Stainless Steel Air Shower attached to BioSafe™ Cleanroom

Enter the Cleanroom and Leave Your Particles Behind!
Each unit is fully equipped with a protected passageway that allows a large number of personnel to pass into controlled areas without sacrificing convenience or cleanliness.

Air Showers and Tunnels supply concentrated Class 100 clean airflows to lift off contamination while an individual occupies the air enclosure. Whenever the shower cycle commences, pressurized air streams from adjustable nozzles at a velocity of up to 8,000 feet per minute (41 m/s). This ensures the necessary efficient scrubbing action to remove particulate matter.

Air nozzles are arranged on the 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 the vents and wall plenums of the Air Shower/Tunnel and back to the HEPA filter, which removes 99.99% of all particles as small as 0.3 microns.

Electromagnetic interlocking doors prevent unnecessary contamination inflow and thereby prevent cross-contamination of the cleanroom and the Air Shower/Tunnel. They automatically release in the event of a power failure or at the press of the emergency stop button to ensure operator safety. LED lighting, built into the ceiling to allow unimpeded air circulation, ensures full visibility no matter what size or configuration you select.

Touch-Screen Control Panel Enhances Convenience and Security.
Each unit includes a solid-state microprocessor panel (located at the front entrance) that controls shower cycle durations and entrance/exit delay times. A Run Times feature is also included to help you set and maintain a filter-replacement schedule based on your maintenance protocol.

This system includes full microprocessor diagnostic capabilities, covering operation of the blower, door switch, and door lock.

Clean, Durable Construction
Select models in one of two materials to suit your cleanroom requirements: white powder-coated steel or 304 stainless steel. All models feature anodized aluminum access doors with transparent SDPVC panels.

  1. The air nozzles for both unit categories (powder-coated steel and stainless steel) are fabricated of ABS plastic.
  2. The door frames on both unit categories (powder-coated steel and stainless steel) are constructed of aluminum with installed static-dissipative PVC panels for clear visibility, broad chemical resistance, and prevention of surface charge build-ups. Optional stainless steel doors are available for the Stainless Steel Air Shower/Tunnel units. Call Terra for a quotation.

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 (0.46 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), with 6" (152 mm) raised aluminum floor grates (for improved air circulation, especially with the HEPA filter ceiling option), or with a stainless steel floor (durable and easy to clean).
  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.

Filter/Blower Module Specifications
See ordering tables for type and number of modules installed in each Air Shower/Tunnel. All HEPA filters are rated 99.99% efficient @ 0.3 micron particles. All module motors use 3-phase power only. International voltages are available at no extra cost.
