With a normal hand or floor pump it’s not possible or at least very difficult to pump up a tubeless tyre. The Chamber Tubeless Floor from Blackburn makes it possible because it has an additional cylinder that can be filled with air, so that it can be released into the tyre at lightning speed by operating a lever. This ensures that the shell is perfectly pressed into the rim. That's how fast it can go.
In addition to the tubeless function, the Chamber Tubeless Floor can also be used as a normal floor pump. You can read how high the pressure is in the tyre or in the large cylinder from the manometer.
