Top 5 Automatic Vent Openers
1. Gigavent – Best For Heavy Duty Use
This one is the largest and strongest vent opener in the market. If you have to lift very large and heavy vents greenhouse windows then this is the device that you should go for.
What amazed us more was the damper and other springs that allows it to remain open even with strong gusty winds. Lastly, the construction is great and made out of black and silver heavy-duty metal. You can make it work along with the power grid for independent monitoring of temperature.
- Extremely sturdy construction
- Can lift heavy weight
- Works both for homemade greenhouse or the professional ones
- Can endure low and high temperatures in both
- We didn’t find any
Bottom Line
Gigavent is the best for greenhouse vent kits or any heavy cold frames. Further, it comes with easy height adjusting and mounting customization.
2. Palram – Best For Roof
This auto vent kit is best designed for rooftop vents. Nevertheless, you can use it for any windows or cold frames too. The product fits best to Palram greenhouses but you can also consider it for your homemade greenhouse if it fits your requirement.
The only glitch we found was in the design. The design is great but if it would allow to readily detach and re-attach without removing the bolts/screws it would be better.
- Easy installation
- Can adjust to a temperature well
- Best for roof vents
- Fits to all the standard greenhouse vent kits
- Screws need to be removed for detaching and reattaching
Bottom Line
A great automatic vent opener that runs on oil. We recommend this one especially for the roof top vents.
3. Univent – Best For Light Windows
Univent is yet another powerful and compact vent opener. It is best recommended for light windows on the rooftop or in the house that requires temperature control.
Our tests suggest that it can be installed in greenhouse windows, cold frames, and operating sliding doors. The only thing that you need to take care is about the weight limit, it can only lift up to 15 lbs weight. So, prefer installing it in windows only. Lastly, you get univent automatic vent opener replacement cylinders in the market. So, in case the device stops responding to temperature changes you can simply replace the cylinder and make it as good as new.
- Good for door and windows
- No installation
- Compact user-friendly design
- Cannot be installed on roof
- Cannot lift heavy windows
Bottom Line
A decent product meant for lightly weighted windows and doors.
4. Vent-L – Best For Very Heavy Windows
This one is another powerful and strong vent opener in the market. You should consider buying it if you have extremely heavy windows to lift. Majorly, this vent opener is used for commercial or big greenhouses with extra-large windows. You can lift as heavy as 100kgs of weight.
The good part is Vent-L is not an electric greenhouse vent opener instead it exclusively operates on the temperature fluctuations of the greenhouse. The only glitch we found was the width of the opener. The small width with an aluminum screw base tends to reduce the overall sturdiness which for sure is a downside.
- Can lift extremely heavy weight windows and doors
- Spring is smooth
- Can adjust the temperature as per the greenhouse
- The make and design is not great
Bottom Line
A good product for lifting as heavy as 100kg windows or doors. This device is meant majorly for large commercial greenhouses and not for homemade ones.
5. Wiwir – Best For Budget Conscious Users
If you are looking for automatic vent openers with good quality and budget-friendly prices then this can be the one.
Lastly, the product has a quality construction made from anodized aluminum. This kind of material is good for places with temperatures less than 40 degrees.
- Solar-powered
- Temperature control is good
- Inexpensive
- Good construction
- Can’t withstand high temperature
Bottom Line
A budget-friendly automatic vent opener for windows and doors which uses energy from sun and air to operate.
Things To Consider
Buying a vent opener can be confusing after looking at the available options. All the openers come with the same idea of opening windows and doors as per the temperature requirement. But to check their effectiveness and you need to test them which is quite impossible for you.
To ease up your task we have tested the best of the best ones and then jotted a buying guide that tells about the important requisites. The buying guide will help you choose the one that fits your requirement. So, prefer going through it before choosing any.
1. Capacity
This refers to the weight they can lift. These vent openers vary in capacity. Some can lift up to 15 lbs only and some can lift as high as 25olbs of weight. So, it’s better to buy one that fits your capacity. We suggest you measure your load capacity before choosing anyone. If you have light windows or doors to open, the models that you should consider are Univent and Wiwir . If you have moderately heavy windows or door consider buying Gigavent and Palram . And if your windows are extremely heavy, consider buying Vent-L .
2. Construction
This is again an important requisite. As they are meant to open windows or doors automatically so a good construction is a must. Without this, the product might break or not work effectively as per the need. Metal or aluminum construction is a good choice for automatic vent openers. Any material apart from this is not feasible as it might wear off quickly.
Furthermore, also pay attention to the spring and hydraulic oil cylinder. The spring in them should be smooth and flexible for easy opening and closing. The hydraulic cylinder should be filled with oil and it is important for the greenhouse vent opener cylinders to be replaceable.
It is because with time they tend to lose their temperature sensitivity. So, to bring them back to the life you need to replace their cylinders. That is why vent openers that have replaceable cylinders are always recommended.
3. Temperature Range
This is again important. An automatic vent opener closes or opens the windows after hitting a certain threshold requirement. It frees you from the hassle of opening or closing the windows with the change in temperature. These devices have a threshold value i.e temperature which guides them open or close as pr the need.
The plants or the place where they are installed are required to be at a set temperature and these openers are to be open or close with temperature fluctuations. Any product that fails to respond to hot or cool temperatures is not a good fit. For the same reason, we have only included the products that are very effective against temperature fluctuations.
