Underdrains

1、Underdrains collects filtered water during filter operation and distributes air and water during the backwash cycle.

2、Excellent even distribution of air and water results in a longer pool.

3、the standard profile of B × L × H = 1000 × 300 × 330mm

4、Providing cleaner filters means longer filter run time and higher water efficiency, more product water and Fewer wastes. This can reduce operating costs per gallon or liter of filtered water.

5、made of HDPE for excellent strength and corrosion resistance. Flexible design, ideal for installations that require longer laterals.

6、can be equipped with media holder, up to 14 inches (36 cm) of gravel media holder can be replaced, so that in less vertical space or longer air / water backwash time to achieve the same media depth.

7、Air flow adjustability allows for more control and saves energy and water.

8、Uniform air-water distribution, which produces less waste water and reduces the operating cost of the filter.

9、It is applicable to new or existing older filter installation, and can be applied to a variety of filter pool types, with convenient, stable and low cost installation.
