    Default Air compressors

    I am looking to buy an air compressor for home, DIY use. I have 2 main uses, dusting stuff off and using a brad nailer. I would like to later use the same machine for sanding (wood), die grinder and small paint jobs (like furniture or the odd metal fabrication).

    The one feature it must have is that it needs to be relatively quiet - I don't want to annoy the neighbors and a regular noise in the garage will get too much.

    I have seen this one from Adendorff:

    Not sure if this is any good though.

    Advice and other compressor suggestion would be helpful

    That machine will easily "dust off stuff" and a brad nailer sips air too. Spinning tools use LOTS of air so a die grinder or sander is going to keep that machine very busy.

    I have not tried a silent compressor, but belt drive is quieter than the small direct drive. Air tools including painting use a lot of air. bigger is always better. I found a 50ltr much worse than the 100ltr i have now. it tends to run the motor a lot less, hence less noise.

    i am in a complex and keep the compressor in the garage. No issues so far. Once you have a compressor you tend to get more pneumatic tools as they are cheap and good so bear that in mind.

    Get the biggest you can. You cant spray a car with a 100l direct drive without having to wait a bit.

    That oil free one you show won't be good for a die grinder and other rotary tools, it will be running full cycle and will wear out quickly.

    Rather get a piston type head and go for the biggest tank you can afford, even if it means buying a used machine off Market Place or similar is my advice.

    If you want to operate any air tools you need a compressor that can deliver at least 8CFM. Non of the direct drive compressors can do that kind of cubic feet per minute.
    To save floor space in a home workshop look at the vertical tank 115l compressor from Ardendoff. I've run on for about 5 years without any problems. https://www.adendorff.co.za/product/...ve-compressor/

    Nothing wrong with the air output of that direct drive unit.
    Its light duty cycle, small footprint and low noise suits your application.
    If you need to upgrade in future, just link the 40lt cylinder to a larger one (second hand, ceiling mounted?) with a properly swaged high pressure hose that can be made up at many suppliers.

    I was at Adendorff the other day and saw this one there, unfortunately @ ~R7000 its just out of my budget.

    Look on Marketplace, sadly, there are so many places going under due to Covid that you should rustle up a bargain.

    I am no expert, but I have always found the belt fed compressors to be much quieter than the direct drive units. I have not done this analytically with a Sound Level meter, but subjectively they do seem much quieter to me? Perhaps I was using the wrong brand?

    The lower sound frequency and vibration emitted by belt driven piston compressors are amplified by concrete floors and permiate masonary walls with relative ease. This is not the best option for the op's discreet use within a built up residential area.

    However do agree with you, I would take a rumble over a whine anyday ;-p

    Rubber pads under the feet, or a separate frame with rubber mountings might mitigate a lot of that noise.
