Gespasa Filters

Filters (Microfilters and replacement kits)

GESPASA develops advanced filters that ensure fuel cleanliness and protection for 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 supply.

High-efficiency microfilters
The FG 100 is a 5 µm microfilter particularly suitable for diesel, petrol, kerosene and AVGAS/Jet-A1.
It combines performance and operational visibility by integrating hydrophobic filter paper in an aluminium housing with a transparent body, enabling a quick visual inspection of the element’s condition.
Its separation capacity removes up to 93% of the water present in the fluid, ensuring a clean supply even under demanding conditions.
The filter operates with flow rates of up to 105 l/min, withstands maximum pressures of 5 bar and temperatures between −10 °C and +50 °C.
It also features a drain valve for sediment removal, simplifying maintenance without needing to shut down 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 to the purification process.
Although specific datasheets are not 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 demanding operating environments.

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

Diesel filter FG 150 - 150 l/min

The FG 150 is an in-line filter specifically designed 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, preventing the entry of impurities, solid particles and residues present in the stored fuel. With a filtration rating of 50 microns, it ensures effective retention without penalising the throughput.

Manufactured with a durable housing and 1” threads, the FG 150 is suitable for fixed or mobile installations, whether 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 facilitates maintenance and replacement of the filter element, reducing intervention time.
By integrating the FG 150 into a refuelling circuit, blockage risks, premature wear or breakdowns in pumping systems are minimised, ensuring a safer and longer operation of the entire installation.

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

Diesel filter FG 300 - 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 filtration rating of 50 microns enables it to retain solid particles that could damage sensitive components such as pumps or positive displacement meters, ensuring an efficient and impurity-free operation.

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

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

Its robust metal structure and its replaceable cartridge system facilitate periodic maintenance, improving the durability 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 high operating volumes.

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

Diesel filter FG 450 - 450 l/min

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

With a filtration rating of 50 microns, 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 depots or rapid loading stations, where high flow requires a robust solution with low pressure loss. Its in-line mounting makes it versatile, allowing it to be placed before or after the pump, depending on the system architecture.

Manufactured with materials resistant to continuous use, the FG 450 enables a safe and reliable operation even in demanding environments.
Its replaceable cartridge system simplifies maintenance, ensuring fast cleaning and extended operation.
It is the right solution when protection and efficiency are needed in high-volume installations.

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

Industrial filter FG 1000 - 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, providing effective protection against solid particles with a filtration rating of 50 microns.

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

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

This filter incorporates a replaceable internal cartridge system that is accessible and easy to replace, enabling periodic cleaning without extended interruptions.

Its reinforced metal structure, together with the simplicity of in-line installation, makes the FG 1000 an essential solution for industrial operations that require high flow rates with guaranteed cleanliness standards.
