A SubAir Elite vault, housing the blower that provides both vacuum and pressure mode, is connected to the piping network.

A Distributed Separator is connected to the green’s drainage network. This patented assembly separates the air from the water so that the air flows to the SubAir vault and the water drains to the outfall. A Dual Valve is used on the end of each outfall to create an air lock. This directs the air through the soil profile so it does not escape through an open ended pipe.

SubAir’s control system is housed in a standard irrigation satellite and is located away from the green. Once the installation is complete, only the air intake/exhaust (9″ x 9″) and vault inspection port are visible. Installation typically takes one day per unit and can be accomplished with minimal disruption of play.

The SubAir system applies a vacuum within the subsoil drainage pipe network to increase the rate at which water is moved from the surface and through the soil profile. The management of subsoil moisture also helps with temperature moderation in the entire soil profile.

SubAir also applies pressure to force air from the subsoil pipes through the soil profile. This patented technology creates air movement that provides aeration while moderating temperature in the root zone.

The best location for the SubAir vault is at the high end of the green. The elevation forces the air to flow uphill to the SubAir unit and allows gravity to drain water down to the outfall.

In the vacuum mode, air and water are moved downward through the soil into the drainage pipes. Once the air and water enter the pipe, gravity moves the water down to the outfall and the SubAir moves the air to the back of the green and out through the SubAir exhaust. To install SubAir, the course will need USGA specification greens or California style greens. No matter which SubAir product is chosen, the SubAir Operation Package is required to connect the drainage system to SubAir. These components can be installed during construction, during renovation projects, or while the course is open for play. Installation does not disrupt play and all the work is performed off the green so it will not interfere with golfers on the course.
