HEPA filtered Air Showers
Telstar HEPA filtered air showers are specially designed to remove particulate matter from the clothing of personnel entering
and exiting containment areas.
Within the enclosure of the air shower, particles are removed from clothing or materials being transferred by high-speed jets of
air.
In order to increase the output and efficiency of the air shower, the airspeed is sufficiently high to remove particles by kinetic
action. In addition, an extremely low particle level is achieved by means of filtration before the air enters the chamber.
Design Features
•Module fabricated internally and externally in stainless
steel AISI 304.
•Stainless steel doors with double-glass windows and
electromagnetic interlocks.
•Electronic programmer to regulate the dwell time within
the shower.

passage without performing a cycle.
•EC fans that provide reduced energy consumption (Green
Technology).
•Pre-filter positioned for easy access and maintenance.
•HEPA filters positioned in the top of the unit.
•Differential manometer to indicate the level of HEPA filter
particulate burden.
•Operation time counter.
•Time clock.
•Doors with perimeter joint around four edges and
electromagnetic interlock system.
•Emergency Pushbutton placed in a low level into the
shower.
•Floor reinforced with a sheet of stainless steel AISI 304,
with step in the entrance and exit.

Operating Principle
The shower operates when it detects the access door
opening and closing or when it detects the presence of a
person or object in the correct position. During operation,
the doors are interlocked to prevent personnel exiting the
shower before completion of the decontamination cycle.
There is an emergency push-button, which halts operation
and opens the doors. For use in highly critical areas it is
possible to set the emergency stop system to permit exit in
one direction only.
