Shop Air - Amax 2.5HP 24L Air Compressor

7/1/2018

I've been looking around for quite a while to replace my tiny Nardi Silverstone 2 Air Compressor. The Nardi works fine but it has only a 5L tank and the sound it gives out can be quite loud for usage at night when the compressor kicks in. For my work in the shop past 10pm, I've to switch to bottled air for chip clearing, which cost about $15 per bottle. I use up one bottle for each session in the shop, which make no sense as I've an air compressor sitting around.

Those silent compressors are way beyond my budget (Mike got a Bambi at SGD 800+ shipped and a pre-owned Jun-air cost SGD 600). The solution then was to find a fridge compressor to replace the compressor on the Nardi.

I did come across 2 discarded refrigerators within the last few weeks; one at my work place and one at the bin center next to my block.
Knowing too little except from YouTube and being too embarrass to be dismantling something from the bin center, I didn't take any action other than pics. Pride... 🙄

Today, I took the plunge. Terence has this contact selling the Amax brand air compressor at, I think, the lowest price in SG. Best of all, the shop is just down the corner from my work place. After getting the address from Terence, I went over to take a look, hoping that I can test the compressors out.

The shop uncle is a nice elderly man with great patience. He explained to me about the use of the 2 compressors he has in the shop and plugged them in to allow me to assess the noise level. I got excited with what I heard; much quieter than what I have with bigger tank. But what got me to jump in to bring one back is the price! The bigger of the 2 - 2.5HP with 24L tank, is almost SGD 100 cheaper than my Nardi! The sound level is given at "at most 58db", where my Nardi is at 73db. Capacity wise, it is almost 5 times bigger. From my search online, Horme is selling the same model at SGD 20 more and a shop at Kelantan Lane is selling it at SGD 90 more!

So, in less than 10 mins from entering the shop, I tow it back...

When I got home, I quickly took out the new air gun and hose I bought a while ago tonpreoare them for installation. Some teflon tape were used and adjustments made to the spring within the compressor fittings to allow the hose coupling to fit in all the way.

Couldn't pushed in all the way initially. Uninstalled the coupling and saw a stuck spring. Adjusted it to allow the fitting to seat all the way in, against a rubber o-ring inside.

Air was leaking out at the air gun's bottom. Added teflon tape on the threads of the fitting and solved the issue.

Look at the difference in size! lol...
I'll be putting the Nardi Silverstone up for sale soon. Should be selling at less than 50% of my purchase price. If there is no taker or the offer price is too low for me to swallow, I'll just remove the compressor and connect the 5L tank to the Amax, expanding air storage to 29L. It will be a fun project.
