Oil-free series: Quiet and low vibration

Each of the new BOGE scroll compressors in the series operates with two spirals – one of which is fixed while the other rotates eccentrically – which intertwine without touching and therefore do not require oil lubricant. Intake air is continuously compressed into an increasingly narrow interior space, which quietly produces high quality compressed air that is oil-free with minimal vibration.

The EO 22 D with integrated refrigeration dryer and focus control 2.0, for example, delivers oil-free compressed air at 8 bar and delivers 2520L/min at a sound level of 64dB, which is 5dB lower than a silenced BOGE screw compressor.

The EO series is designed to match compressed air output with demand to enable improved energy efficiency. Where higher quantities of compressed air are required, up to four compressors can be accommodated in a single housing.

Mark Whitmore, general manager at BOGE Compressors, comments: “The noise emitted by many air compressors is such that normally they must be housed a fair distance away from work areas. The new EO series, however, is so quiet and pulsation-free that it can be installed in close proximity to people and work stations. Additionally, because it is absolutely oil-free, it is fit for use in sensitive and clean environments.”
