Custom Air Shower Systems Available
Terra Universal offers custom fabrication to provide the optimal solution for your application.
Examples of requested modifications include:
- Custom floor plans, including 90º turns and U-shaped chambers (see examples below)
- 3-door configurations for connecting multiple rooms
- Custom flooring: stainless steel floor, no-floor, or raised aluminum floor grates
- Safety glass substituted for the SD-PVC panels on the doors
- Explosion-proof designs for safe operation near explosive or flammable materials
- Static ionization within the air shower enclosure
- Bumpers mounted on the interior walls to protect nozzles from carts
Motion Sensor
Air shower cycles are initiated by a motion sensor located on the ceiling of the chamber. If the LED lighting is set to Smart Lighting mode, the motion sensor will also turn on the lights when personnel enter the air shower.
Recirculation Vents
The closed-loop, recirculating design uses floor-level vents and plenums built into the walls to pull the contaminated air back through the HEPA filter, which removes 99.99% of particles as small as 0.3 microns.
LED Lighting
Low-profile LED lighting offers excellent visibility and power savings. Lights can either be manually controlled or set to automatic on/off via the touchscreen control panel.
Electromagnetic Interlock Door
Electromagnetic interlocking doors prevent personnel from accidentally opening both air shower doors at the same time, thereby preventing cross-contamination of the cleanroom and the external environment.
Emergency Exit Button
The emergency bypass button immediately shut down the air shower and release the doors when depressed; the doors also release when a power outage occurs to ensure operator safety.
Adjustable Air Shower Nozzles
Adjustable air nozzles on the walls and ceilings provide multi-directional flow of high-velocity, HEPA-filtered air to dislodge and remove particles from surfaces of personnel and parts before they enter the cleanroom.
Photohelic Gauge
The Photohelic gauge measures the backpressure generated on the dirty-side of the HEPA filter, providing an indication of filter saturation. With proper setup, the control panel will display an alert when the HEPA filter needs to be replaced.
Touchscreen Control Panel
The touchscreen panel controls cycle durations and entrance/exit delay times. Users can adjust these settings, as well as choose the operating mode for the LED lighting: always on; always off; or motion-detecting mode with shutoff-delay.
