Cleanroom Air Shower and Tunnel Manufacturer

• High-velocity air jets

  High-velocity shower jets running at 18-30 m/s to ensure efficient scrubbing action to remove particulate matter

• Stainless steel nozzles

  Permanently lubricated direct drive centrifugal blowers used in conjunction with stainless steel air nozzles

• Programmable operation

  Operating modes can be programmed in the field

• Operating modes can be programmed in the field

  Microprocessor controller supervises all functions

• HEPA or ULPA filtration

  Filter efficiency of H14 HEPA filter(s) is 99.9995% at 0.3 micron particles, while ULPA filter(s) provide 99.9999% typical efficiency for particle sizes of 0.1 to 0.3 microns.

• Pre-filtration

  A disposable prefilter with 85% arrestance extends the life of the main filter.

• Emergency buttons

  An emergency stop button is mounted on both sides of the shower

• Indicator lights to signal door status

  Indicator lights mounted on both sides of the exterior of the air shower to regulate traffic flow, in and out of the cleanroom.

• Durable doors

  Heavy-duty, durable doors with glass windows to permit visibility.

• Powder-coated steel construction

  The air shower is constructed of electrogalvanized steel sheets with an abrasion-resistant oven-baked powder coated finish. (Optional: Stainless steel 304 construction)

• Uniform lighting

  Light diffusers ensure uniform lighting throughout the chamber

• Air is forced by the blower(s) through ULPA filter(s) which are 99.9995% efficient against particles of 0.3 microns.
• Filtered air is ejected through nozzles at high velocities into the chamber. These turbulent air streams disperse particulate matter on all surfaces.
• Dispersed particulate matter migrate with the air stream towards the lower areas in the air shower chamber. Air enters the blower supply plenum through pre-filter(s) installed at the base of the chamber.
• The air is continuously filtered and recirculated. The air shower is a self-contained device and does not exchange air with the environment it is placed in.

Unlike conventional air showers which are delivered with a fixed operating sequence, the Airomax Cleanroom Air Shower’s operating sequence may be selected from three pre-programmed sequences:

1. One-Way
   (Left Illustration): Personnel may enter the controlled environment but not exit through the air shower. At the idle state, the clean side door is locked while the grey side is unlocked. This mode of operation is useful for controlling traffic patterns in and out of the controlled environment.


2. Two-Way One-Way
   (Middle Illustration): Personnel may enter or exit the controlled environment through the air shower. The air shower program is able to detect if the person is entering or exiting the controlled environment via door sensors and a time-sequenced control.


3. Two-Way
   (Right Illustration): Personnel may enter or exit the controlled environment through the air shower. In both directions, the air shower is activated. This mode of operation is useful in pharmaceutical and lab animal research applications to prevent the egress of hazardous substances and allergens from the controlled environment.

1. What are the benefits of integrating cleanroom air showers in controlled environments/ facilities?
   

   Installation of Airomax cleanroom air showers enables seamless entry/exit of personnel in and out of the controlled environment. The “scrubbing” effect of the high-velocity air showers on particulate matters or surface contaminants allows mitigation of potential cross-contamination; thereby increasing cleanroom and process integrity.

2. What is the initial air velocity of Airomax cleanroom air showers?
   

   Initial air velocity of Airomax Air Shower is 18-30 m/s (3543-5906 fpm).

3. What is the diameter of the air shower nozzles provided for Air Shower?
   

   Air nozzles of Air Shower are adjustable, constructed with stainless steel, and are 25mm (1") in diameter.

4. What is the typical efficiency of filter/s used for Airomax cleanroom air showers?
   

   Filter efficiency of H14 HEPA filter(s) is 99.9995% at 0.3 micron particles, while ULPA filter(s) provide 99.9999% typical efficiency for particle sizes of 0.1 to 0.3 microns.

5. Can Airomax cleanroom air showers measure the differential pressure across filter?
   

   Standard models of Air Shower are not designed with a device to measure and display differential pressure across filter. Upon client request, Airomax can customize cleanroom air showers to have add-on magnehelic gauges to display differential pressure value across filters.

6. How are Airomax cleanroom air showers shipped?
   

   Depending on client request and dimensions of ordered air shower, Air Shower can be shipped in assembled, module or unassembled form.
