The Silente has been designed to operate at a very low noise level. The large diameter body provides space for clear, widely spaced calibration and incorporates a “pull-twist” action to prevent accidental adjustment.

The twin-jet design offers the user seven oxygen concentrations. The increased body diameter provides space for clear, widely spaced calibration and incorporates a ‘pull-twist’ action preventing accidental adjustment. The one-piece design eliminates the need to use more than one valve for all concentrations and there are no separate pieces to get lost or mislaid.

The concentration delivered is unaffected by the patient® breathing pattern provided that the optimum flow indicated on the valve is set on the oxygen flow meter.

Key Benefits:

• The appropriate flow range is selected to suit the desired concentration
• The outer ring with its pull-twist action selects the prescribed oxygen concentration
• A flow in L/min is printed above each concentration indicating the optimum flow meter setting.
• The Silente delivers precise oxygen concentrations. This accuracy is independent of the oxygen flow meter setting and is achieved using just one valve.
