Author Topic: Exaust fan. How important? Tim Reed Better Projection Pays Posts: 5246 From: Northampton, PA Registered: Sep 1999 posted 04-30-2008 09:45 AM                       I've been seeing a lot of these in lieu of roof blowers. I've always thought they were probably okay for emergency use, but not everyday! There's theatres out there running with these things.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 04-30-2008 10:32 AM                     I use these fans with very good luck http://www.elicent.it/inglese/axcmet.html# and they are very quiet  |  IP: Logged Bill Enos Film God Posts: 2081 From: Richmond, Virginia, USA Registered: Apr 2000 posted 04-30-2008 12:30 PM                     We're using Elicent AXC 200B on both of our film machines and the Barco DP100 along with a roof blower. They are very quiet and move more than 650 CFM each. All ball bearing motors and all steel construction. For us they have been well worth the price.  |  IP: Logged Derrick Huggins Film Handler Posts: 27 From: Gotham City Registered: Feb 2008 posted 04-30-2008 01:32 PM                    Thank you all for your reply's. I think i am going to make a short video of all the poor working conditions that i have at my theater. If anything it will be amusing to watch, and perhaps if there are certain conditions that are fire hazards, or safety issues you guys could point out, so perhaps i can anonymously report him to the proper authority. That seems to be the only way anything will get fixed. If he has no other choice.Any suggestions where would be a good place to upload the video? (you tube, meta, etc)Well thanks guys. Be sure to look for my new movie project: "How NOT to run a theater" Coming soon  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 청주시, 경북도, South Korea Registered: Mar 2007 posted 04-30-2008 02:32 PM                     It's not so anonymous, though, when you openly discuss it on a website. And methinks if your boss finds out about this he's gonna let you go pretty quick. So be careful.  |  IP: Logged Derrick Huggins Film Handler Posts: 27 From: Gotham City Registered: Feb 2008 posted 04-30-2008 02:43 PM                    Good point. I doubt he reads these forums, but someone here may know him. Oh BTW Chris, about replacing bulbs. its not that i personally want to wait until the screen is black, problem is, we are not authorized to change bulbs without owners consent. hell even if we wanted to its not like we have any spares there.your talkin about a guy, who has his projectionist manager running scope films with the curtains still set to flat, so the film shows on the side. and he is my superior. simply because he doesnt want to bother to reprogram the automation. ( he might not even know how to do it)  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 04-30-2008 03:53 PM                     Dang, with horrible working conditions like that,sounds like you need to scoot to another theatre or occupation - for you know that you aint gonna change things the way you think or know how they should be. Sad thing, is that these kind of people are 'dead right in themselves' and even though you have great motives in making things better, this will surely offend him in the way that possibly 'someone is showing him up that things can be run better'..even though he knows he's wrong in operational procedures but either 1)-not admit it (which is the usual first case), or 2)-this is how he's gonna do his business and nobody is going to alter it in any means or form. Bottom line: he's prob the guy who doesn't want any sort of competition within his business. For if you show any form of competition, he'll give you two choices - either live within his operational pattern, or hit the road onto something else. I call it "the Pyramid Operation" since one person only is allowed at the top and the ones below him, on both legs, do his bidding. You might say, people below him are working for him to fulfill his dreams. (Rather horrible working conditions, if you ask me ...) Trust me: been there and done that in this industry and still came up short in trying. Thus, esp in your situation, either live with it, or bail to something better. Good luck - Monte  |  IP: Logged Bill Enos Film God Posts: 2081 From: Richmond, Virginia, USA Registered: Apr 2000 posted 05-01-2008 12:31 PM                     Something that worked with a guy I worked for a while back was to drop a hint over and over until one day he thought it was his brilliant idea and had it done.  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 05-02-2008 01:45 AM                     In 26 years I've found the biggest battle with owners (and contractors on new construction) is getting them to install an exhaust system for the machines that meets specs. The owners and contractors bitch about the cost, the HVAC engineers want a freaking BTU and Calorie per hour (yes one HVAC contractor actually asked me for that spec) that the lamp puts out. I've found that the only way to get what's needed at the stack is to ask for +150% of what you want, then you'll get what you need. Current bid I'm doing now, I want 450cfm per machine, so I asked for 600. So I should end up with the 450cfm I really need. Oh, and for land's sake don't mention the "O" word. Especially on a government job. That'll trigger a whole slew of data requests and environmental impact reports. (For those who don't get it, the word is Ozone.)(And of course, virtually all modern xenon bulbs are ozone free.)  |  IP: Logged Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 05-02-2008 02:27 AM                        Well, actually they are now ozone free-ish. They still put out ozone but not in the amounts that they did before the manufacturers realized they would have projectionisists coming down with all kinds of bronchial ailments if they didn't do something about it. Actually, even when they did give out lots more -- I think I heard long ago that the first bulbs gassed out more than 15 times what they do now -- if you exhaused them properly and I guess if you weren't so stupid as to stand next to the lamphouse all day with your nose pressed against the snout, taking in deep breaths, it wouldn't do you any harm. I mean if you could survive years in a carbon arc booth with the toxic soup THAT stuff belched out, you certainly could survive that nice fresh smelling ozone. I never could figure out what the big deal was anyway....just pump the ozone out the stack and it will plug up the supposedly big hole in the ozone they were always whining about. Either you're depleating the ozone with spray deodorant or you're making to much with your xenon bulbs and the Ionic Breeze. You can't win with these people.  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 청주시, 경북도, South Korea Registered: Mar 2007 posted 05-02-2008 09:32 AM                     quote: I never could figure out what the big deal was anyway....just pump the ozone out the stack and it will plug up the supposedly big hole in the ozone they were always whining about.

[Roll Eyes] I'm astounded that you couldn't get it. Something needed many miles up in the atmosphere isn't something that's necessarily good to have in large levels here at ground level.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 05-02-2008 09:36 AM                     Smog is often caused by ozone at low heights The engineer is correct to ask for BTU amounts as sizing of the booth HVAC needs that information as is the amount of exhaust as otherwise there will not be enough makeup air and the booth will be at a massive negative pressure  |  IP: Logged Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 05-02-2008 12:30 PM                        Chris, I am astounded that after all these years, you don't get my ascorbic, wry and often wildly amusing sarcasm!  |  IP: Logged Jim Bedford Jedi Master Film Handler Posts: 597 From: Telluride, CO, USA (733 mi. WNW of Rockwall, TX but it seems much, much longer) Registered: Jun 99 posted 05-02-2008 01:45 PM                        Although I'm sure Frank is loaded with Vitamin C (definition of ascorbic"), I'm sure he means "acerbic" (acid in temper, mood, or tone), which fits me as well sometimes. As far as the non-blow-hards we've been discussing, would any try to run a vehicle without a fan or fanbelt? It's the same freakin' thing.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-02-2008 03:12 PM                        Remember, guys, that ozone is inherently unstable. If you store it for awhile in a crawl space, for example, O3 becomes O2 (oxygen.) Louis [ 05-02-2008, 08:37 PM: Message edited by: Louis Bornwasser ]  |  IP: Logged
