To properly size and select the filter for a pool or spa you must first calculate the pool s volume and capacity.
Pool filter capacity.
There you have it.
Water is not filled all the way to the wall or deck line which is why pool capacity is a lower number than pool volume.
It is always recommended to oversize the pool filter.
Pool capacity is defined as the number of gallons of water that a pool can hold.
This nsf listed filter comes with a massive filter area for enhanced capacity with 1 5inch 100 drain clean out port.
Pool capacity in gallons divided by the desired turnover rate in hours.
Comes with a high flow internal air relief as well as manual air relief valve.
A filter fits into the equipment sequence after the pump so whether you re replacing an old filter or installing a filter on a newly built pool you ll need to match the filter to the pump and the size of the pool.
Instant action thanks to an effective filtration area of about 420 square feet and a flow rate of 150 gallons per minute.
This will give you the minimum flow needed in gal m gallons per minute.
Selecting the right one requires consideration of.
Pool volume is the spatial measurement of a pool.
Therefore your goal is to determine which model of filter can handle 62 3 gallons of water per minute resulting in the desired complete turnover every eight hours.
An undersized filter can lead to numerous problems including cloudy pool water increased chemical demands ph swings and unsafe swimming pool water.
The advantage when compared to other pool filter pumps is the exceptionally fine filtration offered by de filtration it captures particles as small as 2 microns much smaller than the width of a human hair which is about 50 microns.
In our inground pool example we need a pool pump with a 20 8 43 gpm flow rate range and 50 tdh also called feet of head.
Each pool filter media has its own unique advantages and disadvantages.
De pool filter pumps use a filtration grid coated with diatomaceous earth de.
Okay we now have everything we need.
All pool pump models will have charts with horsepower estimates based on flow rate ranges and total dynamic head.
The calculations for your 29 920 gallon pool show that you require a flow rate of 62 3 gpm to filter the pool s capacity in eight hours.
Find a pump that meets the gal m you just calculated.
Adequate filtration is the primary source of clean clear pool water.
Vl series sand filter and pump systems offer the performance and reliability expected from the world s leading provider of above ground equipment.
Divide this number by 60 to get the gal m.
Stating this situation another way.
The equation used in calculating filter sizes is.
