Novatek Floating Head SRAT 5" Air – SRAT5A

Novatek SRAT5A 5" Air Shrouded Grinder for Dust-Controlled Surface PrepThe SRAT5A pairs a 1.2 hp pneumatic motor with a 5-inch floating-head vacuum shroud, so you grind concrete and steel while the dust goes into your vacuum instead of into the air. The shroud floats independently of the motor, keeping the disc flat against the slab as the surface rises and falls. For crews running compressed air on the job site, the air drive removes the heat and duty-cycle limits that come with electric tools, so you can grind through a full shift without stopping to let a motor cool. Why Contractors Run the SRAT5A on AirAn air motor has no windings to overheat, so the SRAT5A holds production on continuous grinding and coating removal where an electric unit would throttle back. It needs 30 SCFM at 90 PSI through a 3/8" inlet, which a standard tow-behind or shop compressor supplies. Floating head keeps the 5" disc flat to the surface as the slab profile changes, so you cut evenly without gouging or rocking the tool. 5" disc fits tight to walls, columns, and edge work where a 7" head will not reach; trades reach into corners the larger model leaves behind. 1.2 hp air motor runs at a continuous duty cycle with no thermal cutout, so you grind a full shift without cool-down stops. Vacuum shroud captures grinding dust at the source for OSHA respirable crystalline silica compliance when paired with a HEPA vacuum. Replaceable wear skirt maintains the vacuum seal and protects the cast-aluminum shroud, so you swap a low-cost part instead of the whole housing. 5/8"-11 arbor accepts a wide range of abrasives; Scotch-Brite Coating Removal discs ship on the tool as standard. SRAT5A Applications and EnvironmentsUse the SRAT5A for concrete grinding, coating, mastic, and epoxy removal, surface profiling ahead of new coatings, and edge and detail work on silica-controlled job sites. The air drive suits restoration, industrial flooring, and abatement crews who already run compressed air and need a tool rated for continuous use.
