Cracked housings are a different category of repair from worn motors and loaded filters. Nothing electrical has failed - the machine was dropped, hit by a door, or run into one too many loading-dock edges - but the tank no longer holds a seal, and without a seal there is no suction to speak of. ProTeam part 103825 is the gray vacuum tank housing for the CX400 canister vacuum, and it is what puts a structurally damaged but mechanically healthy machine back to work.
The CX400, CX420 and CX440 are ProTeam commercial canister vacuums - wheeled cylinder machines with a hose, wand and floor tool rather than a backpack harness. They are a legacy line: ProTeam has moved on, several CX consumables are listed as discontinued, and the current authorized ProTeam parts catalog no longer carries a CX model page. That is exactly why replacement parts for them are worth stocking. A CX canister with a sound tank and good filtration is a machine that owes nothing, and a single component swap keeps it earning.
Built for
- Replacing a cracked, split or impact-damaged tank housing on a CX400
- Restoring the airtight seal that suction depends on after physical damage
- Vacuum repair shops performing structural repairs rather than routine wear service
- Keeping a machine with a healthy motor and good filtration out of the scrap pile
Housing damage is a suction problem
It is worth being explicit about this, because a cracked tank often gets misdiagnosed as a weak motor. A canister vacuum works by maintaining a pressure difference inside a sealed body. Any crack, split seam or warped mating surface bleeds air in ahead of the filter, and the machine loses lift everywhere - at the floor tool, at the hose, at the wand. The motor may be running perfectly and the airflow at the nozzle will still be poor. If you have already replaced filters and bags and the machine still will not pull, inspect the housing and the lid seal before you order a motor.
Fitment note - read before ordering
We could not locate a published ProTeam parts manual for the CX400 confirming part 103825 by diagram reference. ProTeam did color-code CX housing and trim components by sub-model, which is documented - CX420 trim is red, CX440 trim is black and silver - and the gray designation on this part is consistent with that practice for the CX400. But consistent is not confirmed. We also cannot confirm from published sources whether this part is the complete tank or an outer shell only, or whether lid and latch hardware are included. Verify against your machine parts diagram, or send us the model and serial and we will work through it with you before you order.

Frequently asked questions
Does a cracked housing really affect suction?
Yes, and more than most people expect. A canister vacuum relies on a sealed body to hold a pressure difference. A crack or split seam admits air ahead of the filter and the machine loses lift at the nozzle even with a perfectly healthy motor.
Is this the whole tank or just the outer shell?
The manufacturer does not publish that detail for this part, so we will not state it as fact. Contact us with your model and serial before ordering and we will confirm what you need.
How do I tell a housing problem from a motor problem?
Replace or clear the bag and filters first. If airflow at the hose is still weak and the motor sounds normal and runs at full speed, look for cracks, a warped lid seat, a damaged gasket or a latch that no longer pulls the lid down tight.
Will a CX420 or CX440 housing fit my CX400?
Treat that as unlikely and unverified. ProTeam color-coded and part-numbered housing components by CX sub-model, so match the part to your own machine.
Is it worth replacing a housing rather than the machine?
If the motor, cord and filtration are in good condition, yes - the housing is a fraction of the cost of a canister vacuum. If the machine is also due a motor, weigh the total against replacement, remembering the CX line is legacy.
Discount Cleaning Products is an authorized dealer for the brands we sell, so the parts on this page are genuine manufacturer components rather than look-alike substitutes. Our support is US based, and if you are unsure which part your machine takes, send us the model and serial number and we will work through the parts diagram with you before you order. We would rather spend five minutes getting the fitment right than have you return the wrong part.
