• Description : Length The Pu Air Hose is commonly supplied in a choice of lengths, and it's possible to get many different lengths of hose for various types of application. The length you choose is dependent on the distance you need to cover between the compressor and the workspace of the pneumatic tool. A long hose will allow a greater separation between the workspace and the compressor, but some of the air pressure will be lost in transmission. A shorter hose is more manoeuvrable in tight spaces, maintains pressure better, and works well with a portable compressor.

Overview

• Length
  The Pu Air Hose is commonly supplied in a choice of lengths, and it's possible to get many different lengths of hose for various types of application. The length you choose is dependent on the distance you need to cover between the compressor and the workspace of the pneumatic tool. A long hose will allow a greater separation between the workspace and the compressor, but some of the air pressure will be lost in transmission. A shorter hose is more manoeuvrable in tight spaces, maintains pressure better, and works well with a portable compressor.

  When deciding how to choose the right air hose, a lot depends on the manoeuvrability of the pneumatic tool and the size of your workspace. Shifting the compressor may be simpler than trailing a long length of hose. However, if your application requires you to move around a lot, such as using a spray gun in a body shop, then a longer hose will be needed. A shorter hose can always be extended by supplementary hoses and couplers, although you should expect to experience small pressure drops where couplers are used.

  Internal Diameter
  The ID of the hose is important in determining the rate at which the compressed air can be supplied, with the most common IDs being 6mm, 8mm and 10mm. The greater the diameter, the more litres per minute (l/min) of air can be supplied to the pneumatic tool. On the other hand, a larger bore will also add significantly to the weight of the hose, and make it less manoeuvrable.

  You should calculate how many l/min of air your application will require. Then choose the corresponding ID necessary to supply that air, and maintain its pressure over the distance travelled. The higher the l/min, the bigger the ID that you'll need, with most hand-held tools using a 6mm hose, and more heavy-duty applications needing an 8mm or 10mm. If your pneumatic tool has the same l/min requirement as the output of your compressor, you should use a shorter, wider hose to minimise loss of air pressure through friction.

  Straight or Curly?
  Choosing the right air hose also involves the choice of a standard, straight hose or a curly, recoil one. Standard hoses lie flat, without coils or bends, but they can get kinks in them which reduce or cut off the air supply. On the other hand, they're easy to handle, offer no resistance and can be gathered up into loops for storage or mounted on a hose reel. Curly or recoil hoses are like old-fashioned telephone cables, with a lot of small, regular coils making them seem much shorter than they actually are. These coils are highly tensile, and spring back in place after use, as they are designed with a memory. They are easy to store and to keep out of the way when not in use, but they offer resistance and require some strength to stretch them out, particularly if they're long or have a large l/min.
