Key Features

● Innovative Dual-Power Hybrid System: Unique combination of 7.0HP gasoline engine and 4.0HP electric motor, 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.

● Heavy-Duty Cast-Iron Pump Head: High-strength cast-iron pump body with dual Dia.65mm pistons and long 58mm 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.120mm engine pulley + Dia.150mm motor pulley) with large 400mm aluminum flywheel, delivering stable high-torque output for both power sources.

● High-Flow Air Output: Consistent 425L/min air delivery regardless of power source, meeting the demands of multiple heavy-duty pneumatic tools operating simultaneously.

● Ultra-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.

●  Enhanced Portable Wheeled Design: Robust horizontal structure with heavy-duty rubber wheels, front swivel casters 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 aluminum flywheel cooling and integrated cooling fans for both 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 before each use; change pump oil every 500 working hours.

Clean air filter 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.

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.

Check belt tension and wear monthly; adjust tension or replace worn belts promptly.

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 system?

The dual-power design provides unmatched versatility. Use electric mode for quiet, cost-effective operation in workshops with power access; switch to gasoline mode for self-sufficient operation in remote construction sites, road repair locations and emergency situations where electricity is unavailable.

▼ What scenarios is this dual-power compressor suitable for?

Ideal for both indoor workshop use and outdoor field operations, including construction sites, road maintenance, mobile tire service, spray painting, pneumatic tool operation, and emergency rescue work. It is perfect for businesses that need compressed air both in fixed locations and on the go.

▼ Can I switch between power sources while the compressor is running?

No. Always turn off the current power source completely and allow the unit to come to a full stop before switching to the other power source to prevent damage to the transmission system.

▼ Why use an aluminum flywheel for this model?

Aluminum flywheel provides excellent heat dissipation, lighter weight and better dynamic balance, reducing starting load and vibration during operation, improving overall stability and service life for both power sources.

▼ What safety standards does the tank meet?

The 200L air tank is CE/ASME certified, complying with international pressure vessel safety standards for global market access.
