Rotary screw air compressors work by trapping air between two meshed rotors and reducing the volume of that trapped air as it moves down through the rotors. This decrease in volume results in compressed air, which can be used to power pneumatic air tools, inflate tires and perform many other applications. .
Stellar Truck Mounted Rotary Screw Air Compressors boast many hardworking, long-wearing features: 1. Precision-engineered, rotary screw air-end is oil-injected to eliminate metal-to-metal contact of the two compressor screw lobes for continuous 100%. .
The advantages of rotary screw mobile air compressors over other types of compressors that can be mounted on service vehicles include: 1. Continuous airflow/100% duty.
