Mitas a.s. has introduced the AirCell, an inner tire that enables the inflation of large agricultural tires by +/- 1 bar (from 0.8 bar to 1.8 bar) within just half a minute. Mitas reported this is more than 10 times faster than the current method of inflation.
Mitas AirCell is located on the rim inside the tire and occupies about 30 percent of the volume of the tire. The AirCell has been designed for the Mitas 710/75 R42 SFT, and other sizes will follow. AirCell is inflated continuously to a maximum of 8 bar during the tires use, Mitas said, releasing some pressure on demand, which enables a rapid increase of pressure into the agricultural tire itself adjusting the pressure in seconds rather than minutes. Mitas AirCell will be available for the Fendt 900 Vario equipped with Mitas 710/75 R42 SFT starting in Nov. 2016. Mitas said this pressure inflation system is marketed as VarioGrip Pro received a DLG Agritechnica Gold Medal.
Not only does the AirCell enable rapid tire inflation, Mitas said, but it helps to release the pressure just as fast again as the volume of the outer tire is reduced by up to 30 percent. Mitas said the AirCell is not in contact with the tire itself, and so it does not create any additional friction or heating. Additionally, Mitas AirCell is made from sturdy rubberized materials that retain its shape even when inflated to high pressures so the volume of the outer tire does not depend on the inflation of AirCell, Mitas claimed.
Mitas AirCell will be available for Mitas 710/75 R42 SFT, the Mitas 710/70 R42 SFT and additional sizes too. Mitas manufactures AirCell in the Czech Republic.
