Air Intake Filter Test System

The Automated Dust Loading Test rig ABP 115 enables standardized testing of industrial and engine air filter in accordance with ISO 5011. Suction pipes and other parts of the intake tract can also be characterized in the following parameters:
● Differential pressure related to air flow rate
· Differential pressure of the filter
· Restriction (relative pressure against ambient)
● Dust loading capacity (related to differential pressure increase, e.g. 20 hPa)
● Gravimetric efficiency
Through additional modules water tests can be performed to test samples to examine and characterize the test sample.
Pressure Tests are also possible. The dust generator SAG 420 is placed on a scale to control the dispensed dust mass flow. SAG 420 and the scale are located in a housing on a movable frame. The frame can be positioned in the required height of the specimen.
 
Features
 ◆ Powerful two-stage generation of the volume flow
◆ Precise flow rate measurement with adjustment for every application (ISO 50100)
◆ Modular design: components selected according to specific test requirements
◆ Regulated gravimetric dust dosing
◆ High level of automation, mostly automated test procedures with complete operator guidance, data handling and protocols
 
Optional
 Stabilization vessel with different connection flanges
Additional pressure sensors for measuring complete air inlet systems
Water injection system and water separators
Particle measuring equipment
Universal panel filter holder
Dust disperser SAG 410 for soot
Scavenging line
