Venting dust collector outside.

Flameless explosion vents as the nfpa defines them act as flame arrestors completely stopping flames. Flameless venting can consist of a flame arrestor element vent panel and flanged housing. Nfpa 68 allows this as long as the ductwork is strong enough to withstand the potential damage. 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 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. Sometimes though an indoor dust collector has no vent to the outside. This method is designed to combine the techniques of explosion venting and flame arresting. If you vent to the outside you will get the best air quality possible.

If you live somewhere where you enjoy having the room heated or cooled moving the bags outside will defeat your heater or cooler. What s important however is that venting outside directly will put the fine particule matter right next to where you are breathing. The blower is powerful enough that it s going to pull replacement air from somewhere. The dust collector takes air from in the room and blows it into the bags.

Explosion vents are commonly used on baghouses and cartridge dust collectors. If you move the bags outside it will pump air from the room to outside. Totally isolating the de from the work area and venting outside is about the best thing you can do. In this case you have an option but not a cheap one.
