The BOS-2000-2 is an automatic system that works with the easy push of a button.  The pump head is powered by two (2) AA batteries and gives firm results in a short period of time.  This simply designed pump head allows the user to activate the motor with minimal effort.  The BOS-2000-2 has been a customer favorite for over 20 years because it is so easy to use and assemble.  This is a quick and powerful vacuum that comes ready to use right out of the box.

The BOS-2000-2 Pump Head has an Internal and External safety release valve.  The Internal Release Valve will automatically activate if too much pressure has been created by the vacuum.  The External Safety Release can be activated by pressing a red button on the pump head.  After passing rigorous safety tests, this Pos-T-Vac system is approved for marketing by the United States FDA.
