Nozzle with a pressure gauge and 2 valves of a smooth press, 1 with a check valve, 2 without a valve

The model is equipped with a manometer, which allows you to control the balance of helium in a cylinder, a pressure valve with a conical tip to fill with helium of latex balls of any size, a cutting for the tape and a device for fixing the tape with a clamp. There is also a gearbox for inflating foil balls. Helia feed automatically stops when the ball is inflated to the desired size. This guarantees the maximum time of the flight of the ball and excludes the possibility of its break.
