I’ve been rather indecisive about this for a long time, and as mentioned in a video earlier in the year it is about time I got a bit more serious about safety (without buying a inflatable plastic ball to live in).
One thing that I have long just accepted is air cleanliness, and have (on occasion) worn breathing apparatus, or had a fan blowing past me in the general direction of the door, or just done the work then walked out of the dust cloud for a breath. It’s amazing what we just accept for ourselves that you’d never dream of putting up within a workplace (and I’m not referring to workshop type workplaces here – if it was an office, the inhabitants would have run screaming a long time ago).
As the shed is undergoing the upgrade, I’m trying to do things just a little bit better this time around.
I was really unsure if I wanted to justify spending money on air filtration. I’ve always disliked the bad night’s sleep after a big workshop session (let alone all the black snot that is blocking the nose afterwards) So I have to ask myself – why am I using the last line of defence for my lungs as my only line of defence?
I looked at the price of different systems – the Carbatec branded one, the Jet one from Woodworking Warehouse, and the Microclene one that a couple of visitors have recently pointed out that I had forgotten about, and they were all money to put it simply.
I then thought what I really wanted to do was replace the air in the shop 6 – 10 times an hour. There is no point sucking good air in from outside – that would only dilute the dust but not be rid of it. But what if I vented the shed to the outside? That would suck clean air in all the various openings, and blow the dusty air out. Good – so now all I need is a good fan (or two). Off to Bunnings – these fans can’t be all that expensive?
Hmm – what overpriced pieces of …very ordinary stuff. Boy do people get ripped off. You can’t use a ceiling fan in a wall – the bearings will give out (and remember I’m planning on sucking dusty air through, so there would be a double insult on the bearings). Wall mounted fans – a little one, like 150mm and they were asking upwards to, and over $100. To get one with a good airflow was double that.
So I could have saved a few bob and made a box with a filter or two, and mounted a ceiling fan in it and gone that way, but no – I decided that the compromise that I always find myself doing just doesn’t ever leave me really happy with the solution, and for a bit more, I could have the real thing.
So that’s what I did. Off to Carbatec, and I’ve bought a CTF-1000 air filtration unit. You just can’t always compromise, and here is the right unit for my shed. It will filter the air in the shed greater than 12 times/hour depending on what setting I put it on. I’ll take a photo of it when I’ve gotten it installed, but for an initial view, this is from the Carbatec website:

At some stage I will reinvestigate the dust extraction itself, but first I want to install the trunking for it to my current (1HP) unit and see how it performs before deciding if I need to upgrade to 2HP. It is located in the second shed, so any dust that escapes (and dust always does from these things) doesn’t fill my workshop.
