Perkins filters

Types of Perkins filters

Perkins filters are an indispensable part of any diesel engine. They come in various types, each serving a particular purpose. Perkins oil filters clean and remove contaminants from engine oil. Consequently, they guarantee smooth engine operation and minimize wear and tear. Perkins oil filters can either be spin-on or cartridge-based.

• Spin-On Oil Filters

  Perkins spin-on oil filters have a metal housing that contains a filtering element inside. They are mounted on the engine using a threaded base. When changing the oil filter, the entire unit is removed and replaced with a new one. This makes maintenance of Perkins spin-on oil filters easy and quick.

• Cartridge-based oil filters

  Perkins cartridge-based oil filters are installed in a filter housing. They rely on external components for mounting. When replacing a cartridge-based oil filter, the filtering element is removed from the housing. The seal and the filtering element are then replaced in the housing. This type of oil filter uses fewer materials. As a result, they are more environmentally friendly.

Air filters are an essential part of any Perkins engine. Perkins air filters prevent dirt, dust, and debris from entering the engine's internal components. By doing this, they ensure smooth engine performance and longevity. Perkins air filters can either be dry or oil-wetted.

• Dry Air Filters

  Perkins dry air filters have filter media made of paper or non-woven fabric. They are designed to capture particles through a mechanical sieving process. Due to their design, dry air filters are less efficient in filtering fine particles from the air.

• Oil-wetted air filters

  Oil-wetted air filters come pre-treated with a thin layer of oil. The oil coats the filter media. It also acts as a sticky surface for airborne particles to cling onto. This enhances their ability to capture fine particles, making them more efficient than the dry air filter.

Perkins fuel filters are also an integral part of the fuel system. They serve one main purpose, which is to clean and remove contaminants and impurities from the fuel. By doing this, they protect the fuel injectors and ensure smooth engine performance. Perkins fuel filters can either be primary or secondary.

• Primary fuel filters

  Perkins primary fuel filters are located close to the fuel tank. Their main work is to remove large particles from the fuel before it enters the fuel system. They also trap visible contaminants, ensuring the fuel system's smooth operation.

• Secondary fuel filters

  Perkins secondary fuel filters are located further along the fuel line, close to the fuel injectors. They are responsible for filtering fine particles from the fuel. By doing this, they protect the fuel injectors from damage, ensuring the efficient delivery of fuel into the engine.

Some Perkins filters also come with a water separator. The water separator traps and removes any water present in the fuel. The water separator prevents engine misfires and corrosion, which can be caused by water in the fuel.

Perkins hydraulic filters are an important part of the hydraulic system. They ensure smooth and reliable operation of hydraulic circuits by filtering out particles and contaminants. This prevents wear and tear of hydraulic components such as pumps, valves, and actuators. As a result, hydraulic filters enhance the hydraulic system's efficiency and longevity. Perkins hydraulic filters are either suction line or pressure line filters.

• Suction Line Filters

  Perkins suction line filters are placed on the suction side of hydraulic circuits. Their main purpose is to prevent contaminants from entering the hydraulic system. They also protect components such as cylinders and accumulators from damage.

• Pressure line filters

  Perkins pressure line filters are placed on the pressure side of hydraulic circuits. They are responsible for filtering out particles and contaminants from the hydraulic fluid before it flows to actuators and working lines. Pressure line filters help maintain the desired pressure levels in the hydraulic system. They also ensure smooth and efficient operation of hydraulic circuits.
