Richtek Portable Digital Air Compressor / Tire Pressure Cont

[Chuppychup]

Thanks for answeinr my questions man Ditiang.

 

So does it work just like at the petrol station ? Meaning when u insert the noozle into the tyre value, it shows the current pressure, den do you get to set the pressure you wish to pump ? I.e if you set at 240kpa, it pumps until 240kpa ? it wont over pump right ?

[Ditiang]

Petrol station most of them are digital type showing LCD number.

 

For VIAIR 85P, this is not a digital pump and cannot set the pressure.

 

This is how it works:

 

When you insert the nozzle into the tyre, the meter will start to point at the tyre current PSI.

If example now your PSI is 30PSI and you need it to go to 33PSI.

1) On the pump while you look at the meter.

2) when you on, the meter start to go up

3) When about to reach, switch it off and read the meter.

4) not enough pump again

 

As for me, 2 sec it pump up 2PSI.

So got to play with it a bit and practice :)

Thanks for the review.

I'm looking to buy a pump and this looks good.

However, I read that some pump blow the fuse bcoz it needs 15A type.

Do you have trouble with the fuse ?

 

Or better to get one that direct connect to the battery via clips

[Ditiang]

Yes I also did read the review of the fuse being blown.

The reason is that people use it the wrong way.

I came across a review at Amazon regarding about this.

He also afraid of the fuse being blown.

So he contact the VIAIR supplier about this.

 

The answer from them is that you got to "ON" the engine 1st, then insert the socket into the 12V cigarette hole.

After that you can turn on the pump. Once all 4 wheel pumped, turn off the pump, remove the socket from the 12V cigarette hole and off your engine.

The reason of fuse blown is there are people insert the socket into the 12V cigarette hole then on the engine.

One shot too many power rush into the socket and blown up the fuse.

 

You can get the VIAIR 88P.

Direct connect to the battery via clips.

But remember to read the spec of the product before you buy.

Hi all, i would suggest using these portable air compressors for emergency situation only.

 

For a very good reason that the air inflated is WET and over time you'll get water inside. And that leads to internal rim corrosion, to both steel and aluminium materials.

 

My car came with a compressor too, it is useful when you encounter a slow leak. Just pump up and go for repair.

 

Continental tyre developed such compressor too. All the cables and hoses concealed within the container. Came together with the leak seal liquid. I know they are available from Stamford tyres or YHI.

One question.

 

If using hand/foot pump, how would you know you hit the correct pressure?

I had been using those single-barrel foot pump for 3yrs. I use a separate dial pressure gage to check the tire pressure.

Every 2 weeks, I routinely check the tires pressure, which usually drop about 10 kPa. After some time, I know that I need to step on the pump 30 times to "add in 10 kPa". After this I will check with the pressure gage again, and bleed off any excess pressure [or top up by pump a few more steps].

 

However, I stopped using the foot pump eversince I changed my 4 tires recently. When the pump nozzle is latched onto the tire valve, air is leaking from the valve. The tires deflated instead of being inflated. The tire shop said that the tyre valve is standard size, and likely the foot pump nozzle wear out.

Those selling at NTUC at about $5 each?

[Ditiang]

I wonder those tai-tai who drive BMW, Mercedes, Luxes and audi got ever think of pumping their tyre a not har?

Cos this type of technical issue normally they will not know or care about it.

I bought mine from Autobacs, forgot the price, not expensive. Should be same as those NTUC type, check the pressure on the package.
