Most asked questions about Mark 2 portable AC exhaust system
How is heat being removed through the Mark 2 AC?
With dual hose venting heat system, the heat is removed from inside to outside through Mark 2 AC. One hose takes in the outside air, then the air flows across the condenser. The heat is transferred to the refrigerant and finally released into the outside air through another hose. The best way to cool down a limited space is to connect the two hoses and separate them slightly outside of the window or outside the door. Both are in the Mark 2 box.
What is the dual hose system?
ZERO BREEZE had integrated a revolutionary dual hose system to draw in fresh outside air and output the hot exhaust air through another hose. Dual Hose allows an intake hose to be used to circulate fresh air inside. No negative pressure in the room. And it provides better performance and maximizes output cooling power.
How to set up the hoses in the window?
The Mark 2 battery package includes two foam adapters. So if you order the battery, you can use the foam adapter to extend the hoses to the outside.

Does the ac run on electric as well as battery
Hi @Linda Marie, In general, it’s more efficient to have both an intake and exhaust system for proper ventilation in a small space like a camper van. This allows for a continuous flow of fresh air into the space, while removing stale air and excess moisture.
If you only run the exhaust fan and don’t have an intake system, you may create negative pressure in the van, which can draw in air from undesirable sources like through cracks or vents in the floor or walls. This can also make it harder for the exhaust fan to remove all the stale air and moisture from the van.
Hi @Cedric Green, hope this blog helps you.

Hi @Eric, in general, it’s more efficient to have both an intake and exhaust system for proper ventilation in a small space like a Sprinter van. This allows for a continuous flow of fresh air into the space, while removing stale air and excess moisture.
If you only run the exhaust fan and don’t have an intake system, you may create negative pressure in the van, which can draw in air from undesirable sources like through cracks or vents in the floor or walls.

Having a separate vented fan on the roof can help remove hot air, but it’s important to ensure that the fan is positioned in a way that it doesn’t interfere with the operation of the intake and exhaust fans. It’s also important to consider the placement of the roof fan to ensure that it doesn’t create additional negative pressure or air turbulence in the van.
In summary, it’s best to have a well-designed ventilation system that includes both intake and exhaust fans, along with any additional fans or vents needed to address specific ventilation needs, such as removing hot air.
I live in Texas and last Summer I used it in my small camper. When the outside temperature is quite hot I leave the intake hose pulling the cooler air from inside. My thought is that the unit can cool that air down easier. Is that reasoning correct?
