COTON AQUATEST 22 tyre pressure testing machine - front view

The COTON AQUATEST 22 tyre pressure testing machine is used to quickly and efficiently diagnose tyre defects such as bulges, bubbles, punctures, cuts and all kinds of damage to the cords, wires and beads. With its help, a skilled operator can inspect a tyre in just over a minute, making it indispensable for tyre warehouses, tyre fitters and retreaders.

This model meets the expectations of the most demanding customers in the tyre industry, as the use of a rising water tray allows the detection of even the smallest pinholes in the tyre. Efficient operation is ensured here by a motor for turning the tyre to be inspected, which is activated by a foot switch (pedal) or a switch on the side of the machine (both options available). What’s more, a robust guard protects the operator from the consequences of an unexpected burst of the inflated tyre.

The machine is suitable for inspecting tyres dismounted from 13-22 inch rims (car, jeep or light truck), and a set of locking latches (pawls) allows tyres of any width to be fitted to the machine. Three pairs of discs are available in the kit:

  • Pair 1: sizes 13-16 inches,
  • Pair 2: sizes 17-20 inches,
  • Pair 3: sizes 21 and 22 inches.

In order to start working on this tyre inspector, it needs to be connected to an air compressor of average capacity (main power supply) and an electrical socket (motor power supply). The control itself, on the other hand, is convenient and intuitive and is carried out by means of levers located on both sides of the machine.
