These Air Showers and Tunnels offer an effective way to remove surface-deposited particles from personnel—before they get to the cleanroom.

Enter the Cleanroom — and Leave Your Particles Behind!
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.

Clean, Durable Construction
Select models in any of three materials to suit your cleanroom requirements: white epoxy-finished 16-gauge cold rolled steel, 304 stainless steel, or particle board with a plastic laminate that seals all exposed edges.* All models feature anodized aluminum access doors with transparent plexiglass windows.

Customized Systems—on a Standard Basis The tables below provide ordering information on standard configurations of Air Showers and Air Tunnels. In addition to these, many other configurations are available to suit your application requirements. These include:
Custom Door Configurations: You may specify doors at many positions along an Air Shower or Tunnel, including a third door. Refer to the floor plans below. (Note: Three-door designs are not available for Air Showers less than 60" (1524 mm) in length.) HEPA Filtered Ceiling Air Shower: This option adds filter/blower modules mounted in the ceiling for enhanced particle control (functions most effectively with 6"(152 mm) raised floor; see description below). Typical air flow is 90 FPM (.46 m/s) (can be configured to meet individual specifications). Custom Floor Configurations: Any unit may be ordered either with no floor (for placement directly on existing floor), or with 6" (152 mm) raised aluminum floor grates (for improved air circulation, especially with the HEPA filter ceiling option).		Side Mount: Used where space restrictions do not allow use of standard 10-foot (3048 mm) high unit. In this configuration, the blower is mounted to the side of the shower chamber. Knock Down: When adding a shower to an existing cleanroom, the shower is broken down to wall and ceiling sections for field assembly. Safety Plate-Glass Doors: replace the standard plexiglass ones. Explosion-Proof Design: for safe operation with explosive or flammable materials. Static Ionized Grid: for safe, effective neutralization of static charges on personnel or equipment in the Air Shower/Tunnel.Bumpers: for protecting nozzles along the interior wall from carts.
