This is a conservative figure, as most compressors will produce 5 or 6 SCFM. For example, a 25 HP compressor will produce at least 100 SCFM of air as shown in the far left column on the same line as 25 HP. On steady pumping, a compressor will produce a minimum of 4 SCFM air flow for each 1 HP of capacity. To make a realistic estimate of air flow volume, the far right column of the chart showing compressor HP may be used. Other applications, usually on small systems, may have to carry a high surge of air if several machines happen to be operated at the same time, then there may be a period with almost no flow. On some applications, like in a large plant with many legs in the distribution system serving dozens of air-operated machines, the air usage may be at a fairly steady rate. It is difficult to estimate the air flow volume to be carried in each leg of the distribution system. The left column of the chart shows the volume of air to be carried. If carrying 80 PSI pressure these pipes will carry slightly less air at 1 PSI pressure loss than shown in the chart. If carrying 120 PSI pressure these sizes will carry slightly more air than shown, or pressure loss will be slightly less than 1 PSI. To hold the distribution loss to 1 PSI, pipes of larger diameter must be used on longer runs to carry the same flow that can be handled by smaller pipes on shorter runs.įigures in the body of the chart above are pipe sizes recommended on a 100 PSI system to carry air with less than 1 PSI loss. When measuring lengths of runs, add 5' of length for each pipe fitting. The pipe size depends not only on the volume of air flow but how far it must be carried. Contact us for more information and pricing.On a compressed air distribution system, pressure losses greater than 3% are considered excessive, and a well-designed system having a steady rate of air flow is usually designed for not more than a 1% loss or 1 PSI for a 100 PSI system.Speak to our sales team for advice on how such a system can be integrated into your operations.

The key is then used to release the air hose lock from the trailer and allow the vehicle to drive away.Once (un)loading is completed, the chain is re-inserted into the lock and the key can then be removed.This then allows access to the ramp and (un)loading operations can commence.This coded key is then inserted into the chain lock on the ramp to release the chain.Then, and only then, is the key released from the air hose lock. The air hose lock is connected to the red ‘suzie’ air hose connector. CABLE PROTECTORS CABLE/HOSE PROTECTION SYSTEMS featuring the worlds most trusted brands Our cable protectors feature a patented modular, interlocking design.Access to the ramp is prevented with locked chain.
