As a professional manufacturer with over 20 years of experience (established in 1998), Anping County Boli Hardware Wiremesh Products Factory proudly presents our Automatic Sand Filter Vessel with 6m³/h Flow Rate and 0.5-1.2mm Quartz Sand Media. This high-quality filtration system is designed to deliver reliable, efficient, and low-maintenance solid-liquid separation for a wide range of water treatment applications. Our factory has exported to over 10 global markets including North America, Europe, and Southeast Asia, with annual export value exceeding US$5 million, ensuring you receive a product built to international standards.
Our automatic sand filter vessel utilizes a multi-port valve for fully automatic backwashing, eliminating manual operation and reducing downtime. The internal 0.5-1.2mm quartz sand media effectively captures suspended solids, particles, and turbidity, achieving filtration precision down to 20-50 microns. The vessel is constructed from high-strength carbon steel with anti-corrosion coating, guaranteeing long service life even in harsh environments. Key features include:
- Fully Automatic Operation – Programmable backwash cycle with adjustable timer or differential pressure trigger.
- High Flow Efficiency – Rated at 6 m³/h, suitable for medium-scale industrial, agricultural, or commercial water systems.
- Quartz Sand Media – Premium 0.5-1.2mm silica sand with uniform grain size for consistent filtration.
- Durable Construction – Welded carbon steel shell with epoxy-lined interior and external polyurethane paint.
- Easy Maintenance – Accessible top manhole for media inspection and replacement (optional).
- Customizable Options – Available in stainless steel (304/316), different flange sizes, and control valve brands.

The Automatic Sand Filter Vessel provides significant benefits to end users: reduced water waste (backwash only uses 2-3% of total flow), lower energy consumption (no electricity needed for filtration – only control valve), and consistent water quality even with fluctuating inlet turbidity. It is ideal for pre-treatment in reverse osmosis systems, cooling tower water, agricultural irrigation, and industrial process water. The 0.5-1.2mm quartz sand media offers a perfect balance between filtration efficiency and backwash ease, ensuring long media life (typically 3-5 years).

Frequently Asked Questions
Q1: What is the recommended backwash frequency for this filter?
A: The backwash cycle is programmable. Typically, for water with moderate turbidity, we recommend backwashing every 24-48 hours. A differential pressure switch (optional) can trigger backwash automatically when pressure drop exceeds 0.5 bar.
Q2: Can I use other filter media instead of quartz sand?
A: Yes, the vessel can accommodate different media such as activated carbon, manganese greensand, or multimedia layers. Please consult our sales team for specific media requirements.
Q3: What is the lifespan of the quartz sand media?
A: Under normal operating conditions, the 0.5-1.2mm quartz sand can last 3-5 years. It should be replaced when the sand becomes too fine or when backwash efficiency decreases.
Q4: Is the vessel suitable for seawater or high-chloride environments?
A: For corrosive environments, we recommend upgrading to stainless steel 316L or a heavy-duty epoxy coating. Please specify your water chemistry when ordering.
Q5: What is the maximum working pressure of this filter?
A: The standard design is 0.6 MPa (6 bar). We can supply vessels rated up to 1.0 MPa upon request. Always verify the rated pressure on the nameplate.
Q6: Do you provide installation and commissioning support?
A: Yes, we offer detailed installation manuals and online video support. For large orders, on-site commissioning can be arranged at additional cost.
Q7: What is the warranty period for this product?
A: We provide a standard 12-month warranty against manufacturing defects. Extended warranty options are available for an additional fee.
Q8: How is the vessel shipped? Is it assembled?
A: The vessel is shipped with the multi-port valve attached and the internal distributor pre-installed. The sand media is packed separately to avoid damage during transport. Simple assembly is required on site.
