical Service (Required for optional air units):

  • 120v 1ph service is required to support standard low-pressure air blower units. For larger high-pressure air compressor or international units, 1 ph or 3 ph service at 50 or 60 hz may be required.

Note: Air-powered mixers should not be used in enclosed tanks or other areas where methane or other explosive gases may build up. Some gases may explode when combined with air.
