- Air pre-filter EMAK K1600, K1250 Mistral L66150799 - dedicated foam pre-filter for Oleo-Mac and Mistral tractors. Effectively retains dust, grass and dust, extends the life of the engine and main filter, ensuring stable, economical operation
Pre-filter / air pre-filter for Oleo-Mac tractor OM 105/16 KH / OM 106/16 KH / OM 107L/16 KH / OM 92/16 KH / Mistral 72/12.5 KH
Preliminary air filter for engine EMAK K1600, K1250 Mistral L66150799 is a high-quality pre-filter made of durable foam, designed specifically to protect engines used in Oleo-Mac and Mistral garden tractors. Its task is to catch larger particles of dirt - dust, dust, grass and small plant debris - before they reach the main paper filter and combustion chamber. As a result, the engine runs cleaner, more stable and stays fully operational longer.
Proper air filtration is critical to engine life. This pre-filter model has been tailored to fit popular garden tractors such as Oleo-Mac OM 105/16 KH, OM 106/16 KH, OM 107L/16 KH, OM 92/16 KH and Mistral 72/12.5 KH, which guarantees secure installation and full compatibility with EMAK K1600 and K1250 drive units.
Where the pre-filter is installed L66150799?
The pre-filter is mounted directly on a standard air filter (usually paper) in the engine filter housing. It is worn over the main insert as an outer foam cover. Such a two-stage filtration system ensures more efficient retention of impurities and reduces the frequency of main filter replacement. Installation is quick and easy - usually all you need to do is remove the filter housing cover, apply the foam pre-filter and close the housing again.
Application of air pre-filter EMAK K1600, K1250 Mistral L66150799 includes primarily:
- Garden tractors and ride-on mowers working in home areas.
- Operation in dusty environments - dry lawns, fields, orchards, landscape gardens.
- Professional gardening services, where machines work many hours a day.
Regular replacement of the pre-filter and its periodic cleaning can significantly reduce the risk of engine seizure, loss of power or increased fuel consumption. This is a small cost compared to potential repairs to the drive unit.
AIR PREFILTER EMAK K1600, K1250 MISTRAL - MAXIMUM ENGINE PROTECTION IN ALL CONDITIONS

Durable foam material
The prefilter is made of strain-resistant filter foam with the right density. This material effectively traps larger dirt particles while not restricting airflow to the engine. This ensures that your machine does not lose power, even during long dusty work or when mowing very dry lawns.
Two-stage air filtration
The use of a foam prefilter in combination with a paper filter creates a two-stage filtration system. First the foam traps coarser dirt, then the main filter captures fine dust. In practice, this translates into:
- better protection for the cylinder, piston and rings,
- lower engine failure rate,
- stable speed and even operation even under heavy load.
Savings on service and spare parts
By using the pre-filter L66150799 regularly, you reduce the rate of fouling of the main air filter. This means less frequent paper filter changes and less risk of costly engine repairs. This is especially important for professional users who make intensive use of the tractor for gardening services or maintenance of green spaces.
Examples of daily applications:
- Mowing extensive, dry lawns in residential areas where floating dust quickly clogs the main filter.
- Work in orchards or on plots with sandy soil, where dust is particularly troublesome for the engine.
- Regular maintenance of areas around businesses, hotels or sports facilities where equipment reliability is key.
EASY INSTALLATION OF PREFILTER L66150799 IN OLEO-MAC AND MISTRAL TRACTORS

- After the season is over, easily clean or replace the pre-filter during basic home service, extending the life of the engine.
- In a horticultural company, where tractors work almost daily - the ability to quickly service filters minimizes downtime and wasted time.
AIR PREFILTER FOR EMAK K1600, K1250 MISTRAL ENGINE - DURABILITY AND RELIABILITY IN PRACTICE

High quality workmanship
The precise manufacture of the filter and the properly selected density of the foam make the product retain its filtering properties for a long time. The edges are even and the dimensions match the filter housings on popular garden tractors, minimizing the risk of leaks.
Resistance to intensive use
Pre-filter L66150799 was created for users who frequently and intensively use their machines. The foam's resistance to mechanical damage and deformation means that the filter retains its shape even after many installation, cleaning and removal cycles.
Stable engine operation and lower combustion
Clean air supplied to the combustion chamber means optimal combustion of the fuel-air mixture. In practice, this translates into:
- easier engine starting,
- more even, quieter operation of the drive unit,
- the ability to maintain lower fuel consumption with the same mowing performance.
Examples of situations where filter reliability is crucial:
- Mowing large acreages continuously - such as sports fields, parks, recreational areas.
- Work during the summer season, when the air is particularly dry and full of dust.
- Use of the tractor in construction or renovation areas where fine construction dust floats around.

2. How often should you replace the air prefilter?
Frequency of replacement depends on the intensity of use and operating conditions. For typical domestic use, it is recommended to check after every few mowings and replace every season or more often if the filter is visibly dirty. In professional work, the filter may need to be cleaned or replaced even every dozen or so hours of operation.
3. Can the prefilter be cleaned or must it always be replaced?
The foam pre-filter can be cleaned periodically (e.g., by blowing with compressed air or by gently rinsing and thoroughly drying), but after noticeable wear of the material or loss of shape, it is recommended to replace it with a new one to maintain full filtration efficiency.
4. Does the installation of a pre-filter require specialized tools?
No, installing a pre-filter is very simple and usually does not require any specialized tools. In most cases, it is enough to unscrew or detach the cover of the air filter housing, put the prefilter on the main filter and close the housing again.
5. What are the symptoms of a worn or clogged air filter?
The most common symptoms include a decrease in engine power, uneven rpm, difficulty starting, increased fuel consumption, and excessive exhaust smoke. If you notice such symptoms, it is worth checking the condition of the main filter and pre-filter first.
