This technology is exclusive to Kershki in Australia! Worldwide Patent
Graffiti Cleaning Machine
The incredible power and efficiency of the Graffiti Cleaning Machine has to be seen to be believed. Using negative pressure, this revolutionary technology exclusive to Kershki in Australia will revolutionise the way Australian's remove graffiti, lacquer layers and de-rust.
The Kershki Graffiti Cleaning Machine uses negative pressure to recycle finely ground walnut particles that lightly brush away layers of graffiti before your eyes. This closed circulation process means it's entirely safe for the environment and without the use of water or chemicals the Graffiti Cleaning Machine is now the safest and most effective way to clean graffiti.
The Graffiti Cleaning Machine can be used for:
Graffiti removal
Cleaning of natural stone
Rust removal
Preparation for adhesive surfaces
Layer removal / lacquer removal
Roughening up surfaces
Restoring
Benefits:
Short upgrading and stripping times
Easy to transport
Low noise level due to compressor-free operation
No chemicals or water
Closed circulation of particles ensures this product is safe for the environment
Product description
The new mobile jet system is based on a worldwide patented negative pressure jet principle. It is designed as a mobile compact device, not bigger than a customary industrial vacuum cleaner.
The unit contains three generators for negative pressure with an appropriate filter cartridge and dust separation, as well as the appropriate containers for the granulates. Also included are a jet cap, jet lance and hoses
Functioning
After switching on the negative pressure generators, a negative pressure of approx. 220 mbar is produced in the jet hood. Once the hood is set on the working surface negative pressure adheres it to the surface. By inserting the jet lance into the jet cap the cycle becomes a closed circuit. The blast medium will then suck into the jet hood through the lance at a speed of more than 420 km/h. At this rate the jet material blasts onto the surface to roughen up or clean off layers depending on the requirement. This process is easily monitored through three vision panels on the jet cap.
Immediately after the impact on the working surface, the blast medium is sucked off together with the removed particles into the machine. Within the machine the dirt particles are separated from the granulates by a filtering system. Afterwards the granulates are further processed in the second container. This cycle can be performed 60 to 80 times with the same granulates.
Due to the closed circulation and compactness, the device has a very low noise level (75 decibel) which is equivalent to a customary vacuum cleaner.
Structure and Functioning
From the funnel (1) the medium (granulates) (2) arrives at the air flow (4) over dosing equipment (3) by gravity. With a flexible suction hose (5) the blast grain is transported to the jet cap (6). At the exit of the jet lance (7) it is accelerated to a very high rate and has equally high jet energy. Protected by the jet cap the blast medium impinges on the polluted surface (8) and peels of dirt or clears away the surface quickly and dust-free. The jet process can be monitored through 3 vision panels (12). Subsequently, the mixture of dirt and jet medium is sucked off by a hose (9) into the top of the blast grain container (13). The reusable blast grain is separated and supplied to the cycle again. Ineffective fine types of dust are sucked through the dry-suction apparatus (11) into the fine dust filter (10) and can easily be disposed after termination of work. Coarse particles which are removed are kept back by the filter (14).
