Page 15: Function Principle
Product identification Function principle With side-channel compressors, the impeller rotates contact-free in the compres- sor housing. The conveyed media is suctioned through the inlet (1) and accelerated spirally in the direction of rotation of the side channel. The conveyed media is accelerated by the centrifugal force in the radial blades in the direction of the side channel (2) inner wall, and from there is again supplied to the impeller (3). -

Page 18: Storage
Transportation and storage Storage NOTICE Mechanical damage and corrosion! Failure to adhere to the storage conditions can lead to mechanical damage and corrosion or can shorten the re-greasing interval. 1. Adhere to the storage conditions. 2. The maintenance intervals of the ball bearings (Maintenance [➙ 38]) become shorter as the time of storage increases. -
Page 19: Mounting
Mounting Mounting Measures after long-term storage Replace ball bearings and radial shaft seal When the length of storage until assembly is exceeded by 4 years for the storage conditions provided in Storage [➙ 18]. Replace the rolling bearing. Clean adjacent bearing areas for open ball bearings and re-grease. Replace and grease the radial shaft seal. -
Page 20: Set Up
Mounting Set up The G-BH8 must always be screwed to a fixed installation surface (e.g. floor) or a baseframe. Installation without spring elements is not permitted. The following assembly options are permitted: ▪ horizontally on the assembly foot (item 17, Structure [➙ 13]). ▪... -
Page 21: Fit Loose Silencer And Accessories
Mounting Fit loose silencer and accessories Fit loose silencer For G-BH8 with Y-pipe on the suction side (item 43), the silencer is enclosed separately due to technical packaging reasons and must be fitted by the op- erator. Remove transport protection. Position the silencer (item 3) on the Y-pipe with dowel pins (443) and secure using screws (444) and washers (479). - Page 22 Mounting WARNING Risk of burns due to temperatures of up to approx. 200 [392°F]! Contact with hot surfaces, pipes and hoses, can lead to burns. 1. Fit pipes and hoses with sufficient distance from highly inflammable materials (e.g. wood, plastic). 2.
