Thread: Trito Respirator - PRE FILTER UPGRADE

Thanks for the lead on this.

I have tested the prefilters on these respirators with air flow meters and even when clogged haven't found them to be that significant in terms of restricting flow. I still have the original spare prefilter and it has not been used simply because the original one have never permanently clogged. I guess that depends on how dusty the work environment is but I found just stopping and tapping the build up off the filter restored the flow back to its original "ordinary" state. If it did get clogged where a tap or 2 would not clean it, a quick blast with compressed air seemed to do the trick.

Back in Jan this year I tested the flow in detail of my respirator because, even though the ping-pong ball indicator show it to be working, I have always found it to not deliver enough air insufficient for working in a hot/warm space. I even added a set of Li-ion batteries with higher V to see if that would improve the flow. This worked to some extent but I would like to have it provide maybe double the flow and it seems like the small plastic impeller cannot provide enough pressure to blow sufficient air through the P2 filters.

As someone pointed out - it is a budget priced device so don't expect too much
