ProTeam Air Duct Upper - 15...
$14.99
Product details
Dirt-laden air travels up through a sealed passage inside ProTeam's ProForce 1500 HEPA upright before reaching the bag, and this upper section of that passage is what part 104578 replaces. A crack anywhere along the run opens a leak in the middle of the airflow path, and suction lost that way does not return until the duct itself is fixed.
Weak pickup on a machine with a fresh bag, a clean filter, and a clear hose points to damaged ductwork more often than most owners expect, since a split duct mimics a clogged filter closely enough from the operator's seat that the two are easy to confuse. The difference only becomes obvious once the duct is exposed and the crack is visible, which is why this part gets overlooked in favor of swapping filters and bags that were never actually the problem.
Molded to the original equipment dimensions, this replacement seats precisely against the parts it mates to and rebuilds the tight seal the machine had when new, holding up under the vibration and constant handling that comes with daily commercial work. A crew running a machine five days a week puts more cumulative flex on a duct than a home user does in years, so ductwork on that duty cycle sees far more stress than home use ever applies.
Reaching the upper duct means opening up the machine's upper body, so keep the vacuum unplugged for the entire job and follow your model's service diagram for which panels come off first. Before fitting the new piece, check the surfaces it seals against for built-up debris or a worn gasket, since even a correctly fitted duct will still leak if what it presses against is not clean and true.
