The diluter has the characteristics of compact structure, light weight, and modular design

7.951 Mini Compressed Air Dilator VKL mini designed for use with all GRIMM aerosol spectrometers

Working together, the complete system includes a compressed air connection module and up to two dilution modules,

They have different inlet nozzles (1:10 and 1:31.6). Using the principle of an injector, aerosol samples are

Each dilution module is diluted with compressed air. Due to its modular design, the dilution ratio can be gradually adjusted

Select rows from 1:10 to 1:1000 (using two cascaded dilution modules). VKL mini diluter

It is a very flexible and compact dilution system with good working performance and compression

The advantage of low air consumption.

It is necessary to ensure the pressure of the undiluted sample airflow flowing into the diluter for accurate and reproducible sampling

The pressure of the diluted sample airflow leaving the diluter is equal, so do not operate under negative or overpressure conditions

Conduct sample sampling.

Easy to install and maintain

Installing and operating the 7.951 mini diluter VKL mini does not require any other tools. All connections are very

Easy to fix and loosen. This makes it easy to install and quickly replace different dilution ratios. Simply press down

Connect the compressed air to the dilution module, adjust the air pressure to 200mbar, and select the number of dilution modules

And the inlet nozzle, connect one end of the dilution module to the connection module of the diluter, and the other end to the aerosol solution

Gel spectrometer, all operations are like this.

The internal contamination of the diluter by particulate matter is easily detected and can be quickly cleaned. This ensures its

Good work performance, even under high concentration aerosol measurement conditions. The entire system, except for the connection modules

There are no other consumables besides high-performance surface filters used to generate compressed dilution air

Technical Specification

Aerosol input:0.6 liters/minute (1:31.6), 1.8 liters/minute (1:10)

Aerosol output: 1. 2 liters per minute

Compressed air input：Approximately 18 liters per minute (1:31.6), 18 liters per minute (1:10)）

Waste aerosol output: approximately 17.4 liters/minute (1:31.6), 18.6 liters/minute (1:10)

Temperature range: 0 to+40 ° C (32 to 104 ° F)

Pressure range: Pin=Pout (for such pressures, only a small amount of sampling is required!)

Humidity range: Relative humidity<95% (non condensing water droplets)

Calculation of dilution ratio

D = Qd/Q0 =dilution ratio

Qd = Q0 + Q1 =Diluted aerosol flow rate[rise/minute]

Q0 =Undiluted aerosol flow rate[rise/minute]

Q1 =Pure dilution air flow rate[rise/minute]
