Blower Heat Reactivated air dryer Continuous air supply:Special design is made to ensure the compressed air is continuous when the tower is switching. Meanwhile, it can avoid the air flow's momentary impact to the desiccan. There are small support balls at the bottom of the towers and the desiccant is filled in by special way. And a stainless halftone is fixed at the top of the tower as a press. In this way, the tunnel effect can be avoided and the mutual friction of the desiccant can be prevented.
