Key Features

● Dual-Motor High-Power Low-Speed Silent System: Two independent low-speed high-power pumps running at only 1450/1750 RPM, 4-piston large-displacement structure delivering strong large-volume airflow while maintaining ultra-low noise, suitable for noise-sensitive heavy-duty professional environments.

● Maintenance-Free Oil-Free Operation: No pump oil required, eliminates oil contamination risk, outputs clean dry compressed air ideal for hygiene-critical and high-precision industrial applications.

● Built-In Redundancy & Load Adaptability: Can run with one or both motors, allowing continuous operation even if one unit fails, reducing downtime for heavy-duty continuous-use scenarios.

● Vertical Space-Saving Wheeled Design: Unique vertical compact structure saves floor space, equipped with heavy-duty rubber wheels and protective handle, easy to move between workstations.

● 4-Piston Large-Size Stable Pump Structure: Each pump adopts dual φ70mm large-size pistons with long 22mm stroke, total 4 pistons ensuring ultra-smooth high-displacement airflow and long-term heavy-duty durability.

● Dual-Frequency Compatibility: Optimized for both 50Hz and 60Hz power grids, compliant with global regional power standards.

● CE/ASME Certified Safety: 115L vertical air tank meets international pressure vessel safety standards for worldwide sales and use.

● Precision Pressure Control: Dual pressure gauges with integrated filter-regulator unit for accurate pressure adjustment and air purification.

Expert Advice

● Daily Maintenance: No oil changes required. Clean both air intake filters regularly to keep airflow stable and noise low.

● Pressure Operation: Factory-set maximum working pressure is 8Bar (116PSI). Do not modify the pressure switch beyond factory settings.

● Operating Environment: Use in well-ventilated indoor areas; avoid high-temperature, dusty or damp surroundings to protect low-speed silent pumps.

● Frequency-Specific Performance: Higher total air delivery (590L/min) under 60Hz power; ensure stable high-power power supply to prevent motor overload.

● Condensate Drainage: Drain condensed water from the tank bottom valve after each use; drain every 4 hours under continuous heavy-duty operation to avoid internal corrosion.

● Duty Cycle & Cooling: Allow a 10-minute cooling break after every 20 minutes of continuous dual-motor operation to extend motor life.

● Mobility Safety: Depressurize the tank below 1Bar before moving, and move slowly using the wheeled base and handle.

● Storage Guidelines: Depressurize the tank, drain all moisture, and store in a dry, dust-free indoor space.

Troubleshooting Guide

FAQs

▼ What advantages does the dual-motor high-power vertical silent design bring?

It provides three core benefits: high-power large-displacement air output thanks to large-size pistons and long stroke, ultra-low noise thanks to low-speed pumps, dual-unit redundancy, and vertical compact structure saving valuable workspace.

▼ What scenarios is this compressor suitable for?

Ideal for heavy-duty beauty salons, large-scale art airbrushing, multi-tool painting workshops, small industrial stations, and professional environments requiring space-saving clean, quiet high-power compressed air.

▼ How does power frequency affect performance?

At 50Hz, total air delivery is 490L/min; at 60Hz, pump speed rises, boosting total airflow to 590L/min for faster heavy-duty working efficiency.

▼ Is oil-free operation truly maintenance-free?

Yes. No oil refills or oil changes are needed; only regular intake filter cleaning is required, greatly reducing maintenance costs.

▼ What safety standards does the tank meet?

The 115L vertical air tank is CE/ASME certified, complying with international pressure vessel standards for global market access.
