Flow Rates: Flow Rates Range from 1 GPM to 5 GPM

Precision Filtration Products’ Drum Top Filter Unit sit securely on top a 55 gallon drum. It is constructed with a strong, powder-coated steel, all welded frame. (Need a unit with a lighter frame? This unit is also available with an aluminum frame!) Our DTF Filter Unit is the ideal filtration system for recirculating or transferring fluids in and out of a 55 gallon drum.

The DTF Filter Unit is ideal for high viscosity lubrication and hydraulic oils. It can be used for filtering new fluids during transfer and replenishment, as well as filtering fluids currently in service. The two stage filtration offers the advantage of removing both particulate and water contamination.

The DTF Filter Unit includes sampling ports on the inlet and outlet connections to provide ISO Code comparisons. This will allow you to meet your target ISO Cleanliness Codes and prolong the life of your equipment and fluids. Saving you time and money.

*Manufacturer’s maximum recommended viscosity is 25,000 SSU. Calculations above are based on filtering ISO 320 @ 1 GPM at desired PSID. Effective filter sizing requires consideration of flow rate, viscosity (operating and cold start), fluid type, and degree of filtration. When properly sized, by-pass during cold start can be avoided/minimized and optimum element efficiency and life achieved.
