Key Features

● Dual-Motor Low-Speed Silent System: Two independent low-speed pumps running at only 1450/1750 RPM, 4-piston structure delivering high-volume airflow while maintaining ultra-low noise, suitable for noise-sensitive 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 precision applications.

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

● Portable Wheeled Horizontal Design: Equipped with heavy-duty rubber wheels and an ergonomic handle, easy to move between workstations or rooms.

● 4-Piston Stable Pump Structure: Each pump adopts dual φ63.7mm pistons with extended 15mm stroke, ensuring higher displacement, steady airflow and long-term durability.

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

● CE/ASME Certified Safety: 50L horizontal 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 (332L/min) under 60Hz power; ensure stable 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 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 silent design bring?

It provides three core benefits: higher-volume air output thanks to extended-stroke pistons, ultra-low noise thanks to low-speed pumps, and redundancy to keep working even if one motor malfunctions.

▼ What scenarios is this compressor suitable for?

Ideal for dental clinics, beauty salons, art airbrushing, small-scale painting, multiple small pneumatic tools, and professional indoor environments requiring clean, quiet high-flow compressed air.

▼ How does power frequency affect performance?

At 50Hz, total air delivery is 276L/min; at 60Hz, pump speed rises, boosting total airflow to 332L/min for faster 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 50L air tank is CE/ASME certified, complying with international pressure vessel standards for global market access.
