Why Choose a HPD Catch Can / Oil Separator?

HPD Catch cans are environentally friendly

Environmentally Safe 100% Compliant with Emissions Regulations

Read more

HPD diesel catch cans / oil air separators are one of the few on the market that do not vent harmful vapours into the atmosphere. This makes them fully compliant with all Australian emissions regulations and design rules in all states & territories.

Safe Crank Case Pressure

Read more

No expensive or time-consuming repairs from seals and gaskets failing due to excessive crank case pressures.

HPD catch can / oil air separators don’t develop excessive crank case pressure as our 8 layer stainless steel mesh filtration system does not clog up like paper or fabric cartridges of other systems. Our Catch Cans are not reliant on valves or bypasses that can commonly fail in real world applications.

Key Benefits:

  • Reduces oil in intake system
  • Allows intercooler to work efficiently
  • Eliminates carbon & oil build up in inlet manifold
  • Keeps inlet ports and valves clean
  • Reduces engine wear
  • Reduces exhaust smoke
  • Maintains economy
  • Keeps air and map sensors clean
  • Maintains engine performance

Kit features:

  • Billet Alluminum Catch can
  • Internal stainless mesh filters
  • Dipstick to check oil level
  • Simply unscrew base to empty oil
  • 16mm Screw in hose fittings
  • Mounting brackets & hoses

How Does a Catch Can Protect Your Engine?

HPD catch cans / oil air separators prevent oil from entering the intake manifold and mixing with the carbon from the EGR system, clogging up vital components and potentially causing damage (see blocked intake manifold in image A).

HPD direct-bolt on catch can / oil separator kits are ideal for 4WDs fitted with an intercooler or turbo kit and come complete with mounting brackets, rubber hoses and hose clamps. HPD catch cans significantly reduce oil vapour that can contaminate the intake system and therefore helps keep the intercooler clean (internally). This means your engine can receive optimum intake cooling, maintain efficiency and power delivery for longer.

Why fitting a HPD Catch Can is particularly important for modern Diesel vehicles?

Modern 4WDs tend to have more complex parts in the intake manifold such as sensors and EGR (exhaust gas recirculation) valves that can malfunction due to the film of oil produced by vapour from the crankcase breather system.

When the exhaust gas valve is commanded by the ECM (engine control module) to open and allow exhaust gasses back into the inlet sytem, these gasses contain small carbon particles (commonly known as soot) that fail to burn completely. These particles get deposited and stuck to surfaces coated with the film of oil and this process keeps repeating. Eventually, this process commonly causes intake manifold blockages, restricting air flow to the engine’s cylinders, resulting in reduced performance, black smoke, increased engine wear and even engine failure as shown in intake manifold in image A.
