Introduction
An air ratchet (also known as a pneumatic ratchet wrench) is a professional workshop tool powered by compressed air that makes fast tightening and loosening of bolts and nuts much quicker and easier than manual ratchets. These tools deliver reliable torque with smooth control — ideal for automotive, mechanical and industrial applications.
Air ratchets offer key benefits for NZ trades and mechanics:
Fast operation: Rapid reciprocating action speeds up loosening/tightening tasks.
Torque in a compact size: Great for working in tight spaces under bonnets or machinery.
Precise control: Adjustable throttle lets you manage torque and avoid damage.
Durable for workshops: Metal gear trains resist dust and moisture common in harsh environments.
1/4″ Air Ratchet: Best for light work and small bolts — ideal for panel work and mechanics in compact spaces.
3/8″ Air Ratchet: Most popular size — versatile for general automotive and maintenance tasks.
1/2″ Air Ratchet: Heavy‑duty option for larger fasteners and intensive workshop use.
When selecting an air ratchet:
Torque output: Higher torque for tougher fasteners. Check specs on each model.
Air consumption: Ensure your compressor can deliver adequate airflow (CFM).
Free speed (RPM): Faster tools save time on repetitive tasks.
Ergonomics: Comfortable grip and lightweight design improve handling.

Q: What’s the difference between 1/4″, 3/8″ and 1/2″ air ratchets?
A: Drive size refers to the socket connection and typical torque range — 1/4″ for light jobs, 3/8″ for general use, and 1/2″ for heavier bolts.
Q: Do I need a special compressor for an air ratchet?
A: Ensure your compressor can supply sufficient CFM at around 90 PSI to power the ratchet continuously.
