- Size:
- External size: Depending on the specific requirements, usually about 1400x1000x2050 mm or larger.
- Inner size: about 800x900x1900 mm or on demand.
- Material:
- Stainless steel (stainless steel) or powder coated steel (Powder-Cater Steel).
- Observatory windows are usually made from tempered glass.
- Door structure:
- Double doors with interlock lock systems to ensure that only one door can be opened at a time.
- Doors can be made from stainless steel or tempered glass.
- Air blowing system:
- Number of blowing hose: from 12 to 48 blowers (Nozzle) depending on the size and design.
- Wind speed: about 20-25 m/s (meters per second), ensuring enough force to remove dirt.
- Air angle of air: adjustable to ensure the airflow covering the entire surface.
- Air filtration system:
- HEPA (HEPA (High-Efficiency Particulate Air) is capable of filtering up to 99.99% of small dust particles to 0.3 micrometers.
- Pre-Filter filter to remove large particles, prolong the life of HEPA filter.
- Control and display:
- Electronic control panel with LCD/LED display displays information such as air bath, door status, and other parameters.
- Air bath time can be adjusted from 10 to 60 seconds or more.
- Pressure:
- Positive pressure inside the air bath room to prevent contamination from outside.
- Noise:
- Low noise level, usually below 65 dB to ensure the working environment is not affected.
- Power:
- 220V/50Hz or 380V/50Hz depending on the design and capacity of the air bath chamber.
- Additional options:
- UV lamp.
- Safety sensor to disconnect when the door is open or have people in the chamber.
