• • • • • • • SIZE • • • • • • • The larger the inside diameter of the hose, the greater the airflow. This of course comes at the expense of flexibility, ma neuverability, and overall weight. To help determine the right size of hose to use, it is important to know how much air is required to power your pneumatic tool or equipment in Standard Cubic Feet per Minute (SCFM). Generally, nailguns or staplers require 1-3 SCFM to operate properly, so a 1 ⁄ 4 " I.D. air hose will work regardless of hose length. An impact gun on the other hand, may require up to 90 SCFM and therefore a 3 ⁄ 4 " or 1” I.D. hose would be necessary depending on the hose length. Often times, the air tool manufacturer will list the minimum hose size required under the tool specifications. Remember, hose size is ordered by inside diameter (I.D.), while unreinforced tubing is often ordered by outside diameter (O.D.). • • • • • • LENGTH • • • • • • Longer is not always better. It is important to choose the length of hose based on your needs. This will allow for maximum ma noeuvrability for your pneumatic tool while limiting pressure loss. To do this, measure the distance from the hose connec tion to the furthest point of use. Choose a length that will be long enough to reach all required workspaces without being stretched. Be sure to factor in an extra few feet of clearance for unexpected situations. Remember, the longer the hose, the greater the pressure drop. • • • • • • PRESSURE • • • • • • When considering pressure, it is important to factor in the maxi mum working pressure of your compressed air system as well as the required working pressure of your tool or equipment. Not all air hoses have the same working pressure. By choosing an air hose with a working pressure that exceeds both your air system and your tool, you can ensure optimal performance of your air tool while avoiding the risk of hose failure. For added safety, we strongly recommend the use of safety couplings and regulators to help control the pressure of your air system while also main taining the ability to vent downstream pressure and eliminate accidental disconnection. • • • • • • MATERIAL • • • • • • With so many different options on the market today, choosing an air hose can be a bit daunting. At Green Line, we take a lot of the guesswork out by only offering premium, industrial grade products, so your air hose can withstand the tough rigours of everyday use. Green Line carries hybrid polymer, rubber, and polyurethane air hoses as well as unreinforced tubing made from a wide range of materials. Each material offers its own unique advantages so before choosing your air hose, it is important to know the work environment where the hose will be used. Some examples of questions you may want to ask… ■ ■ Will the hose be exposed to sub-zero temperatures? Premium Air & North Wind are both rated to -54°C. ■ ■ Will there be sparks near the hose, such as in a welding shop? Multi-Purpose Rubber will stand up to the heat. ■ ■ Will the hose be used in an oily environment? Push-On hose is oil-resistant and easy to assemble. ■ ■ Will the hose be used outdoors for framing or roofing? Polyurethane Air is lightweight yet puncture resistant. ■ ■ Does assembly need to be quick and easy? Unreinforced tubing is designed to work with push-to-con nect fittings. Ultimately, choosing an air hose comes down to performance and material compatibility.
