PISTON COMPRESSORS

The Bottarini (member of Gardner Denver) piston compressors (Bultek, Siltek and Fortek) are adequate when the power requirements are limited to values between 1.1 kW and 7.5 kW, there are no powerful noise restrictions and their use is not continuous during the whole working day.

FIXED-SPEED ROTARY COMPRESSORS

The Bottarini fixed-speed rotary compressors are recommended when efficiency is required, where there are noise restrictions and the machinery must work continuously. These compressors generate compressed air by means of a rotary compressor equipped with stator made of helical profiles. These compressors are available with power of 2.2 kW to 250 kW, and flow of 0.2 to 40 m3/min.
