Typical technical specifications for 1680 Watt compressors: Total motor power: Starts from 1680 Watts for a single motor, and in some large models (like 90 or 100-liter tanks) reaches a multi-motor system (e.g., 1680 Watts x 2 or x 3) to generate huge total power and superior filling speed. Airflow rate: Fast and powerful pumping ranging from 150 to 300 liters per minute (depending on the number of motors and tank size), ensuring efficient and uninterrupted operation of pneumatic tools. Working pressure: Usually reaches 8 bar (equivalent to about 115 PSI), which is the ideal standard pressure for most spray guns, blowers, and nail guns. Rated speed: Motors rotate at a speed of up to 2850 RPM to ensure superior air pressure and flow rate. Key advantages of the oil-free compressor: 100% clean air: Ideal for car painting and spray painting (to avoid oil spots), in dental labs, and for precise operation of smart devices. Virtually maintenance-free: Does not require checking or periodic changing of oil level, saving long-term operating costs. Environmentally friendly and quiet: This design features a very low noise level (silencer), making it comfortable for use indoors and in workshops near residential areas. Advanced protection systems: Equipped with automatic protection against overheating and overcurrent to ensure a long lifespan for the motor.
