Low-Viscosity Filter Cart

Low-Viscosity Filter Cart

The Low-Viscosity Portable Filter Cart System provides convenient off-line filtration, flushing, conditioning, and fluid transfer of industrial oils. The system is capable of delivering a flow up to 7.25 GPM and is rated for use with lubricants up to a viscosity 2,500 SUS @ 100ºF. To ensure equipment receives the cleanest oil possible for increased life, the system utilizes a two-stage filtration process–oil enters through the primary element (10 micron absolute Beta > 200) where coarse particulate is removed and then moves through the secondary filter element (3 micron absolute Beta > 200) where fine particulate  is removed. For added utility, the new filtration system features differential pressure gauges that indicate when each of the filter elements need to be changed. Two sampling ports are included for safely sampling and monitoring the condition of oil.

The systems are available with 10 foot heavy-duty hydraulic hoses with quick connects or 6 foot heavy-duty hydraulic hoses with 3 foot wands.

A variety of filter media elements are available to meet recommended manufacturer cleanliness levels.


  • Bypass Valve – Allows transfer of oil without filtering
  • Oil Sampling Ports – Two sampling ports available to monitor condition of oil
  • Dual Filters – Two-stage filtration for long element life and pump protection
  • Industrial Strength Tires – Wide tires capable of getting over large grate gaps
  • Heavy Duty Cart – Rugged and built to last
  • Check Valve – Prevents fluid back flow when pump vertically
  • Differential Pressure Gauges – Indicates when elements need to be changed
  • Hose & Wand Assembly – Six foot heavy-duty hydraulic hoses with 3′ long metal wands
  • Quick Connects – Ten foot heavy-duty hydraulic hoses with quick connects
