K 6000 is our fixed-type foam spraying machine with a 60-liter capacity and a chrome body. Generally, our machines are preferred to operate with 1 TL coins. The working principle with coins is as follows: When a coin of the same denomination as the machine's mechanism is inserted into the coin slot, the machine detects it and starts operating. For example, if the mechanism is designed for 1 TL coins, the foam spraying machine will work with 1 TL coins. Due to the widespread use of this system, these coin-operated foam spraying machines are commonly known as car wash machines that operate with 1 TL coins. In recent times, besides gas stations, car wash companies have started providing services to their customers by setting up separate stations with these machines. The K 6000 foam spraying machine is a 1 TL coin-operated car foam machine with a stainless steel chrome body. This ensures that it remains rust-free and maintains its attractive appearance for many years. Additionally, it has a counterfeit money recognition feature.
