A surgical drape or sheath system, apparatus and method is shown for reducing or eliminating contamination. The surgical drape or sheath system, apparatus and method comprise at least one body that is mounted on or in the vacuum tube while a generally tubular drape or sheath is draped or positioned over at least a portion of the vacuum tube so that it can be grasped by a user. The surgical drape or sheath system, apparatus and method may be disposable or may be provided with reusable components or components that can be replaced.

Foldable filter bags, filter bag support assemblies, and filter bag assemblies are described herein. The foldable filter bags, filter bag support assemblies, and filter bag assemblies may be used in air filter systems to remove particulate matter from air or other gases. Methods of using the air filter systems and methods of assembling the filter bag assemblies are also described.

A pocket filter comprising a plurality of filter pockets, a frame holding the filter pockets, and at least one clamping strip fixing filter layers of two neighboring filter pockets. A profile of the clamping strip is designed in one piece and has a first section and a second section that are movably connected to one another, a T-shaped locking element is formed on the first section, and the T-shaped locking element has a base and a cross-piece extending substantially perpendicularly to the base. A proximal hook-shaped locking element and a distal hook-shaped locking element are formed on the second section, between which the T-shaped locking element is arranged and which engage behind the cross-piece when the clamping strip is in a locked state in which the filter layers of the two neighboring filter pockets are clamped in the clamping strip.

A vacuum cleaner has a vacuum cleaner bag having two layers made of filter material, which are joined together on at least three sides to form an inner chamber. An inflow opening is formed on a fourth side between the two layers, at least in regions, into which a connector for connecting to a vacuum cleaner can be inserted.

The pocket channel frame provides a means for attaching the distal ends of a pocket frame without the need of any tools. The pocket channel frame is formed from a longitudinal member having an elongated “C” shaped cross section. One end comprises is a flared out female end with a rectangular slot or 5 hole in it. The opposing distal end of the longitudinal having a C shaped cross section is swaged down into a projecting male end including a lance punched in the web. When the male end is swaged, an edge is created in the transition area from male to female which acts as a stop means for cooperatively engaging the female receiving distal end and sets the length of a short side of the pocket channel frame. During assembly, the lance snaps into the hole cooperatively engaging the slot on the 10 female side preventing the channel frame from coming back apart.

A backpack dust collector includes a housing. The housing includes: a suction port; a dust collecting chamber connected to the suction port and configured to accommodate a dust collecting bag; a motor chamber connected to the dust collecting chamber and accommodating a fan and a motor; an exhaust port through which air from the motor chamber is discharged; first and second battery openings; and first and second battery receiving portions respectively corresponding to the first and second battery openings. At least part of the first battery opening is formed on a left side surface of the housing, and at least part of the second battery opening is formed on a right side surface of the housing.
