After certain amount of used or hours?** A: the instructions say to use distilled water, so you should check it and keep it topped off, but it should not need to be changed unless you see impurities in it **Q: Can you use this for mini 1.9l or full size scuba tanks and is an adapter required?** A: The manufacturer states you can fill a 6L tank and it can run 5 hrs. Continuously though I only used it to fill my 90ci buddy bottle. I never timed it but it takes about 15 min. To top my bottle off from 3k to 4.5k and works off car battery as well so topping off my tank at the range is a breeze **Q: How to get tech support about antifreeze leaking out the bottom after 1 fill?** A: I would just take the cover off and look for a loose hose clamp. ## Frequently Bought Together - GX PUMP CS4 Portable PCP Air Compressor, 350W Powerful Motor,Max 5800Psi/40Mpa, Water and Fan Cooling, 5 Hours Continous Work, 12V Auto Stop Paintball Air Compressor - Creation Core High Pressure PCP Hand Pump Air Filter Water-Oil Sparator with Female and Male Quick Connect for High Pressure Air Compressor Pump 30Mpa Blue - Maddog Paintball Airsoft Fill Whip Hose Extension 4500 Psi PCP - 36 inch Stainless Steel Charging System --- ## 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.com.om/products/504048138-gx-e-cs4-pcp-air-compressor-350w-powerful-motor-max](https://www.desertcart.com.om/products/504048138-gx-e-cs4-pcp-air-compressor-350w-powerful-motor-max) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-08-14*
