At 65+ dB(A) it runs at roughly conversation level, so you can work with customers on site.

At 175 kg this is a fixed installation, plan its position before delivery. The airflow figure below is piston displacement, not usable output.

Dimensions (L x W x H) 1522 x 580 x 1242 mm Country of manufacture Italy Warranty 1 year Choosing the right option Choose this if noise is a genuine constraint and you need professional capability on single-phase power. Step down if noise is not an issue. The CPRC 3-100 has the same 3 HP motor at a fraction of the price, simply louder. Step up if you need two or more operators on air at once. The Ironman 5-150 delivers 17.9 CFM usable output, though it requires three-phase. Common questions Can I plug this into a normal power point?No. It requires a 15 Amp circuit, which uses a physically larger plug. This is the most common reason a compressor cannot be commissioned on delivery, so check first.How quiet is 65 dB(A) really?Roughly normal conversation level at four metres. A standard workshop compressor typically runs 10 to 15 dB higher, which is a substantial difference in perceived loudness.Will it run an interior cleaning gun continuously?Yes. These typically draw 5 to 7 CFM, and the 270 litre reserve provides a substantial buffer so the motor is not constantly cycling.Do I need a filter or dryer?For blow guns, a basic water separator is enough. For paint, coatings or PPF work, fit a proper filter and water separator. This applies to any oil-lubricated compressor.Can I move it myself?At 175 kg and over 1.5 metres long, no.
