Energy Saving and Efficiency with Pressure-Reducing Blow Guns

Energy saving in the use of compressed air are a key focus for many companies seeking to improve the efficiency of their production processes. A crucial aspect of these savings is reducing the pressure of compressed air, which has a direct impact on energy consumption. For example, a reduction of 1 bar in pressure results in an approximate 8% reduction in electricity consumption (see study by the Federal Environment Agency, pp. 64-65, in German). This translates into significant economic and environmental benefits, especially when a systematic approach is adopted to optimize the use of compressed air.

Eliminating Improper Uses of Compressed Air

One of the first steps toward energy efficiency is eliminating improper uses of compressed air, meaning tasks that can be performed more effectively or efficiently with alternative tools. Using compressed air unnecessarily wastes valuable resources, both in terms of energy and operational costs.

Using a Blow Gun with a Pressure Regulator

A practical example of optimization is the use of a blow gun with a pressure regulator. Reducing the pressure from 6 bar to 3.5 bar can lead to substantial savings.

Lowering the pressure not only reduces energy consumption but also maintains the effectiveness of the blowing process, as the air is still used efficiently. With a reduction of 2.5 bar, energy savings can reach approximately 20%, significantly lowering the costs associated with producing compressed air. Note that this applies only to the consumption of the blow gun. To achieve savings across all pressure equipment, the entire system pressure would need to be reduced to 3.5 bar.

Optimized Air Control

A blow gun without pressure control at 6 bar can consume over 300 liters of air per minute. However, using a pressure regulator reduces consumption to less than 150 liters per minute. This halving of air consumption decreases the number of compressor starts and stops, extending its lifespan and reducing maintenance costs.

Consider a company that uses an average of 10 blow guns in its department: the impact on the compressor would be significantly reduced with a pressure reduction system, leading to collective savings.

Noise Reduction and Increased Safety

In addition to energy savings, another important advantage is noise reduction. Blow guns operating at 6 bar generate high noise levels, often exceeding the 85 dBA limit set by European regulations. Installing blow guns with a pressure regulator drastically reduces noise levels to 75 dBA. This not only creates a safer working environment but also enhances operator comfort.

SUVA Pro

Finally, the use of blow guns with pressure regulators, such as those certified SUVA Pro, contributes to improved safety and efficiency, making them a beneficial choice for energy savings and worker protection.

The certification consists of tests to ensure the product is safe and reliable. The two most important tests are:

1. Noise test (Leq < 85 dBA)
2. Burst test (72 bar for 30 seconds)

This is a type examination, meaning the product is declared compliant with safety and health protection requirements by an independent Swiss organization: SUVA.
