For years, air compressor enclosure has been provided in two basic structural types: either with the enclosure and not. Though the energy effectiveness and initial capacity performance features are the same between the two types of machine, there are several basic differences, some of which might impact long term performance. Duct sound attenuator.

For years, air compressor enclosure has been provided in two basic
structural types: either with the enclosure and not. Though the
energy effectiveness and initial capacity performance features are
the same between the two types of machine.

3. Duct sound attenuator
The roof and body panels of an enclosed compressor generally use
duct sound attenuator material in their construction, which is
conducive to a reduction in sound.

4. Acceptable noise level
The main drawback of an enclosed compressor for acceptable
noise level is simplicity of maintenance, as the door panels should
be removed or opened to work on the equipment. Nonetheless,
this disadvantage can be lessened with extra service features, like
optimal placement of filters and other serviceable components
