Dust Generator SAG 420

The Dust Feeder / Dust Disperser SAG 420 is a device for generating solid aerosols by transforming a powdered solid into the air-floating state and has a very large dosing range.

Standards

- dosing continuity of different dusts over a long period of time

- under operating conditions easy refillable

- mass flow control by weigh scale option

In applications where air-floating particles are required such as testing of the separation performance of filter media an aerosol with certain, well-defined characteristic features and stability over a period of time is to be used. If the aerosol is produced from a certain powder the characteristic features of the generated dust will be determined by the powder. Additional characteristic features of the aerosol are achieved by transferring the powder into the air-floating state. The process is divided into two parts: the continuous dosing of the powder mass flow and the dispersing (thinning out) of the powder preferably down to the primary particle size of the material.

Benefits

• dosing continuity of different dusts over a long period of time
• refill during operation
• mass flow control by weigh scale option

Applications

• charging of filters, filter media and separators with dust
• generation of dust to determine the fractional as well as the total separation efficiency
• visualization of air streams

Accessories

• movable rig SVE 430 for dust disperser SAG 420
• tripod holder
• hopper without dispersion nozzle to collect dosed dust – can be attached for weighing the dust and calibrating the device
• weigh option: optional scale available for mass flow control with a precision of 0.2 g/min that ensures exact feed over long periods of time, the generator is mounted on the scale in a vertically adjustable stand with housing
• Electrostatic Aerosol Neutralizer EAN 581 for discharging of the charged test dust
