- 3.5 Stage High Pressure Design: The GX pump's exclusive design compresses maximum air from each stroke, resulting in fewer strokes needed to fill air guns and reduced power consumption compared to traditional pumps. For instance, inflating a 500cc tank from 1000PSI to 3000PSI requires approximately 350 strokes, while a 200cc tank needs about 140 strokes.
- Oil-Moisture Filter: The pump features a filter that eliminates over 90% of moisture, ensuring dry air for inflating scuba tanks. The filter's blue desiccant turns red when it needs drying, following guidance in the user manual for maintenance.
- Durable Quality: Constructed with a stainless steel body and rubber handle, the pump is designed for stability and longevity, capable of enduring over 15,000 uses. It can maintain performance for over 2 hours at 200 bar pressure.
- Specifications: The pump has a general output nut size of M10*1, an 8mm wide quick connector, a maximum pressure of 310 bar (4500 psi), weighs 3.1 kg, and measures 62cm (24.5 inches) when closed and 105cm (41.3 inches) when open.
- Usage Instructions: Avoid adding oil or grease upon receipt. If needed in the future, pump 100 strokes without connecting to any tanks to prevent oil leaks from the pressure gauge. Included: GX PCP Hand Pump, user manual, and accessory kit.
