When searching for a dryer vent connection, you may have run across the periscope dryer vent. Also known as a slim duct, a periscope connection is an effective way of venting hot moisture from your dryer. There are advantages and drawbacks to having a periscope dryer vent. For one, periscope dryer vents are not suited for every home. The space in which your dryer is located will greatly determine if it’s right for you. If the dryer space doesn’t fit the vent’s needs, you may need a semi-rigid duct or a metal foil duct.
The Need for a Periscope Dryer Vent
Periscope dryer vents are best suited for smaller or cramped areas. Those with minimal space between the dryer and wall will benefit from a periscope duct. A standard foil tube would get crushed from the dryer resulting in a less effective duct. A periscope cut can be installed vertically, horizontally, or diagonally giving it versatility in tight spaces. On average, most periscope dryer vents range from 27 inches to 48 inches. The duct can also be adjusted so you can get the best fit from the dyer to the outside.
Those with a duct above their dryer, either further up the wall or in the ceiling, will not be able to use the periscope dryer vent. Instead, a semi-rigid or rigid dryer vent is the best option. You should also avoid a periscope dryer vent if you have room for a standard duct. Periscope ducts are known as slim ducts for a reason. They are designed to be used by those who have smaller spaces for their dryers.

Advantages of Periscope Dryer Vents
If you are able to use a periscope dryer vent, then you’ll see drastic advantages. Many dryers use aluminum foil tubing with numerous ridges. Each ridge adds to the entire duct’s surface area, which slows down the air escaping the dryer. As a result, the dryer works less efficiently, and it may take you multiple cycles to dry your clothes entirely.
With the periscope dryer vent, air reaches the outside faster because of the shorter space the air must travel. Additionally, slim ducts are made of smooth metal, so air passes through it more efficiently than any rigid foil tube. The smooth surface also reduces the chance of lint buildup.
Finally, the cleaning process is significantly easier with a periscope dryer vent. When you have your dryer vent cleaning every year, the process will be faster than a longer duct.
Disadvantages of Periscope Dryer Vents
The major disadvantage of periscope dryer vents is they are not suited for every home. These vents are built for small, cramped, and tight spaces. A periscope duct can be installed within two inches of space, which makes it perfect for cramped areas.
The only other disadvantage of a periscope dryer duct is you can’t just buy any brand. Certain brands are built for specific dryer models. Consult your dryer manufacturer’s website to learn more about the types of slim ducts they support or produce.
