4 Liter Pressure Filter
STANDART: BS 598-102, EN 12697-1
LT-AS1510 Pressure Filter| 4 Liter
The 4 Liter Pressure Filter supports filtration procedures used for determining the soluble binder content of bituminous mixtures. The pressure vessel forces extraction liquid through the filter medium under controlled air pressure, helping laboratories perform binder extraction and mineral matter recovery efficiently.
- 4 litre capacity: Provides sufficient volume for routine asphalt extraction procedures.
- Pressure-assisted filtration: Forces extraction liquid through the filter paper under controlled pressure.
- Plated steel pressure vessel: Provides a robust structure for regular laboratory use.
- Integrated pressure gauge: Allows the operator to monitor working pressure during filtration.
- Filter support system: Holds the filter paper securely during operation.
- Faster filtration: Pressure-assisted operation reduces filtration time compared with gravity filtration.
- Optional foot pump: Provides the required air pressure without a separate powered compressor.
- Optional accessories: Test sieve, filter paper and filter filler funnel can be supplied separately.
- Binder content applications: Suitable for asphalt extraction and soluble binder analysis.

What Is a 4 Litre Pressure Filter?
The 4 Litre Pressure Filter supports laboratory procedures used to determine the soluble binder content of bituminous mixtures. During asphalt extraction, the system allows solvent-containing liquid to pass through a filter medium under controlled pressure.
Pressure-assisted filtration helps separate fine mineral particles from the extraction liquid. Therefore, laboratories can perform binder-content analysis under more controlled and efficient conditions.
Liya Test describes the unit as a plated steel pressure vessel fitted with a filter support and pressure gauge.
Pressure-Assisted Filtration
The extraction liquid is introduced into the pressure vessel and passed through the filter paper using compressed air.
Compared with gravity filtration, controlled pressure can significantly accelerate liquid passage through the filter medium. The operator monitors the applied pressure through the integrated gauge throughout the process.
BS 598-102 describes the use of a pressure filter with oil-free air during binder extraction procedures and specifies pressure-assisted filtration of extraction solutions.
4 Litre Steel Pressure Vessel
The unit provides approximately 4 litres of working capacity. Its plated steel construction creates a durable pressure-resistant body suitable for routine asphalt laboratory applications.
The fitted cover and filter support help maintain the filtration assembly in the correct position during operation. This simple mechanical construction also facilitates routine cleaning and preparation between tests.
Pressure Gauge and Filter Support
An integrated pressure gauge allows the operator to observe system pressure continuously.
The internal filter support holds the filter paper while extraction liquid passes through it. Appropriate filtration helps retain fine mineral material while allowing the solvent-binder solution to pass through the system.
Consistent pressure control also helps laboratories reproduce similar filtration conditions between different samples.
Optional Laboratory Accessories
A foot pump, test sieve, filter paper and filter filler funnel are available separately for the Pressure Filter. Liya Test lists these components as optional accessories rather than standard equipment.
The foot pump provides a practical source of air pressure where a laboratory compressor is not required. Test sieves and filter media support the separation and recovery of mineral material during binder analysis.
Asphalt and Binder Content Applications
The Pressure Filter is suitable for asphalt production laboratories, highway laboratories, universities and quality control facilities.
It is particularly useful as part of extraction workflows used to determine soluble binder content and recover mineral fines from bituminous mixtures.
Testing According to EN 12697-1 and BS 598-102
The 4 Litre Pressure Filter supports procedures associated with EN 12697-1 and BS 598-102. EN 12697-1 addresses soluble binder content determination in bituminous mixtures, while BS 598-102 includes pressure filtration within binder-content analysis procedures.
Overall, the 4 Litre Pressure Filter combines a robust steel vessel, controlled pressure filtration and integrated pressure monitoring. Therefore, asphalt laboratories can perform extraction-liquid filtration efficiently and consistently.
