Core Features

Air-Driven Labor-Saving Operation: Automatically runs when connected to an air compressor (0.28-0.86MPa), eliminating manual handle pressing. Reaches working pressure in just 20 seconds with efficiency 3 times higher than manual pumps.
Dual Flow Output: 850ml/min under no-load for quick tool filling, automatically switches to 170ml/min when loaded for stable operation with ≤2% pressure fluctuation.
Large Capacity Reservoir: 3200ml capacity supports 10 hours of continuous operation. High-strength engineering plastic construction is 50% lighter than steel with superior corrosion resistance.
Wide Compatibility: Standard NPT threads (1/4" input, 3/8" output) with 98% tool compatibility. Stepless pressure adjustment from 0.28-0.86MPa for various high-pressure tools.

Application Scenarios

Engineering Site Repairs: Supports 8+ hours continuous operation for hydraulic breakers and equipment maintenance without refueling.
Industrial Assembly: Precision pressing operations with ≤0.1mm error for heavy component assembly in manufacturing.
Heavy Vehicle Maintenance: 70MPa pressure for stable support during chassis repairs on trucks and engineering vehicles.
Outdoor Emergency Repairs: Compact size (340*210*215mm) fits in vehicle toolboxes, air-driven operation requires no external power.

Frequently Asked Questions

Q: What air compressor specifications are required?

A: Compatible with standard industrial air compressors meeting: 0.28-0.86MPa working pressure, ≥0.3m³/min displacement, and 1/4" NPT thread connection.

Q: Is the plastic reservoir strong enough?

A: Yes. The high-strength engineering plastic (PA6 + glass fiber) has 80MPa tensile strength and 100MPa compressive strength, with no deformation at 70MPa working pressure.
