Understanding Air Compressor Noise Levels
Air compressor noise levels depend on motor type, compressor design, and installation environment. Reciprocating compressors produce sound levels between 70 and 95 dB(A), while rotary screw models generally operate at 60 to 75 dB(A) due to enclosed housing and precision engineering. Oil-free compressors, common in Perth’s food processing plants, often emit louder noise profiles than lubricated models because of metal-to-metal contact.
Sound-dampening enclosures, vibration isolation, and intake mufflers reduce airborne and structure-borne sound. Compressor Systems technicians in Perth fit compressors with tailored insulation and install equipment away from high-traffic workspaces to control decibel exposure for mining or automotive manufacturing personnel.
Table: Typical Air Compressor Noise Levels by Type
| Compressor Type | Mean Noise Level (dB[A]) |
|---|---|
| Reciprocating Piston | 70–95 |
| Rotary Screw | 60–75 |
| Oil-Free Scroll | 65–80 |
Employers in Western Australia adhere to WorkSafe regulations, limiting prolonged exposure to noise above 85 dB(A) within enclosed industrial sites. Quiet compressors—selected according to application and building layout—help optimise comfort and safety for compressor operators and maintenance crews.
Are There Quiet Air Compressors?
