Thread: Any easy way to get the EAS pump to run without the engine running?

I made a jumper lead that I leave inside the fuse box. It allows me to jumper the relay when the mood takes me. Are you wanting something more permanent? Then run a separate feed off the battery to the pump, activated by a switched relay.

No I'm not needing anything more permanent. Just I've had occasions where I'm at a camp site and want to re-inflate the tyres but don't want the engine or loud tyre pump running. So your idea sounds good to me. Not sure why I didn't just think of putting a jumper on the relay.

Also, try not to laugh.... But I am thinking about using a nail gun on the weekend and don't want to move an air compressor. Easier to hook up to the outlet I have for the the air tank. Hoping the flow is enough, which I think it will be for a nail gun. I know the nailing frequency might be limited as the tank will run out but I am not constructing a whole house ha ha.

Check your operating pressures first, you'll get more shots out of the tank if you got a regulator and set it so that it gives you just enough oomph to fire the gun.

I personally don't reccomend regularly using the on board oem compressor using for alternate duties like tyre inflation or running small air tools. You'll find yourself pushing the compressor past its normal duty cycle which shortens the ring and reed life.

I don't have any plans on using it regularly. Its a backup system for other uses. I use a decent tyre pump that has far greater sustained flow and cheaper for tyre inflation. But in saying that the EAS tank is a backup for that and I have all the fittings just in case. Also handy for cases where I need a high flow of air to say pop a bead on a tyre although I haven't used it for that yet. So everything generally gets used for this intended purpose.

Be careful drawing amps with the engine off. It'll draw about 20 amps. I've installed a second tank alongside the first, for occasional pumping duties. About to fit a Viair standby compressor as well.

I'll keep that in mind but in the odd case I use it, I'd be lucky to draw any more than 10Ah (half hour pump time) which on a system with a 75Ah starter battery (non deep cycle) and 110Ah AGM deep cycle its not likely to do much harm huh? I know its not good to flatten any battery too much, even the deep cycles though.

Edit: Those Ah ratings are for lower current draw situations so I guess it's slightly worse than it looks above. My secondary battery is actually 105Ah and will last 170 minutes @ 25A until it reaches 10.5V. But that's dead flat just operating off the deep cycle which is something I don't want to do too often.
