The invention relates to a fabric filter system, having a first fabric filtering device in the form of elongated tubular fabric bag; a first gas tank for providing compressed gas; a first pulsing gas duct fluidly connected between the first fabric filtering device and the first gas tank through a first pulsing valve for cleaning the first fabric filtering device. The fabric filter system further includes a second gas tank for providing compressed gas. The second gas tank is fluidly connected with the first gas tank through a control valve. The first pulsing valve is opened to introduce the compressed gas into the first filtering device for cleaning when the control valve remains open. The control valve is closed after a predetermined time. A method for cleaning the fabric filter system is disclosed.
