Air Shower Int AHU
  High performance - low energy
PBSC’s personnel air shower comes in two designs, one with the
integrated Air Handling Unit (AHU) on the top of the shower or with a separate AHU which has “Safe Change” filters.  Both are designed to remove particles from the operative with high velocity jets of air.  This web page is on the integrated design which is designed to remove non-hazardous particles on the entry to a controlled area.  Please see our other air shower information if the particles are hazardous and a safe change on the filter housing is required.

The air shower is the latest design which has been continually improved over the years and features either a stainless steel or powder coated steel construction with interlocked float/toughened glass personnel doors. The shower has final assembly in place and requires no cranes or special access on site as the largest piece will fit through a single door way.

Maximum clear opening, the door design has been refined to provide a maximum clear entry width with the frame  finishing flush to the internal panels.  (straight through design only). 

There are 9 x adjustable stainless steel nozzles on each of the two side walls in the shower, total of 18 nozzles in the shower.

As the operative enters the shower the PLC automatically turns on the high performance 24VDC LED light which is powered from the PLC (no mains power in the shower cubicle).

The design of the shower has the lowest nozzle only 21.5cm from the finish floor level and a low level return on each wall panel to the AHU built into the top of the shower cubicle.

When the shower cycle is started by the operative, the shower controls lock the doors and run the fans to provide the air flow below.  Note the shower has a low power usage with highly efficient fan, the total power requirement is only 10Amps @ 110 – 230V, 50 to 60HZ, 1 Ph.

Clean Filter – 150 Pa

32m/s at 5cm from the nozzles

Dirty Filter – 300 Pa

28 m/s at 5cm from the nozzles

The system is available with a range of control panel options, the standard is a Siemens Logo, but it can be provided with an Allen Bradley PLC or a Siemens S1200 PLC. 

The S1200 PLC comes with a touch screen in the shower (or on the PLC cabinet) to show the shower status, alarms can be seen and cleared from the screen.
