The CoachVac is off ProTeam's current parts-list index, which is exactly why this page matters. Part 100420 is the OEM motor and fan assembly for the 220-volt CoachVac, supplied with crimps, and it is the difference between keeping a working backpack on the route and retiring a machine because a motor gave out.
ProTeam's own CoachVac and Super CoachVac parts document lists it as 100420, Motor/Fan 220V with crimps, for the Coach Vac, and it appears in third-party parts catalogs under the same description. Of the 220-volt motor assemblies, this one has the clearest documentation trail.
Built for
- Replacing a failed or fading motor in a 220-volt CoachVac, using the number ProTeam assigned to that machine rather than a near-match.
- Stocking a fleet spare for international CoachVac units still in daily service where a downed unit costs a shift.
- Full refurbishment of an older CoachVac alongside filters, seals and mounting hardware, bringing the whole machine back at once.
What a 5.7-inch 2-stage thru-flow motor is
The 5.7-inch figure is the fan and body diameter, the standard mounting dimension for commercial vacuum motors, not a power rating. Two-stage means two fans are stacked in series, with the first pressurizing air into the second, which raises sealed suction well above a single-stage motor at similar wattage. Through-flow, sometimes written thru-flow or flow-through, means the working airstream passes through the motor and cools the armature and brushes on its way out.
That cooling method is why through-flow motors are lighter and more compact for a given airflow, and it is also the one rule you cannot break: they are rated for clean, dry, filtered air only. Never use a through-flow motor for wet pickup, and never run one with neglected filters. Filter neglect is the leading cause of through-flow motor failure, because the motor sits directly downstream of the debris path.
Why a 220-volt version exists
These motors serve machines sold outside North America, where mains supply is typically 220 to 240 volts at 50 Hz, as well as export builds of North American machines. A 220-volt motor is not a more powerful version of the 120-volt motor; it is the same fan geometry rewound for double the voltage at roughly half the current. If you are converting or repairing an export machine, remember that the ancillaries change too, including the switch cord assembly.
How long these motors last, and how they tell you
Repair-trade figures put the original carbon brush set at roughly 700 to 900 hours, with a fresh set of brushes buying about 400 more, and a practical ceiling near 1,200 hours before bearings or the armature become the limiting factor. Brushes are considered finished when worn shorter than 3/16 inch from a new length of about 3/4 inch.
A motor on its way out announces itself: suction that keeps falling after a bag change, a filter clean and a clog check; a rising whine, squeal or grinding from the bearings; visible sparking or a heavy arcing glow at the commutator; a burnt electrical smell; carbon dust collecting in the filter chamber; and intermittent cut-outs. Two or more of those together, with filters and clogs ruled out, is the standard call to replace the motor.

A note on motor make
Both Domel and Ametek motors shipped in these machines across the production run, and ProTeam lists a separate carbon brush set for each, part 105697 for Domel and part 100424 for Ametek. ProTeam's parts document annotates this line as a Domel motor. Rather than assert a manufacturer we cannot confirm for your particular unit, we will say the useful thing: read the nameplate on the motor in your machine before you order brushes or commutator parts.

Frequently asked questions
Does this fit the Super CoachVac?
ProTeam's parts list assigns 100420 to the CoachVac and 100324 to the Super CoachVac. Confirm which machine you have before ordering, because the two are not interchangeable.
What is the 120-volt equivalent?
ProTeam 105720, Motor/Fan 120V with crimps for the CoachVac.
Do I need anything else to install it?
The crimps are included. Parts commonly replaced at the same time are the motor compression ring with screws, part 100335, the motor ground and wire clamp set, part 100379, the motor mounting system set, part 100368, and the tetraseal, part 100014.
Which carbon brush set matches?
ProTeam lists two for the CoachVac, part 105697 for Domel and part 100424 for Ametek. Identify the motor from its nameplate before ordering brushes.
Is the CoachVac still supported?
The model is off ProTeam's current parts-list index, so treat OEM stock as finite and confirm availability at order time.
Does it include the power cord or switch?
No. The 220-volt switch cord assembly is a separate part, ProTeam 101717.
