  • all about Air Compressors

    I recently got myself a Vespa 2hp compressor and learned a lot on how to correctly choose the correct one since there are countless imitation.

    the motor specs...

    and comes equipped with safety features...

    the overall specs...

        tomorrow, I make sure the pulleys are aligned and tightened as preferred.

            Thanks Doc, I hope your health is improving... we always include you in our prayers.

            going back to the tweak. the most difficult thing to do on the compressor is adjusting the belt. it is also one of the main causes of noise and vibration. I did try to tighten the belt and in doing so saw the motor and pulley to be out of square. hmmm, no I know why there is so much noise (though not loud).
            first I saw the pulley locking screw is made of the ordinary ones you find (maybe the cheapest) and it is terribly bent out of shape.

            I removed it and replaced it with a stainless equivalent.

            after an hour of trial and error, I gave up and thought of a better way to tighten and align the belt.
            I first drill two 5/16" holes on the adjustment bar underneath the motor.

            then mounted two scrap piece of angled bar (forgot the term) to align with the holes I made.
            .

              added the screws and nuts...

              now it aligns much easier and gets the belt tightened to previously unachievable tightness.
              I still want everything to align perfectly, but for now I have to wait till Friday to borrow the laser level...

                Nice mod Timb. I bet you can align the motor now without much pulling and pushing. Have you found the replacement belt too?

                How long are the adjustment screws?

                The stock screws on the mounting base are also crap. I broke one in half while aligning my compressor's motor.

                      Re: all about Air Compressors

                      guys im planning to buy a compressor...
                      i want to use it sa bahay lang for tires ng kotse...

                      ano po difference ng belted sa direct coupled?

                      in the future i want to do some home diy jobs.. like some painting...
                      kaya napo kaya ito ng 1/4hp?

                      medyo malaki po difference ng 1/4hp sa 1/2hp eh

                      the ones i saw are:
                      vespa belted 1/4hp 36litersaround 4500 (bnew)
                      vespa direct coupled 2hp 25litersaround 6t (bnew)
                      spear and jackson direct coupled 1hp 6liter 3.5t (xgood from australia)

                      which is best buy kaya?

                      why mura po pag coupled
                      pwede naba 1/4hp? or should i invest for a better one?
                      what gadgets do i have to buy? gusto ko po sana yung baril... para pag may lilinisin ako baril baril nalang..
                      primary purpose ko lang naman is to inflate tires... madami nako nasisirang portable... malaki na nagagastos ko sa mga portable.. hehe

                        another compressor thread - target is automotive air tools

                        hi,

                        i got a few hits pertaining to compressors on his board. very informative i should say.

                        now, another question of my own. does hp rating of the compressor relate to the cfm?

                        i am planning on getting vespa from ey as suggested by JayL. my target use of the compressor is air tools - 1/2" drive impact wrench, 1/2" or 3/8" ratchet, die grinder, and sander.

                        - is 2 hp enough for this purpose? i bet what's needed for air tools is something more that what is required.
                        - what wiring should i consider for powering the compressor? gauge? and breaker rating? obviously i'll be lining up a new one for this

                        Comment

                          Re: another compressor thread - target is automotive air tools

                          I would not go lower than the 2 HP Vespa and bump it up from the factory 100 psi pressure setting to 115 psi then regulate &/ filter ( moisture ) at 90 psi output. Enough to drive the Impact Wrenches and Air Ratchets. The air die grinder and sander would be another story. These would run but at some point in the job you'll have to wait for the compressor to fully charge to get the tool's full working capacities.

                          You can cheat though in order to get more run time. Wait for the compressor to charge and just before it reaches the cut off point start the tools and run the compressor at 100% duty cycle till it can't cope up anymore. Then wait again and repeat the cycle. That's what I do till I get another to 2 to 5 hp compressor to connect in series with my current one.

                          Hope this helps.

                          Try Best Achievers maybe they can give you a better deal. I got mine from them as well as the 2 hp I have at Autospeed.

                            nowadays, what's the score with the 2 hp vespa's?

                            where's best achiever's?

                            would it help if a larger tank would be used?

                            how do you spot a fake vespa from that of the original one?

                              average CFM (cubic ft/min) 25% duty cycle @ 90 psi

                              1/2" drive impact wrench - 4.5 CFM
                              1/2" or 3/8" ratchet - 4 CFM
                              die grinder - 6 CFM
                              sander - 7 CFM

                              *Those are estimate CFM ratings only. Check your tools for actual CFM.

                              @spyghost

                              Selection a compressor will depends on how will you use the tools. business or hobby?

                              If hobby for sure one at a time lang ang gamit mo ng air tools. You can use, for example:

                              Powercraft air compressor vertical type

                              Motor power input: 2.5 HP
                              Cylinder head: 2 X 65mm
                              Airflow: 9.0 CFM
                              Working pressure: 85-115 PSI
                              Tank Capacity: 115 Liters
                              Motor Speed: 1100 RPM

                              If you will use Vespa check mo na lang yun compressor rating sa nameplate that will satisfy your requirement.

                              Also critical din yun air tools working pressure dapat pasok din sa working pressure ng compressor mo.
