Q: How well will this work for using this to paint vehicles?
a year ago- A: The CAT-20040C model will maintain 12.4 cfm @40 PSI which will satisfy many HVLP (high volume low pressure) spray gun operations for painting vehicles/panels since many paint booth professionals set spray guns @30-35 PSI. However, if your HVLP gun has an operating cfm closer to 13.5 cfm @30 PSI then we would suggest our 60 Gallon CAT-60040CAD model. Please check the operating specifications on your HVLP gun. The CAT-20040C & CAT-60040CAD compressors both have a pressure regulator knob and output gauge so you can set/regulate the output pressure right on the air compressor. NOTE: We do suggest the addition of an in-line desiccant air cleaner/dryer (i.e. PA208503AV CAMPBELL HAUSFELD, etc.) between the compressor and your HVLP gun to dry the air ~85%; this will help maintain the integrity of the spray paint/coating.Anonymousa year agoHelpful?
Q: what is the duty cycle?
2 years ago- A: The 20040C has a duty cycle rating of 70/30 (i.e. may run continuously at 5.3 cfm @90 PSI for up to 4 hours, or intermittently 30-40 minutes at a time at 10.6 cfm @90 PSI).Anonymous2 years agoHelpful?
Q: In the description it says "Low amp draw - 14 Amps - 220 Volts 60 Hertz" however in the specifications it says "110 Volts" I could be wrong but this doesn't make sense to me.
2 years ago- A: Yes, this is an error. We will update the listing to state 220 volts (60 Hz, 1-phase). -Thank you for bringing to our attention. ;)Anonymous2 years agoHelpful?
