Post by: Charli on June 28, 2009, 07:55:26 PM
What kind of extractor fan do you have, and where did you buy it from? (If you don't mind sharing!)

After joining in Krysia's thread I am looking at getting this one
http://www.progrow.co.uk/acatalog/info_3246.html
It's more expensive but I need to be super cautious as I get asthma from time to time.

Hi!

I have a cooker hood, but I checked the airflow rate and decibels - 400meters cubed per hr at 52dB. It came frome Comet and cost about £90.

I am planning to install it about 70cm above the bench - does anyone have any more thoughts on how high it should be? I don't want to keep bashing it whenever I pull stringer, but it needs to be close to suck up all the fumes, doesn't it?

Thanks,
Cath

I got mine last week from Progrow. I ordered it Monday afternoon and it came before 11 am the next day. Not bad!

If you want to install it higher, you can improve efficiency by adding a baffle on the front, as well as boxing in the sides. My fan is quite high, but it's all boxed in so it works really well.

This kitchen cupboard makes an L with my desk, you can just see the corner on the right in the first photo. I've got a clever hubster! It's full now, and the drawer is full of frit!

There is still work to do on the ventilation and I want to make a little platform for my kiln (for when I get it) over the Ventilation and then enclose most of the space...

I do love your work space

It's looking good!

May I ask, is the silver pipe your ventilation ducting? I'm asking because bends cut the speed of the flow of air, you might find it works better if it's straightened out.

It is,  It's also not actually venting to any where at the mo.  The plan is to have it going to the right along the back of the wall and then straight up to the air brick and out that way.  But I have to go to B&Q to get some wood and a little vent that I can open for when I haven't got the ventilation going and it can then work as a proper air brick.  Once I have all the bits I think I will end up cutting down the tube to less then half at which point the left overs will go back in the box and I will put it in the for sale section here.

I haven't used it since I moved the desk over a week ago and moved all the ducting from where it was venting before.  I am hoping to be back up and running this weekend.

(all my white tubes have glass in now too)

I bought an Air Force extractor from Pro-grow a couple of weeks ago - £130 including pipe clips vat and p&p. They are based Nr Exeter. They are very helpful. Very pleased with Extractor at arrived the day after ordering.

I am watching all the ventilation posts with great interest! Winter will eventually come and open stable door and window aren't that comfortable (brrr!) :D

Krysia, the link you give shows a rectangular filter box - is this the one you actually got? http://www.progrow.co.uk/acatalog/info_4482.html  (http://www.progrow.co.uk/acatalog/info_4482.html)

hiya

I got this one

http://www.progrow.co.uk/acatalog/info_3243.html

Which is the air force 100 tornado.  Sounds like I'm talking about a mini fighter jet!

Since getting this I have been having the window closed and not got anymore dancing flame issues.  If you are not putting this in an enclosure like Mary's I would strongly recommend getting one of the stronger ones.  I know there are people that have gone for Air Force 150 Hurricane (680m3/h) (it's £146)

Oh and get it before Christmas because VAT will be going back up! (not exactly sure when though)

If you want more details of what I bought look at ....

http://www.frit-happens.co.uk/forum/index.php?topic=14575.30

It's about half way down the page - sorry don't know how to get it to the exact spot.

I got mine off the bay. It a hydroponics fan and it could probably start a tornado  ;D  I got a control unit too which is like a dimmer switch to control the fan.

I have a barley box which I built from spare double glazed glass units from my farthers works. Looks like a fish tank without the fish.

The idea that it funnels the fumes up into the fan and away better.

HTH

Loving the rod storage too, I may have to nik your idea when dad rips out the old Kitchen units.

I am thinking about a new kitchen at the mo, but I think the old cupboards are going to disintergrate the moment they are not being held together by the wall

Sorry, the ducting is obviously not fitted now I look again - duh!

The kitchen cupboards are great because they will hold the long rods with just a little tweaking - the back board is fixed to the outside ends of the walls, instead of slotted into the grooves, IYSWIM.

It's a good point though about it slowing down the exiting air and causing more of a strain on the fan - this will motivate me to get it sorted out that bit quicker!

The back of my kitchen cupboards is wall...  I can't tell you the mouse inspired panic I had last April when I saw will brown pellet type things in the front of the cupboards.  Turned out to be a beetle (erm... many many of them)  Everything in that cupboard is now in plastic containers and the beetles met the vacuum
