    just installed my air regulator on the side... my water trap will be installed directly to my compressor? or should my water trap and regulator be next to each other?

    Reddy,

    4hp compressor will be good enough. In the shop we're only using 3HP Fuji compressor.

    You need to consider the sandblasting nozzle and media you will be using. There are several types of nozzle that will fit your requirement. Aluminum Ceramic Oxide, Tungsten Carbide and Boron Carbide. It has a corresponding service life. The best you can have is the boron carbide nozzle that has a service life of 200-1000 hrs (approximate service life).

    Here is the literature that will guide you in selecting nozzle. http://www.kennametal.com/content/da...Catalog_EN.pdf

    That's the company where we purchased our nozzle for sandblasting. It's cheaper to order in the US than Singapore.

    I've seen sandblasting equipment at Vic Steel in Aurora Blvd (near TIP) similar to this.

    Upgrade mo na lang yun nozzle niya. Im sure na low end yun nozzle na kasama sa package.

    Happy Sandblasting.

    Hi guys,
    I just wanted to add my 2 cents here on sand blasting. In Canada I had a 35 gallon pr minute shop compressor with a 7 1/2 hp motor. I could sandblast small parts, but not enough air for doing panels or rims etc. I also had a 150 cfm tow behind compressor with a 1 " discharge line. It worked fine for most jobs I had. What it boils down to is what you plan on doing, because a small 4 hp unit won't do much at all. Good for a nail gun and filling tires etc. I have a 2.5 hp compressor here and it won't even run with a plasma cutter. I do think the glass work will work out fine, because of the small nature of your projects. Sorry if I am throwing poor news your way, but this is my personal experience. Best of luck.

    The main breaker supplying the distribution lines at 60 Amps should be able to handle the entire load that it carries. Connecting the 4HP compressor to the main breaker directly is not advisable. Though the wire or line won't overheat, it won't cut-off or trip either due to the over capacity of the breaker rating over the load. My estimate for a 4HP motor more or less consumes about 24 Amps so it should pass through a smaller branch of about 20 Amps for it to be able to trip power just in case over current happens, say the motor overheats or seizes or the fan belt accidentally jams. The wire may exhibit a slight increase in temperature but at least it should be slightly warm to touch and safe enough to operate. Correct me if I am wrong about the exact rating figures but you get the principle behind it.


    Adding to what JayL said about dry air, the blasting media is sensitive to moisture so a modest Air and Water separator can help if you can't afford an Air Dryer.

    Welcome to the forum bro.

    When you can't bring the work to the blasting cabinet then this tool will work fine.

    Zendex Speedblaster









    A 3 HP 60 Gal compressor is good enough to drive the above blasting gun.

    If I was to think about serious sand blasting then I would get a compressor not smaller than a 5 HP 60 or 80 Gal double stage @ 175 PSI. The other factor to think hard about is how to keep the air dry. Moisture will wreck havoc on sand blasting as the media tends to cake .

    YUP bro that will do just fine, tamang tama ang laking wire mo and that gauge 10 can surely supply electricity to other power tools without any over heating of the wires.

    Good luck on sandblasting, Reddy. That seems like like new territory in this forum

    I am from Malabon, too. Lived in Longos and went to Tonsuya Elementary School.

    I know hat you mean about oxidation. My family used to repair and repaint our car every year due to corrosion. Hindi pa kasi uso nung araw ang rust protection .
