Abstract
A method for cleaning an exhaust filter system is provided. The method includes removing ash from a first end of the exhaust particulate filter system using compressed air from the second end of the exhaust particulate filter system. The method also includes entraining particles from a second end of the exhaust particulate filter system using low pressure air. The method further includes blowing ash from the first end of the exhaust particulate filter system using compressed air from the second end of the exhaust particulate filter system. The method further includes removing the entrained particles from the second end of the exhaust particulate filter system.
