Do I need an enclosure?

Posted on January 3rd, 2018

Very rarely and generally only if you use air lines, for example to clean down tools.
To give a sense of proportion, 90% plus of AirBenches do not have an enclosure. They are designed to work efficiently without them.
Enclosures can usually be retrofitted without too much trouble if you change the application of your AirBench.
