Introduction
Home elevators at Airo are designed and programmed considering usage by elderly and children. Safety is not an afterthought — it is the foundation upon which every Airo vacuum elevator is built. Our Health, Safety, and Environment (HSE) policy ensures that every unit leaving our facility meets the highest standards of passenger protection.
The Airo vacuum elevator incorporates five distinct layers of safety, each designed to address a specific scenario that could potentially arise during operation. These layers work independently and in combination to ensure that passengers are always protected, regardless of the situation.
Layer 1: Power Failure During Operation
Scenario: The electricity supply is interrupted while the elevator cabin is in motion between floors.
How Airo Handles It:
When a power failure occurs while the cabin is in transit, the emergency air valve system activates automatically. This valve allows atmospheric air to enter the tube above the cabin in a controlled manner. As the air pressure equalises, the cabin descends gently and smoothly to the nearest floor below under the influence of gravity.
This descent is entirely mechanical and requires no electrical power whatsoever. The cabin comes to rest at the floor level, and the door can be opened normally, allowing the passenger to exit safely.
Key Point: The passenger experiences a gentle, controlled descent — not a sudden stop or freefall. The ride down feels similar to a normal descent, just slightly slower.
Layer 2: Power Failure at Floor Level
Scenario: The electricity supply is interrupted while the elevator cabin is stationary at a floor landing.
How Airo Handles It:
If the cabin is already at a floor level when power is lost, the situation is straightforward. The cabin door lock operates on a mechanical latch system that can be released from inside the cabin without electrical power. The passenger simply opens the door and steps out.
Additionally, the cabin’s position at a floor level means it is already aligned and stable. There is no movement to manage, and the passenger can exit immediately and safely.
Key Point: Passengers are never trapped inside the cabin during a power failure when the elevator is at a floor landing.
Layer 3: Rescue from Within the Cabin
Scenario: A passenger needs to initiate their own rescue from inside the cabin, such as during an extended power outage or if they feel unwell.
How Airo Handles It:
Inside the Airo vacuum elevator cabin, there is a clearly marked emergency release mechanism. This allows the passenger to manually initiate a controlled descent to the nearest floor below. The mechanism works by releasing a small amount of air pressure in a regulated manner, allowing the cabin to descend gently.
The in-cabin alarm button can also be activated to alert other members of the household that assistance is needed. The alarm is powered by a backup battery and will sound even during a complete power failure.
Once the cabin reaches the nearest floor, the passenger can use the manual door release to open the cabin door and exit safely.
Key Point: Even without external help, a passenger can bring the cabin to a floor level and exit independently.
Layer 4a: Rescue from Outside — Power ON
Scenario: A passenger is inside the cabin and needs assistance, but the building’s electrical power is available. Someone outside the elevator initiates the rescue.
How Airo Handles It:
When power is available, an authorised person outside the elevator can use the external control panel to bring the cabin to a specific floor. The elevator’s standard controls function normally, allowing the cabin to be moved to the nearest or most accessible floor. Once the cabin is at floor level, the landing door can be opened to assist the passenger in exiting.
The process is identical to normal elevator operation, just initiated from outside the cabin rather than from within.
Key Point: With power available, rescuing a passenger from outside is as simple as calling the elevator to a floor.
Layer 4b: Rescue from Outside — Power OFF
Scenario: A passenger is inside the cabin, there is no electrical power, and someone outside the elevator needs to perform a rescue.
How Airo Handles It:
In this scenario, the rescue procedure involves manually releasing the air valve from outside the elevator tube. The external air release mechanism is clearly marked and accessible at the top of the elevator unit. When activated, it allows air to enter the tube above the cabin, causing a gradual, controlled descent to the nearest floor below.
Once the cabin has settled at a floor level, the external landing door can be opened using the manual release mechanism. This allows the rescuer to assist the passenger in exiting the elevator.
Airo provides clear instructions for this procedure during the handover process, and our installation team ensures that at least two members of the household are trained in its execution.
Key Point: Even with no electrical power and no action possible from inside the cabin, a person outside can safely bring the cabin to a floor and release the passenger.
Layer 5: Door Lock Malfunction
Scenario: The cabin door lock mechanism malfunctions and the door cannot be opened through normal means.
How Airo Handles It:
The Airo vacuum elevator door is equipped with a mechanical override system that bypasses the electromechanical lock in case of a malfunction. This override can be activated both from inside the cabin and from outside at the landing level.
From inside, the passenger can use the manual door release handle, which is independent of the electronic lock system. From outside, the landing door has a key-operated emergency release that trained household members can use.
In all cases, the cabin must be at a floor level before the door can be opened, ensuring that there is no risk of the door opening while the cabin is between floors.
Key Point: A door lock malfunction does not trap the passenger. Mechanical overrides ensure the door can always be opened when the cabin is at a floor level.
Critical Safety Note
All five layers of safety in the Airo vacuum elevator are designed to work independently. This means that even if one system were to be unavailable, the remaining layers provide alternative paths to passenger safety. This redundancy is the hallmark of a well-engineered safety system.
Additionally, Airo Home Lifts provides:
- Comprehensive training for household members during installation and handover
- 24/7 emergency support helpline for any safety-related concerns
- Annual safety inspections as part of our maintenance programme
- Detailed user manual with step-by-step rescue procedures and safety guidelines
At Airo, we believe that a home elevator should provide complete peace of mind. Our five layers of safety ensure that every passenger — whether elderly, young, or differently abled — can use the elevator with full confidence.
Conclusion
Safety is the cornerstone of the Airo vacuum elevator experience. With five independent layers of protection covering every conceivable scenario — from power failures to door malfunctions — Airo ensures that your family is always safe.
When you choose an Airo Home Lift, you are choosing more than an elevator. You are choosing a safety system that has been meticulously designed, rigorously tested, and built to protect the people you care about most.
