The personnel air showers from Weiber are specially designed antechambers that clean off dust particles, viable and non viable organic particles and other particulate matters from the clothes and skin surfaces of the personnel and equipments before they enter the clean room. They serve as an integral component of the modern clean rooms, providing a cost effective solution to the contamination problems. The fully automatic operation prevents the need for manual switching on/off of the air shower cycle and the shower time, providing an unmatched ease of use. The incorporated safety features such as magnetically operated interlocked doors, the auto reset feature and an array of alarms and LED indicators for actual and set parameters prevent accidental lockouts and ensure smooth functioning of the unit.
The programmable microprocessor based control offers an unparalleled application flexibility making the unit suitable even for highly stringent processes and extremely demanding applications. The use of pre-filters, HEPA filters and efficient fans and blowers ensures the continuous generation of high velocity air streams for scrubbing off surface-deposited particles from the personnel, whereas the recirculation of filtered air ensures highest level of sterility for particle sensitive processes. The electromagnetic interlocks allow only one door to be open at a time, therefore preventing cross contamination, whereas the emergency stop buttons located next to the doors allow either door to be opened, thereby preventing accidental entrapment of the personnel.
Our air showers allow programmable operation of the unit, unlike the conventional models and feature a pre-purge function for maintaining the sanctity of the clean air environment. These pre-tested and pre-wired units offer an ease of installation and are operational with a simple plug-in.

Operating Features
- Programmable operating mode and shower time
- The pre-purge function cleans the air shower interiors in the power-on mode
- Programmable pre-purge time from 0-3 minutes
- Microprocessor based controls for various set parameters and sequence of operation
- Floor matting operated switch for sequential operation of the air shower
- Fully washable pre-filters remove around 85% of particulate matters, therefore reducing the load on HEPA filters and increasing their efficiency and life span
- Highly efficient HEPA filters with around 99.99% filtration efficiency for removing particles as small as 0.3 microns and larger.
- Permanently lubricated direct drive centrifugal motors and efficient blowers for maintaining appropriate face velocities of the air (6000 ft./min + 20 feet), while producing minimum vibrations and noise level (less than 60 dB). Rated at 1/5 HP.
- Top mounted fluorescent lights concealed within the light panel provide a minimum illumination of 800 Lux
- Multidirectional air flow
- The air recirculation system boosts the air conditioning and filtration efficiency for reduced power costs
- Indicator lights on both sides of the air shower for regulation of traffic within the cubicle
- Door switch monitors open/closed doors
- LED indicators in the chamber indicate interlock and shower sequence
- Emergency buttons on both sides of the air shower immediately cut system power and unlock the door to prevent accidental lock-outs
- Interlocked and magnetically operated doors to prevent them from opening at the same time and during the pre-purge cycle
- The auto reset feature unlocks the doors to prevent accidental lockouts.
- The negative pressure models allow reversal of clean room/grey side settings, preventing the need for physical reorientation of the unit.
- An administrator PIN can be set to restrict access to air shower settings.
