Proposed is a powder removing apparatus using a screw cylinder for a gas processing facility, in which the powder removing apparatus has a structure in which a scraper is coupled to the screw cylinder that allows a piston rod to be moved forward while being rotated in one direction and to be moved backward while being rotated in a reverse direction according to a supply direction of fluid, thereby allowing the powder adhered to an inner circumferential surface of a pipeline of the gas processing facility or an inner wall surface of the gas processing facility to be easily and efficiently removed. According to an embodiment of the present disclosure, the powder removing apparatus includes the screw cylinder and a scraper.

An apparatus for driving interchangeable flexible shafts. The apparatus having a stand; a platform coupled to the stand, the platform being configured to rotate around an axis of rotation; a disconnect affixed to the platform, the disconnect being configured to connect a rotary power source to a flexible shaft; and fasteners affixed to the platform, the fasteners being configured to releasably couple a reel for the flexible shaft to the platform.

A device for driving a flexible lance for cleaning a heat exchanger duct or the like, includes a frame in which a driving mechanism is arranged for moving this flexible lance in a driving direction in the direction of an outlet opening. The driving mechanism is provided with a clamp member which can be clamped on the flexible lance and which is movable in the frame towards and away from this outlet opening. The clamp member is mounted on an endless drive element. The active part of the endless drive runs parallel to the driving direction. The drive mechanism further comprises at least one non-driven counter roller arranged opposite said clamp member. The lance is clamped between the clamp member and the counter roller.

A drain cleaning device includes a power unit and a drum assembly coupled to the power unit for rotation by the power unit. The drum assembly includes a base, a cable received in the base that is configured to be fed from the base and rotated to clean a drain, and a cover releasably coupleable to the base. The drum assembly includes a plurality of taper locks releasably coupling an outer peripheral portion of the cover and an outer peripheral portion of the base. Each of the taper locks is moveable between a locked position in which the cover is retained on the base and an unlocked position in which the cover is removable from the base. Each of the taper locks being biased toward the locked position.

A heating/ventilating/air conditioning (HVAC) air duct cleaning system with certain improvements having a system housing containing a vacuum-generating subsystem, a rotating motor with an output shaft, and a debris reservoir; a hose connection panel on the system housing positioned at an angle of approximately 45 degrees from horizontal; and a hose coupler on the hose connection panel, configured to receive a duct cleaning hose and to transfer rotational energy from the output shaft to a connection end of a rotatable cable when received into the guide portion, wherein the coupler provides coaxial alignment between the guide portion and the output shaft.

A machine comprising: a lance, the lance configured to clean insides of tubes; a guide way positioned near the tubes; a transversal drive support slidable on the guide way and configured to move the lance along the guide way towards an insertion head; a rotational drive coupled to the lance for controlling rotation of the lance; and a feeding system coupled to the lance, wherein the guide way forms at least one supporting lance channel over a length of the guide way, the at least one channel forming an enclosure from all sides for guiding the lance, whereby a part on the circumference of the enclosure is made of a flexible lip, which lip can be locally bent by deflectors travelling with the lance.
