pureliQ:A – the automatic backwash filter

The automatic filter pureliQ:A is designed for the filtration of drinking and industrial water.
Convenient filtration thanks to the automatic filter pureliQ:A.
A motor unit automatically takes care of the time-controlled backwash for you.  
pureliQ:A: It couldn’t be more convenient.
The automatic filter pureliQ:A is perfectly suited for all fields of application. For every pureliQ filter is developed with due diligence and tailored to the prevailing needs - designed for today's as well as for future requirements.
The filters can be used for positive pressure and negative pressure applications. A backwash and the adjustment of the after-pressure on the withdrawal side, however, are only possible when applied in the positive pressure range.
The automatic filter pureliQ:A is designed according to the stipulations of DIN EN 13443-1 and DIN 19628 and intended for the installation in the drinking water pipe according to DIN EN 806-2 (installation immediately downstream of the water meter).
It protects the water pipes and connected water-carrying system parts from disturbances and corrosion damage due to undissolved impurities (particles) such as rust particles or sand. The unfiltered drinking water flows into the filter from the inlet side and then from the outside in through the filter element and to the pure water outlet. Thus, foreign particles > 100 µm in size are retained. Depending on their size and weight, the foreign particles either stick to the filter element or they fall straight down into the filter cylinder. The controller automatically releases the backwash as per the setting. Possible settings for the backwash intervals are 7, 30, 60 and 90 days. A manual backwash can be released at any time, however.
