The Tank Discharge Filter (TDF) is a simple yet effective hydraulic elevator oil filter system that removes
contaminants down to 5 microns. The TDF system mounts vertically on the valve/tank discharge line as
shown below (image bottom right). The filter bag is designed for easy replacement when dirty to maintain a
clean, well performing, hydraulic system (see TDF usage below).
The TDF system can be applied to all Maxton commercial elevator control valves (UC1/1A/2/2A and UC4/4M/
MR) as well as other commercial valves on the market using a 2 inch connection. When an elevator system
flow goes beyond 250 gpm multiple filters can be put together, accommodating more flow, using a manifold
arrangement. In this case make sure installation allows room for proper filter bag operation (expansion of
filter bag) with complete clearance.
TDF usage and maintenance recommendations:
Clean System Definition – This can be described as a completely new hydraulic elevator installation with new
oil. Maxton recommends checking the TDF quarterly to maintain optimal elevator performance. Filters need
replacing when white bag color turns brown/black to maintain a clean system.
Non-Clean System Definition – This is an elevator system in use without an oil filtration device. Maxton
recommends installing the TDF and running the pump (no coils energized) for several minutes to filter the oil
in the system. Note: If the TDF captures a substantial amount of contaminants (white bag turns brown/black
in color) during this process then Maxton recommends cleaning the tank, purging or replacing the oil and
replacing the TDF bag. Perform quarterly filter checks to maintain clean oil for optimal elevator performance.
