Parker-Watts SA605MD Internal Automatic Float Drain, Brass, 175 PSI, QUBE F71 F75 B75
The Parker-Watts SA605MD is the brass internal automatic drain for the QUBE series of filters and filter/regulators. It threads into the bottom of the bowl in place of the manual drain cock and empties collected condensate by itself, float operated, with no power and no timer to set.

Installation notes
The host filter has to be mounted vertically in the pipe line for a float drain to work correctly. If the ambient temperature can fall below freezing, the air passing through must already be dry, because a drain with standing water in it will freeze and stop cycling. The drain is hand tightened into the bowl, no tools required.
Why brass
The brass bodied SA605MD is the option to specify where the plastic drain has had a hard life: hot compressor rooms, oil carryover, wash-down areas and any station that gets bumped. It is a special option part rather than a stocked catalog line, so lead times from Parker can run several weeks. Worth keeping one on the shelf if you run a bank of QUBE filters.
