RD40 & APA - ARIA Masks
APA - Aria Protection Adaptor ( Mask and Filter not included)
An adaptor that connects Ocean Reef manufactured snorkeling masks to P3 and other types of filters transforming the snorkeling mask, into an emergency personal protection mask. The product is sold together with RD40/22 an adaptor that connects rd40-22mm inlets to 40mm 1/7″ threaded outlets. With this adaptor, you can connect an APA or EPA, or SGE Gas Masks to rd40-22mm devices such as Pall breathing filters, or similar.
APA Package Includes
1. RD 40/22: This piece connects rd40-22mm inlets to 40mm 1/7″ threaded outlets. With this, you can connect an APA or EPA, or SGE Gas Masks and other PPE that use the NATO 40mm standard, to rd40-22mm devices such as hydrophobic bidirectional filters, or similar that can commonly be found in hospitals. We have learned that these hydrophobic bidirectional filters have a very low breathing resistance and have excellent performances in protecting from contaminations, as well as having a very long duration. We are in no way related to filter manufacturing, maker or have tested such equipment.
The rd40-22mm adaptor can be screwed on the APA. The hydrophobic bidirectional filter can then be inserted into the female connection.
2. Mushroom valve: A silicone valve that is commonly found in the scuba industry and that we make out of our own design and mold. Failure to include this part, misplacing or breaking can result in rebreathing exhaust air inside the filter again, incrementing the dead air space of the mask.
3. Gasket: This EPDM gasket is die-cut and produced by us out of our design. Misplacing such gasket, breaking, substitution with different parts can result in leaking outside air into the mask, bypassing the filter.
4. Zip tie: Included to secure the filter connector and reduce the possibility of losing the filter and adaptor if getting entangled due to bulky filter.
