Pneumatic jackhammers are powered by compressed air, making them ideal for environments where electricity or fuel is not readily available. They are typically lighter than electric or hydraulic models, which can reduce operator fatigue during extended use. However, they require a reliable source of compressed air, which may necessitate the use of air compressors on-site. Pneumatic jackhammers are often used in underground construction sites due to the absence of electricity.
