    To cope with this demand, we developed the new Model PDA-100M based on the current Model PDA-100D. The motor of the new Model PDA-100M is more durable than that of the current Model PDA-100D thanks to the double insulation construction. We aim to expand our market share with the new Model PDA-100M.
