The MDF35 long-reach air tool from General Equipment uses an internal valving mechanism, which allows the piston to deliver increased kinetic energy per blow. Featuring steel barrel construction and weighing 18.5 pounds, the MDF35 requires a flow rate of 11 cfm at 90 psi and produces 3,100 blows per minute. It is designed for a wide variety of applications including the removal of floor tile, mastics, adhesives and general concrete as well as stripping material build-ups.
