Air inhaled by vehicles’ motors contains dust particles, pollutant agents and humidity. Therefore, it is essential to protect the motor from all kinds of impurities.

The most important component of Millard air filters is paper, which is especially designed to stop dust filtering through and to protect against humidity. The quality of Millard Global air-filtering paper is excellent, as well as its treatment with impregnations which provide enhanced dust retention and resistance to humidity. In addition, totally symmetric folds allow stable admission in all kinds of environments. If a paper filter did not have these features, it could break allowing the passage of particles and even paper, and this would cause motor damage.

To obtain better motor performance and better protection of its mobile parts, the air filter should be changed regularly, as is indicated in the vehicle's operating instructions.

Millard oil filters avoid motor wear and tear, as well as guaranteeing an optimum oil state. The purpose of an oil filter is to protect motor lubricating oil from dirt (dust, oil coal, soot) which causes premature bearing wear and tear.

Oil filters have a safety valve inside. In the case paper is saturated, this valve opens thanks to the pressure of an oil pump, allowing the passage of non-filtered oil and thus avoiding motor operation without lubricant. Nevertheless, depending on the vehicle's manufacturer, some filters do not require this valve.

The anti-drain valve allows an oil reserve to be maintained when the motor is switched off. This avoids damage to the motor when it is switched on when cold, as the upper parts need longer to be lubricated and this only happens when the filter is completely full of oil.

There are two types of oil filters: sealed filters and element-type filters. The former protect the filtering surface with a specially-designed metal case, which has the valves which were mentioned above. Element-type filters do not need this case as it is the motor itself which provides this. When this type of filter has no metal parts it is called “eco-friendly filter" as it produces less waste and protects the environment.

Our oil filters, manufactured under the strict quality guidelines of the original manufacturer, guarantee greater motor protection and therefore, greater durability.

Millard Fuel Filters retain solid particles and water from fuel, ensuring the clean flow of gas-oil or petrol to the motor.

Millard Fuel Filters are in charge of the retention of impurities which are mixed with fuel. The paper these filters use resists the passage of impurities because, otherwise, these would block the fuel's passage to the motor, damaging the carburettor or the electronic injection system.

Diesel motors are more demanding for fuel filtering than petrol, as particles, sulphur and paraffin - and above all water suspended in petrol - damage the injector’s nozzles and the pump itself.

Filters for carburetion vehicles generally have a plastic case. The quality of these filters is important as they possess metallic components internally. If these components are not processed adequately, they could become rusty and block the fuel line.

Filters for electronic injection are positioned in a place where only specialists can replace them, as the system's fuel line is pressurised. Most electronic injection filters are made of metal in order to resist the high pressure they suffer.

The Millard® Cabin Filter is an air filter which is, in a way, similar to the motor air filter. However, it is manufactured with different material, with the main materials being woven fibre and its “activated” carbon layer.

As in the case of some air filters, the filtering element has an electrostatic load, which means it is produced with particles which have already been treated with a positive or negative static charge. Particles in the environment are charged positively or negatively, so they are attracted to filtering particles with opposing charges. Additionally, the filter carries out a mechanical filtration; this means that the filtering element with pores of a specific size traps particles which are larger than the size of these pores.

The carbon layer eliminates odours. The carbon is “activated”, and this means that it is treated with chemicals and heat to provide it with specific odour-control features. Activated carbon traps gases producing odours by adsorption (not absorption), keeping them on the material's surface. Due to the fact that activated carbon is porous, each pore has an exposed surface, and the filter thus has a high capacity to trap dangerous gases.

Millard® Cabin Filters are designed to provide better protection against damaging pollutant agents and provide cleaner, purer air, eliminating pollen, undesirable particles and damaging gases, ensuring better air quality within a vehicle. If this kind of filter is not replaced regularly, the cabin’s air is not renewed, and impurities such as dust and pollen are not eliminated. Although it does not affect the vehicles safety directly, this can bring the driver allergies and thus cause an accident

The purpose of Millard’s Water/Gas-oil Separator Filters is to retain impurities and separate water which diesel fuel contains as a consequence of condensation due to temperature changes. We thus avoid damage which water can cause on injection systems and motor parts.

The filter separates drops of water which fuel contains and these are accumulated at its lower part so that they can be emptied every once in a while using a screw or purge valve.

It is essential for your motor's life that water does not enter the motor as it could cause irreparable damage. Our separating filters are manufactured following the highest quality standards and provide safety as they are protecting your motor at all times.

Millard Coolant filters help the refrigeration system to be cleaned of rust and other impurities, and also contain the chemical DCA4 (an supplementary coolant additive) which is released in a controlled manner and provides the suitable level of coolant additive to absorb heat from motor parts in order to disperse this heat subsequently in the air as it passes through the radiator. This is an essential component for the motor’s optimal operation.
