STK2 Series Stainless Steel Filter Tank with Legs, Manhole & Sand Discharge (FRP Replacement)
STK2 Series Stainless Steel Filter Tank with Legs, Manhole & Sand Discharge (FRP Replacement)
The STK2 Series takes the durability of stainless steel and adds critical maintenance features lacking in standard FRP tanks. This model is equipped with robust Support Legs (Tripod), a Side Manhole for inspection, and a Bottom Sand Discharge Port. It offers the perfect balance of structural integrity and operational convenience for commercial and industrial water treatment.
- Structural Upgrade: Includes Manhole & Discharge Port for easy media handling.
- Mounting: Stable Stainless Steel Support Legs (Tripod style).
- Material: Corrosion-resistant SUS304 / SUS316L.
- Application: Ideal for Sand, Carbon, and Iron Removal filters.

Product Overview
The STK2 Series Mechanical Filter Tank is designed to overcome the limitations of traditional tanks. While standard FRP tanks often require disconnection and tipping over to change media, the STK2 Series incorporates industrial-grade features into a compact design. The addition of a Manhole and Sand Discharge Port significantly reduces maintenance downtime and labor costs.
Key Features & Benefits
- Easy Maintenance (Manhole): Equipped with a dedicated side manhole (or handhole depending on size), allowing operators to easily inspect internal distribution systems or top-off media without removing the control valve.
- Quick Media Replacement (Discharge Port): The bottom discharge port allows spent media (sand, carbon) to be drained out by gravity or water pressure, eliminating the difficult and messy process of extracting media from the top.
- Stable Support Legs: Unlike skirt bases that can trap moisture, the tripod leg design allows for easy cleaning underneath the tank and provides stable support on uneven floors.
- High Durability: Made from premium stainless steel, it is impervious to UV radiation and physical impact, ensuring a service life far exceeding plastic composite tanks.
Compatibility
Standard top openings (2.5" or 4") ensure compatibility with all major control valve brands (e.g., Runxin, Clack, Fleck), making retrofits seamless.
