SECTION I INTRODUCTION
1.1 Description
The OBF series features automatic, self-cleaning screen type water filters.
The filtration system consists of a tank body with a first stage mesh screen
and a second stage fine screen, a 2" flushing valve and an electronic
controller. (See OBF Design Specifications, pages 23 and 24)
1.2 Theory of Operation (see Page 16)
Pressurized water enters the filter inlet and travels through a 1/8" perforated
stainless steel coarse screen where large particles are pre-filtered. The water
then passes through a fine stainless steel screen where small contaminants
(down to 10 microns) are filtered out. The clean water then exits the outlet.
When the fine screen becomes contaminated, a pressure differential is
sensed causing the automatic controller to open the flushing valve. When
the flushing valve opens, the pressure is reduced causing the clean water
to reverse flow through the filter element pushing contaminants off the screen,
through the nozzles, through the water motor and out the flush valve.
The water passing through the angular holes in the motor creates a torsional
rotation of the nozzles, thus vacuuming the entire I.D. of the filter element.
When the screen is clean, the unit automatically returns to the full filtering
mode.
The entire cleaning cycle takes approximately four to six seconds and uses
10 to 12 gallons of water. It should be noted that even during the backflush
cycle, the filtration process continues uninterrupted.
1.3 Recommended Applications
Tekleen OBF water filters are ideal for filtering out silt, scale, sand, rust, dirt
and organic material like algae, zebra muscles, and clams from virtually all
types of water sources.
