The use of a venturi to mix the air and water has the highest oxygen transfer rate of any device.
Additionally the water and air are mixed under pressure through at least 10 feet of pipe.
The turbulent flow and extended air/water contact time create an excellent mixing process that
simulates deeper water. The intake manifold is on or near the bottom of the water body with the
discharge at the top of the water column, creating a bottom to top mixing effect plus the horizontal circulation of the discharge nozzle. The inducted air travels the length of the discharge pipe and is exhausted through the PAM Cannon.

The final result is vertical and horizontal water movement with the constant introduction of air into the water column at a very low electrical cost of less than $1.25 per 24 hour operating period
(based on 12 cents per KWH).

You can purchase and install this system for 1/3 the price of a standard 1 HP diffuser system and operate it for 2/3 less energy. Installation is easy and does not require any special tools or skills. The pump plugs in to a standard household electrical outlet.

THESE NUMBERS ONLY REPRESENT ACTUAL WATER PUMPED. WE DO NOT CONSIDER AFFECTED GPM SINCE IT IS NOT ACCURATLY MEASURABLE. FINE BUBBLE DIFFUSERS AND OTHER "PUMPED AIR" EQUIPMENT DO NOT PUMP WATER, YET THE CLAIMS ARE USUALLY IN THE MILLIONS OF GALLONS. THIS IS AN IMPORTANT FACTOR WHEN COMPARING EQUIPMENT. ECO POND RESCUE IS THE ONLY MANUFACTURER THAT CAN PROVE ACTUAL WATER CIRCULATED.

To Refute Typical Bubble Diffuser Claims

In our research there are no exact formulas for “induced water flow” or “affected water flow” from any engineering firm we’ve contacted. Frankly, we would like to make the same claims however we choose not to because it is not a directly measureable or quantifiable specification.

The specification requirement to move 10,000 gallons of water (83,000 lbs) every minute with less than ½ horsepower (240 watts) is a rather sensational specification. One engineer suggested that you could move all of Lake Mary by throwing in a brick with which you could argue the eventual inertia will effect some movement in every gallon of water as an example. However, that does not translate well in practice.

We will provide you with the actual water pumped specifications with which you can draw your own conclusion regarding inertial (induced) water flow.

 

These numbers do not include the “affected GPM” which represents the water that is moved by the kinetic energy (energy in motion) created by the intake and discharge of the water. This is simply the amount of water/air moved by the pumping system.

Typical 1 hp diffuser systems use between 9 and 12 amps of electricity delivering 4 to 6 CFM. The circulation from these types of systems are from the rising bubbles (passive movement). Therefore in shallow lakes (less than 8ft) the circulation is often much less than listed.

With less electrical demand, high measurable water circulation and the excellent transfer rate of a venturi system you can now afford to aerate and circulate around the clock.

The system comes with all fittings, pump, pump house, venturi, installation instructions and connections. Depending on the installation requirements additional, commercially available, PVC pipe must be purchased.
