3 POWER CLAMPING www.jergensinc.com 3.44 Jergens, Inc. • Jergens Way • 15700 S. Waterloo Road • Cleveland, Ohio 44110-3898 USA Pre-Fill Boosters • Self Bleeding • Easy View Reservoir • 15:1, 30:1, and 54:1 Boost Ratios These units offer many more advantages than conventional boosters, while maintaining the same basic simplicity. The pre-fill booster has two automatic cycles. The first cycle pre-fills the work circuit using low pressure with a large reservoir to provide volume. The second cycle then automatically provides high pressure, as needed. These units also provide automatic bleeding of the work circuit. This self-bleeding feature negates the need to “bleed the lines” after it is set up. The pre-fill booster is ideal for any general use production system requiring maximum efficiency with minimum effort! Pre-fill boosters must be used in the upright (vertical) position. • Installation Kits Available. See Page 3.48. • See page 3.45 for Rapid Exhaust and Rapid Advance Kits, Handles, and Mounting Bases.
