Product Code: AVI-2014 Category:


The S-ORC ensures a minimum fresh gas oxygen concentration of 25% at all times to avoid hypoxia. The N2O is cut off automatically if the Oxygen supply fails or when the O2 flow meter knob is inadvertently closed. The patient can never get ventilated on N2O alone.

Many key components are imported to insure highest level of reliability.

Fitted with special, second stage regulator for stable working pressure and safety.


International standard circle system with highest absorption efficiency. Easy to refill & change canisters. Unique designs allows for use of single or dual canisters. Total absorber capacity of 2.5 Ltr.

Incorporates calibrates Airway Pressure Limiting Valve (APL) and single outlet for waste gas. Circle absorber can be connected to gas scavenging system.
