I have an application that requires 1000 SCFH at 20 psi. Can anyone help me size an air receiver that would handle an event that would last 45 min. The tank can only be charged to 100 psi. Does anyone know of a software progragm that could calculate this using other values. Thanks in advance.

Don Always loved that Aussie humor! Good Luck, if I can help you in any way, let me know. And a Happy New Year to you as well. Dilligaf

don1 Funny you should ask? Atlas makes the first true vsd compressor, designed from the ground up. The savings are there. First off, you need to determine what it is costing you to operate your current machine. There is is a standard formula for calculating that. Next, you need to develop a...

Jbartos Thank you so much for your help on this matter. I have been researching this for one of my customer. After your help and the research you have provided, I am convinced that a standard duty simply won't work and would not be cost effective. Thanks Dilligaf

Lord Calvin The advantage to using robots is to increase productivity and decrease waste. Robots have a extremely high rate of repeatability. They don't have the individual characteristics of a human operator. Robotics takes human error out of the equation, not to mention that they never call...

jbartos On the surface, that would seem like the logical thing to do. The problem is that I-R uses a special extended shaft motor upon which the main drive gear is mounted on the end. I have search many motor catalogs for an inverter duty motor of this type with no sucess. Next question is...

Don Thanks for your input. The purpose of using a VFD on a rotary screw is to match KW consumption to actual air usage. There are a couple of manufacturers who already make VFD designed units. Typical energy savings is in the 30% range. The problem is they use an inverter duty motor. My...

This has been very helpful, but with increased cooling for the motor can the speed be lowered below 50% of nameplate speed. Also would I be better off using an Inverter Duty motor. Also, nothing was mentioned about de-rating the standard motor service factor? Thank you again, as I said your...

What are the draw-backs of using a standard duty motor with a Variable Frequency Drive as opposed to installing an Inverter Duty Motor? Does the motor service factor get de-rated under this service. The application is a 200HP I-R Rotary Screw Air Compressor.
