The SILENT model represents Coltri’s excellence in soundproofing. It has been designed to meet the needs of those who use it intensively and requires large filling capacities. It is equipped with 4 front filling connections for high pressure hoses (from 232 to 420 bar), a control panel and electrical switchboard. The compressor is equipped with a three-phase electric motor and the most powerful pumping units. The design, which has been specially developed to improve soundproofing, allows the compressor to drop below the 70 dB threshold in service. To extend filter’s life, Tornado Refrigerator is optionally available. Various other options such as the electronic touch screen panel, Presec for filter saturationcontrol and the remote charging panel are also available.
