Cleanroom Equipments Cleanroom Flooring System Air Filter

Air Shower is a self contained chambers installed at entrance to cleanroom and other controlled environments. It minimizes particulate matter entering or exiting the clean space. Personnel and materials entering or exiting the controlled environment are “Shower” by high velocity HEPA-filtered air jets with velocities of 20-25m/s . Contaminated air is then drawn through the part then filtered and recirculated.

CTS is a supplier in air showers for demanding applications in the micro-electronics, semiconductors, pharmaceutical, spray-painting, and food markets.

Cleanroom Applications: the greatest source of particulate contamination in a cleanroom is the operators. Air shower is installed between change room and the cleanroom. The air shower enhances cleanroom operating protocol by serving as a reminder to all operators that they are entering a controlled environment. Personnel therefore develop the habit of gowning up properly before entering the air shower.


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 into and out of the controlled environment.

Two-Way One-Way

Personnel may enter or exit the controlled environment through the air shower. When entering the controlled environment the shower is activated. When exiting the shower is disabled to reduce throughput time. The air shower program is able to detect if the person is entering or exiting the controlled environment via door sensors and a timesequenced control.


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.

Product Highlights
  • High velocity air jets nozzle in excess of 20 m/s ensure efficient scrubbing action to remove particulate matter.
  • The air shower is constructed of electro-galvanised steel sheets with an abrasion resistant oven-baked epoxy powder coated finish.
  • Mini-pleated HEPA filtration achieves > 99.99% typical efficiency at 0.3 micron particles.
  • A disposable pre-filter with 86% arrestance extends the life of the main filter.
  • Indicator lights mounted on both sides of the air shower exterior regulate traffic flow in and out of the cleanroom.
  • Permanently lubricated direct drive centrifugal blowers are used in conjunction with stainless steel air jet nozzles.
  • All electrical components are SIRIM approved / recognised.

The Clean Booth is a cost efficient alternative to a clean room. Cleanliness class 10 is achievable with this versatile equipment that is expandable, portable and durable. The framework offers a stable structure yet requires minimal construction time. The adjustable support allows for easy height adjustment.

The side panels can be constructed out of acrylic or anti-static vinyl sheet as per customer’s requirements. The High Efficiency Particulate Air (HEPA) filter ensures an efficiency of filtering 99.99% of 0.3μm or larger particles. The resulting laminar flow also restricts any contaminating particles present to the streamlines thus ensuring minimum contamination. For more stringent requirement, Ultra Low Penetration Air (ULPA) filter achieves a rate of 99.9999% of 0.12μm or larger particles .

CLEAN BOOTHS create a clean environment of a higher level of cleanliness within a clean room area.

It is complete with HEPA filter module mounted on ceiling structure for downward vertical clean air flow.

  • Easy installation and relocation
  • Capable of achieving Class 10 to Class 100,000 cleanliness
  • Frameworks can be epoxy finished steel, aluminum or stainless steel
  • Custom made size is available
