Air Compressors

Air compressors and air line components: vertical and portable compressors, modular filter-regulator-lubricator units, particulate filters, desiccant dryers, regulators with gauges, air chucks, couplers and plugs, and hose ends.

Couplers come in incompatible profiles — industrial (I/M), automotive and ARO plugs will not cross-connect, so standardize on one across the shop. Moisture is what kills air tools, which is what the filter and dryer are there for.
