Rotary Scarifiers

Desco’s Mini-Flushplate and FX Flushplate systems were designed as an innovative solution for applications previously requiring multiple tools. The Desco Flushplate enables the operator to make up a number of tools by simply changing out the abrasive hub.  Whether removing rust and corrosion, heavy coatings or providing a mechanical shot blast profile, the Desco Flushplate Systems are capable of tackling all these applications with a simple head change. Desco Flushplate Systems also include engineering controls that enable safe use in the most hazardous environments, including lead abatement and even radioactive decontamination.

 

Mini-Flushplate

The Mini-Flushplate, with its multiple interchangeable abrasive heads, is one of the most versatile tool systems available today.  Employing the 3M Roto Peen hub, the Mini-Flushplate performs like a hand-held controlled shot blast machine capable of achieving SSPC Sp.11 cleanliness and is NAVSEA approved.  The hammer hub, when used, performs like a high speed needlegun. The cutter hub is the most aggressive and is capable of removing non-skid and even scarifying concrete.

Interchangeable Hubs

Hub Type

Description

Cutters are used to remove heavy coatings including epoxy and elastomeric type coatings, mastic removal, non-skid removal, as well as concrete scarification.  Two types of cutter hubs are available:
1) Welded – when cutters wear out the hub is discarded.
2) Reloadable – when cutters wear out, the hub is reloaded.  A reload kit is available which includes cutters and other wear parts.

Roto-Hammers are very effective in removing fracturable coatings. Due to their design, they are also ideal for removing coatings from irregular surfaces or surfaces with holes or protruding objects such as nuts, bolts, welds and tie downs.  Due to the Roto-Hammer design, they perform much like a needlegun in terms of both profile and versatility.  Hammers will step over obstacles like bolt heads and step into depressions, in the same manner as the needles of a needlegun.

Roto-Peen Flaps are used to remove fracturable coating up to a 20 mil thickness.  Roto-Peen was designed to provide a shotblast type profile and meets the 1 to 3 mil profile specified by SSPC SP-11. Roto Peen is approved for use on steel, aluminum and concrete substrates.  Roto Peen are long wearing when used properly.  Proper use includes maintaining proper height adjustment, speed and the avoidance of excessive heat buildup.  Roto Peen is designed for use on flat surfaces and not for running over weld bead or other surfaces with protruding objects. See operating instructions for more information.
