    The compressed gas is supplied from the central supply system (CS) or from an O cylinder with pressure regulator. The operating pressure of the Oxylog 1000 is between 2.7 bar and 6 bar. CAUTION Risk of damage to equipment! Dust, oil and humidity in medical gases may impair the functioning of the equipment or damage it.

  • Page 15: Frequency Control

    Oxylog 1000 Function Description Frequency Control When the unit is off, driving gas flows via the manifold and through the dosage valve D2 to the 3/2-way valve DMR5 and to DMR6. In consequence, DMR6 switches through and the switching valve WV1 switches to expiration.
