Lab 808 Window Vent Cassette

Use the Vent Cassette and any ventilation system at your own risk! I can't test uses or scenarios other than my own setup. If you're venting air from a 3D printer or anything generating fumes, make sure the exhaust fan is strong enough to maintain negative pressure throughout the duct inside your home. Be careful with any helper fans along your ducting system because if they're too powerful they can create positive pressure. This is even more likely because of the Vent Cassette's restrictiveness. Positive pressure will lead to air leaks. Also make sure the fan's exit side is sealed tightly to the Vent Cassette and make sure the lid is tightly sealed to the box. Use silicone adhesive if needed. No matter how well you design and build your system, air can be unpredictable and you might still end up with leaks. Always test and take proper precautions! The goal with this project was to exhaust air from my P1S out of a typical sliding window but with a minimal opening size to minimize outsi
