Produkteinführung

This aerosol generator atomizes a compatible test liquid into a repeatable droplet aerosol for filter leakage testing, cleanroom qualification and laboratory work. A corrosion-resistant reservoir, precision nozzle assembly and adjustable air supply provide controlled output without exposing the liquid to unnecessary contamination. Portable configurations use an internal pump, while compressed-air versions offer high output for larger air-handling systems.

Key Features

Stable droplet output supports repeatable upstream challenge concentrations.

Adjustable generation rate adapts to cabinets, terminal filters and larger duct systems.

Stainless-steel reservoir and cleanable nozzle path simplify changeover between compatible liquids.

Portable internal-pump options operate where a compressed-air connection is unavailable.

Visible liquid level and protected fill port reduce handling errors during field work.

Compact construction allows placement close to the intended aerosol injection point.

Kunden Produktbedenken

Field aerosol generation must hold the target challenge concentration despite limited injection space or air supply while allowing the reservoir and liquid path to be cleaned fully between test fluids.

An unstable aerosol challenge can make leak-test results difficult to compare.Regulated atomizing air and repeatable nozzle settings provide a controlled generation rate after warm-up.

Residual test liquid may contaminate the next application.A drainable stainless reservoir and accessible nozzle path support documented cleaning between liquids.

Field locations may not provide suitable compressed air.Select a battery-powered internal-pump configuration for independent portable operation.

Excessive aerosol can overload the downstream photometer or particle counter.Adjustable output and staged nozzle activation allow the operator to approach the target concentration gradually.
