New Fan, New Aches but No Toxic Gases

Well I finally got the new fan installed on boxing day. The original plan was for a day off (I've heard of those) and go out, but it seems it's business as usual when OH got called to work instead, so I figured I might as well use the time productively.

I was going to get a boxed acoustic fan, to keep down some of the noise, and know they are quite popular with many lampworkers, although I wanted something with a bit more power. I'd almost settled on one when I came across some reviews on a hydroponics forum, for which many of these fans are made. The reviews were good, but many of the mentioned a TD-Silent being the best and most reliable they'd come across. Price-wise they seemed pretty good for the money too, the one I wanted only had a 19db level too, so took a deep breath and placed my order.

I didn't quite expect something that looked like it had fallen off a military jet! I didn't get around to taking a picture, so here's a quite You-Tube link for those considering one! TD-Silent video

 The one I got has a massive 200mm intake and outlet, so the first job was stripping out the old fan, which it turns out might have needed a bit of a clean!

Old fan from the original cooker hood
 I've kept and used the switches from the original unit, it wasn't until the new fan turned up that I found it has two speed so needed more switches to control it. At the same time I took out the lights (which were in the wrong place so never used) in the cooker hood and just about anything that might block the airflow.

Straight up and into the outside world for you Mr nasty toxic carbon monoxide!

From there it was time to seal up the sides of the chimney. Originally I'd intended to use a big 200mm pipe I'd bought for the job, but since the old cooker extractor had a nice chimney that was nearly the same size I figured it would do just as well. A quick trim of some spare aluminium sheet, then a little duct tape to seal any gaps and holes and the job was nearly done. Or so I thought! A joist was in the way so everything came down so I could move the whole canopy over just 3 inches!

Shiny! There really is only one exit, but the mirror inside of the chimney makes it look like three!
After another hour or so of clambering around in dark and dirty, and very uncomfortable, spots to get a small bend of flexible tube attached and sealed, the job was really finished. It's not a very tidy or as neat looking as I'd wanted (I went a bit overboard with the duct tape!) and needs a bit of trunking to hide away the leads. It is quiet though, and a quick test with an incense stick showed even on low power it whisked it away with no problems. On high power I barely even saw the smoke leave the incense stick, it was just gone! Not as quiet as I thought, there is quite a rush of noise from the air moving, however when stepping just a few feet away I could hardly hear it, a huge improvement on the low rumble the old one used to generate.

Needs a bit of a clean, but despite the bodging it has nearly doubled the amount of air this old cooker extractor hood can remove
I'd expected it to take two days to get everything in place, so was pleased to get it done, despite the odd set-back, in a day. However today I've woken up with so many aching muscles and bruises I've got hardly anything done, thus getting chance to sit and blog, so maybe my original schedule was right after all!

I still am not sure if I'll be back to Greenwich between now and new year, I am sure I'll get around to a break sometime in the next few weeks if not! I hope you have all head a great Xmas, and may I be the first to wish you all a happy 2013!
