Moving Sensitive Equipment with Air Skates | IES

Whether you’re transporting high-value equipment within a cleanroom environment, positioning delicate scientific instruments, or aligning heavy tools, traditional moving skates often lack the level of precision, accuracy and care that you need.


Air skates (also known as air casters) are redefining how engineers handle complex equipment moves. By lifting heavy loads on a controlled cushion of air, they provide a friction-free, highly accurate way to manoeuvre delicate tools safely.

In this guide, we break down how air skates work, their key advantages, the common challenges, and why they’re becoming a vital technology for high-precision equipment relocations.

Why traditional moving skates fall short

Conventional moving skates are designed to carry heavy loads. But they’re not the best choice for moving more sensitive, high-technology, precision equipment (for example, scanning electron microscopes).

Their limitations include:

1. Friction, vibration and impact

Wheeled skates create unavoidable friction and vibration. For delicate tools, even minor shock loads or floor imperfections can compromise alignment or functionality.

2. One-directional movement

Traditional skates are often one-directional and require steering mechanisms and repositioning efforts just to help them change direction, slwong down your move.

3. Restricted paths

Because removal routes are often indirect, that means you’ll likely have to remove or shut down any pieces of equipment that are in the way, causing cascading delays for production and significantly impacting your bottom line.

For controlled, low-impact movement, you need a more advanced solution.

Introducing Air Skates: A New Standard for Precision Moves

Air skates create a thin cushion of air between the load and the ground.

This acts as a lubricating layer, reducing friction and allowing the load to “float” slightly above the ground (similarly to how a puck floats on an air hockey table, but in a much more engineered and industrial form).

Here’s how it works:

  • Multiple air pads/air bearings sit beneath the load
  • A compressor and hose system feeds air into the pads
  • The pads inflate, creating a thin air cushion between the load and the floor
  • This eliminates most friction, enabling smooth, multidirectional movement

The result is a level of precision and control that traditional systems simply cannot achieve.

The Benefits of Using Air Skates for Equipment Moves

1. Ultra-Precise Multidirectional Movement

Air skates allow equipment to move effortlessly in any direction (forward, backward, sideways or diagonally) without needing to reposition the system. And with exceptional control.

Operators can control movement by adjusting air pressure, making alignment tasks simpler and far more accurate.

This also allows teams to navigate around obstacles rather than removing other tools, saving time and preventing disruption.

2. Minimal Friction and Vibration

Because equipment floats on a cushion of air, it avoids the harsh mechanical contact associated with wheels or rollers.

This greatly reduces the risk of:

  • Vibration damage
  • Misalignment
  • Floor marking
  • Micro-shocks that can affect sensitive tools

For environments where precision is essential, this is a major advantage.

3. Even Weight Distribution

Traditional skates concentrate weight on a handful of rollers. Air skates distribute the load evenly across all air pads, reducing:

  • Floor stress
  • Equipment strain
  • Risk of cracking, indentation or damage

This makes them ideal for delicate floors, cleanroom environments and heavy-duty equipment moves.

4. Improved Safety for Engineers

Air skates reduce manual pushing force dramatically. For example, just 5 kg of force can move a 1-tonne load.

This minimises risk of strains, slips or injuries, reduces reliance on large lifting equipment, and makes manoeuvring much safer in confined spaces or cleanrooms.

Challenges to Consider When Using Air Skates

Even with their huge benefits, air skates must be used correctly and under the right conditions. Here are the main factors to assess.

1. Angles and Inclines

Air skates perform best on flat surfaces. Even small inclines can cause loads to drift or roll, creating safety hazards.

Best practice:

  • Survey the entire move path for slopes
  • Manage inclines using additional equipment (ramps, wedges, tow lines)
  • Plan carefully to avoid uncontrolled movement

2. Floor Gaps, Voids and Joints

While air skates can traverse small cracks or expansion joints, larger voids may cause the air skates to drop and stick.

Best practice:

  • Identify and measure any voids
  • Use bridging plates or ramps where required
  • Ensure transition plates can support the full load

3. Diaphragm Damage

The air cushions rely on a reinforced diaphragm. Sharp debris, loose screws or surface hazards can puncture or rupture the bladder, causing loss of lift, sudden tool drops and unforeseen safety risks.

Best practice:

  • Inspect move paths thoroughly
  • Remove debris and obstacles
  • Use protective plates on imperfect flooring
