| We are installing a new reflow oven and I have been told that we do not need to vent the exhaust out through the roof since we have a false ceiling. All that is required is to vent above the false ceiling and that the air exchange is great enough t

| You may want to rethink using an inline for both OA and No-Clean applications. Since the majority of your applications are OA, it would not make a lot of economic sense to run saponifier in your inline for a minority application. My suggestion is
