ABSTRACT:
Installation and maintenance equipment to tension a fabric sleeve filter supported from a bag support frame in a baghouse by a retainer rod and a tensioning spring. A pneumatic tool is configured to be removably coupled to the retainer rod while compressing the tensioning spring to pull taut the fabric sleeve. A flow control valve regulates the speed at which the spring is compressed and a pressure regulator determines the force applied to the spring.
