POWER SOURCE- 24-VDC AMP DRAW- 40 amps DUTY CYCLE- 80% - 8 out of 10 minute runtime @ Temps under 90 Degrees F. MAX PSI- 150 psi CFM** @ 50 psi 12 scfm CFM** @ 100 psi 6 scfm THERMAL PROTECTOR- Our thermal protector will shut down the 24-Voltair when the motor exterior case reaches 200F. This is a auto-reset thermal protector that will reset itself within 20 minutes. OIL CAPACITY- 473mls OIL RECOMMENDATIONS -20F - 70F use a 10W non detergent compressor oil 50F - 110F use a 30W non detergent compressor oil -20F - 110F use a 40W synthetic non detergent compressor oil ** SCFM is a number that can often be misleading. The 24-Voltair is capable of filling a 10 gallon air tank from 0-150psi in just 3 minutes. Battery facts 1. The OEM (Original Equipment Battery) that came with the purchase of your vehicle is only designed to keep up with the demand of the vehicle. For optimum performance, Voltair recommends replacing your battery with a battery that is rated with 120 or more minutes of reserve. 2. The alternator that comes standard in most vehicles will charge between 40-50 amps at a vehicle idle. Since the Voltair draws 80 amps when in use, Voltair recommends a good battery and in some cases a second battery may be necessary. 3. Voltair recommends a battery with 120 or more minutes of reserve. The 12-Voltair air compressor does not need cranking amps for optimum performance, but it does need battery reserve. 4. Over time a battery’s ability to hold a full charge greatly diminishes. A lead battery may need to be replaced every 2 years and an optima battery may need to be replaced every 4 years. 5. If you are using or planning to use the 12-Voltair for more than 3-4 hours on a day-to-day basis adding a second battery will help in achieving optimum performance
