The noise level of the compressor is dramatically reduces by using the quiet box. It is also easy to transport due to the telescopic handle and wheels on the case.

Note – Your compressor hose will still attach to you compressor with a quick connect. The compressor hose will run out the top of the box, under the lid. Most compressors have the fitting running straight out of the compressor head and this can cause the hose to kink when you angle it towards the lid. We recommend you purchase an Angle Fitting to make the hose connection much easier by pointing the quick connect UP towards the lid. Angle fittings are available in 1/8″ and 1/4″.

The one you will need depends on your compressor setup. Please call us at 801.210.0479 if you are unsure and we will help you.
