Who manufactures these machines that sit on the roof, and vent the xenon exhaust?

"Would you like fries with that?"

There are many companies that manufacture rooftop exhaust fans and many are stocked at www.wwgrainger.com

Ozone you breathe is bad.

Ozone in the stratosphere is good.

I was the leader of the Kodak team that developed Particle Transfer Roller (PTR) film cleaning, which has saved millions of pounds of ozone-depleting solvent from destroying stratospheric ozone:

Last Tuesday, April 22, ten Kodak people traveled to Washington DC to receive the award. Quite a thrill.

Way to go, John. An Oscar and now this!! Your commitment to the industry is commendable and inspiring.

Now all we have to do is find a way to vent ozone-producing xenon lamps up to the stratosphere to replenish the ozone!

I don't think Grainger sells a "Stratospheric Exhaust Fan" to put the lamps ozone into the stratosphere, where it's needed.

The types of exhaust fans for lamphouse exhaust are typically listed in catalogs under the heading of "Ventilators, Rooftop". These also need what's called a 'curb kit' to install it on the roof.
Here's some Grainger part numbers to try:
7A547
7A548
4HX80
4HX91
4HZ36
4HZ37
4HZ40

Johnstone Supply (www.johnstonesupply.com) also carries some of these fans such as the FloAire brand # 2C912 (Johnstone's part number is X89-548).

Most theatres up here use Delhi fans typically the 414 model

Do you have a link for that Gordon?

OK... you guys are giving out part numbers left and right... try this.

I've got a 4kw Xenex II lamphouse riding on the back of a Simplex XL and Sh1012 soundhead. I need to spec an exhaust fan for the lamphouse.

Somebody give me a model number. Grainger numbers work good. I can go out the back door here at the office and throw a rock and hit the Grainger Building (although I've never really wanted too!)

Just stroll over to Graingers and tell them you want 600 cubic feet per minute cruising through that lamphouse. They'll set you up.

Ok, I've been out of the business for sometime so..., I understand the need to vent the carbon arc but outside of removal of heat from the booth is there a "NEED" to vent the new blubs beyond the exhaust fan on the lamphouse??

Yes there is a need to vent the exhaust from a xenon lamphouse to the outside.

First of all xenon lamps emit ozone, which isn't good for humans to breathe.

Second of all the lamps will heat up your booth beyond all reasonable comfort and increase your air-conditioning costs far beyond the installation costs of an exhaust fan. Heat has a detrimental effect on worker comfort, health and may contribute to the premature failure of electronic components.

I'm so tickled that my new house has exhaust fans that vent outside for my stove, shower and dryer.

A cinema tech I knew has four cats. He installed an outside exhaust fan in a cabinet for his cat box. I think even the cats appreciated it.

I have heard of a cinema tech who changes all the exhaust fans in his amps and soundtrack to they blow one way and then vents the whole rack to the outside as well.

Thank you, I thought the ozone was the case as for the heat, my booth loucation and size of my booth space I would have no problem with the heat aspect.
