SAG 440

The Dust Disperser SAG 440 has been especially developed to meet the requirements as defined by the guidelines ASHRAE 52.2 and DIN EN 779 for testing the performance of particulate air filters.

Due to the particular physical properties of ASHRAE test dust the instrument was adapted to this material. The SAG 440 is particularly suited for feeding / dosing dusts containing a certain proportion of fibres and provides excellent results when producing test dust to check separation efficiencies.

Advantages:

• Constant and reproducible dosing rate over a wide concentration range makes it suitable for several applications
• Continuous operation
• Refillable during operation – ideal for long term tests
• Optional remote control unit for manual or computer control

Applications:

• Ideal for testing the separation efficiencies of filters
• Aerosol preparation for the determination of the filter dust holding capacity according to EN779, ASHRAE 52.2
• Evaluation and calibration of dust samplers and monitors
