The SubAir aeration and moisture removal system promotes healthier, stronger playing surfaces through moisture content management, subsurface aeration, and root zone temperature control. As a result, SubAir helps provide an optimal growing environment for any playing surface – increasing playability and producing a more enjoyable experience for players and spectators.

SubAir Sport Features

SubAir Sport is automated based on data received from the field through the AirWave monitoring and control system. AirWave receives and reports soil data (salinity, moisture, and temperature) via wireless sensors placed at critical positions within the soil profile throughout the field. The data then prompts the SubAir Sport to perform according to the levels and parameters set by the turf manager. Every operation of the SubAir Sport is fully automated and accessible through any internet connection or wireless device.

“The ability to control the environment is obviously a key defense in battling disease and pest issues, and my SubAir system makes this possible. In three years at BMO Field there has not been a need for the use of pesticides, partly attribute that to the SubAir system. With more and more regulations being places on the use of pesticides, SubAir seems likely to be one key to success in the future of professional turfgrass.”

Robert Heggie, Head Groundskeeper, BMO Field and The KIA Training Grounds, Academy Toronto Football Club

“If I did not have SubAir it would have been much more challenging because I would not have been able to monitor the exact moisture content in the soil and instead would have had to do more guessing.”

Hans Niska, Director of Facility Management, Rio Tinto Stadium, REAL Salt Lake

SubAir Sport Installation

Prior to construction, SubAir project managers work with architects, engineers, contractors, and stadium staff to ensure the drainage system is compatible and pipe elevations are suitable for maximum SubAir operation, all building specifications are met, and all necessary utilities are arranged. SubAir can provide a turnkey operation or utilize existing facility contractors or stadium staff already involved with the project to complete the installation. A SubAir representative will be present during installation to instruct and supervise all aspects of installation. In addition, a SubAir representative will commission each project by performing field tests and training sessions for members of the staff.

Retrofitting a stadium or field with a SubAir Sport system requires accurate drawings of the drainage system and an available storage area to house the system. SubAir project managers are available for planning and during the installation process.

“I think the return on investment is the opportunity to protect a baseball game from losing the gate and an opportunity to host more events because we can recover quicker and not affect the baseball field.”

SubAir Sport Operation

SubAir Sport system connects to the main drainage collector and moves air through the drainage network utilizing the perforated holes in the pipe to access the soil profile. The main drain collector is intercepted by a SubAir air line. The air line then connects to the SubAir air-water separator. An air-water separator is designed and installed between the field and the SubAir to remove any water from the system.

Activating the vacuum mode, allows the turf manager to remove standing water in a short amount of time, remove non-capillary water from the soil profile, and introduce fresh air into the root zone. The vacuum mode is used to remove standing water during games or other events. As a daily practice, the vacuum mode fosters a healthier growing medium for the plant’s roots, helping to establish stronger roots and stronger turf.

Activating the pressure mode enables the turf manager to inject fresh air into the soil profile during stressful events or extreme temperatures, hot or cold. Turf managers who use the SubAir Sport system utilize the pressure mode to constantly inject fresh air into the profile during concerts or other events requiring temporary covering of the turf surface. Other SubAir Sport System owners use the pressure mode to expedite the activity of specified radiant heating systems (Hydronics). The pressure mode is especially beneficial to those turf managers who have heating via forced heated air (furnace).
