Apneumatic is a term used for describing something that lacks the presence of air or gas. The spelling of apneumatic can be broken down into three parts: "a-p-n" represents the prefix "a-" meaning "not," "pneu-" is derived from the Greek word "pneuma" meaning "air or gas," and "-matic" which means "related to or characterized by." In IPA phonetic transcription, it is pronounced as /æpˈnjuːmætɪk/. This term can be used in various fields including engineering, biology, and medicine.
Apneumatic is an adjective used to describe objects, systems, or mechanisms that do not rely on or operate with air or pneumatic pressure. The term can be broken down into its two components; "a" meaning without or not, and "pneumatic" referring to air or gas pressure.
Apneumatic devices are distinguished by their ability to function without the use of compressed air or other gaseous substances. Instead, they often utilize other sources of energy, such as electricity, hydraulics, or mechanical force. Examples of apneumatic technologies include electric motors, hydraulic systems, and mechanical levers.
In the context of engineering, the apneumatic concept is often applied to describe the design and operation of tools, machines, or systems that offer advantages over pneumatic alternatives. These advantages may include enhanced precision, reduced noise levels, increased durability, or improved efficiency. Apneumatic solutions can be found across diverse fields, ranging from automotive manufacturing to medical equipment.
The term apneumatic can also be extended to describe objects or systems that lack the capability to contain or store compressed air or gas. For instance, a container or vessel with no pneumatic properties can be labeled as apneumatic.
In summary, apneumatic refers to objects or systems that function independently of air or gas pressure, either by using alternative energy sources or by lacking the capability to contain compressed air.

The word apneumatic is derived from the combination of two Greek roots: a- meaning without or not, and pneuma meaning breath or spirit. Hence, apneumatic literally means without breath or without spirit.
