Note: All dimensions are in metres unless stated otherwise.
The maximum pipe run figures are based on using copper pipe with an inside diameter
of 2mm less than the Ø.
The table and illustration above is a guide only and does not in any way override the de-aerators
manufacturers instructions.
A top feed oil tank fitted with a de-aerator using
an internal non-return valve should have any non-
return valve/s fitted in the base of the tank to the
suction line removed to assist purging air from the
oil line.
A capillary type valve provides a neat and simple
installation. Alternatively, a fusible link or electrical
system may be used.
