If so, how much air does it consume?** A: Yes should be connected to an air compressor. The pressure range is specified in the manual that I don't remember the exact number, but my small compressor worked just fine. **Q: This being a german tool, is the quick coupler a na version or european?** A: I gobbled one together to allow it to work, but no longer have the vehicle. If anyone needs the wand with a connector that allows yo to get from Swedish to USA standard fittings, I can help. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Klima geht wieder Gut. *by on Reviewed in Germany 16 August 2025* Kein Gestank mehr.

Gerät ist sehr Gut. ### ⭐⭐⭐⭐⭐ Perfect for a/c cleaning *by on Reviewed in the United States 21 July 2022* Highly recommend getting this one for a/c cleaning ### ⭐ Don't waist your time *by on Reviewed in the United States 26 January 2026* Sent product back because it is almost impossible to get the disinfectant solution to use with this gun after several attempts. Should be sold together or not at all. The seller expected me to pay postage to return the product, it was never even opened, and it took forever to get my money back. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/51767573-liqui-moly-4090-air-conditioning-system-cleaner-gun](https://www.desertcart.sk/products/51767573-liqui-moly-4090-air-conditioning-system-cleaner-gun) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-25*
