Owning a crossover from Renault implies not only the pleasure of traveling, but also responsibility for the state of the life support systems of the cabin. Salon filter It is one of the key elements in ensuring the health of the driver and passengers by trapping dust, pollen and toxic substances. In the second generation model known as the Duster 2 (or Duster 1.2 after the first generation restyling), the approach to maintaining this unit has its own technical features, which are important to consider when self-repairing.
Ignoring timely replacement can lead to reduced efficiency ventilation And the appearance of unpleasant smells. Many owners mistakenly believe that access to the air purification element is difficult and requires the removal of the dashboard, but in reality the procedure is much easier. The correct approach allows you to perform all the necessary manipulations in 15-20 minutes without contacting the service center.
In this article, we will analyze in detail the process of selecting consumables, determine the exact location of the case and describe the algorithm of actions. You will learn how to avoid common installation errors and why the direction of airflow is critical. Proper maintenance of the air conditioning system will prolong the life of the fan and keep the evaporator clean.
The role of air filtration in climate control
The main task of the cleaning element is to create a barrier between the external environment and the interior space of the car. In urban operation or traffic on dirt roads, the concentration of suspended particles in the air reaches high values. Filtering element It traps dust, soot, plant spores and small debris, preventing them from settling on the surfaces of the cabin and getting into the lungs of occupants.
There are two main types of consumables used for the model Renault Duster 2. Conventional paper filters effectively fight large dust, but pass gases and smells. Coal modifications contain a layer of activated carbon that adsorbs harmful compounds such as nitrogen and sulfur oxides, as well as unpleasant exhaust aromas in traffic jams.
⚠️ Note: Using unoriginal low-quality filters with poor geometry can cause the raw air to be sucked past the filter element, reducing the efficiency of the entire system to zero.
Regular replacement ensures optimal system capacity. When the cells are clogged, the airflow resistance rises, which causes the fan to work with increased load. This can lead to premature wear of the electric motor of the stove and a decrease in overall performance. climate-set.
Replacement frequency and signs of contamination
The manufacturer recommends that the ventilation system be maintained every 15,000 kilometers or once a year, whichever comes first. However, the real conditions of operation in megacities with dense traffic and high dust levels dictate their rules. In such cases, the interval of substitution consumables It is advisable to reduce to 7-10 thousand kilometers.
The need for urgent replacement can be determined by a number of indirect signs. If you notice that the airflow from the deflectors has become weaker even at the maximum speed of the fan, this is the first signal of contamination. Also an alarming symptom is the appearance of fogging of glasses in wet weather, which does not go away for a long time.
- 🌫️ The appearance of a persistent unpleasant smell of dampness or rot when the blower is turned on.
- 💨 Reducing the intensity of air flow at all speeds of the fan.
- 🌫️ Frequent fogging of windows in rainy weather, even with the air conditioner running.
- 🌫️ The appearance of dust on the dashboard immediately after the start of movement on the highway.
Visual diagnostics also provide results. If you take out an old element and look at it in the light, it will look dark and dense. Unlike a new white or light gray product, the contaminated filter loses its properties and becomes a breeding ground for bacteria.
Selection of the appropriate filter element
The auto parts market offers many options for the model Duster 2. The original from Renault usually has an article beginning with the prefix 7701, however, there are qualitative analogues from well-known manufacturers such as Mann-Filter, Mahle or Bosch. When choosing, it is important to pay attention to the overall dimensions, since even a small deviation of a couple of millimeters can make installation difficult.
Coal filters are usually gray or black and are more expensive than paper counterparts. Their use is especially important for residents of large cities, where the level of air pollution is high. Paper options are suitable for regions with clean ecology and rare traffic jams, where the main threat is road dust.
When buying, pay attention to the thickness of the end sealing sponge - it should be dense enough to exclude air passage along the perimeter.
The table below compares the popular options available for installation on the second generation Duster:
| Brand | Type | Article (example) | Features |
|---|---|---|---|
| Renault (Original) | Coal | 7701063837 | Perfect geometry, high price |
| Mann-Filter | Coal | CUP 1936 | High dust capacity, antiallergen |
| Bosch | Paperwork | 1 987 432 456 | Affordable price, standard protection |
| Nevsky Filter | Coal | NFC-1000C | Budget option, average quality |
When purchasing products of unknown brands, you should be careful. Cheap analogues often have insufficiently dense padding, which is why the filter material can be deformed under the pressure of the air flow. This will cause the air to follow the path of least resistance, bypassing the purification.
Localization and access to the filter body
Unlike many modern cars, where access is carried out from the hood, the Renault Duster 2 The filter is located inside the cabin. The exact location of its location is the right part of the front panel, in the leg area of the front passenger. This decision of the engineers of the French concern is dictated by the features of the layout of the engine compartment.
To start work, it is necessary to move the passenger seat as far back as possible to provide convenient access to the side surface of the center console. You will need good lighting, as the installation area is in the depth of the niche and poorly illuminated by standard light sources. Using a headlamp or a powerful flashlight will greatly facilitate the process.
⚠️ Warning: Before starting work, make sure that the car is on a flat surface and the ignition is turned off. This will eliminate accidental fan activation during maintenance.
Access to the lid of the case is closed with a plastic decorative panel or carpet pocket, depending on the configuration of the car. In some versions, you may need to remove the side plastic torpedo lining, which is held on the clips. You need to act carefully so as not to damage the fixers.
Do I have to take off my glove compartment?
In most cases, to replace the filter with Duster 2, you do not need to remove the glove compartment (dressbox) completely. It is enough to access the right end of the console. However, if you have additional noise insulation or non-standard media installed, access may be difficult.
Step-by-step instructions for dismantling and installation
The replacement process does not require complex special tools. You will only need a cross screwdriver (in some cases) and possibly a flat screwdriver for gently removing plastic stubs. The main thing in this operation is the sequence of actions and attention to the details of the design.
First, you need to open access to the end of the filter body. If a plastic cover is installed, it is usually fixed with one or two screws, as well as plastic latches. When you pull the lid, gently pull the lid on yourself. Try not to make excessive efforts to avoid breaking down age-related plastic.
☑️ Replacement algorithm
Removing an old item may require some dexterity. The filter is inserted into the guides quite tightly. You need to take over the edge of the frame or for a special tongue and pull it on yourself, swaying slightly from side to side. If the filter is very swelled from moisture, it can come out with difficulty - in this case, it can be gently tampered with a flat object.
Installation of the new filter is performed in reverse sequence. It is critically important to observe the direction of the air flow, which is indicated by the arrow on the end of the new product. The arrow should look down or towards the cabin (depending on the specific modification of the body, usually markings). AIR FLOW -> DOWN or similar. Incorrect installation will dramatically reduce the efficiency of cleaning.
The key point of replacement is the correct orientation of the airflow arrow: it should indicate the direction of air movement from the fan to the cabin.
After installing the frame with the new filter, check the density of the lid. It should stand in place with a characteristic click or tightly pressed screws. Make sure there are no gaps left through which untreated air could enter the system.
Cleaning niches and system maintenance
During operation in the niche where the filter is located, garbage inevitably accumulates: leaves, dust, small debris. An audit of the space is strongly recommended before installing a new element. Using a vacuum cleaner with a narrow nozzle will remove the bulk of the contaminants.
If you find traces of mold or feel a persistent smell of dampness, a simple vacuum cleaner will not be enough. In this case, it is advisable to treat the inner surfaces of the niche and visible parts of the evaporator with a special antibacterial spray for automotive air conditioners. This will help to eliminate the source of the unpleasant smell.
- 🧹 Carefully vacuum the niche before installing a new filter.
- 🧹 Wash the available surfaces with a wet (not wet) wipe.
- 🧹 If necessary, use a plastic foam cleaner.
It is also worth checking the condition of seals on the lid of the case. If a rubber or foam seal has become unusable, it can be replaced or restored with a self-adhesive sealer. This will ensure the tightness of the contour and eliminate the sucking of dirty air.
Typical mistakes and expert advice
Despite the simplicity of the operation, beginners often make mistakes that can negate all efforts. One of the most common is ignoring the labeling of the direction of flow. Installing the filter “back-to-back” will cause the dust to quickly clog the working surface, and the resistance will increase.
Another mistake is trying to force the filter if it doesn’t come in. If the new element does not fit in, then the wrong size or model is chosen. Do not touch the edges or bend the frame, as this will violate the integrity of the filter material. It is better to spend time searching for the right article.
⚠️ Warning: Never leave the body open or with a loosely closed lid. This is a direct route for large debris to the ventilation system, which can lead to a stove fan jamming.
Some owners try to wash and dry disposable filters for reuse. This cannot be done categorically. The paper base is destroyed by water, and the coal layer loses its properties. After drying, this filter turns into a source of dust and bacteria.
To extend the service life of the new filter, you can slightly spray its exterior with an antistatic spray before the first installation, which will improve the adhesion of fine dust.
Compliance with replacement technology and the use of quality consumables guarantee clean air in the cabin of your cabin. Renault Duster.. Regular maintenance of a ventilation system is an investment in your health and comfort while traveling.
Can I install a filter from other Renault models?
Yes, filters from Renault Logan 2, Sandero Stepway or Kaptur with a similar engine are often suitable, but be sure to check the geometric dimensions. Article 7701063837 is standardized for many B0 platform models.
How often should I change the filter in the summer?
In summer, during the flowering period of plants and high dust content, the filter resource is consumed faster. It is recommended to check his condition every 5-7 thousand km, especially if you often drive on primers.
What to do if there is a smell after the replacement?
The smell may not come from the filter, but from the air conditioner evaporator. In this case, professional cleaning of the system with disassembly or use of special equipment (foam cleaning) is required.
Does the filter affect fuel consumption?
Indirectly. A heavily clogged filter causes the fan to work harder, increasing the load on the generator and engine, which can slightly increase fuel consumption.
