Allereerst welkom hier op het forum, ik zie dat het je 1e post is!

Deze oude airco-installaties zijn voorzien van het R12 gas. Helaas is dat niet meer te krijgen, aangezien die milieuregels ernstig aangescherpt zijn. R12 is een nogal vervuilend gas.
Vaak worden oude R12 systemen omgebouwd naar R134a, zodat je dat nieuwere gas kunt gebruiken. Dat kost helaas wel aardig wat geld.
Ik heb mijn airco zo'n 2 jaar geleden (ook nog een R12 systeem) laten afvullen met R413a. Dat kan zonder problemen in een oud R12 systeem, zo hoef je het systeem niet om te bouwen.

Wel bijzonder trouwens, een 83-er met airco! B)

Er wordt door de airco bedrijven een slaatje uit geslagen voor de ombouw van R12 -> R134a.
Het is niets anders dan de twee aansluitnippels die vervangen moeten worden en ander gas erin.

Maar een normale vulling incl vacuümeren kost al gauw 100 euro.

Bij elk airco inbouw bedrijf kunnen ze aan de nippels zien welk gas erin zit.

Hoi G beekhof ,als je een nippel hebt met schroefdraad kan er r12 gas in en als je nippels heb waar je een slang op moet klikken dan is het voor r134 a gas . Ik doe zelf al jaren airco,s omdat het mijn vak is ,maar om een instalatie om te bouwen van r12 naar r134 a gas zou je voor het goeie als je al geen lekkage heb alle rubber verbinding rubbers moeten vervangen en natuurlijk de filter droger . dan het systeem goed doorbazen met stikstof waarna je in pincipe kan gaan afvullen met eventueel een toevoeging om je restand r12 te neutralisieren . zelf moest ik indertijd de pomp vervangen omdat deze defect was maar ik draai nu al jaren met r134 a zonder problemen en het is eenvoudig bij te houden voor mij omdat r134a goed te verkrijgen is succes met je klus grt hans
