Manufacturer: Testing - Slovenia / Origin: Slovenia
A dust chamber is a type of environmental testing equipment that is used to simulate dust and particle ingress on products and equipment. The chamber is designed to comply with international standards such as IP5X and IP6X, which specify the degree of protection provided against the entry of dust and other particles.
Specifications:
| Model: T1-15 |
| Inner dimensions WxDxH 800x800x900 mm ~ 576 L |
| Test cabinet is equipped with sealed lockable glass door with wiper, inside grid and consoles for sample mounting, entry port for possible sample supplying on the left wall, light and vacuum connection on the right wall. |
| Below the sample carrying grid is the funnel with a vibrator, which prevents excessive dust depositing on the walls and protective wire mesh on the hinge, |
| On the bottom of the funnel is dust circulation turbine, which together with the vibrator assures suspension of dust in the test cabinet. |
| On the bottom of the funnel is also located heater with thermostat for drying the dust. |
| Besides the dust circulation turbine there is also depression turbine, which draws the air out of the sample during the IP6X tests. |
| Both turbines have brushless motors with magnets, electronic control and protection, which ensures their durable operation. |
| The air is drawn out of the sample, through vacuum connection on the wall, through the filter, digital depression meter, that is needed to control max. allowable depression in the sample and through air flow totalizer, that measures the quantity of air drawn through the sample, as requested in the standard. |
| The control box on the frontplate are located all elements for controlling the operation of the chamber: |
| Depression turbine switch and potentiometer, by which the requested depression of 20 mBAR can be adjusted (if the sample allows it) |
| Switch and potentiometer for control of dust circulation turbine, |
| Switches for heater and light control |
| Push button for additional manual triggering of vibrator |
| Timer for automatic on/off switching of chamber |
| Line voltage U = 220V, 50 Hz |
| Power consumption max. 2400 VA |
| Heater 150 W |
| Depression turbine 1100 VA |
| Dust circulation turbine 1100 VA |
| Air flow totalizer 0,06 – 10 m3/h; ±3%(0.06-0.12 m3/h); ±2% (0.12-10 m3/h) |
| Depression sensor 0-50 mbar = 4-20 mA, max. permissible 200 mbar |
| Timer 24 h, min. interval 15 min. |
The chamber consists of a sealed enclosure with a viewing window, and a rotating sample holder. The sample holder can be loaded with test specimens, which are then rotated continuously within the chamber while dust is introduced into the chamber.
The dust chamber is designed to create an environment where dust particles of a specified size and concentration are present in the air. The test specimens are exposed to this environment for a specified duration, during which their level of protection against dust ingress is evaluated.
The chamber is typically equipped with a dust feeder that can generate dust particles of various sizes and concentrations. The dust is fed into the chamber using an air flow system that is designed to create a uniform distribution of dust particles within the chamber.
The dust chamber is commonly used in industries such as automotive, electronics, and defense to evaluate the effectiveness of products and equipment in resisting dust ingress. The test results can be used to improve product design and development, ensure compliance with industry standards, and ensure the reliability and durability of products and equipment in harsh environments.
