Microfilters

Microfilters and filtering spare parts

GESPASA develops advanced filters that ensure fuel cleanliness and the protection of pumps, meters and control equipment, thanks to the effective removal of impurities, water and bacteria.

Their robust construction and high efficiency make them an ideal solution for both fixed and mobile installations where consistent quality is required in the supply.

High-efficiency microfilters
The FG 100 is a 5 µm microfilter especially suitable for diesel, petrol, kerosene and AVGAS/Jet A-1.
It combines performance and operational visibility by integrating water-repellent filtering paper in an aluminium housing with a transparent body, making quick visual inspection of the element condition easier.
Its separation capacity removes up to 93 % of the water present in the fluid, ensuring a clean supply even in demanding conditions.
The filter works with flow rates of up to 105 l/min, supports maximum pressures of 5 bar and temperatures between −10 °C and +50 °C.
In addition, it incorporates a drain valve for sediment drainage, simplifying maintenance without the need to interrupt the system.

The FG 300 and FG 450 models are designed for staged filtration within high-efficiency microfiltration systems, suitable for diesel and liquid fuels in general, providing greater safety and quality in the cleaning process.
Although no specific datasheets are available for FG 150 and FG 1000, both are part of the same range, with progressive filtration capacities and housings adapted to different flow rates and to demanding operating environments.

Recommended applications
As intermediate protection in storage plants, supply logistics operations or in upstream connections to pumps and meters, to ensure fluid preservation and maintain the integrity of downstream equipment.

FG 150 diesel filter - 150 l/min

The FG 150 is an in-line filter designed specifically for diesel filtration in supply systems with flow rates of up to 150 litres per minute.
Its function is to protect hydraulic components, such as pumps and meters, by preventing the entry of impurities, solid particles and residues present in the stored fuel. With a 50-micron filtration rating, it ensures effective retention without penalising the flow rate.

Made with a durable housing and 1” threads, the FG 150 is suitable for fixed or mobile installations, either before or after the pumping point, and is compatible with multiple supply configurations.

This filter acts as a first protective barrier for agricultural, industrial or logistics installations, where maintaining fuel purity is essential to preserve equipment efficiency.

Its compact design makes maintenance and replacement of the filter element easier, reducing intervention times.
By integrating the FG 150 into a supply circuit, the risks of blockage, premature wear or breakdowns in pumping systems are minimised, ensuring safer and longer-lasting operation of the entire installation.

Technical specifications
Application: diesel
Maximum flow rate: 150 l/min
Connections: 1” thread
Filter type: in-line
Use: protection of pumps, meters and dispensers
Installation: before or after the pump unit
Maintenance: replacement filter cartridge

FG 300 diesel filter - 300 l/min

The FG 300 is a high-capacity filter for diesel, designed to protect supply systems operating with flow rates of up to 300 litres per minute.
Its 50-micron filtration rating makes it possible to retain solid particles that could damage sensitive components such as pumps or volumetric meters, ensuring an efficient operation free from impurities.

With 1”½ threaded connections, the FG 300 adapts to industrial installations with high volumes, where a reliable pre-filtration solution is required without compromising the operating flow rate.

This filter is installed in-line and can be fitted on either the suction or discharge side of the system, depending on the specific requirements of the hydraulic design.

Its durable metal structure and replaceable cartridge system make periodic maintenance easier, improving the service life of the connected equipment.

Ideal for logistics plants, agricultural cooperatives, fleet depots and private service stations, the FG 300 provides essential protection in environments with a high volume of operations.

Technical specifications
Application: diesel
Maximum flow rate: 300 l/min
Connections: 1”½ thread
Type: in-line filter
Function: protection of hydraulic equipment (pumps, meters, dispensers)
Installation: suction or discharge
Maintenance: replaceable cartridge

FG 450 diesel filter - 450 l/min

The FG 450 is a large-capacity filter for diesel circuits, especially designed for high-flow systems operating at up to 450 litres per minute.

With a 50-micron filtration rating, it effectively protects supply equipment against solid residues, extending the service life of pumps, meters and critical hydraulic components.

Thanks to its 2” threaded connections, this filter is ideal for integration into industrial installations, distribution tanks or fast-loading stations, where high flow requires a robust solution with low pressure drop. Its in-line mounting makes it versatile, allowing it to be fitted before or after the pump, depending on the system architecture.

Manufactured with materials resistant to continuous use, the FG 450 allows safe and reliable operation even in demanding environments.
Its replaceable cartridge system simplifies maintenance tasks, ensuring quick cleaning and long-lasting operation.
It is the right solution when seeking protection and efficiency in high-volume installations.

Technical specifications
Application: diesel
Maximum flow rate: 450 l/min
Connections: 2” thread
Type: in-line filter
Installation: suitable for suction or discharge
Maintenance: easy replacement of the filter cartridge
Recommended use: industrial installations, cooperatives, heavy-duty fleets

FG 1000 industrial filter - 1000 l/min

The FG 1000 is the highest-capacity filter in the GESPASA range for diesel filtration, designed to operate in very high-flow installations, up to 1000 litres per minute. Its robust design with 3” threads allows direct integration into high-volume systems, offering effective protection against solid particles by means of a 50-micron filtration rating.

It is especially suitable for logistics infrastructures, distribution plants, fleet bases and tanks with multiple loading lines, where maintaining fuel purity is key to preventing downtime and breakdowns.

The FG 1000 acts as a protective barrier for high-power pumps and high-performance meters, minimising contamination risks and increasing system reliability.

This filter incorporates a replaceable internal cartridge system, accessible and easy to replace, allowing periodic cleaning without prolonged interruptions.
