Cambustion Hall 8 / D12

Exhibitor Profile

The Aerodynamic Aerosol Classifier has been adopted globally for its unique ability to classify aerosol particles by aerodynamic diameter.

Selecting truly monodisperse aerosol over the unprecedented size range of 25nm – 5µm, the AAC is ideal for penetration studies and aerodynamic size distribution measurement. With no need to charge the particles, AAC output is free from multiple charging artefacts, which affect DMAs. Software upgrades in 2019 allow continuous (vs step) scans, for shorter scan times with significantly higher spectral resolution.

The DMS500 provides the fastest real-time electrical mobility size/number distributions available (from 200ms T10-90% at 10Hz); measuring from 5nm – 2.5μm, with unrivalled time response, sensitivity and sizing accuracy across the entire size range, with a single measurement technique. Applications include ambient monitoring, combustion aerosol and workplace measurements. A new catalytic stripper option (removal of volatiles) further enhances the DMS500’s integrated sampling and conditioning options, enabling both ambient measurements and direct sampling of rapidly-changing, high concentration aerosol sources.

Cambustion have launched the Dual Diluter system allowing automated upstream / downstream measurements of particle concentration for filter efficiency testing.

Cambustion AF10 Aerosol Flowmeter – The new flowmeter designed to measure gas flows containing aerosol particles

This new flowmeter is designed to measure gas flow rates, even when the gas contains (solid, liquid or mixed) aerosol particles. Unlike other popular flowmeters, the AF10 is not damaged by aerosol particles and does not modify the properties of the aerosol. The wide range of measurable flows – spanning two orders of magnitude, from 0.1 to 10 lpm – makes the AF10 well-suited for monitoring challenge aerosols used in filtration studies. Compatibility with a number of common carrier gases further increases its versatility.

Measurements rely on the well-established principle of pressure drop across an orifice, with fully automatic correction for temperature and pressure. An integrated cleaning brush actuated by a solenoid ensures that measurement accuracy is maintained even during prolonged experiments by removing accumulated material in less than 1 second. The straight-through tube design minimises particle losses, while the user-changeable orifices allow the pressure drop to be adjusted for minimally invasive measurements.

As a plug & play instrument, the AF10 is an invaluable tool which can be easily integrated (via USB and Ethernet interfaces) into numerous experimental setups, including filtration experiments. The large touchscreen display further contributes to the intuitive usability.

A traceable calibration certificate guarantees the accuracy

Insights into filtration performance of ISO 16890 and ISO 29463 air filter media using DEHS particles classified by aerodynamic diameter

S. Payne, J. Symonds, Cambustion Ltd, UK

Conference Session: G08 - Poster I - 2023-02-15 - 14:45

Filters used in heating, ventilation and air-conditioning (HVAC) systems are categorised by ISO 16890 depending on the fractional efficiency for aerosol removal during testing measured using an Optical Particle Counter (OPC). ePM1 results are reported for DiEthylHexylSebacate (DEHS) particles with particle diameters of 0.3 µm – 1 µm. Higher efficiency filters (such as those intended for hospitals and clean room environments) are categorised by ISO 29463 based on the most penetrating particle size determined in the range 0.04 µm – 1 µm using monodisperse or polydisperse test aerosols and a Condensation Particle Counter (CPC) to detect the smallest particles. This submicron particle size range is of major public concern due to potential penetration through the respiratory system and negative effects on human health.

An ideal instrument for detailed characterisation of air filter media is the Aerodynamic Aerosol Classifier (AAC), which offers substantially higher particle transmission efficiency than electrical mobility techniques and elimination of multiple charging issues (Payne et al. 2018). The AAC selects truly monodisperse liquid or solid particles without charging from 0.025 µm to >5 µm, by passing aerosol between rotating concentric cylinders with a coaxial sheath flow. In conjunction with a CPC, the AAC can also conduct high resolution scans of polydisperse particle size distributions in aerodynamic space, which is the most relevant metric for aerosol flow through filters and particle capture by interception or impaction.

In this study the filtration properties of commercial air filter media adhering to different categories in ISO standards 16890 and 29463 were evaluated in detail. Polydisperse DEHS particle size distributions up-and downstream of the filter samples were recorded over a broad size range, using a continuous scanning AAC procedure (Payne et al. 2019)....
