Application

G506 Automatic Filter Performance Tester is used fortestingprofessional filter material and filtration efficiencyof a wide range of air filters including HEPA and ULPA filter, respirator, filter cartridge and protective clothing test. It also can use salt or oil mist to test filter media. Rapid acquisition of filter media performance evaluation parameters, and accurate evaluation of filter material quality, performance, life and so on. It is convenientto userforacademic research and product developmentof new filter materials, product quality control, material performance verification.

Parameters

Accessoriess

Main Unit: As the core component of the testing instrument, it is responsible for overall control and data processing.

Aerosol Generator: Includes salt particulate aerosol generators and oil particulate aerosol generators, used to generate the aerosol particles required for the test.

Classifier: Utilizes the principle of inertia to collect unwanted large particles into a collection bottle, ensuring that the aerosol particles entering the testing system meet the requirements.

Particle Counter: Usually equipped with two units, used to measure the number or mass concentration of aerosols upstream and downstream of the filter media, and is a key device for calculating filtration efficiency. Some systems may use a laser scattering photometer instead of a particle counter.

Static Neutralization Device: Neutralizes the static electricity carried by the aerosols, reducing particle loss and the influence of static electricity on the test results.

Differential Pressure Sensor: Monitors the pressure drop across the filter media, assessing changes in resistance during the filtration process.

Flow Meter: Monitors the flow rate during the test, ensuring consistency of test conditions. Flow meters are typically 2.5 grade accurate, ranging from 10-100 L/min.

Vacuum pump: Provides the necessary negative pressure environment to ensure aerosol particles can smoothly enter the testing system.

Pneumatic clamps and protective devices: Employ pneumatic clamping, offering convenient operation and high safety, while also featuring protective devices to ensure safe use.

Programmable logic controller (PLC) and touchscreen: Enables automated control of the testing process, including control, monitoring, calculation, and data display functions. Some devices utilize a PLC control system and are equipped with a 7-inch color touchscreen.

Instruction manual and power cord: Provides an operation guide and power connection instructions to ensure users can correctly operate the equipment.
