Porter Cable CMB15 150 PSI 1.5 Gallon Oil-Free Fully Shrouded Compressor Review

I’ve owned this dainty, easily portable, and well-shrouded unit for over two years now and have been using it weekly to air up my tires, cleaning vacuum filters and my garage workbench, and run a brad nail-gun. I love that I keep finding more uses for it. This little powerhouse unit is ‘[easyazon_link asin=”B006CVXGR0″ locale=”US” new_window=”default” nofollow=”default” tag=”airtoolguy0a-20″ add_to_cart=”default” cloaking=”default” localization=”default” popups=”default”]Porter Cable CMB15 150 PSI 1.5 Gallon Oil-Free Fully Shrouded Compressor[/easyazon_link].

I would say, overall it is fabulous with light to medium-duty projects (good for home use and can even cover some industrial jobs), convenient to carry around the house and shop, and not too noisy to disturb angry neighbors. The unit charges pretty fast from zero to its maximum 150PSI, and it’s convenient that you can tailor set the pressure to use (output pressure can be set independent from tank pressure). I had to purchase another hose and some attachments, which I find more efficient with the main compressor, but other than that I cannot ask for more – this is my favorite handy tool!

Ideal lightweight powerhouse

The Porter Cable CMB15 (20 pounds) has no problem keeping up for longer periods such as for use with a brad nailer, and inflation tasks, as there is enough pressure for these jobs. With a 1.5 gallon tank capacity, it offers a competitive functional performance. Even more, because of its 2.0 SCFM @ 90 PSI feature, the unit recovers after a short period, and can accordingly keep up with relatively high requirement usage.

Highly portable and protected

This compact light appliance, can be toted with ease from your home to job site, and vice-versa (saving you from unwanted body strains as with large machines). Its small size makes this compressor ideal to maneuver, even when working in small rooms. The design has been built with full enclosure to provide optimal protection to its parts, avoid damage, and generally make it safer for everybody during usage
