SPORT ejectors

TENNIS
The air ejectors serving TENNIS are no mechanical moving
parts devices powered by an external high pressure & low
flow blowers or portable compressed air tank/bottle. The main
applications are at the tennis robot and tennis ball
collector. We are studying the possibility to have air drone
that shoot tennis ball from any positions down and up, at
natural level of human. The movement of the flying tennis
robot needs to be as fast as the real human. (photo

Usual ejector types for this application are:

ARENA
The air ejectors serving ARENAS are no mechanical moving
parts devices powered by an external high pressure & low
flow blowers or mobile screw compressed air. The main
applications are at the air movements near the grass level in
order to dry the grass area for arena maintenance and also to
the ventilation during the competition having full capacity of
humans by creating smart air flow that get fresh oxygen in any
part of the arena. (photo www.bayer04.de)
Usual ejector types for this application are:

PARACHUTING
The air ejectors serving PARACHUTING domain are no
mechanical moving parts devices powered by an external high
pressure & low flow blowers or mobile screw compressed
air. The main applications are at the vertical wind tunnels
and indoor skydiving for training and fun. Wind tunnel
velocities are between 27-35 m/s and efficiency will be higher
when the tunnel has closed loop. The tunnel is safer having no
vibration because the system has no rotor/blades. (photo
