Thread: Face shields and breathing masks

All hail the long awaited Triton .....
Check Trition
And have a look at Triton Times on the front page ... it should be out in a few weeks. I tried to ask the Triton guy at Bunnies on the weekend as he didn't have anybody around but he wouldn't stop playing with his bloody toy.

Stinky.

I have a Trend Air Shield RRP is $499.00 but you can pick it up for less at the Wood Shows.

At our Woodcraft Guild meeting last night, the local Tasmanian Triton demonstrator indicated that the Triton would be available shortly RRP would be about $295.00.

I use the Trend air shield too - expensive, but then lungs are priceless. And I use a workshop dust filter. They've come down a lot in price here in Oz. In your patch, well, as I said, lungs are priceless!

I use a standard face shield - about $30 and a 3M respirator - $70 + approx $25 for filters and cartridges. The advantage of having the 3M is that you can change the cartridges to suit what you are using.

I used mine in a shed throughout summer for 8 hours a day in 35+C heat and as long as you have some paper towel handy it isn't too bad.

It seems the longer the delay on the Triton the higher the cost ... initially it was about half of the competitors ($250) then $275 now $295. It seems that the publicity shots that were delaying its release may be costing more than first thought and the price will be passed onto the consumer. Oh well ... even at $300 it sounds like a good unit and I await the reviews with baited breath.

Stoppers .... Stoppers .... Stoppers ..... Please get with the program ... you will really need to brush up on your product testing techniques before the SA Woodshow otherwise you will be shown up as a fool.

The purpose of the baited breath is to test the filtering properties of the mask. Step one .... fill your mouth with copious amounts for unrefrigerated bait .... step two ..... fit the mask to the face .... step three .... breath .... stand back and test the effectiveness of the mask. Work colleagues or the wife will quickly tell you the quality of the mask.

I am so glad that I could give you this quick refresher course before the next show.

Sir Stinkalot you have not seen what doorstop can do to a bowl of baby octopus. No mask is good enough after this.

A Racal with a charcoal filter will stop a fart so it will sure as hell stop Stoppers and Stinkies bait breath.

I'll bet the Triton won't.

12 mths ago I purchased a Purelite helmet. VERY EXPENSIVE but I want to see my children grow up! It is very light with battery lasting heaps longer than any other I looked at. Battery is also centrally located in top of lid so as great balance is achieved.
Not thesort of thing you find at any old harware store. these are a specialty safety supply unit.
just over $1k but pretty good value I reckon!

I would tend to agree that the Trition isn't going to be as effective as some of the units at twice the price ..... but for a starting point for the weekend user it looks as if it would be a good buy. If I was working a 38hr week in the shop then $1K for a good quality mask would be one of the first investments. I find for the stuff that I do the respirator with the big filter mounted on the front works well but in the summer its a pain, and it also hampers my singing . Keeping dust out on the lungs is a high prority but in my case it will have to go in stages.

What does happen to the fine dust that enters the lungs?

Here's a challenge for Wayne - Design and build a portable Cyclone suitable for attaching to your face.

Stinkalot and Stoppers could model it for the publicity shots and Neil could distribute it. I'll be your first customer.

What could it be called though?

- Wood Borer

wouldn't it have to be the UB-Cyclo Stink-stopper?

can't figure how to get Wayne's name into it just yet

Hi,
The Triton respirator is on store shelves now.
I saw one at Bunnings priced at $272 although I believe the recommended is $275
The unit uses 2 standard cartridges (like my standard unit) which could quite easily be replaced with better quality ones.
It is extremely light with most of the weight located in the belt mounted filter houseing.
Filtered air is passed into the rear of the hard hat and evenly distributed (via a slot at the front) down the inside of the polycarbanite shield at ambient temp, so keeping the face cool.
The skirt is great for keeping dust etc from getting in around the collar of your shirt as an added advantage.

This is a truely great product, which probably is why Tritons first manufacturing run has been sold with the second to be arriving in next week or so.

Hope this helps

Air that passes through the nasal area and past the windpipe enters the air tubes (bronchi) leading to the lungs. These airways are lined by mucous producing cells. This mucous catches most of the dust particles (in a stream of air and dust moving through a pipe the solid dust matter will tend to follow its straight course at a bend and hit the side of the pipe rather than take the corner with the air - in the lungs this would stick to the mucous - it's the same principle behind not having 90 degree bends in you dust extraction piping). Tiny hairs called cilia, covering the walls of the air tubes, move the mucus upward and out into the throat, where it is either coughed up and spat out, or swallowed.

Dust that reaches the sacs and the lower part of the airways where there are no cilia is attacked by cells called macrophages. Macrophages encapsulate the foreign particles and in a way that is not well understood, move outwards until they reach the part of the airways that is covered by cilia. The wavelike motions of the cilia move the contaminated macrophages to the throat, where they are spat out or swallowed.

Besides macrophages, the lungs have another system of protein formation for the removal of dust. The lungs can react to the presence of germ-bearing particles by producing certain proteins that attach to particles to neutralize or kill them.

Just out of interest here's roughly how far different sizes of dust make it into the lungs:

• 5 - 30 µm - Nasopharyngeal Region (upper airway passages - nose and throat)
• 1 - 5 µm - Trachea, Bronchial and Bronchiolar Region (windpipe and larger branches of the lungs)
• 1 µm or less - Alveolar Region (smaller branches of lung and the air exchange area)

There you have it, in all it's relative uselessness
