You can use one but over spec it. It will be a non-linear problem to figure out how much each exhaust port exhausts. Also have lots of shut off valves to shut off exhaust ports that you are not using. We have some holes in the walls in the back of th

What substances are emmitted when exhausting standard glue cure? Thanks, Robert

If you calculate CFM using the numbers you have provided you are pulling 1396CFM out of the oven. I am not sure what Hellers spec is but I know a Speedline OmniExcel Air machine should be set at 300CFM. I do know for a fact that to much exhaust can s

Did you just change anything on the Exhaust?... even if the change was adding something else to the main exhaust trunk, if you don't have each item seperated. Although CFM changes should not effect the Blower Speeds or the Zone stablizing time, since

Our Heller oven is functioning well. However, we see defects from the oven, such as shifted coil inductor components, and missing chip components from time to time. When we re-scan the board at the AOI, the defect was not present at that stage,hence

slowing-down the conveyor to allow the solder to heat these balls more. But that may not be the answer, because if the flux is exhausted, more heat will not help. Then if the flux is exhausted, the answer is to crank the belt. Two different answer

Hi, What will be the effect in my soldering if my Reflow Oven's Exhaust system is not properly extracting air from the chamber. Recommended is 100 CFM but I am measuring 45 CFM. thanks,

Don't forget about the exhaust. To keep the room at a positive pressure you must add more air than the exhaust from ovens and waves removes.

Here is another visual. http://www.metacafe.com/watch/416435/computer_fan_generator/ Only issue with a PC fan is I'm positive that the blades will melt while enduring the heat of the reflow oven exhaust.

You can do what someone at heller mentioned to me to check if the exhaust is working properly. Take a baseball cap place it by the opening to the vent and if it wants to suck in the hat your good to go. Cost $12.00
