3990-02 high-efficiency leak detector generator for biosafety cabinets

3990-02 high-efficiency leak detector generator for biosafety cabinetsIt is a thermal and high-capacity aerosol generator. After injecting aerosol solution and turning on the machine, the internal heating element quickly transforms the liquid aerosol into a vapor state. With the assistance of inert gases (such as N2, CO2, etc.), the vapor is rapidly cooled to generate dispersed aerosol smoke output. Heating time as low as less than 2 minutes, high concentration aerosol output, widely used in filter leakage testing for small air purification units to large clean room air conditioning purification systems.

After the high-efficiency filter is put into operation, if there are leakage points or gaps due to insufficient installation, the predetermined purification effect cannot be achieved, and a leak test must be conducted on the high-efficiency filter. Due to the low concentration of atmospheric dust upstream of the tested high-efficiency filter, an aerosol generator needs to be used to supplement the dust to meet the testing conditions. By using a gas volume gel photometer to test the concentration of suspended particles upstream of the high-efficiency filter and conducting a uniform scanning test downstream, the leakage rate of the tested high-efficiency filter can be determined to determine whether there is leakage.

Mechanical level gauge displays oil level and allows for more intuitive observation of liquid level

Suitable for multiple types of aerosols (PAO-4, DOS/DESH...)

Suitable for different air conditioning system flow rates

Portable dust generation solution

3990-02 can emit high concentration aerosols ranging from 500 to 70000 cfm, with a heating time of less than 2 minutes. It is widely used for filter leakage testing in small air purification units to large clean room air conditioning purification systems. If conducting tests on FFUs, biosafety cabinets, clean workbenches, etc. in the cleanroom, it is recommended to use Laskin Nozle aerosol generators 3990-01 or 3990-03.

3990-02 high-efficiency leak detector generator for biosafety cabinetsTechnical Specifications

Flexible dust generation solution

Capable of producing industry standard polydisperse suspended particulate matter, and can adjust the concentration output according to actual needs to meet various application requirements. The 3990-02 series generator can be used in conjunction with the aerosol photometer 3990 to test the leakage of high-efficiency filters, facilitating the identification and quantification of leakage points for repair reference.

Durable design

3990-02 adopts a stainless steel shell, which will not deform due to excessive pressure and is easy to clean. Large capacity chamber, only needs to be adjusted to the appropriate temperature and pressure to work.

Nozzle connector

Optional nozzle connector can be used to direct high concentration dispersed suspended particles to a testing port located further away, ensuring no leakage.

2.4-inch true color display screen

Real time monitoring and display of internal gas path pressure and heating zone temperature, clear and accurate.
