WIKA LTD500 Dirt Trap

The WIKA LTD500 dirt trap is specifically designed to protect the WIKA CPH7600 Wally Box III pressure calibrator from contamination. Soiling of the integrated pump, for example, through contaminated test items, can lead to faults on the pump or require the pump to be cleaned.

The dirt trap is attached, hand-tight, at the pressure connection of the calibrator. Sealing is achieved via the O-ring fitted on the ⅛ NPT male thread of the dirt trap. The maximum working pressure is limited to 35 bar.

The test item is mounted to the upper connection of the dirt trap, using a suitable sealing method. The connection to the test item is usable universally as 1/8 NPT female or 1/8 BSP female. Use a 1/8" or 23 mm wrench on the hex of the upper pressure port to connect the test item with the dirt trap. As soon as either moisture or dirt can be seen in the transparent chamber, the dirt trap should be removed and cleaned. Once the upper dirt trap connection has been unscrewed, the transparent acrylic chamber and the O-rings can be removed and cleaned with a clean cloth.
