GESTRA steam traps UNA 14, UNA 16, UNA 16 A do not require any special maintenance. However,
if used in new installations which have not been rinsed it may be necessary to check and clean the
trap.
The GESTRA air trap UNA 14 P does not require any special maintenance. If, however, the trap is
used with very oily condensate we recommend to clean the trap at regular intervals or to install an
oil separator upstream of the trap.
