6″ Window Exhaust Port

Description

6 inch window vent port for miner exhaust

A 6 inch window vent port is the part that finally gets the heat out of the room. Everything upstream of it — the shroud, the elbows, the trunk — only matters if the run actually terminates outside the building. The usual improvised ending, a length of flex duct wedged under a cracked sash, lets almost as much air back in as it pushes out, whistles, and falls out of the window the first time somebody closes it.

This is a proper termination: a flanged plate with a 6-inch collar on the inside face, a gasket groove around the flange so the seal has somewhere to sit, and retention on the outer face for an insect screen. It mounts through a panel and it stays where you put it. Front to back the whole body is 39 mm, so the port sits tight against the panel instead of standing off it — on a sliding window that is the difference between a sash that closes onto the panel and one that will not.

Drawn in-house for the people who mine in the room they live in — apartments, basements, garages, spare bedrooms — where the exhaust has to be dealt with properly and the building cannot be modified.

What it fits, and what it mounts into

Standard 6-inch duct on the inside collar, rigid or flexible. The outside is a flanged face designed to mount through a panel: plywood, acrylic or rigid foam board cut to fill a sliding window opening is the classic renter-friendly approach, and a permanent wall penetration works exactly the same way.

If your trunk is 8-inch, terminate it at 8-inch with the 8″ Window Exhaust Port rather than reducing at the wall. If the last section into the port is flex duct and you would rather have a collar drawn specifically for it, there is the 6-Inch Flex Duct Window Vent Port. And if the duct reaching the window is 8-inch but the panel opening is not, the 8″ to 6″ Duct Reducer goes immediately before this part.

How it installs in a window

1. Cut a filler panel to the shape of the open sash — plywood, acrylic or rigid foam.
2. Cut a hole in the panel for the port body and mount the port through it, flange outboard.
3. Seat a gasket or foam strip in the flange groove and fix the panel into the window opening.
4. Fit the insect screen to the outer face.
5. Clamp the 6-inch duct to the inside collar.

The window itself is untouched, and the whole assembly lifts out in one piece when the season changes or the lease ends.

Why the termination decides whether the run works

A duct hanging out of a gap is not a closed system. Warm exhaust leaves through the top of the gap while room air is pulled back in around the bottom, which is why an unsealed window setup can run all day and never really cool the room. Sealing the opening with a panel and giving the exhaust one defined exit turns the run into an actual one-way path out of the building. The gasket groove is there so that seal survives being taken apart and put back, and the screen retention is there because an open 6-inch hole facing a garden is an invitation.

• Seals the opening so exhaust leaves without room air being drawn back in
• Carries a gasket groove in the flange for a seal that survives reassembly
• Retains an insect screen on the outer face
• Mounts through a removable filler panel, leaving the window unmodified
• Works equally as an intake port to feed a machine outside air

Open source — because venting a miner should not be a paid secret

D-Central Technologies designed this port — the flange, the gasket groove, the screen retention — and publishes it open source under CC BY-SA 4.0 at the 3D models download center: free to download, modify, remix, print and sell. Its card is the 6″ window exhaust port model. Window ports get modified a lot, because every window opening is a different shape, and that is a good reason for our geometry to be in your hands as well as ours.

The download is window_port_6in.zip: STL, CC BY-SA 4.0 licence, and the installation and safety guide. This listing is the finished port, made to order in PETG — black if you want it to disappear into the window, orange if you want it to look like ours — and shipped from Montreal, Quebec, with the collar cut to the same standard as every other 6-inch fitting in the line. The file is free and stays free; the printed part, or D-Central’s fund page, is what funds the next design.
