Is your exhaust duct connected to a reflow oven that is used for flux? The condensate may be carring over from another oven that shares the same duct.

It does specify when to clean. But when we open it up, there's not much flux in the containment. The containment doesnt seem to trap the flux. infact, we hv more flux in the duct than the containment. anyway, we will talk to MFGR to get their rec

OK great! Seems like there's (mostly) a consensus on the ducting outside, and it seems like the multiple units to one duct is doable. What are you thoughts on the floorplan/layout then?

I use Kyzen's Aquanox SSA cleaner in a heated parts cleaning tub to clean anything with flux condensate on it. When heated to 120F, the stuff melts away like ice under hot water. When the cleaning solution is loaded, I send it in an evaporator. The s

I have a severe problem with flux residue being drawn up the vent ducts of my reflow oven. This residue reaches a critical mass then begins to flow down the ducts and becomes very messy. I run a no-clean process and use IR oven. Has anyone else out

Ken; my experience has been that eventually the flux builds up in the vents and then drips back down on the boards. For a simple oven with an air cooler the flux must go somewhere. Better in the ducts than in the oven. Just replace the ducts every ye

Hi, There are a couple of Omniflow 7 and 7E that are being used in the production. Recently we found a lot of flux clogging up the exhaust ducts. Anybody who uses the same type of tool who has seen this kind of problem? How can we fix this? Does

Please read your manual, I am sure that it will address proper maintenance of your oven ducting and flux build up. The MFGR will also be able to specifically address your problem and let you know if any upgrades are available. Flux collection filter

Are you sure your units are correct? Is this in the exhaust duct or actually in the reflow area? 4000 FPM = 67 FPS or 45 MPH (73 km/H). I have no doubt such a wind would blow larger parts off the board. If this is only in the exhaust ducting, the

This is ducting air speed. Please advise on how to obtain reflow air speed. Our measurement tool is a Dwyer No. 460 Air Meter (max. 4000 FPM, accuracy of 10 FPM).We are using 8 inch ducting. Thank you for you help thus far. Puvendran
