Key Features

●  Innovative Dual-Power Dual-Pump System: Unique combination of 7.0HP gasoline engine, 5.0HP electric motor and two independent triple-piston pump heads, providing unmatched operational flexibility. Use electric mode for cost-effective, quiet operation where power is available; switch to gasoline mode for self-sufficient operation in remote off-grid locations.

●  Dual Independent Triple-Piston Cast-Iron Pump Heads: Two sets of high-strength triple-piston cast-iron pump bodies with large Dia.65mm pistons and 48mm stroke, wear-resistant and high-temperature resistant, built for long-hour continuous operation in all environments.

●  Professional Dual-Belt Drive Transmission: Separate precision-machined pulleys for engine and motor (Dia.80mm engine pulleys + Dia.100mm motor pulleys) with two 270mm iron flywheels, delivering stable high-torque output for both power sources.

●  High-Flow Dual-Pump Air Output: Consistent 525L/min air delivery regardless of power source, meeting the demands of multiple heavy-duty pneumatic tools operating simultaneously.

●  ltra-Large-Capacity 200L Pressure Vessel: Massive gas storage volume drastically reduces frequent start-stop cycles, extends continuous working time, reduces engine/motor wear and improves overall operational efficiency.

●  hanced Portable Wheeled Design: Robust horizontal structure with heavy-duty rubber wheels and ergonomic handle, providing exceptional maneuverability across all terrains and work sites.

●  CE/ASME Certified Safety: 200L heavy-duty pressure vessel meets international safety standards for global sales and use in various industrial and outdoor applications.

●   High-Efficiency Cooling System: Large-area fin-type heat dissipation structures for both pump heads and integrated cooling fans for engine and motor ensure exceptional heat dissipation during continuous full-load operation.

●   User-Friendly Dual-Mode Operation: Simple power source selection switch, clear pressure gauge and convenient drain valve for easy operation and maintenance in all conditions.

Expert Advice

General Maintenance

Check pump lubricating oil level for both units before each use; change pump oil every 500 working hours.

Clean air filters weekly; inspect and clean cooling fins monthly.

Drain condensed water from the tank bottom valve after each use; drain every 2 hours under continuous heavy-duty operation.

Check belt tension and wear for both pump sets monthly; adjust tension or replace worn belts promptly.

Gasoline Engine Mode Specific

Check engine oil level before each use; change engine oil every 50 working hours.

Use clean unleaded gasoline with octane rating 92 or higher; never operate with less than 1/4 tank of fuel.

Use in well-ventilated outdoor areas only; never operate in enclosed spaces to prevent carbon monoxide poisoning.

Allow a 10-minute cooling break after every 30 minutes of continuous full-load operation.

Electric Motor Mode Specific

Ensure stable 220-240V single-phase power supply with standard-gauge power cables.

Check electrical connections and insulation regularly for safety.

Do not overload the circuit; use a dedicated circuit for the compressor.

Allow a 10-minute cooling break after every 40 minutes of continuous full-load operation.

Common Guidelines

Factory preset working pressure is 8Bar; do not adjust pressure regulator beyond factory settings.

Depressurize the tank below 1Bar before moving or performing maintenance.

For long-term storage: Drain all fuel from the engine, change engine and pump oils, depressurize the tank completely, and store in a dry, well-ventilated area away from ignition sources.

Troubleshooting Guide

FAQs

▼ What are the main advantages of the dual-power dual-pump system?

The dual-power design provides unmatched versatility, allowing operation both in workshops with power access and in remote off-grid locations. The dual-pump configuration delivers higher airflow and provides redundancy - if one pump fails, the other can still operate, minimizing downtime.

▼ What scenarios is this 300L tank version suitable for?

Ideal for large-scale outdoor construction projects, long-duration road repair work, big industrial workshops, heavy-duty mobile tire service, large-area industrial spray painting, multiple simultaneous pneumatic tool operation on remote job sites, and extended emergency rescue operations.

▼ What is the benefit of the 300L large-capacity tank compared to smaller tanks?

The 300L tank provides significantly longer continuous working time between compressor cycles, reducing frequent engine/motor start-stop operations. This not only extends the service life of the power units but also improves overall work efficiency, especially for applications requiring sustained high airflow.

▼ Can I run both pumps simultaneously on the same power source?

Yes. Both pumps can be operated simultaneously on either the gasoline engine or the electric motor, delivering maximum airflow of 525L/min. You can also run only one pump for lower-demand applications to save fuel or electricity.

▼ What safety standards does the tank meet?

The 300L air tank is CE/ASME certified, complying with international pressure vessel safety standards for global market access.
