Indicator "IR-2" for checking the insulated respiratory systems.

Indicator "IR-2" for checking the insulated respiratory systems is intended for checking the exploitative parameters of assembled insulated oxygen gas-masks, respirators and respiratory systems with compressed air without estimation of the index in physical units.

Technical characteristics:

• Admitted pressure drop per 1 minute in checking of hermetic sealing of respirators, gas-masks KIP-8, KIP-8M and systems with compresses air AIR, ASV-2 by means of excessive and vacuum gauge pressure 785 Pa, controlled by zone G, no more - 49



• Admitted pressure drop per 15 seconds in checking of hermetic sealing of lung oxygen inlet valve with the face part of the system ASV-2 by means of vacuum-gauge pressure 1000 Pa, controlled by zone GSH, Pa, no more - 400



• Admitted pressure drop per 1 minute in checking of hermetic sealing of IR-2 system by means of vacuum-gauge pressure 1000 Pa, controlled by zone GI, Pa, no more - 20



• Permanent continuous oxygen supply by reducing gears of respirators and gas-masks KIP-8, KIP-8M, controlled by zone D decimeters³/minutes within limits of:
  Area R - from 1,3 to 1,5
  Area KIP - from 1,2 to 1,6



• Vacuum-gauge pressure of lung governed oxygen inlet valve of respiration systems, gas-masks KIP-8, KIP-8M, systems with compresses air, controlled by zone C, Pa, within limits of:
  Area P - from 98 to 294
  Area La KIP - from 147 to 294
  Area AIR - from 0 to 196
  Area ASV-2 - from 0 to 294



• Excessive pressure of relief valves operation relief valve opening strength) of respirators and gas-masks KIP-8, KIP-8M, controlled by zone C, Pa, within limits of:
  Area P - from 98 to 294
  Area IK KIP - from 147 to 294



• Mass of indicator IR-2 without ZIP, kg - 6
