Blow-Off Module

Pneumatic Blow-off module provides 25cc of stored compressed air to give a robust pulse to dissipate vacuum in a system whenever the vacuum pump air supply is vented. All connections to the vacuum pump are internal for a very compact, foolproof, and neat installation.

A single 3-way normally-closed air supply valve can be used to control the pump and blow-off functions. When the 3-way valve supplies air to the pump, the blow-off reservoir is charged. When the 3-way valve shuts off and exhausts the pump air supply, the stored reservoir air will automatically discharge directly into the pump vacuum chamber to dissipate system vacuum.

How to Order: Add suffix “-BO” to a Chip pump assembly number. Not available on H, Z, and VCR bases.
