When you are venting through a screen, the hot outtake airflow will definitely come across some sort of resistance. If the screens are made of mesh, there will be plenty of space for the airflow to pass. If the mash doesn’t provide empty space, then it’s definitely not possible to pass air through it. On the other hand, if the mesh is made of nylon, we discourage venting portable air conditioners through it. Nylon is highly susceptible to heat, which means it’ll get damaged over time. So, you should try this only if you have a steel screen.

This is not the efficient or ideal way to vent a portable air conditioner. In fact, it’s far from being efficient. There are certain methods that can help to increase and even maximize the airflow.

Way to Maximize the Airflow When Venting through a screen

Sliding the screen to create an opening to vent through the screen is not an option. By doing this, it will destroy the purpose of the screen. And moreover, it will help bugs and other outer objects to enter the room easily through it. 

So, we are presenting three methods below here to help you to know how to maximize the airflow when venting through a screen :

  • Most people adjust the exhaust in such a way that the air passes directly through the screen. As long as you maintain it and wash it regularly, it will function properly. As the air will pass through the screen frequently, the screen will need your extra cautiousness to keep it clean and maintained whenever it catches dust and dirt constantly.

If you maintain it, it will never decrease the airflow through the screen. The best way to spot whether the screen is dirty or not is by checking whether you can see through the screen or not. In general, you need to clean the mash at least once a month, but if you can check weekly, it would be a better situation. 

Another thing you need to keep in mind is the type of screen you are using for venting. Basically, the thin screen is always better to vent a portable air conditioner. You’llYou’ll face no more problems with the thin screen than the widescreen. 

  • There is another way by which it will not only reduce the amount of maintenance but will also help you to increase and maximize the airflow. For this, you need to cut plywoods as wide as the exhaust tube of the portable air conditioner. Once you get the width right, measure the height of the screen and match the cut plywood height with it. 

Attaching the plywood with the screen will create a new surface on the side where the screen closes. Then you’ll have to measure the diameter of the exhaust tube and cut a hole in the plywood. Route the tube through the hole in the plywood, and now you have a perfect exhaust system that will allow you to vent your portable air conditioner without any worries.

The best part of this method is that it doesn’t require any maintenance, and there won’t be any loss of airflow either. This will help your portable air conditioner from overheating, and it will also provide cool and moisture-free air to your room.

  • By purchasing aftermarket, add-ons are another way of maximizing the airflow. There are various add-ons that can increase the effectiveness of the exhaust tube, and these can easily be used. 

Before purchasing, you need to know certain things, and you need to know how much airflow the screen is reducing. Suppose if you find the mesh is blocking 50% of the airflow of the exhaust compared to holes without any resistance, you need to get yourself an extension that can increase the exhaust area up to 200%. This is how it will help you to counter the resistance and to maintain the maximum airflow.
