Panasonic claims its CS18GKF, CS-C24GKF and CS-C28GKF air-conditioners use an E-ion purification system that detects and collects dirt in the air. Tougher hygiene regulations are forcing processors to upgrade their equipment to ensure compliance. Hazard analysis and critical control points (HACCP) require processors to examine the risks that exist in their operations that include susceptibility to airborne bacterial and viral organisms that can lead to contamination. Preventing airborne pathogens spreading within working environments also helps to prevent illness among employees. Abby Thomas, a product manager of air-conditioners at Panasonic explained how the air conditioner works. "Whenever the system's sensor detects dirt concentration above the allowable level, the E-ion Air Purification System discharges active e-ions that neutralize airborne bacteria and mould," she said. "The E-ions also catch negatively-charged dust particles and bring them back to the system's positively-charged mega filter in a boomerang-like mechanism." As well as eliminating potentially harmful dust particles in the air by releasing around three trillion active E-ions, the air purifying system also neutralises various air pollutants such as cooking smoke and odors, the manufacturer claims. Panasonic said the Blue Fin condenser technology has a life span three times longer than other condensers with low electricity consumption. The condenser is covered with an anti-rust coating that withstands damage from exposure to corrosive factors such as salty air, wind and dust.
