Air Compressor Duty Cycle Question
I have a 5 gallon twin tank and although its a relativley small tank it
has a fast recharge time - about 15 seconds for it to go from when it kicks on until it reaches just around 145PSI. In the manual it states that the compressor has a 50% duty cycle. Am I understanding this right to mean that if my compressor recharges for 15 sec then I need to let it idle for a minimum of 15 seconds before it should be kicking on again? Thanks, -Brent |

yeah that about it. you can add a larger oir extra tank. most small
compressors dont get to 145 pounds what are you using? |

Thanks, -Brent More a matter of no more than 30 minutes run time per hour. Less on a hot day and maybe more on a cold day. -- Joseph Meehan Dia duit |

I think it may be a relabel of something else, since I got it as Costco (about 3 mo. ago). Cast iron oil-lube, its louder that I'd like, but I just stick it in a large closet in my garage and its muffled pretty nicley. That restricted air flow will also reduce its effective duty cycle. It has a 150psi max, 5.6cfm @ 90 PSI, pretty good for a portable 5 gallon. Thanks, -Brent -- Joseph Meehan Dia duit |

If it runs 15 and is off 15, you have 4 starts per hour. If it runs 1 minute off, one on, you have 30 starts and a lot of strain. |

Air Compressor Duty Cycle Question
What exactly is the danger of having the compressor running in a my
closet? Are you concerned that the heat generated by the compressor will increase the ambient air temperature to level that will cause the compressor to overheat/lose efficiency, or that the lack of or slowed air exchange will somehow cause the compressor problems. Bear in mind its not a coat closet, its roughly 4' x 10' and theres about a 1" gap at the bottom of the door, hardly air tight.

Yes, Heat is the primary determining factor for duty cycle. Bear in mind its not a coat closet, its roughly 4' x 10' and theres about a 1" gap at the bottom of the door, hardly air tight. Compressors make a lot of heat. It is not just the motor, but compressing the air makes it hot so that heat will also be trapped in there.
