The Twin-O-Vac is a venturi actuated suction unit which features two self sealing oxygen supply sources to
facilitate multiple therapy applications.The Twin-O-Vac may be connected directly to an oxygen
pipeline or a cylinder regulator with a pre-set deliverypressure. Flowmeters and other accessories should be
ordered separately.A vacuum gauge fitted to the head of the Twin-O-Vac
indicates the vacuum generated by the unit. Two basic models are available, one with a high suction
capability up to approximately -400 mmHg (-53 kPa) and the other with a lower suction performance pre-set
to provide a maximum of -200 mmHg (-26 kPa).
