CLEANING
The downdraft table cleaning mechanism functions on
compressed air with a recommended supply pressure of 70-120
psi (5-8 bar). If required, mount a pressure reducing valve to
prevent overpressure.
The internal pressure regulator is factory set to ensure a working
pressure between the values of 65-70 psi (4.5-5 bar).
If the pressure is too high, the safety valve of the system will be
opened, thus decreasing the pressure until the system pressure
has reached an appropriate level.
1. Connect the downdraft table to compressed air. See Figure
A.9, item C. Connection is a 1/4 inch male industrial quick-
connect pneumatic nipple.
