MSA® Phalanx to 40MM NATO (RD40x1/7) Adapter ======================================== This prototype design for a MSA® Phalanx non-disposable respirator to 40MM NATO (RD40x1/7”) gas mask thread adapter, as requested by dclaw. 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 case, MSA® Phalanx respirators can now be compatible with any RD40x1/7” threaded canisters or step down adapters to other respirator manufacturer filter cartridges. If you cannot source 40MM NATO (RD40x1/7”) threaded filters, then you can 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 40MM NATO to Spasciani Bayonet (Duetta and Duo) 2000 Series Filter Adapter https://www.thingiverse.com/thing:4378232 40MM NATO to MEDOP Threaded Filter (EUROPA Comfort Series) Adapter https://www.thingiverse.com/thing:4380984 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. Part Description: ============= MSA_PHALANX_TO_40MM_NATO_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 RD40x1/7 threads, and may require gasket on bottom of male threads on mask side since I cannot confirm if gasket is on filter or mask side with MSA Phalanx. 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 for FDM based methods, otherwise SLS/SLA method preferred. 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/conformed respirators, adapters and accessories for their institution and workplaces. Dev. Notes: ========= 05/26/2020 - Initial model release based on MSA® Phalanx threads reported by dclaw at 7/8-14 UNF. In work, pending 3D printing community support for any fitment and model revisions. 05/28/2020 - Added quick drawing per dclaw request for QA/QC cross reference.
