Busch SAMOS SI 0045–0150 E1 is a side channel blower range.

Compare the manufacturer ratings below, then contact QCAS to establish the appropriate size, drive, installation and operating conditions for your application.

ISO 50 Hz manufacturer data. Negative differential vacuum converted to mbar absolute using 1013.25 mbar atmospheric reference. Range maxima may apply to different variants and are not simultaneous duty ratings.

Published values describe a product or range envelope. Maximum flow, pressure and vacuum may occur at different speeds, stages or configurations and must not be treated as one simultaneous operating point.
