The rotary screw machine is best suited for high cfm loads or continuous high air demands, that is really where the 100% duty cycle shines, meaning it will run the entire work day. If you are expecting a machine to start and stop throughout the day, to supply air intermittently, then it would be more appropriate to run a reciprocating compressor. As for the boiler room placement, as long as the air is clean and dry and there is space to install and perform maintenance you should be okay. In regards to the temperature in your boiler room however, if the ambient air is too hot, that will lead to higher temperatures inside meaning more friction and could lead to issues or damage. An aftercooler would help however that only removes heat after the compression cycle.

Install the dryer where it is most convenient in your system, as the distance does not matter much if at all in your application

Reciprocating compressors have their place, they meet a different requirement and are also more economical. They are ideal for applications that require intermittent use of air, rather than a constant demand. An example of the difference would be using pneumatic tools versus paint spraying.

I'm sorry, did you watch the video or read the description? Our video may not have all the info, and we can always improve, but "absolutely no info" is not what others got out of this video. What do you need help with? We would be more than happy to help.

Thanks for the great question. For your applications of powder coating, painting, and sand blasting - those processes have a large air demand. Running a sprayer or blaster off of a piston compressor comes with disadvantages. The duty cycle of the piston compressor is 50%, meaning it needs half the run time to be idle and cooling, so you are limited to what is charged in the receiver while it is off. The rotary screw is designed with 100% duty cycle, meaning it will run the entire time and put out much more air. The rotary screw is also quieter, if you work in the vicinity of the compressor that is an enjoyable benefit. As for which produces cleaner air - the rotary screws are oil soaked and there is typically more oil carryover in comparison to a piston compressor, however there is an air/oil separator that helps capture that. You will notice as you checkout our online store that the Reciprocating piston compressors are typically more affordable, while the Rotary Screws have a higher price tag. Another option similar to a rotary screw is a rotary vane compressor, we offer some and are very popular so check them out! For the applications you mentioned, especially when it comes to paint, we definitely recommend having a compressed air dryer along with general purpose and high efficiency filters, and a water separator/water trap as well. What this will offer your system is extremely clean and dry air - it removes all condensation/moisture/bulk liquid/particulate/oil/dirt and debris. Let us know if you have any other questions, feel free to email or call! Check out our CFM calculator if you need help estimating your air demand in CFM, and we would recommend a rotary screw for you.

You’re welcome in advance

Thanks for the question, for your application being mobile we would recommend a free-standing pneumatic controlled tower style air dryer that utilizes desiccant rather than a refrigeration cycle.

Thanks for your question, for getting air out of your air lines you would need to pull a vacuum on the distribution system, although I don't think that is what you mean. If there are air bubbles entrained in your gel coat, it could be due to incorrect pressure, unless the bubbles are from moisture in which you would need better air treatment.

No I was just making a statement. I use my air dryer to get the moisture out so I can spray gelcoat. I'm not sure if it's working though because there is never water in the bottom in the pan but that may be due to it being colder outside lately here in north Florida. I bought a used one its an arrow brand one with only 1 gauge that says refrigerant vacuum (I think that's what it says but I'm not at the shop) and it goes to 30 when I turn on the unit and the unit all turns on, I'm just not sure of it's cooling. I need to wait for a hotter day. I have it going from my gas compressor outside, running in a 1/2"od line to my auxiliary tank inside then from auxiliary tank through filter then through refridgerated air dryer then into desiccant dryer to line for spray gun. Any tips on determining if air dryer is not working? I bought it used so I'm not sure how to tell. Have not had to paint with it since buying it.

Thanks for a great question! For tire shops we would recommend a reciprocating air compressor. The demand for air in this type of application is intermittent, so the compressor can cycle on and off as needed. It is also a more affordable option. Contact us by email or phone with any other questions!

Thanks for your comment, the noise difference between the two machines is significant. The reciprocating pistons banging away all day is much louder than the quiet purr of the rotary screws. If you have employees that work in the vicinity of the air compressor, this can be an important quality of life issue, or atleast one needing ear plugs.

Great question. The beauty of a rotary screw is that it is designed for a 100% duty cycle, meaning it will run all day to keep up with your continuous use of air. Painting, grinding, and sanding are large air loads, and with 3-4 people working at the same time, that is a big demand. We would recommend something that can handle around 30 CFM for those tasks so you would be looking at a 10 HP rotary screw. Check out our CFM calculator, punch in the tools or number of techs you have, and it will show your air demand compressedairusa.com/cfm-calculator/

Respectfully, we would disagree. For a compressor that can handle a 100% duty cycle, with storage receiver and built in air treatment this machine does have a small foot print. For reciprocating air compressors to handle the same load you would need a larger machine, in addition you would also have to separately pipe in a larger receiver, air dryer, and filters.

Christopher thanks for asking... you are correct .4m^3/min is roughy 14-15cfm. For this air demand we would recommend a 5HP rotary screw. We carry these machines in a tank mounted configuration, with or without a built in air treatment system.
