OP15 Bypass Oil Filter System

IPU’s OP15 bypass oil filter is a kidney loop filtration system that enhances engine lubrication beyond the capabilities of traditional oil filters.

OP15 bypass oil filter

The OP15 OilLife system uses both filtration and evaporation to remove solid, chemical and gaseous contaminants from oils and hydraulic fluids. When combined with IPU’s OilAlert oil condition sensors, you can extend oil life and enjoy the security of real-time reporting of oil quality.

The OP15 is suitable for up to a 300HP engine, and has an oil capacity of 30 litres on engines and 500 litres on hydraulics. The OP15 bypass oil filter has a 40 litres per hour flow rate.

It measures 27 x 32 x 19 (cm).


What industries can the OilLife OP15 bypass oil filter be used in?

The OP15 is essential for any industries that are extensively reliant on heavy equipment – especially if that equipment operates in remote locations. This includes, but is not restricted to:

  • Commercial and military shipping.
  • Passenger transport.
  • Haulage.
  • Landfill power generation.
  • Renewable power generation.

Oil filtration is especially important for equipment in some of the dirtiest commercial environments such as:

  • Open cast and underground mining vehicles.
  • Construction and earth-moving vehicles.
