What Positive Displacement Blower is Right for Your Needs?


Find Out For Yourself With Our FREE Pneumatic Blower Sizing Calculator!

Pneumatic conveying is an economical and practical option for transporting bulk material through your plant.  When designing a pneumatic conveying system, selecting the correct blower is absolutely critical. P.D. blowers are rated according to required pressure and volumetric flow.  Any miscalculation in these factors will result in a conveying system that is oversized, prone to pipeline blockage, or incapable of achieving the material flow rate required.

Lubbock Electric Co. has decades of experience in calculating blower rating requirements for agricultural and industrial applications.  What we used to calculate by hand can now be achieved with programmed spreadsheets.  We want to share this capability with you. This free download is our exclusive P.D. Blower Sizing Calculator.  It is a ready-made Microsoft Excel spreadsheet with the required calculations.  On the spreadsheet, you simply select your pipe diameter, conveying distance, system elbows, and volume output.  The volumetric flow (CFM) and pressure (PSI) required will be calculated, and a Roots brand P.D. blower will be recommended to you on the "Print Sheet."  If your needs are outside of the scope of the calculator, you can consult Lubbock Electric for a custom solution.

Of course, this calculator cannot completely replace a consultation with our pneumatic specialists.  When you're ready to order, print out your calculator results page and contact a Lubbock Electric salesperson to order your equipment.
