GX Pump GX-E-CS2 Portable PCP Air Compressor — 4500 PSI, Oil-Free, 12V DC / 110V AC with Converter

Overview

Meet the GX Pump GX-E-CS2, a portable high‑pressure PCP air compressor designed for fieldwork, hobby projects, and on‑the‑go inflations. Capable of reaching up to 4500 psi (300 bar) with a swift 2700 rpm inflation rate, this unit packs power into a compact 6.7 kg body. Its rugged, travel‑friendly design makes it a practical companion for a range of uses where reliable compression and ease of transport matter.

Why choose GX

• Patented compression method with roller bearings reduces wear and supports longer service life under high pressure.
• Oil‑free and water‑free operation for clean, low‑maintenance performance.
• Built‑in cooling fan helps manage heat during longer inflations, contributing to consistent results.
• Lightweight and compact, enabling easy transport to the field, workshop, or range.

Powering options

The GX-E-CS2 is versatile: power it from a 12V car battery for on‑the‑road inflations, or use the included 110V AC converter for home or shop use. The dual power approach broadens where you can work, making it suitable for remote sites and urban setups alike.

Performance and practical use

Inflation speeds are designed for efficiency: in controlled tests, 0.5L containers inflated from 200 bar to 300 bar in about 8 minutes; from 0 to 300 bar in roughly 18–20 minutes. The device is optimized for tanks under about 60 cubic inches and may not be ideal for larger scuba cylinders. Verify your tank size and connection compatibility before use.

What’s included and important notes

• Oil‑free operation minimizes mess and simplifies upkeep.
• Built‑in moisture‑oil separator (extra filter included, uninstalled) helps keep intake air clean.
• Patented compression method (US Patent 9,726,165 B2) geared toward efficient high‑pressure performance.
• Note: CS2 is a manual shutdown version; it does not auto‑stop at a set pressure. Monitor pressure growth and shut off manually.
• Output fittings include M10×1 nut and 8mm quick connector; confirm compatibility with your equipment.

Tips for safe, effective use

After inflation, release the bleed valve before powering down to avoid pressure buildup. Store in a dry place and inspect connections regularly. The unit prioritizes portability, so plan your setup to keep hoses and connectors secure during transport.
