Four-piece magnetic screen window external exhaust vent

Note: What I marked in the print file is the outer diameter of the model's interface itself, not the inner diameter of the hose or duct, because pipe tolerances vary among manufacturers (for example, the 80mm pipe I bought actually had an 83mm inner diameter)

Optional Window Screen Positioning Tabs:

• Mode 1 Two-piece mode: You can directly fix two [Duct Port Parts] across the window screen, and connect a section of pipe outside to prevent dirty air from being blown back by the wind
• Mode 2 Three-piece mode: You can screw the [Base Part] and one side's [Duct Port Part] onto the screen window for fixing, and magnetically attach the [Duct Port Part] on the other side
• Mode 3 Four-piece mode: Permanently fix two [Base Parts] with fixing grooves onto the window screen, and then simply magnetically attach the [Duct Port Part] each time With the fixing ring, it is not easy to slide

Optional 3 Fixing Methods:

• Magnetic (8x2 magnets), 8 magnets for the two-piece mode, 16 for the four-piece mode Adjustable magnetic force, up to 32 magnets can be installed
• Wire (06mm diameter, commonly used for tying electrical wires), pass through the reserved holes and tie directly Wire grooves are already provided on the [Base Part] For aesthetics of the [Duct Port Part], if wire fixing is needed, you will need to manually pierce the wire holes
• Screw (2x10 self-tapping) fixing

Other Details:

• The magnet holder is designed with two removal holes; magnets can be pried out with scissors These two holes are thin and can also be pierced to tie wires
• The outer edge of the duct port is raised to prevent the pipe from slipping off

How to Choose Duct Diameter:

• The larger the pipe, the lower the noise and the smaller the wind resistance
• 80mm and 100mm are common sizes for indoor bathroom heaters and exhaust fans; that kind of aluminum foil duct is very cheap
• Nylon steel wire ducts come in all sizes, such as 50/60/75/80/100, and are relatively expensive
