Can I use this compressor to check air pressure without being plugged in or connected to the battery. Thanks

Viair 40047 need to with being plugged in or connected to the battery. Please review the factory web link below for Viair 40047: http://www.viaircorp.com/400P-rv-auto.html Thank you Best Regards, GoAiring Customer Service

Hi, Chuck - Pittsburgh. Remember this device senses pressure and at a set psi value simply opens or closes contacts that apply or remove voltage to your compressors electric motor. It senses tank pressure through the bottom port and has a connection for your unloader line to allow easy restart of compressor. Above all make sure your safety pressure relief valve is in place, have a good one, Chuck.

yeah. that is how it works. the fan stays on while the compressor un-freezes. Sorry to hear you bought one of those. They are pretty lousy and low quality. Mine died after very little use just after the warranty ran out.

Sorry we have not used the air compressor part yet. We've used for light when we didn't have power. Also for jumping the tractor, motorcycle and cars. I can only say that it has worked great for that. Nice power to recharge our phones too.

The compressor has two standard 1/4" female coupler connections on the compressed air outlet. Use a standard 1/4" male coupler and push it in until it locks. To release, push the locking collar back on the female connection.With no air pressure, the connections work easily, with air pressure it is somewhat more difficult to make the connection.

This is a great off road compressor but does not have AC plug nor does it accept air powered accessories. It excels at putting air into tires quickly.

Battery is replaceable. Compressor hose is stored inside compartment on back. Hose does not detach. Air pressure gauge on back but suggest using your own tire pressure gauge to verify pressure. Jump start feature is great, also has cigarette lighter adapter to run phone chargers and so forth. The air compressor feature is nice, but is best reserved for emergencies rather than regular use for tire inflation. Takes some time to build pressure but works fine.

This unit is strictly a 12 volt DC powered compressor. If you wish to use this on house current, you will need to use a 12 volt DC power supply which could handle the required amperage. I would suggest a small car or lawn mower battery of at least 100 ampere capacity. Put a trickle charger on it and you would good to go. Most of these battery powered compressors will draw considerable current during operation and they will get hot so be sure to take care when operating and keep the compressor clear of any combustible items.

Yep. It simply regulates pressure. It will connect current at 30# and disconnect at 50#, through electrical contacts. Therefore not advisable to use where fuel or gas vapors may be present. I substituted the original air regulator on a Craftsman Air compressor with an identical unit.

You can get power for the main fused wire for the compressor directly from the positive post of the battery. For the other wire that turns the system on only when the key is on you must use a light probe and find a wire that is on only with the key. otherwise the compressor can run when it is parked and the height changes like you step up on the bumper. I also have a cab mounted gauge and kneel valve.

yes, but it must be a High pressure industrial duty air compressor. Just like the ones used to fill scuba tanks. Generally not available to the public.

This device must be connected to a compressor/source of compressed air. It is not a battery driven inflator.

Not exactly sure what you mean. If your talking about a mobile compressor like something you would take off roading I dont see why it wouldnt work just fine. No air is released until you squeeze the handle. On the other hand are you saying your compressor is continuous and has no relief?

Thanks to all the answers. I have an air compressor that plugs into the cigarette lighter but it is inconvenient to have the car running when I use it in my garage. Unfortunately there are no current specs on the compressor.

Only with an air pressure. You will need air compressor not more than 120 psi. It will not work with pressure under 65 psi. I got best results between 70 and 85 psi.

I am currently using this compressor for automotive air tools, and it powers everything I connect to it with no problem. If you are using multiple nailers off one compressor, you may need to check the usage on the guns to see if it exceeds the output of the compressor.

I don't know why not, I just measured the sound of an air compressor in a closed garage today, works great!
