When considering the installation of a home elevator, one question that often arises is: What happens during a power outage?
For homeowners who live in areas prone to storms, blackouts, or grid instability, elevator safety during a power failure can be a deciding factor. Fortunately, pneumatic elevators offer a highly reliable and safe solution even in the absence of power.
Differing from traditional elevators, pneumatic elevators do not rely on complex pulley systems or heavy counterweights. Instead, they use air pressure to move the cab between floors, which gives them a unique advantage when power is interrupted.
With their self-lowering design and built-in safety features, these elevators are engineered to prioritize passenger safety above all else.
In this blog, we’ll explore how pneumatic elevators work, what exactly happens when the power goes out, and why they’re considered one of the safest home elevator options available today.
We’ll also touch on important features like emergency communication, lighting, and certifications that make these systems suitable for all types of homeowners—including older adults and those with mobility challenges.

How Pneumatic Elevators Work
Pneumatic elevators, also known as vacuum elevators, operate using a patented air pressure system that allows the cab to travel vertically without the need for cables or pulleys.
Instead, the elevator uses differences in atmospheric pressure to move the cab smoothly up and down. When ascending, the system removes air from above the cab to create lift.
To descend, air is released back into the chamber, and gravity takes over—allowing the cab to lower gently and efficiently.
Because the elevator system relies on air pressure rather than traditional motors or mechanical parts, it uses significantly less energy. In fact, energy is only used during the ascent.
Descent requires no electricity at all, which is part of what makes pneumatic elevators so efficient and eco-friendly. This low-power design also plays a crucial role during power outages.
From a structural standpoint, pneumatic elevators require minimal space and don’t need a machine room, pit, or hoistway.
This makes them ideal for retrofitting into existing homes or adding to new builds with limited square footage.
In addition to their efficient operation, these elevators are visually sleek and modern. Their transparent cylindrical design often becomes a centerpiece of the home, combining form and function in a way that traditional elevators rarely do.
What Happens to Pneumatic Elevators During a Power Outage?
This is where pneumatic elevators truly shine. When a power outage occurs, most homeowners worry about getting stuck mid-floor and needing to call emergency services.
But with pneumatic elevators, that concern is virtually eliminated.
These systems are designed to use gravity and air pressure to descend safely to the ground floor when power is lost.
Because the elevator cab is lifted using suction (a vacuum created above it), once the power cuts out, the system releases air back into the chamber, equalizing the pressure.
As a result, the cab gently lowers itself to the bottom level without requiring manual intervention or electrical power. This feature is not only convenient—it’s also a huge safety advantage.
No one likes the idea of being trapped in a tight space, especially during a blackout. But pneumatic elevators are engineered with fail-safes to ensure peace of mind.
You won’t find yourself suspended between floors or waiting for a technician. For most single-family homes, no manual rescue is required at all.
Additionally, these elevators are equipped with emergency brake systems and locking mechanisms to prevent uncontrolled movement.
Many also come with battery-powered lighting and ventilation, so even if you’re descending in the dark, you’ll remain safe and comfortable.

Built-In Safety Features Homeowners Can Trust
When investing in a home elevator, safety should always be top of mind. Pneumatic elevators are not only known for their innovative design but also for their built-in safety systems that ensure user protection in any situation—including power outages. These features are especially beneficial for households with seniors, children, or people with mobility issues.
First, all pneumatic elevator models come with mechanical brakes and safety locks that activate automatically in the event of any system failure. These physical mechanisms serve as a backup to the air pressure system and prevent any unintended movement of the cab.
Second, the elevators are fitted with emergency communication systems, allowing passengers to alert someone in the home if needed.
While the system’s automatic descent usually makes this unnecessary, it’s a comforting feature for users who might be anxious about being in an enclosed space during a blackout.
Third, lighting and ventilation systems powered by backup batteries provide added assurance. Even in the dark, the cab remains illuminated and breathable, minimizing discomfort and enhancing visibility until the rider exits safely.
Pneumatic elevators are also fully certified under industry safety standards, including ASME A17.7/CSA B44.7.
These standards are put in place to regulate the design, construction, installation, operation, and maintenance of elevator systems—so you can trust that the product meets the highest levels of safety and reliability.
These layers of protection are why pneumatic elevators are frequently recommended for residential use.
Whether you live alone or with loved ones who may need assistance, you can rest assured that your home elevator system is equipped to keep everyone safe—even when the power goes out.
Conclusion: Peace of Mind When the Power Goes Out
When it comes to home elevators, safety isn’t just a feature—it’s a necessity.
Pneumatic elevators offer a reliable, innovative solution that not only enhances your home’s accessibility and design but also ensures your safety during emergencies like power outages.
Thanks to their air-driven technology, automatic descent feature, and robust safety mechanisms, you can feel confident knowing that you or your loved ones won’t be left stranded if the lights go out.
Whether you’re planning ahead for aging in place, upgrading your home’s accessibility, or simply looking for a stylish, space-saving lift, pneumatic elevators are a smart, secure investment.
And unlike traditional systems, they work with gravity—not against it—giving you peace of mind when the unexpected happens.
