Product Details

Automated Filter Tester Model 3120 meets NIOSH’s proposed Powered Air Purifying Respirator (PAPR) filter test requirements. It is an oil-only tester that has an airflow range of 100 to 200 L/min and can measure efficiencies up to 99.999%, or penetrations as low as 0.001%. In fact, Model 3120 uses the same proven oil-aerosol generator found in models 8127 and 8130. Like models 8127 and 8130, Model 3120 features dual light scattering photometers that simultaneously measure upstream and downstream particle concentration to ensure fast, repeatable results.

Applications

Automated filter testing

Features

◆ A touch-panel display makes the Model 3120 easy to use, so very little operator training is needed. On-screen menus enable users to easily change test parameters to meet specific requirements of different filters. A microprocessor controls the tester and calculates and displays filter penetration, resistance value and flow rate. Self-check diagnostics and automatic zeroing between tests ensures accurate, stable, and reproducible results.

◆ Compliance with respirator regulations

◆ Simple, fast and automated operation

◆ Service and support

Components

Dust removal system:

The compressed filtration air system provides a certain amount of testing dust for the aerosol generator

The test chamber:

Main test chamber and sample clamp

Monitoring and regulating system:

Pressure monitoring and adjustment provide dynamic test environment

Results display and analysis system:

Monitor through aerosol and display test results
