Note: A trap should be selected for the most appropriate working pressure differential and not on the basis of load, e.g. 80 kg / h at 7 bar
differential should be handled with the SIB30/7 and not the SIB30/4.

For full details see the Installation and Maintenance Instructions
(IM-P110-05) supplied with the product.
Installation note:
Install in a horizontal pipe, below the drain point. If installed in
exposed positions, consideration should be given to insulating
the trap.
Example: 1 off Spirax Sarco 1⁄2" screwed BSP SIB30/6 sealed
inverted bucket steam trap.
Note: The cover (and flanges when specified) are welded to the
body using the TIG process. Welds are approved in accordance
with ASME section IX and BS EN 288.
