Sundstrom SR Series Filter (SR100/200/900) to 40MM NATO (RD40x1/7) Adapter
This prototype design for a Sundström SR series respirator (SR100/200/900) to 40MM NATO (RD40x1/7”) gas mask thread adapter. Designed to help cross compatibility of commercial off the shelf (COTS) filte with other manufacturer’s respirato during this global PPE shortage. In this particular case, Sundström SR series respirato can now be compatible with any RD40x1/7” threaded caniste or step down adapte to other respirator manufacturer filter cartridges. Note Sundström SR200 series are already factory threaded for RD40, just removed the OEM filter adapter.
If you cannot source 40MM NATO (RD40x1/7”) thread filte, then you can step down to the following adapte below:
40 MM NATO to 3M™ Filter Adapter
40MM NATO to Scott® 742 Series Filter Adapter
40 MM NATO to MSA® Bayonet Filter Adapter
40MM NATO to MSA® Comfo Classic Filter Adapter
40MM NATO to Honeywell/Honeywell North® Filter Adapter
40MM NATO to Honeywell Sperian® Filter Adapter
40MM NATO to Honeywell Safety Sperian® urvivair™ ValuAir® (Bayonet) Filter Adapter
40MM NATO to AOSafety® Threaded Filter Adapter
40 MM NATO to AOSafety® R5700 8051 Bayonet Filter Adapter
40MM NATO to Portwest® Bayonet Filter Adapter
40MM NATO to Moldex® 7000/9000 Series EasyLock® Bayonet Filter Adapter
40MM NATO to Secura BC Bayonet Filter Adapter
40MM NATO to JSP® Force™8 Filter Adapter
40MM NATO to Delta Plus M3000 Ma Series Filter Adapter
40MM NATO to Delta Plus M6000 Jupiter Series Filter Adapter
40MM NATO TO GOST 8762-75 Threaded Filter Adapter
40MM NATO to Draeger X-plore® Filter (3000/5000 Series) Adapter
40MM NATO to ENHA Rockman 7300 Series Filter Adapter
40MM NATO to Sundstrom SR Series Filter Adapter
40MM NATO to Milla EURMASK® ETNA (Bayonet) Series Filter Adapter
40MM NATO to Milla EURMASK® (Uno/New) Series Threaded Filter Adapter
And if no filter cartridges are still available to you, then there are many DIY filter solutio on thingivee that are compatible with each of the major manufacturer’s respirato, for 3M, MSA, etc.
Part Description:
SUNDSTROM_SR_SERIES_TO_40MM_NATO_ADAPTER_GEN1.stl
Initial model release.
DisclaimeRisks:
1.) Use Proper Gaskets
Requires 40 mm OD gasket or o-ring on the interior pocket for RD40x1/7 threads.
2.) Perform Proper Negative Pressure Test
Follow SSPs established by your ititution or workplace for further guidance. But in general, don your respirator, adjust straps till taught agait face, euring no obstructio around the periphery of the seal agait face either due from hair, facial hair, or otherwise. Exhale deeply. Cover all inhalation ports. (Typically, most full face or half face respirato have two filte, so cover those intake ports with your hands. If your running only one filter, eure the opposite port has filter cap in place.) Now inhale deeply. The mask should suck tightly agait 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 UVunlight. 3D printing this adapter is only a temporarily ad-hoc solution agait biological contagio. In addition to using a properly calibrated 3D printer, due to tolerances of adapte, if possible perform hot nozzle pass on all exterior surfaces, to reduce surface porosity. Highly recommended use 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 tramission in printed infill laye. Once supply chai return to normal, use should purchase OEM OSHA/NIOSH/EN standard approved respirato, adapte and accessories for their ititution and workplaces.
Dev. Notes:
05/02/2020 - Initial model release. In work, pending 3D printing community support for any fitment and model revisio.
