Clean Room Air Shower Tunnel

Air Shower Tunnel 

Accumax India Air Showers are self-contained chambers installed strategically at entrances to cleanrooms and other controlled environments. They minimize particulate matter entering or exiting the clean space to mitigate the risk for cross-contamination.Personnel and materials entering or exiting the controlled environment are “scrubbed” with ULPA-filtered air by high-velocity air jets running at 18-30 m/s (3543-5906 fpm). Contaminated air is then drawn through the base within the unit, filtered and recirculated.

Accumax India is the pioneering company for the manufacturing and construction of cleanroom air showers with
Different applications in the following areas:
  • micro-electronics
  • semiconductors
  • pharmaceutical
  • Spray Painting
With greater than 25 years of experience in the industry, Accumax India is consistently manufacturing, and supplying reliable air showers and clean air solutions to reduce the potential for cross-contamination, and enhance cleanroom integrity.


  • 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.

  • 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.

  • Powder coated steel construction

       The air shower is constructed of electrogalvanized steel sheets with an abrasion-resistant oven-baked powder coated finish.


  • 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.

Operating Sequence
Unlike conventional air showers which are delivered with a fixed operating sequence,Accumax India 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.

  • Air showers provide cost-effective contamination control technology

How much does an Air shower cost

The cost of an Air shower would depend on the number of persons taking shower in one go.As a leading Air Shower manufacturers,Accumax India manufactures Air Shower according to the need of customer.Get Air Shower price and technical specifications from Accumax India.

Frequently Asked Questions


1. What material is Air Shower?

Accumax India manufacture Air Showers constructed of Stainless Steel.


2. What is the size of an Air Shower?

 The standard size of an Air Shower is 900x1000x2000 mm (Inner Area) and 1400x1075x2150 mm (Outer Area)


3. What is the cycle of an Air Shower?

This is one of the important aspect of an Air Shower effectiveness.Studies suggested that 20-30 seconds of Air Shower is effective to remove contimantion 


4.What is the nozzle velocity of an air shower?

To specify the most effective air shower, look for one that produces nozzle velocities of 7,800 feet per minute (fpm) and circulates 1,900 cubic feet per minute (cfm) of air. Velocity is measured at the nozzle, and cleaning effectiveness deteriorates as distance from the nozzle increases.


5.What are the different types of air showers?

Common geometries or types of air showers include: cart, single door, straight, tunnel, L-shaped, S-shaped, U-shaped and three-door air showers.


6. What are the advantages of integrating cleanroom air showers in controlled environments/ facilities?

Installation of Accumax India 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.
7. Can Accumax India 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, Accumax India can customize cleanroom air showers to have add-on magnahelic gauges to display differential pressure value across filters.

8.How are Accumax India cleanroom air showers shipped?

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