Pneumatic vs. Traditional Elevators: Which is Best for Your Home?
Pneumatic systems cost $47,500 on average to install, similar to traditional home elevators, but are more energy-efficient, eco-friendly, space-saving, and have reduced maintenance costs.
Updated:
At a glance:
- Pneumatic vacuum elevator (PVE) installations cost between $35,000 and $60,000, while traditional home elevators cost $25,000–$85,000+.
- Pneumatic lifts raise the elevator car using a vacuum pump and air pressure system, consuming only 0.5–1.5 kWh/day. Traditional elevators use either a system of pulleys and counterweights or pressurized hydraulic fluid, potentially consuming three times as much electricity.
- PVE systems don’t need an elevator shaft, giving them minimal space requirements compared to their traditional counterparts.
However, PVE systems also have their own unique pros and cons, so understanding the key differences between them and traditional home lifts can help you make an informed decision. Luckily, our team compares each system below.
Types of Home Elevators: What is Considered Traditional?
Traditional home elevators are generally shafted models, meaning that they require a dedicated elevator shaft to function. Many also need a separate machine room, though some modern models offer machine-room-less (MRL) designs. With that in mind, space efficiency is often a major concern for senior homeowners looking to install one of these home elevators.
The two most common types of traditional elevators are traction and hydraulic systems. They have different lifting mechanisms: the former was invented in the early 1900s, and the latter as early as the 1820s. Here are the key features of both options:
- Hydraulic elevators: Use pressurized hydraulic fluid (usually oil) to lift and lower the elevator cab. An electric motor powers a hydraulic pump, forcing fluid into a cylinder, where the pressure drives a piston upward to raise the cab. To descend, the fluid is released back to where it’s stored within the machine room. These elevators are known for their smooth ride and powerful lift, which can hoist heavy loads up to 60 feet.
- Traction elevators: These elevators work using a system of pulleys, counterweights, and steel cables to achieve lift. The electric motor drives the pulley to lift the cab along guide rails inside the shaft, while the counterweight reduces the energy consumption needed for the lift. Their construction allows them to reach 100 feet or more, and they’re also more energy-efficient and eco-friendly than most hydraulic systems.
How Does a Pneumatic Elevator (PVE) Work?
Invented in the early 2000s, Pneumatic vacuum elevators (PVE) are a more modern design for senior homeowners with limited available space. Instead of needing fluid or hoist cables, they use air pressure to move between floors. They also don’t need an elevator shaft or machine room; only a small cutout in the floor is required for proper installation.
In more detail, PVE systems rely on a vacuum pump to achieve movement, as it controls air pressure above and below the airtight cab. To travel to upper floors, air is pulled from above the cab to create pressure. To go down, that pressure is removed, allowing gravity to facilitate a smooth descent.
This overall design makes PVE more energy-efficient, space-saving, and less upkeep-intensive than traditional options.
Traditional vs. Pneumatic Elevators: Pros and Cons
Comparing different options to find the best residential elevator installation for your home? Below, we’ve compared the pros and cons of traditional and pneumatic elevators based on several key factors:
Space Requirements
- Pneumatic: Easy to retrofit into two to five-story homes, as their compact design doesn’t require an elevator pit, shaft, or separate machine room. Instead, simple holes are cut into the floor to make room for the hoistway cylinder.
- Traditional: Most designs require an elevator pit, shaft, and machine room, making them a less viable option for homes with limited space or delicate structures.
Installation
- Pneumatic: Offers significantly faster installation, with most professional technicians completing the task in less than a week. Installation may or may not be cheaper depending on the company and model.
- Traditional: Some traditional lifts have lower upfront installation costs but can take several weeks to months to properly install.
Energy Efficiency
- Pneumatic: Advanced air pressure and vacuum technology allow these systems to consume less energy on average (only 0.5–1.5 kWh/day).
- Traditional: Traction elevators are slightly more efficient than hydraulic systems, but both have the potential to consume as much as three times the electricity as PVE (1.0–5.0 kWh/day).
Regular Maintenance
- Pneumatic: The lack of a shaft and fewer complex parts generally means that PVE systems require less maintenance, as they eliminate risks associated with oil leaks, fluid replacement, cable adjustments, motor servicing, and counterweight repairs. Most only need servicing every five years.
- Traditional: The shaft, machine room, cab, and lifting mechanisms need to be checked every six months to a year, increasing overall maintenance costs.
Weight Capacity
- Pneumatic: While some models are wheelchair accessible, they have less heavy-duty durability. Overall weight capacity is almost always lower than that of traditional systems.
- Traditional: These systems, and especially hydraulic elevators, provide a powerful lift that can handle wheelchairs, several passengers, and other heavy loads.
Travel Distance
- Pneumatic: Highly reliable for travel between two floors, but most models can’t rise above 50 feet.
- Traditional: Hydraulic lifts are capable of reaching 60 feet, and many traction models can rise over 100 feet. This makes these systems more functional in high-rise buildings.
Environmental Impact
- Pneumatic: Don’t require excavation and have no risk of leaking hydraulic oil, making them a cleaner option with fewer environmental concerns over the course of their operation.
- Traditional: Shaft construction and issues like oil leaks can all have a detrimental impact on the environment, resulting in costly cleanup or reduced property values.
Tips For Choosing The Best Elevator Type
Choosing between a traditional or pneumatic elevator isn’t always easy, especially when you’re trying to find the best solution for your home layout, mobility needs, and budget. Below, we’ve gathered a few essential considerations to help you make the right investment:
- Evaluate available space. Shafted lifts require 5×5 feet (25 sq ft) for the shaft, 8–12 inches for the pit, and between 7–10 feet of overhead clearance, space that not every home has. If you’re worried about being able to fit an elevator installation, a compact PVE may be the perfect solution.
- Meet your mobility needs. Pneumatic lifts aren’t always the best option when you need to carry multiple passengers (a caregiver or family member) or move heavy medical equipment. If you need a high weight capacity, traditional systems are usually more durable in the long term.
- Consider travel height. Pneumatic elevators are ideal for two-story homes, while traditional systems are more practical for high-rises over 50 feet tall.
- Compare long-term costs. While the upfront cost of both models can be similar, pneumatic systems have fewer maintenance requirements and consume less energy over time, helping you save money on long-term costs.
- Factor in home disruptions. PVEs are typically installed faster and with minimal construction, whereas traditional elevators often require weeks of structural modification.
- Consult a professional. Reach out to trusted, local elevator companies to professionally assess your home, explain code requirements, and recommend the best elevator for your situation.
The Bottom Line: Pneumatic Elevators Offer a Space-Saving Aging-in-Place Solution
While there are many residential elevator types to choose from, seniors with limited space who still want to age in place should consider pneumatic lifts. As long as you don’t live in a high-rise or need to carry heavy loads, these systems offer energy and space-saving performance. Unlike traditional systems, PVE doesn’t require construction of an elevator shaft or machine room, saving time, money, and long-term maintenance costs.
However, the best choice ultimately depends on your unique situation, so we always recommend reaching out to a professional elevator company to discuss your needs.
Frequently Asked Questions (FAQs) About Pneumatic vs. Traditional Elevators
Not necessarily. Pneumatic lifts generally have a higher starting price ($35,000) than traditional lifts ($25,000). However, more realistically, many traditional lifts can cost well over $85,000, whereas PVE options rarely cost more than $60,000.
Neither PVE nor traditional systems are covered by Original Medicare, but Medicaid, Medicare Advantage, and local non-profits may offer programs that cover them as medically-necessary home modifications. Programs vary by region, so be sure to visit your state’s website for accurate information.
Complex pits, shafts, and other mechanisms generally give traditional elevators higher maintenance costs, though traction systems may last longer than PVE systems.
Pneumatic elevators consume far less electricity than their traditional counterparts, especially hydraulic systems. In fact, hydraulic systems may consume more than three times the energy, increasing your monthly utility bills.
Most in-home pneumatic elevator installations are for travel between two floors, but they have the potential to reach 50 feet (4-6 floors). Traditional elevators are capable of traveling higher, but require structural changes.
