Bit off topic question, not directly woodworking…
I have some doors which I have to paint, with latex interior paint.

Can I use my HVLP sprayer for that ?
I guess the paint would have to be diluted with water, make a bit less thick ?

This is the sprayer set I have :

According to the link you posted, you have a 1.8mm tip. That should work. Be sure to test on a scrap. Also, be very careful diluting with water. Look to the paint manufacturer for max dilution. It is usually 10% or less. You can use floetrol with better results.

1.8 mm might get you there with some paints, but not all . As gw says , be carefully how much you dilute paints. You can certainly add enough thinner ( floetrol IS NOT a thinner ! ) to get it to spray through your gun. But at that point you have ruined the properties of many emulsion paints. Most are in the neighborhood of 10% thinner max.

Floetrol is a conditioner that allows the paint to dry slower and level out.

What kind of compressor do you have that delivers clean , dry air 9 cfm at 30+ psi ?

Bottom line is try it, though HVLP is not really the tool for spraying latex house paint.

IME – Never had any luck with latex in a gravity feed HVLP, without using largest 2.2-2.5mm tip.
Even with big tip, need a maximum recommended amounts of water to thin the paint.

A turbine, pressure cup, or pressurized tank HVLP with 1.8-2.0mm tip works much better. Can rent a Graco airless unit made for spraying latex, at reasonable price for small 1-2 day jobs. Used an inexpensive HF pressure tank gun for several 2-3 gallon projects using floetrol and water thinning.

Best Luck.
