Venting Dust Collector Outside

The dust collector takes air from in the room and blows it into the bags.

Venting dust collector outside.

Totally isolating the de from the work area and venting outside is about the best thing you can do. Sometimes though an indoor dust collector has no vent to the outside. Flameless venting can consist of a flame arrestor element vent panel and flanged housing. But you will have to plan on how that air gets replaced.

The blower is powerful enough that it s going to pull replacement air from somewhere. Flameless explosion vents as the nfpa defines them act as flame arrestors completely stopping flames. If you vent to the outside you will get the best air quality possible. This method is designed to combine the techniques of explosion venting and flame arresting.

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. Nfpa 68 allows this as long as the ductwork is strong enough to withstand the potential damage. 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.

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. If you move the bags outside it will pump air from the room to outside. Explosion vents are commonly used on baghouses and cartridge dust collectors.
