GX PUMP E-5K2 High-Pressure PCP Air Compressor
Category: GX Pumps

Powerful Compression and Reliable Performance
-
2 Pistons & 4 Stages Compression: This compressor features a unique dual piston and four-stage compression technology, specifically designed by the renowned GX pump brand. This innovative design significantly reduces fill time, allowing you to reach a maximum pressure of 40MPa (5800psi) in a matter of minutes, typically just 2 to 3 minutes for a rifle.
-
1200W Max Power Capacity: With its powerful 1200W motor, this compressor can handle large PCP, paintball, and scuba tanks, even those exceeding 20L. Note that scuba use is not certified, and an additional burst disc may be required if filling over 5000psi.
Efficient and Safe Cooling System
-
Water + Fan Cooling System: Equipped with a water cooler and a powerful cooling fan, this compressor ensures efficient temperature management. The water capacity is high, and the high-efficiency water pump, combined with a radiator, maintains optimal operating conditions. A side indicator shows remaining water levels, and you can simply add water by opening the water tank cap.
-
Important Notice: Ensure you add 500ml of automotive coolant to the water tank before use. Do not operate without coolant; it can cause significant damage to the compressor.
User-Friendly Features
- Two Stages Auto-Stop Setting: The compressor is fitted with a twin indicator arm in the large, shock-resistant pressure gauge, making it easy to set the automatic shut-off point. When the desired pressure is reached, the machine will stop automatically. Additionally, the compressor will bleed off all moisture post-filling. This convenience allows you to pursue other activities while the compressor operates.
Super Fast Filling Speed
- 6.8L PCP Tank: Filling from 0-4500psi takes just 45 minutes, and from 1000psi to 4500psi takes 2.5 minutes for 0.5L, and 1.6 minutes for 1L. For 1L from 1000-3000psi, it only takes 3.5 minutes. Rest assured, we hold a patent for this compression method, USA Patent No: US 9,726,165 B2.
Enhanced Lubrication System
- Grease Injection System: The compressor includes a pre-installed grease tank, but no spare grease needle is included in the package. After use, we recommend using food-grade E.P. grease. Do not turn the tank for the first 50 hours to prevent excessive grease buildup, which can affect air quality. After 50 hours, you can turn the tank two-thirds of a revolution.
