STK1 Series Stainless Steel Mechanical Filter Tank with Skirt Base (FRP Replacement)
STK1 Series Stainless Steel Mechanical Filter Tank with Skirt Base (FRP Replacement)
The STK1 Series is a premium stainless steel mechanical filter vessel designed to replace traditional Glass Fiber Reinforced Plastic (FRP) tanks. Featuring a robust Skirt Base for standalone stability, this tank offers superior durability, UV resistance, and pressure handling compared to plastic alternatives. Ideal for multimedia filtration (Sand, Carbon, Resin).
- Material Upgrade: 100% SUS304 or SUS316L (No aging/cracking like FRP).
- Base Design: Integrated Stainless Steel Skirt Base.
- Compatibility: Standard thread openings (2.5" to 4") match common control valves.
- Application: Water softening, Sand filtration, Carbon adsorption.

Product Overview
The STK1 Stainless Steel Filter Tank (Skirt Type) is engineered for water treatment professionals who demand longevity and aesthetics. While maintaining the standard dimensions of FRP vessels for compatibility with control valves, the STK1 series eliminates the common issues associated with fiberglass tanks, such as UV degradation, fiber blooming, and cracking under pressure surges.
Why Choose Stainless Steel over FRP?
- Superior Durability: Stainless steel withstands physical impact, temperature fluctuations, and direct sunlight (UV) far better than FRP, making it suitable for both indoor and outdoor installation.
- Hygiene & Aesthetics: The polished stainless steel surface is easy to sanitize and offers a professional, high-end look that enhances the overall value of your water treatment skid.
- Skirt Base Stability: The welded skirt base provides a solid foundation, eliminating the need for separate tripod bases often required by smaller FRP tanks.
Media Compatibility
This vessel is designed to house various filtration media, including Quartz Sand, Activated Carbon, and Ion Exchange Resin. It is widely used in pre-treatment systems for RO, water softening, and industrial water purification.
