How to build a PAPRa Fan Box (96mm)

How-To guide for building the Tetra PAPRa fan box (96mm) (April 2024 build).

Quick Synopsis

The Tetra Powered Air Purified Respirator requires that the air be purified; this purification is accomplished by powering a fan to pull air through a filter and then pushing that purified air through a hose to a mask worn on the face. This section contains the instructions for building the box that holds the fan and filter.

The main goal of this iteration of the fan box is to reach N99 filtration levels by ensuring that the power connector is dustproof and using an IP68-rated BNC jack.

WARNING: we provide no warranty, implicit or explicit, that this device will work up to an N95 specification, when built outside of a facility rated to do so. The only way to truly test one of these devices using something like a Portacount under controlled conditions.

This particular version of the PAPRA has been tested to pass at an N99 level, and likely passes at an N100/P100 level, since the build uses P100 filters. We do not have the equipment necessary to validate that this device passes at a P100 level.

Gaskets

Gaskets should be cut from 2mm craft foam. Ideally, they should be cut by something such as Cricut (https://www.cricut.com/), but can also be cut using scissors or an Xacto knife so long as the templates are followed closely. The Cricut uses the supplied SVG files, and other cutters can use the supplied DXFs.

How to build a PAPRa Fan Box (96mm)

How-To guide for building the Tetra PAPRa fan box (96mm) (April 2024 build).

Quick Synopsis

The Tetra Powered Air Purified Respirator requires that the air be purified; this purification is accomplished by powering a fan to pull air through a filter and then pushing that purified air through a hose to a mask worn on the face. This section contains the instructions for building the box that holds the fan and filter.

The main goal of this iteration of the fan box is to reach N99 filtration levels by ensuring that the power connector is dustproof and using an IP68-rated BNC jack.

WARNING: we provide no warranty, implicit or explicit, that this device will work up to an N95 specification, when built outside of a facility rated to do so. The only way to truly test one of these devices using something like a Portacount under controlled conditions.

This particular version of the PAPRA has been tested to pass at an N99 level, and likely passes at an N100/P100 level, since the build uses P100 filters. We do not have the equipment necessary to validate that this device passes at a P100 level.

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.

PAPRa Build Guide (April 2024 Edition)

How to build the April 2024 version of the Tetra PAPR.

Quick Synopsis

This guide will walk you through how to build a Powered Air Purifying Respirator, also known as a PAPR. We assume that you have some knowledge of 3D-printing, and cutting foam with a knife or using a stencil or a cricut, and perhaps some soldering. In the end, you will have four things: a box with a filter and a fan in it, a second box with batteries and a fan controller, a mask, and straps and hoses to hold it all together.

Please note that this system will not protect you from anything landing in your eyes. For that protection, either the mask will need to be modified to be a helmet or you will need a face shield.

WARNING: we provide no warranty, implicit or explicit, that this device will work up to an N95 specification, a P100 specification, or any other standard, when built outside of a facility rated to do so. The only way to truly test one of these devices using something like a Portacount under controlled conditions.

Please refer to the Testing section for the flow and fit testing done to verify PAPR functionality.

Parts needed

The entire set of parts to build the PAPR is:

tinkerer SKU updated M

There are three components to build:

  1. The M12 Controller

  2. The Fan Box

  3. The Mask

And the instructions to build all of these components can be found in the Tetra PAPRA Components section.

How to build a PAPRa m12 Battery Controller (April 2024)

How-To guide for building the Tetra PAPRa m12 battery controller (April 2024 version).

Quick Synopsis

The Tetra Powered Air Purified Respirator requires power to function, and the m12 battery controller provides that power for these models. The controller consists of internal circuitry, a potentiometer to adjust fan speeds, a cable to connect to the fan box, and a port for a Milwaulkee M12 Battery to be inserted.

This build differs from the v1 version in that it uses a custom-built circuitboard to remove many of the difficult steps of the build, add a battery charge indicator, and a separate power port for use in a car. If you cannot get the custom board, then please refer to the v1 version of this guide.

WARNING: we provide no warranty, implicit or explicit, that this device will work up to an N95 specification, when built outside of a facility rated to do so. The only way to truly test one of these devices using something like a Portacount under controlled conditions.

Parts Required

This build will require printed parts, purchased parts, and several tools. Here is a picture of all the components used in this build:

How to build a PAPRa Mask (June 2022 Version)

How-To guide for building the Tetra PAPRa mask (June 2022 version).

Quick Synopsis

The Tetra Powered Air Purified Respirator requires a Mask component to deliver purified air to the face of the wearer. This mask will be connected to the Fan Box via a CPAP hose. After many rounds of development, we have decided to adopt a 3M 6500 series mask as the final interface to the face of the user. These masks are effecive, cheap, and readily available. Ideally, future work can have a fully open source mask to be used here, but our attempts just aren’t equivalent to this off-the-shelf part.

WARNING: we provide no warranty, implicit or explicit, that this device will work up to an N95 specification, when built outside of a facility rated to do so. The only way to truly test one of these devices using something like a Portacount under controlled conditions.

Build Steps

Cut the ventilator hosing into 2 foot lengths.

Place the right-angle parts (P-TET-000150) onto the mask:

MMR5821 L

Note that the part has three different-size teeth to meet:

MMR5823 L

Once in place, the part twists in place:

MMR5824 L

The other right angle part goes into the opposite side:

MMR5825 L

Place the two stiff pieces into the y-connector (P-TET-000151):

MMR5830 L

Connect the CPAP hose in place on the bottom of the Y-connector (P-TET-000151):

MMR5838 L

Connect the other end of the CPAP hose to the other side:

MMR5841 L

The mask is all together:

MMR5845 L

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 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.

How to build a PAPRa Mask (June 2022 Version)

How-To guide for building the Tetra PAPRa mask (June 2022 version).

Quick Synopsis

The Tetra Powered Air Purified Respirator requires a Mask component to deliver purified air to the face of the wearer. This mask will be connected to the Fan Box via a CPAP hose. After many rounds of development, we have decided to adopt a 3M 6500 series mask as the final interface to the face of the user. These masks are effecive, cheap, and readily available. Ideally, future work can have a fully open source mask to be used here, but our attempts just aren’t equivalent to this off-the-shelf part.

WARNING: we provide no warranty, implicit or explicit, that this device will work up to an N95 specification, when built outside of a facility rated to do so. The only way to truly test one of these devices using something like a Portacount under controlled conditions.
