Used Equipment

Demo and used Lavina Floor Grinders, BlastPro Shot Blasters, and more equipment that works like new!

All used/demo equipment has been thoroughly inspected by Niagara Machine’s Service Team and returned to top working condition. Take a look at our line-up of Lavina used concrete grinders and polishers, BlastPro shot blasters, ride-on and walk-behind floor scrapers, DiamaPro dust collectors and other dust collection necessities, handheld grinders, and more. You can even find used burnishers, sweepers & autoscrubbers, scarifiers & shavers, concrete saws, and other surface prep equipment! If you don’t mind a scratch or a dent here and there you can get a bargain! While the look of a unit may not be perfect in appearance it will not affect the equipment's performance. 

Our demo/used concrete flooring equipment comes complete with all the proper accessories. If an original part is worn out, such as a filter on a concrete dust vacuum, Niagara’s Service Team will have replaced it before it hits our used equipment list.

First come, first served!

Unfortunately, we don’t have a limitless supply of used equipment. Once it’s sold, it’s gone. Sometimes, an item may have been sold out before our website has had a chance to get updated. We apologize if this happens to you. If it does we work with you to find another suitable option.

Call 800-622-2048 for a complete list and pricing of available used concrete grinders, concrete floor scrapers, concrete shot blasters, dust collection systems and more!
