The global market for pneumatic tools is projected to steadily grow as the demand for these tools increases in a number of manufacturing sectors, including the construction and automobile industries. Pneumatic tools, also known as air tools, are powered using compressed air which is supplied through an air compressor rather than via electricity or a battery supply. Examples of commonly used air tools include pneumatic grinders, drills, sanders, wrenches and grease guns.Some of the benefits of choosing air tools over electric ones include the fact that they are lighter, less expensive, easier to handle and offer a solution in remote locations where a ready power supply may be lacking. Pneumatic tools also contain fewer moving parts, which makes them easier to maintain and, due to their greater power-to-weight ratio, are able to produce more horsepower which can be adjusted according to need.In this article, we will focus specifically on pneumatic screwdrivers and their applications.

What Are Pneumatic Screwdrivers?

Screwdrivers are one of the most common tools used within the manufacturing industry to secure parts together. A pneumatic screwdriver is a popular air tool for tightening that operates using compressed air in order to tighten and loosen screws.In addition to its torque range and screw capacity, when selecting a pneumatic screwdriver, other performance values to consider include its energy consumption, speed, power, vibration emissions and noise levels.From a durability perspective, it is advisable to select a screwdriver that has a larger motor size and a capacity in excess of the target torque instead of a smaller motor at its capacity limit, which can result in clutch failure. 

Screwdriver Shape

Screwdrivers come in a variety of different shapes and the following tips can help in making the correct selection choice:
  • Pistol Grip Screwdrivers: This shape of screwdrivers allows for a firm grip and good support in terms of wrist load when operating. It is recommended for larger screws, especially self-driving screws, as well as wood and sheet metal screws.
  • Straight Screwdrivers: These tools are ideal for fixed workstations and vertical use. With either lever, push or combined lever and push start, there are multiple options to choose from.
  • Angle Head Screwdrivers: Mainly used for accessibility purposes, these screwdrivers have an angle head attachment designed for use in tight spaces. They are suitable for the higher torque range due to their effectiveness in counteracting reaction forces.

Air Motor

Air motors offer the greatest power and portability in relation to weight and dimensions ratio for power tools. They are wear resistant, robust and can withstand overload making them ideal power units in portable screwdrivers. Air motors enable pneumatic screwdrivers to be smaller and easier to handle and can be used without any risk of short-circuiting or electric shock. 

Installation of Pneumatic Screwdrivers

A pneumatic screwdriver uses approximately 3 and 15 litres of compressed air per second. Correct airline installation involves the necessary compressed air accessories and tools to ensure a sufficient air supply to the motor.Did you know that we have our own product range of air tools, in addition to air compressors and other compressed air services?
