  2. TERMINAL OBJECTIVE • 2.2.0 To familiarize FE personnel with the different respirator variants and their components, as well as maintenance and inspection procedures.

  3. ENABLING OBJECTIVES 2.2.1 Identify different variants. 2.2.2 List the components of applicable variant. 2.2.3 Discuss maintenance procedures. 2.2.4 Discuss inspection procedures.

  4. OVERVIEW • Description of CBR assemblies • Build up of CBR assemblies • Inspections of CBR assemblies • Technical support • Questions and Answers

  5. INTRODUCTION • A/P22-14 (V)1 and A/P23P-14A(V) Chemical, Biological and Radiological (CBR) Respirator Assemblies are designed to protect rotary wing aircrew from the toxic and lethal effects of chemical, biological and nuclear agents • A/P22P-14 (V)2 - 4 CBR Respirator Assemblies are designed to protect fixed wing aircrew from the toxic and lethal effects of chemical, biological and nuclear agents from ground level to 43,000 ft. • Below-the-neck (BTN) components are designed to compliment and enhance the respirator assembly function.

  6. Mask assembly Hood assembly Faceplate Orinasal mask Faceplate ripaway toggle H-Manifold MK Manifold Hood inlet adapter Hood inlet valve H-Manifold inlet valve Hood outlet valve Inhalation valve and iceguard Compensated Exhalation valve Exhalation outlet valve Snout Drinking facility Toggle harness assembly Microphone assembly Hood & Mask inlet hoses Anti-Suffocation disconnect Mask inlet adapter Nose occluder Lower assembly Manifold hoses Pusher fan subassembly J-Manifold Oxygen subassembly C2A1 Canister 90º Rubber Molding Helmet Attachment Kit COMPONENTS Click on hyperlnk for chosen component. If you wish to see all go to next slide

  7. MASK ASSEMBLY • Only size S and L are readily available. • Special Order(XL,XS,XXS) Naval Air Warfare Center Aircraft Division, Code 4.6.3.1 Patuxent River, MD 20670-1906 comm (301) 342-8850 dsn 342-8850 Back

  8. HOOD ASSEMBLY • Neck seal comes in two sizes: Standard and Small • Hood Cowl comes in three sizes: XS, Standard and XL • Can only be ordered as mask assembly. • Made of Bromo-butyl rubber Back

  9. FACEPLATE • Includes: • Nose occluder • Toggle harness • Hood/Mask inlet adapter • Drink facility • Microphone assembly • Hood outlet valve • Snout • Made of polycarbonate Back

  10. ORINASAL MASK • Two sizes designated on mask: • Large (P) • Small (Q) • Made of silicon Back

  11. FACEPLATE RIPAWAY TOGGLE • Located on lower right portion of faceplate. • Once used, the mask SHALLbe taken out of service. Back

  12. H-MANIFOLD Used to toggle between 100% O2 for variants 2-4 and ambient air from pusher fan For the A/P22P-14A(V)1-4 Back

  13. MK-2 Manifold Area where air from pusher fan is divided to go to mask for breathing and hood for cooling and defogging. For the A/P23P-14A(V) Back

  14. Hood Inlet Adapter Connects the hood inlet hose from the H-manifold assembly to the hood compartment of the mask. Back

  15. Hood Inlet Valve Located within the H-manifold. Prevents air from being drawn from the hood compartment into the orinasal mask via the H-manifold. Back

  16. H-manifold Inlet Valve Located within the H-manifold. Prevents oxygen from leaking through the pusher fan in result of pusher fan failure for the (V)2 - (V)4 configurations. Back

  17. HOOD OUTLET VALVE • Remains in the open position. • Closed if Pusher fan failure • Permits demisting air to exist the hood. Back

  18. Inhalation Valve and Ice Guard Mounted on the left side of orinasal mask. Makes it easier to exhale while preventing excessive loss of oxygen or air through the compensated exhalation valve. Back

  19. Compensated Exhalation Valve Mounted within the exhalation duct of the orinasal mask. Allows exhaled gases to be expelled into the environment when the pressure inside the mask is greater than the pressure in the outlet housing chamber. Back

  20. Exhalation Outlet Valve Fitted in the exhalation duct below the compensated exhalation valve. Will prevent the inward leakage of contaminated air in the event of the compensated exhalation valve sticking in open position. Back

  21. Snout Acts as a chamber to trap the warm exhaled air and prevents freezing of the exhalation valves. Back

  22. DRINKING FACILITY • Ensure internal drink tube (inside mask) is positioned so that it is readily accessible by aircrew. WARNING. If the canteen is disconnected in a CBR contaminated environment, do not reconnect until all matching connectors are free of contamination. Back

  23. TOGGLE HARNESS ASSEMBLY Ensure helmet attachment kit on CBR adapter straps have the dot on swivel link side Back

  24. MICROPHONE ASSEMBLY • Consists of microphone, microphone cable, and terminal plug. • Can be used for either aircraft or ground communication use. Back

  25. Hood and Mask Inlet Hoses Back

  26. ANTI-SUFFOCATION DISCONNECT • Located at the upper end of the mask inlet hose. • Manually unlocked by inward clockwise rotation of knurled locking ring. The mask inlet hose may then be separated from the mask inlet adapter by pulling firmly down on the hose. Back

  27. Mask Inlet Adapter Mounted at the left bottom edge of the faceplate. Facilitates the locking of the anti-suffocation disconnect to the faceplate. Back

  28. NOSE OCCLUDER • Mounted through nose bridge of faceplate. • Available in sizes ranging from 4-7mm, in increments of 1mm in both short and long sizes. • Either a nose occluder or butyl blanking plugs must be installed. Back

  29. LOWER ASSEMBLY Back

  30. Manifold Hoses Back

  31. PUSHER FAN SUBASSEMBLY Back

  32. J-manifold Back

  33. OXYGEN DELIVERY SUBASSEMBLY Back

  34. C2A1 CANISTER • C2 canister is being replaced with the C2A1 canister. • Ensure canister is not expired via the Naval msg that lists authorized canister lot numbers. WARNING Filter canisters do not provide protection against ammonia gas or carbon monoxide. Protection against sulfur dioxide gas can only be provided for 5 to 10 minutes. Continued next slide

  35. C2A1 Replacement Criteria • Physical damage. • Canister has been immersed in water. • Canister inlets clogged with dirt, oil, grease, or other foreign matter. • Excessive resistance to airflow or an increase in breathing resistance is felt. • The lot number of canister is listed as unserviceable in SB 3-30-2. • CB agent contamination. Continued next slide

  36. C2A1 REPLACEMENT WARNING Wear protective mask and clothing, in accordance with local SOP, when replacing or disposing of a canister that has been exposed to a toxic agent. WARNING J-Manifold gasket(s) are occasionally displaced from the manifold when the canister is removed. Visual inspection to ensure that the gasket is in place must be performed when canisters are removed or installed. Back

  37. 90˚ Rubber Molding Covers a C2A1 canister and connects to the oxygen connector that determines if that mask is a variant 2, 3 or 4. Back

  38. Helmet Attachment Kit • Necessary to integrate the respirator assembly with the aircrew helmet. • Ref NAVAIR 13-1-6. Back

  39. A/P22P-14(V)1NON-OXYGEN VARIANT Unique Components: • H-manifold blanking cap. • Uses one C2A1 canister.

  40. A/P22P-14(V)2LOX VARIANT Unique Components: • Coupling • Regulator hose for O2 system connection *Although EA-6B have LOX system with the use of the CRU-103 regulator the A/P22P-14(V)3 must be used.

  41. A/P22P-14(V)3OBOGS VARIANT Unique Components: • Bayonet connector for O2 system connection. • 90 degree elbow

  42. A/P22P-14(V)4PANEL MOUNT VARIANT Unique Components: • Quick Disconnect fitting.
