The blower is very quiet. It is connected via a speed controller switch which I set the desired speed on. I then use the shutter to close the air supply when I am at the anvil and open it when heating metal. I started without the shutter but the motor is rated for continuous use so more sensible to let it run. Hope this helps. Mark
Guys there are 2 hoses I just failed to get them in the shots - one from the bottom of the nozzle the other from the top. Cooling is sufficient and natural convection does give good flow but the water does get v hot. And no I haven't tried making coffee with it yet!
Kozzy, check this out. http://www.aircontrolindustries.com/applications/blacksmith-forge-fans/ The site has a USA section too. My fan is the VBL6/3. In the UK the cost was £190. The company were very helpful. Mark
