Featured with precision machining and consistent slots, Filson slotted PVC well screen is designed with a larger intake capacity and higher clog resistance performance by reducing entrance velocity. With a low possibility of solids being carried in, it greatly improves the production of wells.
Thanks to its robust construction, Filson prepacked well screen is durable and reliable. Compared to gravel pack well screen, it is an ideal solution for various wells in unconsolidated formations as its more economical and convenient.
PVC Well Screen Types by Application (3)
Adopting high-level PVC as base materials, Filson PVC water well screen is non-toxic, which means it is not change the taste, odor and color of water, or releases any harmful substances into water. With high resistance to bacteria, it is completely safe during operating.
With enhanced mechanical strength and stable performance, Filson PVC monitoring well screen has excellent resistance to collapse and corrosion, which prolongs its lifespan and saves maintain costs. Due to lightweight and various connection types, it is also installed easily.
Filson PVC well casing pipe is fully impervious to corrosion and chemicals, hence it can withstand critical environment in well. Besides, it is also featured with lightweight, so it is easy to handle, install and transport. With longer service life.
PVC Well Screen Types by Diameters (5)
With advanced manufacturing process, Filson 10-slot PVC well screen enjoys smooth slot spacing that minimizes the possibility of encrustation and clogging. What’s more, it can realize larger open area and higher efficiencies with at fraction of cost.
Through delicate machined, Filson 1-1/4 PVC well screen enjoys precision dimensions. Equipped with smooth and flat slot openings, it achieves minimal drawdown and low energy consumption, while protect sensitive equipment by resisting clogging or plugging.
After sophisticated design and precisely engineered, Filson 2inch PVC well screen is endowed with uniform and smooth slots, which reduces the tendency of sediment building up and plus the open area. With high quality, it improves the efficiency and productivity of well.
Filson 4inch PVC well screen plays an important part in increasing well efficiency and longevity, as its clean slots steady water flow and keep sediment out of the well system. With various connection types, it can be installed and handle fast and easily.
Thanks to it completely immune to corrosion, Filson 6inch PVC well screen is not easy to rust as metal well screen. Therefore, it has outstanding robust and durable properties to withstand harsh conditions like high temperature and high corrosion environment.
PVC Well Screen Benefits
Mainly formed by high-level polyvinyl chloride, Filson PVC well screen is endowed with superior mechanical strength, and more durable to last long service life.
With a lighter weight than a metal well screen, Filson PVC well screen is easier to install and handle with less labor costs.
Equipped with smooth and uniform slots, Filson PVC well screen effectively prevents sand and encrustation, while saving energy.
Filson PVC well screen is available in various sizes, diameters, and lengths based on customers’ applications.

PVC Well Screen FAQ Guide
The best PVC well screen needs to satisfy some design criteria and functional standards. There are as following:
- A large open area
- Clog-free slot openings
- High corrosion resistance
- Collapse resistance and sturdy structure
- Easy to install and handle
- Low possibility of sediment building up
- Outstanding sand control property
There are three types of wells: bored or shallow wells, consolidated wells, and unconsolidated wells. Each one enjoys unique characteristics.
- Bored/Shallow wells: usually 100 feet deep or less
- Consolidated Wells: usually 250 to 30 feet and in the natural rock formation
- Unconsolidated wells: mainly formed by soil, clay, sand, and other easily collapsible materials.
Casing: to prevent collapse the most common casings are PVC pipe, galvanized steel, etc.
Grout: a sealant to fill the gaps around the well, in order to protect wells from contaminants, and it is usually made of cement, concrete.
Well screen: a filtration to block gravel and sand while allowing the passage of water, and the most and popular material is PVC.
Gravel pack: around the well screen to help further filtration while adding stability to the well.
Depending on different materials, the service life is also different. Such as carbon steel well screens can last almost 25 years, and PVC types can last up to 70 years.
The proper well screen size is a significant step to improve the productivity of the well. First, the right velocity should not exceed 1/10 of a foot per second. The proper velocity can be calculated by dividing the GPM of the well yield by the open area.
The proper slot size is designed upon the formation of samples. Filson offers services like sand analysis of formation materials, which may help you a lot.
