How Pulsair Works: Frequently Asked Questions


How can one air bubble mix 10,000 gallons?

It can't. Additional accumulator plates are positioned in concentric circles around the central plate and pulsed alternately.


What about air entrainment?

When properly adjusted, the large Pulsair bubbles will not add entrained air. In fact, Pulsair will actually remove entrained air unless designed to do otherwise.


How often do you change air filters?

There is no need to change filters as long as they are kept free of emulsions, contaminates and any accumulation of water. The automatic filter drains should be checked periodically.


What keeps liquid from flying up the air pipe when it's not pressured?

The amount of back pressure in the tank is calculated by the depth and viscosity of the liquid in the tank. A check valve is
set to prevent back flow.


Are Pulsairs safe to operate in hazardous locations?

Since Pulsairs operate on pneumatics or very low voltage, there is little chance of electrical arcing. As a precaution, units
can be enclosed in an explosion proof enclosure or by placing electrical components outside of hazardous locations.


What is the "life expectancy" of a Pulsair installation?

There are no moving parts inside a Pulsair controlled tank, thus there are no seals, gears, bearings, shafts, propellers or
impellers, etc., greatly reducing the likelihood of equipment failure. The only moving parts are the logic relays inside the
controller and injection valves. These parts are rated at 100 million cycles, or about ten years of continuous, 24
hour operation.


How many tanks can your programmable controller handle at one time?

There is practically no limit, It simply defends on the member of programmable chips you can include in the enclosure.


Can you do anaerobic treatment of wastewater?

Pulsair can be configured to operate either as an aerobic or anaerobic water treatment system.


Will increased air pulse or pressure increase mixing efficiency?

As a matter of fact, no. Tests have shown that maintaining a minimum amount of pressure and increasing the time
between pulses produces maximum efficiency with less energy expense.
