Why You Should Replace Filters On Time

The performance of your vehicles, and indeed your operators, is enhanced by regular filter replacement. As a relatively low-cost item, the effects, both short and long term, and the resulting costs far outweighs the expenditure. 

Filters catch impurities, in various forms, and enable a consistent flow of clean air or liquid to ensure that vehicles operate as the manufacturer intended. Dirty and clogged filters reduce performance, increase fuel consumption, can potentially cause internal damage, and increase emissions. 

Poor filtration can also have a significant impact on the ECU of a vehicle (electronic control unit) again causing it to operate much less efficiently plus reducing durability and reliability. The solution is to change filters when required and recommended by the manufacturer. 

Construction and similar sites, by their nature, are very dusty and dirty places. The contaminants and impurities can be sucked into the vehicle systems, whether engine, hydraulic or the cabin.  Filters are the first line of defence in ensuring that the dust and dirt particles are stopped and prevented from contaminating and damaging the internal working mechanisms. 

It is generally widely known that the replacement of air and oil filters on a vehicle’s engine is essential. Fuel filters are another important item to replace regularly as they prevent any impurities in the diesel or petrol from entering the cylinder head, the important part of the engine where combustion occurs. Clean fuel will ensure clean running and so improved economy and reduced emissions. 

Keeping filters clean ensure that operating pressures are maintained, including in hydraulic systems. Again, less energy is then required to operate the plant equipment so contributing to efficiency and economy. 

Equally important is the health of the plant or vehicle operator. Construction and similar sites are dusty places to work, protecting the operative, particularly with the onset of more and more respiratory diseases and viruses is highly important.  Indeed, it can also protect against future health issues and associated litigation. 

Ultimately, replacing filters on time, and keeping a visual check, where possible, in between service intervals, ensuring that the filter is clean and not of a dirty colour, which indicates reduced flow, will ensure that there is less opportunity for malfunction, failure and the resulting downtime whilst the vehicle is repaired and returned to service. 

Maintaining and adhering to the vehicle’s maintenance schedule is essential. Especially if a vehicle is working on site regular filter changes are even more important. As mentioned previously, filters are a relatively low-cost item but the protection they provide, and the prevention of future problems and costs is a small price to pay. 

It is also important to use quality filters, designed and produced to the manufacturer’s specification, to ensure that a vehicle’s systems operate efficiently. Holm Filters are often produced in the same factory as those of the OEM (original equipment manufacturer) products and so share the same qualities.
