PERSONALIZED CARE
Comprehensive filtration for engines in any type of machinery
The engine is the heart of any machine, and its reliability depends largely on effective filtration. Specialized filtration systems protect each critical component from harmful contaminants, ensuring high performance and preventing premature wear.
At Filtros Castelló, we offer comprehensive filtration solutions for engines, covering air, oil, fuel, coolant, and ventilation, with options tailored to different configurations and performance requirements.
They remove dust, sand, and abrasive particles, ensuring pure oxygen and protecting pistons and turbochargers.
Oil filters that trap metal debris and particles, extending the engine's service life.
Fuel filters and water separators that prevent corrosion and clogs in injectors and pumps.
Coolant filters that remove deposits and rust and release additives to prevent overheating.

KEY COMPONENTS
Filters that improve engine reliability
Each filter plays an essential role in the engine: from keeping the air clean and ensuring proper lubrication to guaranteeing fuel purity, proper thermal management, and balanced ventilation. Together, they maximize the durability and continuous performance of the machinery.
Engine air filter
It ensures clean combustion, preventing damage to pistons and turbochargers thanks to a constant supply of pure oxygen.
- Panel
- Cylindrical
- Oval-shaped
- Conical
- Cyclonic prefiltration
Oil filter
It cleans the lubrication system by trapping metal particles, dust, and combustion byproducts, keeping the engine in top condition.
- Standard oil filters
- Bypass filters
- Removal of water and fine particles
Fuel filter and water separator
It removes contaminants and condensation from the fuel tank, protecting injectors and pumps in high-pressure engines, especially diesel engines.
- Standard Fuel Filters
- Water Separators
- High-pressure systems (common rail)
Refrigerant filter
It removes deposits and releases additives in a controlled manner to keep the engine rust-free and prevent overheating.
- Standard Refrigerant Filters
- Filters with built-in additives
- Corrosion Protection Systems
Crankcase ventilation filter
It filters blow-by gases, separates oil particles, and reduces internal crankcase pressure, thereby improving performance.
- Closed ventilation filters
- Open ventilation filters
- Oil Separation Systems
WHAT INDUSTRIES DO WE WORK IN?
Why is a good engine filtration system important?
A high-quality filtration system is essential for protecting the engine from contaminants that can enter through the air, oil, or fuel. When these contaminants are not properly filtered, internal wear increases, performance decreases, and the likelihood of costly breakdowns rises.
With filters specifically designed for each type of machinery, the engine is guaranteed to receive clean airand oil free of impurities and fuel in perfect condition, preventing engine seizure, loss of power, and overheating.
For any company that relies on its equipment, maintaining a engine filter in optimal condition is one of the most effective ways to ensure productivity and extend the service life of the machinery.

Frequently Asked Questions About Engine Filters
We'll answer your questions
How often should I change the engine filters?
The frequency depends on the type of machinery, operating hours, and environmental conditions. In environments with dust, humidity, or heavy loads, filters should be inspected and replaced more frequently to prevent breakdowns and loss of performance.
What happens if an engine filter is dirty or clogged?
A dirty filter reduces the flow of air, oil, or fuel, leading to a loss of power, increased fuel consumption, and accelerated wear on the engine’s internal parts. In extreme cases, it can cause serious malfunctions or unexpected breakdowns.
How do I know which filter my machinery needs?
Most require air, oil, fuel, hydraulic, and cabin filters. Some equipment also uses transmission, coolant, or urea (AdBlue) filters.
