Tank bottoms are normally sloped approximately half an inch per foot of tank diameter from the high side to the low side. They are used for non pressure /non vacuum applications and can be equipped for complete drainage with internally flush center drains. The insulation between the two tank bottoms is of cylindrical perlite. They are cleaned periodically by circulating accumulated method. All tank inlet and outlet connections, mixing devices and water draw-off connections are located beneath the level of the tank bottom. The tank-cleaning process can reduce hazardous waste generated from tank bottoms.

Tank breather adapter is a simple adapter. It can turn spin-on filter elements into great big tank breathers. It provides better filtration of air entering larger hydraulic tanks, plus much longer filter life. These adapters have straight-threads on one end to attach to the filter element, and NPT threads on the other end to go into a half-coupling welded to the tank top.

Breather Tank is used to vent a dry sump tank, rear end, or any other application where a breather catch tank is required. It comprises a closed reservoir above the container but having a conduit which depends into the container and has an opening which determines liquid level in the container.
