SOUND LEVELS
of Paxton PX-Series Blowers with NEMA blowers measured with and without Polypropylene Enclosures
Paxton's industry-leading PX-series centrifugal blowers are designed for industrial manufacturing environments. As with all industrial machinery, the blower and its electric motor generate sound, with the sound level for the motor increasing with its horsepower and the sound level of the blower increasing based on the volume of air that it is moving.
|
Additionally, the configuration of the blower and its air delivery devices will impact sound levels, including the following factors:
- The type, material, and length of piping
- The type and size of air delivery devices
- The room height, size, and construction materials where the blower is located
- The motor brand and type
|
|
Sound levels can be mitigated through several methods:
- The use of a high-quality Paxton filter with silencer will reduce the sound levels by 3 dBA on average
- The use of a Paxton polypropylene blower enclosure, specifically designed to reduce noise levels, provide additional reductions of 9 dBA

The following table compares the sound levels for a Paxton Products blower equipped with a filter and silencer, then the same blower system with a polypropylene enclosure.
Typical sound levels, measured in a isolated production environment with uninsulated 4'' PVC Sch. 40 plastic pipe listed sound levels do not include air delivery devices.

As you can see, there is a significant sound reduction when a blower enclosure is used. The blower enclosure not only reduces sound levels by an average of 9 dBA (which, based on its log scale, is 10%), but also protects the blower from dust, dirt and washdown chemicals, thus extending the life of the blower and its filtration system.
