The problem with exhausting outside is the loss of heated or cooled air in your shop.
Venting cyclone dust collector outside.

Hi all i have a good oneida cyclone collection system in the shop.
Wrestling the canister out of the upper housing and manu.
Sometimes though an indoor dust collector has no vent to the outside.
Even huge dust collector fine filters quickly plug at this airflow so the best solution is to put all dust collectors outside and use the far less expensive more open filters that freely pass the 30 micron and smaller airborne particles.
What s important however is that venting outside directly will put the fine particule matter right next to where you are breathing.
They also provide particulate retention which means that no particles or flaming.
Venting outside requires makeup air that should be at least twice the diameter as the outlet duct.
The choke point literally is the fine dust filter.
The dust collector takes air from in the room and blows it into the bags.
I currently have it mounted to a thrown together cart that gets in the way and takes up too much space my shop occupies 2 3 of my 3 car.
In that case you don t need to enclose the area below since the chip collector is sealed and the air has a direct path back to the shop.
If you live somewhere where you enjoy having the room heated or cooled moving the bags outside will defeat your heater or cooler.
Nfpa 68 allows this as long as the ductwork is strong enough to withstand the potential damage.
Almost all of the stationary machines are ducted via 4 hoses.

Venting dust collector outside sign in to follow this.
In this case you have an option but not a cheap one.
Most of the waste goes in a container underneath the cyclone and the exhaust air containing some very fine dust can be routed to a filter or directly to the outdoors.
Dust collectors located indoors usually have ductwork that vents to the outdoors.
Flameless explosion vents as the nfpa defines them act as flame arrestors completely stopping flames.
The blower is powerful enough that it s going to pull replacement air from somewhere.
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.
But you will have to plan on how that air gets replaced.
Totally isolating the de from the work area and venting outside is about the best thing you can do.
The cyclone is outside but the dc fan discharges into filter bags located back in your shop.
I have a the cheap hf dust collector with a super dust deputy dumping into a 55 gallon plastic barrel.
If you move the bags outside it will pump air from the room to outside.
They can function just like you describe.
A filter really is not that expensive.
