The powerful Makita MAC5200 oil-based compressor is uniquely housed within its own dolly making it easily portable. The dolly handle is situated high enough to suit taller individuals who don't have to bend down to reach it as with some other compressor designs. Conveniently, it can also be folded down to make the whole unit more compact and can even store a long air hose. For any other air compressor accessories, there is a good-sized storage compartment on the top of the main compressor body. The relatively powerful 3hp motor requires a dedicated electrical circuit if you want to prevent circuit breakers from flipping - preferably rated for 20A, not an impossible feat in most households. The unit also ships with the more desirable ball drain valve to remove excess condensation from the air tank. Earlier versions of the compressor shipped with sub-standard wheels and wheel assemblies, but Makita has listened to complaints and has since upgarded them to improved pneumatic ones making it easy to transport the compressor unit longer distances. Although the unit is able to deliver a relatively large air volume, it still only has a duty cycle of 50% like most portable compressors.
