Driven by a genuine 350W motor, it balances solid performance with quiet operation, keeping noise around 70 dB so you can fill cylinders without distracting your workflow.\u003c\/p\u003e\n\u003ch3\u003eKey design features that stand out\u003c\/h3\u003e\n\u003cp\u003eThe unit features a dual‑pointer pressure gauge and two‑level auto‑stop for clear, safe control as you approach target pressures. A compact water tank and a dedicated grease reservoir help manage cooling and lubrication, supporting longer sessions and more consistent fills.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFour‑stage compression for stable high‑pressure output\u003c\/li\u003e\n  \u003cli\u003eIntegrated water‑cooled structure to maintain steady performance\u003c\/li\u003e\n  \u003cli\u003eQuiet operation with a 70 dB sound footprint\u003c\/li\u003e\n  \u003cli\u003eDual‑pointer gauge and auto‑stop offer precise, safe fills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eReal‑world use and performance\u003c\/h3\u003e\n\u003cp\u003eIn practical terms, PCP setups benefit from meaningful efficiency gains during small‑volume fills. For example, filling a 0.5 L tank from 3000 psi to 4500 psi takes about 4–5 minutes, and a 0–4500 psi fill for the same volume takes roughly 14–16 minutes. A larger 6.8 L cylinder can reach 4500 psi in about 2 hours 40 minutes. The system supports up to about five hours of continuous operation under ideal cooling, making it suitable for extended sessions without frequent pauses.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e12V DC input supports car battery or household outlet via the included converter\u003c\/li\u003e\n  \u003cli\u003eBuilt‑in oil‑water separator reduces maintenance needs for everyday use\u003c\/li\u003e\n  \u003cli\u003eCompact footprint: 11.8 × 6.1 × 12.4 inches; weight ~29 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSetup tips and safety notes\u003c\/h3\u003e\n\u003cp\u003eFor the first use, fill the cooling circuit with about 300 ml of antifreeze to protect internal pathways; neutral antifreeze is advised in colder areas. Do not turn the grease knob during the first 4–6 hours of operation. After each fill, close the bottle valve, then vent the line to release pressure before the next cycle. For best results, follow the manual and consider a GX external filter if you need enhanced filtration performance.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What can the GX-PUMP GX-E-CS4 power?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It powers high-pressure PCP air cylinders and compatible air tools with 12V input and auto-stop safety.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How long can you run the GX-E-CS4 continuously?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Up to about five hours of continuous operation with its integrated cooling system.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"GX pump","offers":[{"title":"Default Title","offer_id":47469806813358,"sku":"B0BLSS8T43","price":1261.79,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/6012\/9710\/files\/gx-pump-gx-e-cs4-exterior.jpg?v=1770424743","url":"https:\/\/handyskook.ca\/products\/gx-pump-gx-e-cs4-portable-pcp-air-compressor-350w-5800-psi-water-cooled-5-hours-run-time-12v-auto-stop","provider":"HandySkook","version":"1.0","type":"link"}
