| 1446968 | 2018-03-04 00:14:00 | Vacuum cleaner = ESD Sigh..... Explain how. I have done this for years. It is plugged in you know, albeit switched off, and therefore earthed. |

| 1446969 | 2018-03-04 01:17:00 | The vacuum maybe earthed but static is caused by the friction generated by air and dust rubbing against the tube/hoses. A brush could also generate static from the bristles, nylon be the worse but even animal hair could alao become statically charged. However, components are quite well protected, using an anti static silicone, which shield it quite well except for the contacts. Else components would fail with the amount of dust build up and fan movement. It really depends on whether you want to risk it or not, it'd be safer to not do it but the probability is very slim these days too. Either way, blowing/sucking both have the ability to cause static, so do it at your own risk. |

The hose does not conduct back to earth, yet can build up a charge. This was demonstrated to me when I was trained as a computer technician. Oh and by the way... Sigh right back at you. |

| 1446971 | 2018-03-04 02:55:00 | Just use a cheap air compressor from Mitre10 /Bunnings ( cant remember which) about 10 years ago, cost about $150, put on an air/oil filter, you can adjust down the air pressure so as not to damage any components, It also has a lot of other uses, like blowing up the tires on the wheel and sack barrows, other cleaning and sometimes even the odd small spray paint job. | wainuitech (129) | ||
| 1446972 | 2018-03-04 03:06:00 | It wouldn't be very difficult to modify a small old out of date cng gas cylinder and fittings to take a filler valve and an outlet with hose and air gun, to use as a portable air tank, pumped up to about 100 psi?? You could then use one of those small 12 volt tyre inflators, run off an old PSU which I do for tyres and wheel barrow etc, to pump it up. Main cost would be the hose and air gun. |

| 1446973 | 2018-03-04 03:09:00 | Maybe cheaper just to buy a blower for the price of a couple of cans? www.youtube.com |

| 1446974 | 2018-03-04 03:30:00 | Whilst on the topic of dust, does anyone know if it would be worthwhile wiping fans blades with antistatic wipes or spray, or teflon spray, would it work last to prevent dust sticking ?? | Terry Porritt (14) | ||
| 1446975 | 2018-03-04 06:43:00 | As linked above are the hand held electronic air dusters - basically a mini blower. Similar to some larger garden blowers But there are also the 18 V drill shaped blowers/Tyre inflators. Ryobi has one here (www.homedepot.com) (cheap at home depot) Don't seem to be any here in stores. PC suppliers ought to have something similar. Simple hand pistol type rechargeable blower...rather than messing about with vacs, floor blowers, compressors, cans, etc... |

Can happen filling your car too.... It's EARTHED. It's why you always earth it when building them, never mind cleaning one. And earth means just that, not some dumb bangle round your arm connected to nothing that I have seen techs do. When you vacuum, leave it plugged in. Also, you don't shove the cleaner right in it, you'd like damage a capacitor or diode or two, you use the brush and the vacuum sucks up the dust as you brush it out. So yes, sigh. |

Sigh you obviously fail to understand the voltages involved and the source of the electrostatic discharge. Just because you are ignorant of this doesn't mean that it is not a threat. OK :) |
