Energy Savings give a one year ROI  
 

A large Household cleaning product bottler recently contacted Paxton about replacing their compressed air nozzles with a Paxton blower and air delivery system.  They provided the following information:
 

• Three compressed air fan nozzles
• Operating at 75 cfm and 80 psi
• Energy usage per year was $9,893, assuming an energy cost of 7 cents per kW hour 
   

Paxton engineers designed a drying system for them that included a 3 hp centrifugal blower and 10 nozzles for air delivery.  This system provided 300 cfm at 1 psi, guaranteed by Paxton to dry as well as -- or better than -- the existing compressed air system.  Energy usage for the Paxton system is only $1063 per year and resulting in energy savings of $8830 per year and a less than one year return on investment on the cost of the blower system.   

We also recently designed a system for an automobile manufacturer for wheel and tire blow off.  In this case, cost to operate the compressed air system was $4.40 per hour, and the cost to operate the Paxton system was only $0.74 per hour.   The return on investment for this system was less than 1.2 years.  Learn more.

Why are blowers more efficient?

According to a U.S. Department of Energy study, 10% - 30%  of an industrial facility's electricity costs are the result of generating compressed air.The efficiency of a compressed air system may be as low as 10-15%, meaning compressed air is one of the most expensive sources of energy in your facility. For example, it typically takes 7-8hp of electrical power to run an air compressor to operate a 1hp air motor (at 100psi).  Too much energy is used in compressing and transporting the compressed air, leaving less energy to do the drying and blow off work.  

Paxton blowers, on the other hand, are at least 60% efficient, as compared to regen blowers that are only 30 - 40% efficient.  This means that the majority of the energy used is being put to work drying and blowing.  Typically, Paxton blowers will use only 20% of the energy that is used by a compressed air drying system.    
 

One of the most common issues that I see is that the the direction of rotation is not correct during the initial startup and the blower ends up running in reverse. A blower that runs backwards is not obvious -- it will still produce pressure and flow but at a much lower rate. Some of the tell-tale signs are: belt chirping or squealing at startup, excessive belt dust near the pulleys and belt guard, belts lasting less than a few weeks, poor performance, and excessively low current draws. This is remedied by simply swapping any 2 leads of the 3 phase connection to the motor (L1, L2, or L3).  Call or e-mail if you need assistance with this.
