NO FILTER ! !
What makes S&B Particle Separator helmet pumps so unique? They DON'T use a filter. Without a filter to clog, you can start and end your race with the same great airflow. Based on technology used by the military, S&B's helmet air pumper system removes 99.36% of the dust without a filter to provide you with consistent airflow throughout your race.The blower has a variable speed knob on it with two fans. The primary fan draws air into the blower, while the bottom secondary fan blows all the silt, sand and dust downward out of the unit.
