Take a look at Falch high pressure cleaners. Higher pressure, and more important, much higher waterflow.

They are available in Thailand trough Siam Road Safety.

The top pump produces 3.000 bar at 24 liter/minute.

They have also smaller models, like 300 Bar at 20 liters a minute. Special the high flow rate makes a big difference with cleaning.

Will that pressure take my glass coating off ............. and my paint. Do they have adjustable pressure at the unit? I didn't find that their web site worked well ... I got a 403.

Think I'm into the VIP Blue, http://www.singsanguan.co.th/uploads/downloadOne_file/1386929397.pdf but thanks anyway.

You clicked wrong, try this: http://siamroadsafety.com/en/products-technology/falch-waterjetting-systems/the-world-of-waterjetting

You can also visit the Falch website, falch.com

All pressure cleaners have adjustable pressure. But if you reduce the pressure, you also reduce the waterflow. Unless you mount a different nozzle. Then the pressure reduces, without reducing the waterflow.

Wow Arjen, them's are some mighty big pressure washers

I'm not sure if that's the kind of thing JAS21 has in mind to wash his car and clean his AC's

Does anyone know of a place in West Bangkok/Nonthaburi that repairs Karcher  Pressure washers other than the Karcher company itself please.

KTW is the importer of Karcher to Thailand. They have access to parts. Perhaps some of the dealers who buy Karcher from KTW can get the part you need. I am curious why you would not see your Karcher repaired by the company that imports and distributes Karcher in Thailand?  I would be very hesitant to see any alternative brand parts go into a Karcher Pressure Washer.
