Masks definitely help, but can become uncomfortable to wear, especially over long periods of time.

You've now built a Tetra PAPRa Fan Box! + +image::https://photos.smugmug.com/Tetra-Testing/Makerfaire-2024-prep/i-VBNQgMQ/0/JCtxLtRxpqcSDdJqrXWxVHdkZN6QkP5SNx9XnN2z/X3/DSCF0360-X3.jpg[] + +== Questions == + +=== How frequently should I change the filter? === + +Changing the filter depends on how much you use the device. If you're using the device where there are a lot of particulates in the air (such as a construction site or a woodshop), you may want to change every month or so. If you're using the device where there are less particulates, every two to three months should be fine. HEPA filters just get dirtier and eventually the fan will have a hard time pulling air through the filter, and the filter should be swapped before that happens. + +=== Can I use any random HEPA filter? === + +This particular box was built around the Klein Tools p100 filter. Off-brand filters may not be as effective, so be sure that the filter is NIOSH certified. + +=== Is the fan box waterproof? === + +No, the fan box is not water proof. With the weather guard in place, water should not get into the filter directly, but increased humidity could decrease the effectiveness of the device. + +=== Any other maintenance tasks? === + +It is important to periodically check that the nuts are tight on the fan box, to ensure that the box is properly sealed against the elements. Hoses should also be cleaned periodically as well. diff --git a/content/en/v1.1/m12-controller.adoc b/content/en/v1.1/m12-controller.adoc new file mode 100644 index 0000000..50ef75b --- /dev/null +++ b/content/en/v1.1/m12-controller.adoc @@ -0,0 +1,230 @@ +--- +title: "How to build a PAPRa m12 Battery Controller (April 2024)" +linkTitle: "PAPRa m12 Battery Controller" +weight: 1 +description: > + How-To guide for building the Tetra PAPRa m12 battery controller (April 2024 version). +aliases: + - /v1.1/m12-controller + - /1.1/m12-controller +--- + +== Quick Synopsis + +The Tetra Powered Air Purified Respirator requires power to function, and the m12 battery controller provides that power for these models.

If you're using the device where there are a lot of particulates in the air (such as a construction site or a woodshop), you may want to change every few days or so. If you're using the device where there are less particulates, every two to three weeks should be fine. If the filter material gets dirty or wet, you should change it. The blue layer is intended to be water proof, but we don't know how much actual water it can take. + +## My hose is smelling. What can I do about that? + +You can clean the hose with a 22mm cleaning brush (like https://www.amazon.com/JAKIA-CPAP-Brush-Cleaning-7inch/dp/B089Q6QH1X). Soap and water should be sufficient. We've found that the hose material can begin to smell if exposed to quite a bit of sunlight, such as wearing the PAPR in the desert, and this smell wears off after some time. diff --git a/content/en/v1.1/papra-pcba.adoc b/content/en/v1.1/papra-pcba.adoc new file mode 100644 index 0000000..3f15f3a --- /dev/null +++ b/content/en/v1.1/papra-pcba.adoc @@ -0,0 +1,359 @@ +--- +title: "PAPRa Printed Circuit Board Assembly" +linkTitle: "PAPRa Printed Circuit Board Assembly" +weight: 1 +description: > + The printed circuit board assembly (thru hole version) for the Tetra PAPRa M12 controller +aliases: + - /v1.1/papra-pcba + - /1.1/papra-pcba +--- + +== Quick Synopsis == + +The following is the board diagram for the M12 controller PCB.
