Pneumatic tools require air compressors to function properly. The obvious drawback linked with air compressors is that they can be rather bulky and heavy. Pneumatic tools are just as compact as similarly functioning power tools. However, adding huge air compressors and lengthy hoses into the equation makes pneumatic tools much less portable.
Pneumatic tools are generally quite expensive. It is recommended that consumers purchase abrasion-resistant flexible hoses for their pneumatic tools. These hoses however, are linked with high price tags further driving up the costs associated with pneumatic tools.
Pneumatic tools require a considerable amount of maintenance to keep in proper working order according to the sources at Canada's Centre for Occupational Health and Safety. It is recommended that the oil in pneumatic tools get changed every six months or so to keep the tool properly functioning.
Power tools and pneumatic tools are going to make a lot of noise while in use. The air compressor feature of pneumatic tools also makes a lot of noise, which makes operating pneumatic tools a louder process than operating power tools.
Monster Guide claims that pneumatic tools can spit oil while in use. Another disadvantage with air tools is that the excess air that gets trapped in them must be blown out before using the tools. Not blowing out any air left in the tool can lead to performance problems and safety risks according to Ask The Builder.
