Diesel Exhaust Question

Diesel Exhaust Question

Diesel Exhaust Question

(OP)
I would like to use a cartridge-type dust collector to clean the air in a mining maintenance facility where the contaminants are a mixture of welding smoke and diesel exhaust.  I was wondering if anyone had any experience with this sort of application.  I am worried about the diesel exhaust being oily enough to bind up the filters and prevent them from cleaning properly.

We have enough direct venting and make-up air to prevent carbon monoxide buildup, but we would like to move more air without a huge increase in heating costs.

Any advice would be appreciated.

Someone started the thread above. didn't take too far.
Localized exhaust is the way to go. Remove the fumes directly form the engine' tail paipes. The welding exhaust should have its own "snorkel" metal flex swinging away from the welding table interloaked with a make-up damper or supply fan.
All these will work intermitently with some diversity so you don't have to bring in excessive amounts of OA.
If your space is large, consider an Heat recovery Ventilator, it'll pay for itself in less than 2 years.

I've seen those cartridges recirculating air, the filters are so expensive that they never get replaced.

Hope other will carry your thread farther with more ideas.
