Key Features

●  Quad-Motor Low-Speed Silent System: Four independent low-speed pumps running at only 1450/1750 RPM, 8-piston structure providing massive-volume airflow while maintaining ultra-low noise, suitable for noise-sensitive large-scale 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 industrial applications.

●  Built-In Redundancy & Load Adaptability: Can run with one, two, three or all four motors, allowing continuous operation even if one or two units fail, reducing downtime for continuous-production scenarios.

●  Portable Wheeled Horizontal Design: Equipped with heavy-duty rubber wheels and an ergonomic handle, easy to move between large-area workspaces and industrial zones.

●  8-Piston Stable Pump Structure: Each pump adopts dual φ63.7mm pistons with 12mm stroke, total 8 pistons ensuring ultra-smooth 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: 150L 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 all four 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 (528L/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 quad-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 quad-motor silent design bring?

It provides three core benefits: massive-volume total air output, ultra-low noise thanks to low-speed pumps, and quad-unit redundancy to keep working even if one or two motors malfunction.

▼ What scenarios is this compressor suitable for?

Ideal for multi-station dental hospitals, large beauty centers, professional art airbrushing, heavy-duty painting, multiple simultaneous large-size pneumatic tools, and light-industrial environments requiring clean, quiet high-flow compressed air.

▼ How does power frequency affect performance?

At 50Hz, total air delivery is 440L/min; at 60Hz, pump speed rises, boosting total airflow to 528L/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 150L air tank is CE/ASME certified, complying with international pressure vessel standards for global market access.
