Venting Dust Collector Outside

If you move the bags outside it will pump air from the room to outside.

In this case you have an option but not a cheap one. If you live somewhere where you enjoy having the room heated or cooled moving the bags outside will defeat your heater or cooler. Flameless venting can consist of a flame arrestor element vent panel and flanged housing. If it can t pull replacement air you create a backflow restriction on the blower and risk reducing the overall air flow of the unit.

Dust collectors located indoors usually have ductwork that vents to the outdoors. They also provide particulate retention which means that no particles or flaming. Totally isolating the de from the work area and venting outside is about the best thing you can do. You will either suck it in again through the air inlet or have it ninja through an open window or breathe it in when you go outside.

The blower is powerful enough that it s going to pull replacement air from somewhere. This method is designed to combine the techniques of explosion venting and flame arresting. Nfpa 68 allows this as long as the ductwork is strong enough to withstand the potential damage. The dust collector takes air from in the room and blows it into the bags.

Flameless explosion vents as the nfpa defines them act as flame arrestors completely stopping flames. But you will have to plan on how that air gets replaced. The only proviso when venting outside is make sure the vented air is not near any open doors windows etc that are open to replace the air that is being extracted otherwise the dust can be returned into the workshop. What s important however is that venting outside directly will put the fine particule matter right next to where you are breathing.
