AGF 2.0 iP

AGF series aerosol generator with built-in pump

Categories: , , ,

Description

The AGF 2.0 iP aerosol generator is able to atomize liquids with a binary nozzle.

Unlike the other versions in the AGF series, the AGF 2.0 iP is equipped with a built-in pump that generates volume flow, making an additional compressed air connection unnecessary in order to operate the device.

Fig. 2 presents a schematic arrangement of the generator components.

Startup

A built-in pump suctions ambient air via a prefilter and directs it to a binary nozzle via a particulate air filter. The primary pressure on the nozzle is 0.6 bar above ambient pressure. The negative pressure in the nozzle suctions the liquid to be atomized from a reservoir, while the volume flow of this liquid is able to be adjusted using a needle valve that is incorporated into the nozzle.

Benefits

<span style="color:#008b57">•</span>    Exact adjustment of the operating parameters
<br> <span style="color:#008b57">•</span>    Number concentration (CN) can be varied by the factor 10
<br> <span style="color:#008b57">•</span>    Particle size distribution remains virtually constant, if CN is modified
<br> <span style="color:#008b57">•</span>    Number distribution maximum is within the MPPS range
<br> <span style="color:#008b57">•</span>    Virtually no power losses
<br> <span style="color:#008b57">•</span>    Optimal concentration, no coagulation losses
<br> <span style="color:#008b57">•</span>    Resistant to numerous acids, bases, and solvents
<br> <span style="color:#008b57">•</span>    Robust design, stainless steel housing
<br> <span style="color:#008b57">•</span>    Easy to operate
<br> <span style="color:#008b57">•</span>    As opposed to the collision method, the AGF 2.0 does not generate any particles > 2 µm thanks to its cyclone.
<br> <span style="color:#008b57">•</span>    Due to the fact that the AGF generates virtually no droplets > 2 µm, the consumption of materials is very low, thus ensuring a long dosing time.
<br> <span style="color:#008b57">•</span>    With the use of DEHS the mean particle size is within the MPPS range for HEPA/ULPA filters
