Scan Kleen Filters
Quick and easy manual cleaning. Scan-Kleen Screen Filters offer quick and easy manual cleaning without flow interruption. To clean, just open the flush valve and turn the handle to rotate the dirt collector. The combination of rotation and linear movement scans and cleans the whole internal screen surface. Water flow is not interrupted during the cleaning process. A stainless steel screen provides strength and long life durability.
Quick And Easy Manual Cleaning
The stainless steel screen provides strength and long life durability and is ideal for use as a primary filter on well water with small amounts of sand or reservoir water with small amounts of algae. When cleaning the filter, there is no need to manually disassemble, clean the screen and reassemble the filter. Just open the flush valve and turn the handle to rotate the dirt collector. The combination of rotation and linear movement scans and cleans the while internal screen surface. Water flow is not interrupted during the cleaning process
Product Advantages
- Corrosion-proof high density polypropylene will not rust or corrode like metal filters.
- Operates efficiently at varied flow rates.
Applications
- Primary filter on well water with small amounts of sand
- Primary filter for center pivots
- Reservoir water with small amounts of algae
- Back-up filter for:
- Media filter batteries
- Sand separators
Filtration Operation
Water enters the filter through the inlet and reaches the screen (1) which traps the particles from the water. As more water flows through, debris builds up on the screen. As debris accumulates on the screen, a pressure differential builds up between the internal and external sections of the screen.
Flushing Operation
When the pressure differential reaches the determined value (7-10 psi), the filter should be cleaned. Water continues to flow through the filter during the cleaning process.
- Opening the flushing valve (4) allows water to flow out of the filter
- Suction occurs through the nozzles (6) which vacuums the debris from the screen (1) and out the drain port
- Turning the handle (3) slowly rotates the dirt collector (2) resulting in full scanning of the screen by the nozzles. Slower rotation cleans the screen more efficiently.
This combination of rotation and linear movement cleans the whole internal screen surface. The flushing cycle takes about 10 seconds.

INFORMATION QUESTIONS
FREQUENTLY ASKED QUESTIONS
What is Hydroponics?
Hydroponics is the science of growing plants without soil. The plants thrive on the nutrient-water solution alone. The growing medium merely acts as a support for the plants and their root systems while the solution passes freely. The growing medium, if any, is totally inert.
What types of plants grow best hydroponically?
Anything can be grown hydroponically, but some plants prove to be more space efficient. Some plants we suggest are tomatoes, sweet peppers, hot chilies, lettuce, spinach, squash, cucumbers, broccoli, beans, snow peas, herbs and flowers of all types.
Can you REALLY get better yields/quicker growth?
Absolutely. The plants, when receiving everything they need, tend to be healthier, faster growing and generally more productive. You can expect 30% faster growth with many crops.
What are the watering cycle timelines hydroponic systems?
Once the reservoir is filled with nutrients, it is time to put your hydro system to work! The ease of hydroponics is automation – automation is achieved by putting the pump on a timer according to your watering needs. The watering cycle depends on growth stage, growing medium and hydroponic system. In an ebb and flow or drip system with rockwool as the medium, seedlings, clones and plants in the early vegetative stage require watering only once a day for 15-30 minutes (twice a day for higher temps). Mature, flowering and fruiting plants require a heavier feed and can be fed once a day for 30 minutes (twice a day for higher temps). Typically soiless mixes and coco fiber can be watered for about 15 minutes twice a day, and can be adjusted for heavier feeding during the flowering and fruiting stage or higher temps. ViaStone, Hydroton, Grow Rocks, and Silicate mediums need to be watered more frequently – a constant drip for drip systems, and about 15-30 minutes every 3 hours for ebb and flow systems and can be adjusted for heavier feeding during the flowering and fruiting stage or higher temps. Aeroponic systems require frequent watering cycles; 30-60 seconds every few minutes or a constant spray.
What do I need to test pH? How do I test pH?
pH has a range from 0 (acidic) – 14 (alkaline), with 7 being neutral. A proper hydroponic pH range is between 5.5 to 6.2 for most hydroponic crops. For specific crop pH, check out our Plant Guide. pH must remain within the proper range for good plant health, disease resistance, and proper nutrient uptake. pH is maintained by adding pH Up and pH Down to the nutrient solution. For more information, see the Testssection of our site.
How will the flavor compare to my outdoor grown, organic produce?
The taste may be even better! This is simply due to the fact that the hydroponically grown plants are getting everything they need, when they need it. Don’t be fooled by “hot house” produce grown commercially. The grower’s primary concern is shipability and storage, not flavor. When you grow your own vegetables at home, you can expect nothing less than excellent results. Plus, hydroponically grown produce has the added benefit of a longer shelf life.
