AZ OB2 comp. Any issues?

Hi there, Air-Zenith OB2 is a completely new design from the ground up. The valves have been redesigned into a totally different design so they are no longer mounted on the piston, this will prevent the valve from ever snapping off and if in the odd case one ever does break it has nowhere to go so it will not fall into the compression chamber and damage the piston ring wall or go out the output and damage your valves or check valve. The piston has been beefed the hell up so it will never bend break or get damaged. The bearing mounting system and design has been changed to prevent the problems from the past of a slipped bearing race. The air is no longer brought into the crankcase so the piston and bearings will never see dirt grit air or moisture, it is completely sealed for the absolute longest life possible for the rotating assembly. The new air input design also prevents the motor from being under vacuum this also keep dirt debris and moisture from being sucked into the motor., Last now the air is brought into the head fresh cold air is now being introduced along side the hot compressed air output this keeps the head of the compressor much cooler. The air filter has been redesigned to keep the moisture out of the compressor even better now, the Filter is also now remote mountable so in the event it toes go in a wet location it can be relocated to keep the input air nice and dry. The Fans on top now have a 100% sealed design this makes them 100% water proof, they even run under water ! haha Last the compressor has now been redesigned with an integrated thermal switch, this in combination with the pre wired relay will turn the compressor on and off properly to prevent the compressor from reaching temperatures where the valves or piston ring can get damaged or heat tempered. Finally the compressor comes pre-wired with the correct size relay and relay socket for easy wiring as well as easy replacement if the relay goes bad. I forgot the Motor, Almost 2 years of research went into the new motor on the OB2 a total redesign it is smaller lighter slower rpm, but way more torque this means a hela fast compressor with very little amp draw 35amps! Onto the case. Every aspect of the compressor body has been changed, there is not one original part on this new compressor, even the mounting feet have been built almost 2X as thick with special reinforcement ribs to prevent fracture when mounted on odd angles. The way the feet mount has been changed so you can rotate the compressor without having to take the compressor apart. If any other question shoot me an email to: paul@air-zenith.com or shoot an email to Doug Dehaven at tech@air-zenith.com We'll help you out!  Paul, Air-Zenithwww.air-zenith.com    

Nissan, check your ground wire make sure you have a good ground spot directly bolt to the chassis, move away paint or coat to expose bare metal and use large nut and bolt to tight down your compressor ground wire.  Ground wire is as important as your power wire, I suggested you run 4AWG wire from battery to compressor, compressor will perform better with larger wires!  If any questions please shoot me an email to paul@air-zenith.com  I will help you out buddy.  -Paul, Air-Zenith. www.air-zenith.com     ---------------------------------------------Originally posted by Nissan4x293---------------------------------------------Originally posted by BigMikeAtGaugeWe have sold quite a few allready with no complaints. I actually have one setup in the warehouse that we are going to run some test on after lunch today. I havent had anyone call with any questions about a BURPING sound. You are running adequate wire and only running the compressor while the engine is running?  ---------------------------------------------Hi Mike,It's running 6 gauge wire with the relay that came with the OB2 and an heavy duty 80AMP fuse to an optima battery, this worked well with the OB1, the "burping" happens even just running on battery or even with engine idle, even if I give it a little gas  while the engine is running, it still does it. My alternator is 90AMP as well. Thanks for you answer Mike, sounds like there is something wrong with my comp. But let me know if you hear some more about them, it would be greatly appreciated! Thanks! ---------------------------------------------

BUT what about the ground for the relay? Because right now we took the relay that came with the OB2 and installed it at the same spot BUT the relay was already grounded BEFOREHAND to the truck box, now my friend just realized that the red wire going from the comp. to the OB2 relay also has a black wire beside it and he thinks that this is the wire for the ground for the OB2 relay?? BUT during the installation, we basically crimped both red and black wires together then hook it to the relay which would mean that the OB2 relay is grounded twice and this could be causing our problem??Please let me know because tomorrow morning I intend to cut the black wire from the crimp and this time only the red wire will go to the OB2 relay and this should resolve my problem since that the OB2 relay was already grounded, what do you think? Hopefully this is the problem because I would like to keep this OB2, beside the "burping" it is working really well.  I will check the forum tomorrow morning because I'm too tired now!! Once again, thanks for all your help!!

i have the ob2 in my tahoe.it performs great. no problems what soever.i had 2 ob1 compressors in my cover truck and loved them as well.i got to meet Paul at sema through John Oneill.Paul was a super nice guy and very informative of his product.You can tell he is someone who stands behind his product just talking with him.Thanks for a great product and all your help Paul  ///TN JEFF 

My son went throught 3 OBD1's and he buddy as an gone throught 2 OBD2. I'm sticking with my VIAIR 5+ yrs has not missed a beat!!!

And i have a 5gal tank, running at 200psi, so they take a beating.---------------------------------------------
