The Alpha PVA Quick Change System is a low speed version of the original PVA system and is designed for use on an aluminum snail-lock backer plate specifically developed for low speed polishing tools such as the AWP-158 and the AIR-658. Alpha PVA Quick Change will work on all of the same applications as the PVA with the same excellence and quality.

Marble shops， tile installers or anyone else that already has access to a low speed polishing tool will find that the Alpha PVA Quick Change system will speed up their productivity. The aluminum backer plate is attached to the polishing tool and each of the pads has a snail lock adapter. The adapter simply fits into place and locks on with a twisting motion. To remove the pads simply untwist and remove， then replace with the next grit. This Quick Change process saves time， increases productivity and is an Alpha exclusive.
