The Importance of Air Hoses

A device used to deliver compression or otherwise to a product (such as an air compressor or pneumatic tool) is called an air hose. Manufactured with durability in mind, the proper operation of an air hose depends on its ability to maintain an airtight seal. We see many applications of air hoses in our daily lives, especially air compressors, which in turn are connected to another device through a hose. Owners will use one to inflate their tires and they are often found on gasoline pumps that can be used for free or for a minimum charge.



For their industrial use or application in a garage or workshop, air hoses are often used with a variety of pneumatic tools that require pressurized or compressed air to operate. These pneumatic tools, such as torque wrenches, sprayers, nail guns, air hammers, air drills and screwdrivers, run on air rather than electricity. When operating these pneumatic tools, care needs to be taken with sharp objects or corners that could damage the air hose.



The importance of air hoses

When working with air systems or pneumatic systems, our main focus is on large components such as compressors, gauges, valves, heaters, blowers, etc. However, we often overlook the smaller components necessary for proper operation, such as a system of hoses. Minor leaks or insufficient or excessive pressure may not produce the desired results and damage parts. There are several factors to consider when understanding the characteristics required for hose selection and setup.

Length

The length of the air hose is the primary determinant of air pressure. They are probably one of the biggest contributors to pressure drop in an air system. One way to control things is to make the length of the connecting hose as short as possible. If long runs cannot be avoided, try using rigid ducting with smooth walls to minimize losses.



The right material

The material of an air hose determines its physical properties such as weight, flexibility, durability and strength. Some systems have specific requirements, so the hose material should be selected based on the application. There are a variety of air hose hoses on the market today that are highly flexible, corrosion resistant, high temperature and pressure resistant, and abrasion resistant.



Maintain airflow dynamics

To maintain consistent airflow, make sure there are no twists and sharp bends in the hose, as this can lead to pressure drop and reduced airflow. If dealing with multiple parallel routes, avoid asymmetry, i.e. keep the length and shape of each pipe the same to avoid uneven airflow.



Selection criteria: physical characteristics / structural characteristics

There are many selection criteria that can be used when choosing the ideal duct or hose. This section covers factors related to the structural properties of the hose that provide many different characteristics that may be important for different applications.

Coiling

Hose with regular coils has better flexibility and elasticity and is therefore expandable and relatively easy to store.



Anti-static

To avoid static build-up, the hose is conductive or semi-conductive.



Pressure resistance

The hose is designed to resist collapse and crushing due to external forces. This feature is important for applications where minor kinks and flow interruptions can cause serious system damage.



Fire resistant

The hose is constructed so that it will not cause damage in the event of fire or flame.
