Welcome to Anping County Boli Hardware Wiremesh Products Factory – a professional manufacturer with over 25 years of experience (since 1998) in filtration and wire mesh solutions. Our Cooling Tower Water Pre-treatment Filter, 80μm Disc Type, Automatic Flush, 230V is engineered to protect your cooling tower system from suspended solids, algae, and debris, ensuring consistent water quality and reducing downtime. With annual exports of US$5–10 million and a global presence across North America, South America, Europe, Asia, Africa, and Oceania, we deliver reliable, cost-effective filtration solutions trusted by industries worldwide.
This automatic disc filter uses a stack of corrugated polypropylene discs to capture particles down to 80 microns. When the differential pressure reaches a preset level or a timer triggers, the flushing cycle automatically opens and backwashes the discs, removing trapped contaminants without interrupting the main flow. The 230V power supply ensures easy integration with standard industrial electrical systems, while the robust construction resists corrosion and chemical attack.
Key advantages of our disc filter include:
- High filtration precision – 80 micron absolute rating removes sand, silt, rust, and organic matter, preventing clogging in nozzles and heat exchangers.
- Automatic self-cleaning – reduces manual maintenance to almost zero; typical flushing cycle takes only 10–15 seconds and uses minimal water (1–2% of total flow).
- Low energy consumption – operates on 230V/50–60Hz, with power consumption under 50W during normal operation and slightly higher during flushing.
- Corrosion-resistant materials – main body made of engineering plastic (PP/PA) with optional stainless steel components for harsh environments.
- Compact design & easy installation – can be installed in-line vertically or horizontally, suitable for limited spaces.
- Versatile connection sizes – available from 2" to 4" flange or thread, with customizable adapters.

The disc filter is particularly beneficial for cooling tower systems because it:
- Prevents fouling of fill media, reducing scale and biological growth.
- Protects downstream equipment like pumps, chillers, and heat exchangers from abrasive particles.
- Minimizes water and chemical treatment costs by maintaining cleaner recirculating water.
- Extends the service life of cooling tower components, reducing replacement frequency.

Frequently Asked Questions (FAQ)
Q1: How often does the automatic flush occur?
A: The flush is triggered either by a preset time interval (e.g., every 2–8 hours) or when the differential pressure reaches 0.05 MPa (0.5 bar). The actual frequency depends on water quality. For typical cooling tower makeup water, flushing may happen every 4–6 hours.
Q2: What is the minimum water pressure required for operation?
A: The filter works with an inlet pressure of at least 0.2 MPa (2 bar). Lower pressure may affect flushing efficiency. We recommend 0.3–0.6 MPa for optimal performance.
Q3: Can this filter handle high flow rates for large cooling towers?
A: Yes, we offer multiple sizes. A single unit with 3" connection can handle up to 30 m³/h. For larger flow rates, we can provide parallel configurations or larger models. Please consult our technical team for sizing.
Q4: What maintenance is required besides the automatic flush?
A: The filter is low-maintenance. Periodically (every 3–6 months), inspect the discs for wear or damage and clean the manifold if needed. The automatic flush keeps the discs clean under normal operation.
Q5: Is the filter suitable for saltwater or brackish water?
A: The standard version uses corrosion-resistant plastic and stainless steel components. For high chloride environments, we recommend upgrading to all-stainless steel or duplex materials. Contact us for your specific application.
Q6: What is the warranty period?
A: We offer a 12-month warranty against manufacturing defects. Extended warranty is available upon request.
Q7: Can I get a customized voltage or connection?
A: Yes, we can customize the voltage (e.g., 110V, 380V) and connection types (threaded, flanged, grooved). Lead time and pricing will be confirmed based on your requirements.
Q8: How does the disc filter compare to a sand filter?
A: Disc filters offer higher filtration precision (80μm vs typical 50–100μm for sand), smaller footprint, lower backwash water consumption (1–2% vs 5–10%), and no media replacement. They are ideal for cooling tower pre-treatment where fine particle removal is critical.
