Ametek 116765 Lamb Central Vacuum Motor

I was concerned I would not be able to switch out this central vacuum motor. It ended up being a lot easier than expected. There were 3 spring nuts to hold down the motor and 2 wired to connect. Works great!

This vacuum blower *really* moves the air. The three stages really allow it to produce a great vacuum - I measured nearly 10" mercury (that's more than 125 inches water column) with a blocked inlet, which is the mode I'm using it in (for a special type of vacuum press). Because of my application, I needed the separate bypass cooling air that this blower uses. If you build your own enclosure, be aware that it's essential to significantly separate the cooling fan inlet (on the top of the motor) from the discharge (all around the base of the motor). Even when the inlet is blocked, so it's theoretically not compressing any air, it still consumes nearly a full kilowatt (~960 watts, according to my clamp-on ammeter), and all of that ends up as heat, of course. I actually had to add a close-fitting baffle to keep the exhaust air from recirculating back to the inlet. Be aware that all that energetic air thrashing, as well as the compression (Boyle's gas law, etc.), really causes the process exhaust temperature to rise, too. I measured nearly 200 degrees there, so plan your discharge accordingly. With these caveats in mind, if you need a blower that moves a lot of air, and has quite a high head pressure (I didn't measure the stopped exhaust, but I'd expect around 5 PSI or so), this is an excellent choice, especially for the price.

Direct replacment for my Electrolux in house vacuum. Fired right up after replacing the motor and we put many hours on it without issues.

The motor was ordered to fit a 20 year old Beam Central Vacuum. The motor fit as it should. Did need a couple of small adjustments; original motor had a screw hole to attach the muffler to the motor, this one did not and we had to drill for new one; the second is that the motor did not come with wire lugs, did have to do a small bit of soldering to get the right ends to connect. Not of it was a big deal but it was not just swap. Motor works like it should and vacuum is running fine. Good deal on Amazon. Would purchase again.

My 20 year old Hoover Hush series central vacuum unit quit on me. The relay part still works because I heard a click when I press the trigger as I normally do to vacuum. As usual I immediately got to YouTube and learned about the symptoms and diagnosis for the cause of the problem. I took out the motor after taking a few photos of the wiring and found the model number. Also as usual I got to Amazon and ordered the motor that came two days later. I installed and walla it turned on as new!

Used this to replace the motor on my CentralVac which burnt from running for too long. Replacement was pretty simple and just works. Seems it is a little quieter than the old one I replaced it which is an added plus

This is a multi stage motor. It should have more suction.

Fit my 20 year old Easy-Flow central vac perfectly. This looked identical to the original part. It even came with a new gasket. The instruction were complete. Shipping speed was as expected. I need to supply a couple of wire nuts to complete the repair. I took about an hour and a half to complete the repair. I took my time on this. I could probably do it again in about half hour to 45 minutes.
