Buying Guide For Westward 20 Gallon Air Compressors
Tank Size and Pressure Capacity
The 20 gallon tank size provides an excellent balance between airflow capacity and portability. Consider compressors with a maximum PSI of at least 150 for versatile usage, as higher PSI offers the ability to run a wider range of pneumatic tools.
CFM and Recovery Rate
Cubic feet per minute (CFM) indicates the compressor’s air delivery rate—higher CFM means quicker recovery and the ability to sustain continuous tool operation. Look for models offering 4+ CFM at 90 PSI for standard applications, with higher values preferred for intensive tasks.
Power Source and Motor Type
Electric compressors with 115V or 230V motors are convenient for indoor and garage use, while gas-powered models provide mobility and high power for outdoor applications. Oil-free pumps reduce maintenance but may have shorter lifespans compared to oil-lubricated units, which require regular servicing.
Noise Level
Noise is a vital consideration for indoor or residential use. Compressors featuring noise levels below 70 decibels are considered ultra-quiet, suitable for noise-sensitive environments such as workshops and garages.
Maintenance and Durability
Oil-free compressors minimize upkeep but check for features like automatic drain valves and thermal overload protection to safeguard the compressor. Durable materials such as stainless steel tanks and rubber feet improve longevity and reduce vibration.
Portability Features
Wheels, handles, and compact designs improve mobility, making it easier to transport the air compressor around job sites or workshop areas. Consider your workspace and portability needs when selecting a model.
