Non-contact, non-wearing labyrinth seals prevent bearing lubricant entering the compression chamber. The design also features heavy duty, low friction ball and roller bearings and helical drive and timing gears. Thrust balance pistons equalise the loads across the bearings, allowing each bearing to achieve its optimum life expectancy.
Free air delivery at stated working pressure and measured and tested in accordance with ISO 1217 Ed. 4 Annex C (fixed speed) & E (variable speed), at the following reference conditions:
- Air intake pressure – 1 bar a
- Air intake temperature – 20ºC
