How Portable Compressors Work

The majority of portable compressors — including those manufactured by Quincy — feature a single-stage, reciprocating/piston design. Piston compressors work by forcing air through an inlet valve into a cylinder, where the reciprocating motion of a piston compresses it. Once it compresses the air to the desired level, it activates a discharge valve, sending it out to power a tool or whatever attachment to which the unit will be connected.

Single-stage compressors feature a single valve and piston assembly. This makes them smaller, lighter and more portable, but limits the amount of power the unit can provide. For this reason, they are most commonly used in garages, workshops, construction sites and other applications where you can sacrifice continuous power for the sake of value or portability.
