This is the complete zippered outer bag assembly for the Koblenz U-75 commercial upright, the FnG style unit that carries the disposable bag and forms the machine back. On a commercial upright the outer bag is a wear part in the same way a belt is. It gets caught on door frames and desk corners, the zipper takes hundreds of cycles a year as the crew changes disposable bags, and eventually the fabric splits or the zipper fails. Once it does, the machine leaks dust from the seam every time it runs, which defeats the filtration the disposable bag was doing.
Replacing the assembly rather than patching it puts the vacuum back into service properly. For a building services contractor or an in-house housekeeping department, this is the difference between retiring a perfectly good machine and returning it to the route the same day. The U-75 is a durable 7 amp commercial upright that outlives several outer bags over its life, so keeping the wear parts available is normally the cheaper path by a wide margin.

Frequently asked questions
Is this the disposable bag or the outer bag?
This is the outer zippered bag assembly, the fabric housing that the disposable filter bag sits inside. It is a durable component that is replaced when it tears or the zipper fails, not a consumable you change with every fill.
Why replace the outer bag instead of taping the tear?
A split outer bag lets fine dust escape at the seam, so the machine puts material back into the room it just cleaned. Tape traps some of it briefly but fails as soon as the bag flexes. On a machine used in occupied buildings the leak is a filtration problem, not a cosmetic one.
Will this fit other Koblenz uprights?
It is made for the U-75 in the FnG style. Koblenz used different bag assemblies across its commercial upright line, so check your model badge before ordering. Our team can confirm fitment against your machine model and serial number.
How long should an outer bag last?
On a normal janitorial route several years is typical, but it depends far more on how the machine is handled than on hours. Bags most often fail from snagging on door frames and furniture, and from zipper wear as crews change disposable bags, rather than from age.
Discount Cleaning Products is an authorized dealer for the brands we carry, and we stock genuine and OEM-equivalent replacement parts alongside the machines they belong to. Our US-based team can confirm fitment against your model and serial number before you order, so the part that arrives is the part your machine actually takes.
