Ventilation for Soldering Lab
Ventilation for Soldering Lab
(OP)
A local tech academy we do some work for ask us to provide a rough budget price for a new soldering/brazing lab they are thinking of installing in the future. We're an HVAC contractor. They will end up hiring an engineer but were just looking for some rough numbers to get into their budget.
They will have 16 students with 16 areas that they will practice soldering.
Talking to the current instructor, they would set up some pipe and fittings on a metal bench and practice soldering. The soldering isn't constant. According to the instructor they may solder an hour or two in the room per day.
Was thinking of a roof mounted exhaust fan with exposed spiral to a small sheetmetal hood mounted above the 16 locations where the kids will solder.
Fan would be interlocked with a roof mounted 100% MUA unit. Unit would be undersized to keep the space in a negative pressure.
When the exhaust system is off, the space would be heat/cooled by either a packaged rooftop or a couple of ceiling suspended ductless heat pumps.
Not sure if this type of system would be fine or would they need a dust collection system instead?
Also, I couldn't find any ventilation requirements or heat loads for this type of room. Found things on welding labs but not sure if this would be the same.

RE: Ventilation for Soldering Lab
Now for a quick reference to ventilate soldering stations, I recommend "Ventilation for control of the work environment by WA Burgess, MJ Ellenbecker, RD Treitman" Amazon has it for about $133 but you may be able to get it from other book dealers such as Abebooks.com for a lesser price. This book has numerous designs on ventilating hoods such as canopy types, slot types and exterior hoods which can be moved around as closely as possible to the soldering stations. Duct design for branch connection to trunk lines and motor/exhaust fan sizing is included in this book.
