High-Viscosity Hand-Held System

High-Viscosity Hand-Held System

In the past choices were very limited when it came to filtering lubricants with viscosities greater than 500 SUS @ 100ºF. The problem with attempting to filter a high viscosity oil with a lower viscosity system is that the pump and filters are not designed to work with higher pressures required to push high viscosity fluids through the system. As a result these low viscosity units operate primarily in “bypass” mode where little if any of the high-viscosity oil gets filtered.

That is where Trico’s High-Viscosity Hand-Held System comes in. This system is specifically designed for high-viscosity fluids associated mainly with gear oils and can filter oils up to 7,500 SUS @ 100ºF (1600 cSt @ 40ºC).

To ensure that the equipment receives the cleanest oil possible, for increased equipment life, Trico’s High-Viscosity Hand-Held Filtration System provides two-stage filtration. The oil flows through the primary filter first, where coarse particulate is removed. Then the fluid flows through the secondary filter where fine particulate and water are removed.

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


  • Differential Pressure Gauges – Indicates when elements need to be changed
  • Oil Sampling Ports – Two sampling ports available to monitor condition of oil
  • Dual Filters – Two-stage filtration for long element life and pump protection
  • Compact – Lightweight design provides flexibility to service equipment located in hard to reach areas
  • Hoses – Heavy-duty hydraulic hose
