We are a leading manufacturers of air showers for clean rooms based at hyderabad , India.
Each unit is a fully equipped, protected passageway that allows large numbers of personnel to pass into controlled areas without sacrificing convenience or cleanliness.
Air Showers and Tunnels supply concentrated Class 100, clean air flows to lift off contamination while an individual stands in, or walks through, a specially constructed air chamber. Whenever an automatic floor switch inside the unit is activated, pressurized air streams from adjustable nozzles* at a velocity between 6,000 and 8,000 feet per minute (30 m/s and 41 m/s), a force that ensures efficient scrubbing action necessary to remove particulate matter. (Air showers in units without floors are activated by motion sensors.)
Nozzles* are arranged on walls and ceilings in a uniform pattern to ensure effective distribution of filtered air; the lowest nozzle is positioned 19" (483 mm) off the floor. The closed-loop circulation design directs contaminated air downward through grills and hollow walls of the Air Shower and back to the filter, which removes 99.97% of all particles as small as 0.3 microns.
Interlocking doors prevent unnecessary contamination inflow and thereby prevent cross-contamination of the cleanroom and the Air Shower or Tunnel. They automatically release in the event of a power failure to ensure operator safety. Fluorescent lighting, built into the ceiling to allow unimpeded air circulation, ensures full visibility no matter what size or configuration you select. In addition, an emergency stop button on each Air Shower/Tunnel sounds an alarm and releases the door lock for exiting.
Control Panel Enhances Convenience and Security
Each unit includes a solid-state microprocessor panel (located at the front entrance) that provides complete control over access to the Air Shower/Tunnel (and hence to the cleanroom itself).
It includes a light switch, and audible alarm and alarm reset, and a 4-line, 64-character alpha-numeric LCD display that monitors system function during normal operation and displays menu functions for service and system changes. A 16-key membrane keypad allows a user to turn the system on and off (with a 4-digit code), to get into systems set-up mode (with a 4-digit code), and to program such information as a system clock, cycle time, access door delay, time lock feature, and single-direction access code. These capabilities let you program as much security into your system as you require!
This system also includes full microprocessor diagnostic capabilities, covering operation of the blower, door switch, door lock, and presence sensor/mat switch.
