Clean Room Testing & Validation

Generators

Atomizer Aerosol Generator ATM 226

An aerosol generator for producing a test aerosol with defined characteristics especially for qualitative tests of filters for suspended matter (HEPA and ULPA filters), function test at laminar flow boxes and acceptance measurement in clean rooms. 

Compared to Atomizer Aerosol Generator ATM 220 or ATM 225 this instrument features a compact stainless steel housing (easy-to-clean), a direct connection with mains supply and a higher mass output. 

It produces aerosols with known properties in accordance with the guideline VDI 3491. The generated polydisperse aerosols are mainly in the size range 0.2 to 0.5 µm with a very high permanence of the particle size distribution and a defined and high particle number concentration.

CFG 290

Topas’ Condensation Fog Generator is a hand-held instrument that generates a dense and highly-visible fog made from polyhydric alcohol and purified water droplets.  The fog produced is sterile, non-toxic and free of oil and grease.  Because of these attributes, it is particularly useful when visualizing and tracking the air flow in clean room settings.

Diluters & Conditioners

Dilution System for Aerosols DIL 554

The dilution system is designed to accurately dilute aerosols to produce a defined particle concentration and carry out certain measuring tasks.

The main application of the dilution system DIL 550 is in the verification of test aerosols for testing clean rooms. Compared to the DIL 550 the innovative features are an easy-to-clean compact stainless steel housing and a mobil use by battery-operation (optional also wall power supply). 

By using the dilution system DIL 554 upstream of a particle counter, e.g. LAP 340, a dilution factor of up to 100 can be achieved. Thereby particle concentrations of >106 Particles per cf (1 cf = 28.3 l) can be reduced to 104 cf–1. This will put the particle concentration well within the range of standard particle counters.

Thereby particle concentrations of  >106 Particles per cf (1 cf = 28.3 l) can be reduced to 104 cf–1. This will put the particle concentration well within the range of standard particle counters.

Topas

HDS 561

The HDS High Dilution System is used for measuring very high concentration aerosols.  This instrument has a wide range of dilution ratios, adjustable from 1:100 to 1:100,000.  The flow-rate is customized by Topas and adaptable to different volumes, from 28 l/min, up to 100 l/min.

Topas

DIL 540

The DIL 540 Dilution System is a battery operated version of the popular DIL 550 series diluters and is available in either 10:1 or 100:1 dilution ratio versions at 28 l/min

Topas

ADD 536

The Aerosol Distribution and Dilution System, ADD 536, is used in conjunction with an aerosol generator and provides a uniform test aerosol from six different outlet ports with a defined source flow which can be used for verification of operating room protection.
