Our new Mitchell Golf Club Repair Vac houses a high volume, high pressure air movement system of 1200cf per minute of down-draft vacuum that will eliminate almost all the shaft dust you create. Dust is pulled through a filtration system of two specially coated filters that are included. These filters will capture dust particulates as small as 8-micron in size. These special filters are available for replacement and are required to ensure the vacuum pressure needed to work sufficiently. Do not use other filters as they will not work properly.
