Compressor Questions
Thanks for the warm welcome! I'm excited to be able to be here and support you! I do travel a lot, so I will respond to questions, but it may be well into the evening (like now) before I'm able to get back to you.
I see lots of questions about compressors. The EXT420 doesn't care what kind of compressor it is connected to, the only thing it cares about is how much air (in CFM) and the pressure. As I mentioned previously, to run the pump at the maximum stoke rate (about 60 cycles per minute), the pump will consume about 25 CFM at 90 - 100 psig. Our air quality recommendation is a 40 micron filter (or better) to stop particulates, dry to a dew point of 40 deg F (these are not very aggressive requirements).
Regarding the type of compressor, I'm not a compressor guy, I would suggest that you contact a local compressor distributor (I would suggest something better than what you get at Home Depot or Sears). I stopped by a compressor distributor recently and they had both 3 phase screw compressors that would do the job (around $10,000) and they had single phase (220 VAC) piston compressors (7-1/2 HP) that would also do it (about $3,000). In the long run a screw compressor, driven by a 3 phase motor will hold up longer and will be much more energy efficient with less maintenance. If you are planning on getting a larger operation going and running more than one pump going at a time, I think you will definitely want a 3 phase screw compressor. Keep in mind that each pump will draw about 25 CFM, so if you were running two at the same time, the compressor would need to deliver 50 CFM.
A compressor distributor can also help you with filters to help meet the air cleanliness requirements I mentioned above.
Thanks,
Dave
