Draeger/Dräger Panorama Nova® SCBA to GOST 8762-75 (KR40H4) Adapter ============================================================= This prototype design for a Draeger/Dräger Panorama Nova to GOST 8762-75, Russian gas mask thread adapter, originally requested by diggerusha. Designed to help cross compatibility of commercial off the shelf (COTS) filters with other manufacturer’s respirators during this global PPE shortage. In this particular instance an adapter for self-contained breathing apparatus, which some overseas fire departments use, can now be compatible with any GOST 8762-75 threaded canisters or step down adapters to other respirator manufacturer filter cartridges. If you or your fire department cannot source GOST threaded filters, you can use a GOST to 40MM NATO (RD40x1/7”) thread adapter: https://www.thingiverse.com/thing:4321450 Or to minimize the stack up of adapters, use the 40MM NATO version of the Draeger Panorama Nova here: https://www.thingiverse.com/thing:4323954 And from 40MM step down to the following adapters below: 40 MM NATO to 3M™ Filter Adapter https://www.thingiverse.com/thing:4245358 40MM NATO to Scott® 742 Series Filter Adapter https://www.thingiverse.com/thing:4347531 40 MM NATO to MSA® Bayonet Filter Adapter https://www.thingiverse.com/thing:4265715 40MM NATO to MSA® Comfo Classic Filter Adapter https://www.thingiverse.com/thing:4267676 40MM NATO to Honeywell/Honeywell North® Filter Adapter https://www.thingiverse.com/thing:4268775 40MM NATO to Honeywell Sperian® Filter Adapter https://www.thingiverse.com/thing:4297348 40MM NATO to Honeywell Safety Sperian® /Survivair™ ValuAir® (Bayonet) Filter Adapter https://www.thingiverse.com/thing:4345345 40MM NATO to AOSafety® Threaded Filter Adapter https://www.thingiverse.com/thing:4273365 40 MM NATO to AOSafety® R5700 8051 Bayonet Filter Adapter https://www.thingiverse.com/thing:4265538 40MM NATO to Portwest® Bayonet Filter Adapter https://www.thingiverse.com/thing:4273464 40MM NATO to Moldex® 7000/9000 Series EasyLock® Bayonet Filter Adapter https://www.thingiverse.com/thing:4275446 40MM NATO to Secura BC Bayonet Filter Adapter https://www.thingiverse.com/thing:4294187 40MM NATO to JSP® Force™8 Filter Adapter https://www.thingiverse.com/thing:4294203 40MM NATO to Delta Plus M3000 Mars Series Filter Adapter https://www.thingiverse.com/thing:4311197 40MM NATO to Delta Plus M6000 Jupiter Series Filter Adapter https://www.thingiverse.com/thing:4311200 40MM NATO TO GOST 8762-75 Threaded Filter Adapter https://www.thingiverse.com/thing:4321450 40MM NATO to Draeger X-plore® Filter (3000/5000 Series) Adapter https://www.thingiverse.com/thing:4329276 40MM NATO to ENHA Rockman 7300 Series Filter Adapter https://www.thingiverse.com/thing:4329610 40MM NATO to Sundstrom SR Series Filter Adapter https://www.thingiverse.com/thing:4338105 40MM NATO to Milla EURMASK® ETNA (Bayonet) Series Filter Adapter https://www.thingiverse.com/thing:4342320 40MM NATO to Milla EURMASK® (Uno/New) Series Threaded Filter Adapter https://www.thingiverse.com/thing:4342343 And if no filter cartridges are still available to you, then there are many DIY filter solutions on thingiverse that are compatible with each of the major manufacturer’s respirators, for 3M, MSA, etc. May you and fellow fighters/EMTs around the world be safe and stay healthy! Part Description: ============== DRAEGER_PANORMA_NOVA_TO_GOST_ADAPTER_GEN1.stl Initial model release. Disclaimers/Risks: ============== 1.) Use Proper Gaskets Requires 40 mm OD gasket or o-ring on the interior pocket for GOST 8762-75 threads. Requires a ~33-34 mm OD o-ring on the back end of the adapter at the circumferential pocket to ensure proper seal against female side of mask. May require an inhalation gasket. Since I do not have a Dräger Panorama Nova mask I’m not sure if there is an inhalation gasket present. For negative pressure use, know that your exhale may foul the back side of the filter cartridge. 2.) Perform Proper Negative Pressure Test Follow SSPs established by your institution or workplace for further guidance. But in general, don your respirator, adjust straps till taught against face, ensuring no obstructions around the periphery of the seal against face either due from hair, facial hair, or otherwise. Exhale deeply. Cover all inhalation ports. (Typically, most full face or half face respirators have two filters, so cover those intake ports with your hands. If your running only one filter, ensure the opposite port has filter cap in place.) Now inhale deeply. The mask should suck tightly against your face without any air leakages. Re-test if adjustments are required at gasket/o-ring interfaces at the adapter. 3.) Use At Own Risk – Temporarily Solution Only Until Supply Chain Normalizes 3D printing materials are not resistant to many solvents, are water soluble, and degrade when exposed to chemicals, heat, and UV/sunlight. 3D printing this adapter is only a temporarily ad-hoc solution against biological contagions. In addition to using a properly calibrated 3D printer, due to tolerances of adapters, if possible perform hot nozzle pass on all exterior surfaces, to reduce surface porosity. Highly recommended users apply a thin layer of polyurethane clear coat on all exterior surfaces, spray or dip based methods, to help resiliency and durability for repeated sterilization and to reduce fomite transmission in printed infill layers. Once supply chains return to normal, users should purchase OEM OSHA/NIOSH/EN standard approved respirators, adapters and accessories for their institution and workplaces. Dev. Notes: ========= 04/27/2020 - Initial model release. In work, pending support 3D printing community for any fitment and model revisions.
