WORKING PRINCIPLE
Our air showers are easy to operate and are quite economical. They are operational with a simple plug-in to the power source and require minimal maintenance. Our air shower tunnel uses a combination of basic floor plan styles with individual air shower units coupled together side by side or end to end to create a tunnel configuration for the passage of large groups of personnel. They are
The air circulating within the air shower tunnel passes through the filter assembly, comprising of pre-filters and HEPA filters, for efficient removal of dust and contaminating particles within the equipment. The clean air is then passed through the nozzles at a high velocity to create pressurized air streams, capable of providing enough scrubbing action for the removal of particulate
