The suction regulators can be classified into Three Mode and Two Mode as following;
· Three Mode and Three Mode High
The Three mode Standard and High Continuous models provide adjustable vacuum from zero to full-line vacuum. The Three Mode models include a MAX mode that provides immediate, unrestricted full-line vacuum for emergencies.
· Two Mode and Two Mode Low
The Two Mode Continuous Vacuum Regulator regulates vacuum levels from zero to full vacuum with a gauge increments up to 200 mmHg. The Two Mode Low Continuous Vacuum Regulator restricts maximum negative pressure for those procedures requiring low negative pressure and limited vacuum.
