Product Details
The California Air Tools 20040DC Ultra Quiet and Oil-Free Air Compressor is engineered to be one of the quietest 4.0 horsepower air compressors available, producing only 75 decibels of sound. It features two 2.0 HP motors that operate at 1680 RPM, ensuring reduced noise, vibration, and wear. The oil-free dual piston pump system is designed for longevity, high performance, and durability, with SP-90407 motor/pumps tested for a pump life of at least 3000 hours before service, providing 30% more life before repair. The unit includes a large 20.0-gallon steel air tank suitable for various locations. It incorporates air dryers specifically designed to remove water vapor from the compressed air, protecting sensitive tools and machinery. An after cooler serves as a heat exchanger that cools the discharge air and condenses water vapor into liquid form before it enters the air dryer. This air compressor is particularly well-suited for indoor environments such as offices, shops, stores, warehouses, or homes, where noise reduction is essential. It offers a combination of power, airflow, and reliability with a significant reduction in noise levels.
