The RPT5E1 portable wash water recovery/transfer unit has recently been upgraded to include three new value added features. High water level shutdown: If recovered water inside the holding tank gets too high, the ball float will activate the vacuum shutoff, protecting the vacuum components and preventing the RPT from overfilling until the transfer pump catches up. Upgraded filter bag system: The new filter bag system makes it easier for the user to clean or replace their filters. Internal tank structure: When recovering high temperature water, the internal wall supports ensure the holding tank will keep its shape against the vacuum suction.
