Clean Room Testing & Validation

Generators

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.

Topas ATM 240/L

The Topas ATM 240/L generates a high concentration aerosol from a suspension of polystyrene (PSL) particles, and is used for testing filters in sensitive areas such as those found in the semiconductor and aerospace industries.  The ATM 240/L has a particle production rate of up to 1.5 x 1011/min, scalable by suspension concentration and nozzle pressure.

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.

Topas Aerosol Generator ATM 228

The aerosol generator ATM 228 contains a brushless compressor, which means no external compressed air supply is required for operation.  Flow rate is controlled by a differential nozzle pressure control, allowing for a reproducible and stable generator operation, even at very low air flow rates and particle production rates.  The ATM 228 produces aerosol from pure liquids, solutions and suspensions.

Sampling & Dilution

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.

Dilution System for Aerosols DIL 550

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. By using the dilution system DIL 554 upstream of a particle counter, e.g. LAP 322, 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.

Topas Self-Adjusting Aerosol Diluter DIL 540/C

The aerosol diluter DIL 540/C self-adjusts to maintain the desired dilution factor despite changing operating conditions.  This mobile unit is particularly useful for the verification of test aerosols used for testing cleamroom installations.

Topas

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 322, 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.

Topas

Topas VDS 562

The Topas VDS 562 Variable Dilution System was developed so that users can lower the concentrations of highly concentrated aersol samples using a single diluter.  The instrument can be calibrated for vaious flow rates between 28.3 l/min-100 l/min, and dilution ranges up to 1:100,000 at the time of purchase.  The VDS 562 features negligible pressure drop and no external dilution air requirement.

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
