The Professional Top-Mount Sand Filter is engineered to deliver industrial-grade performance for heavy-duty pool applications, combining robust construction with high-efficiency filtration. With flow rates up to 48 GPM, it is designed to handle the demands of large-scale pools and high-traffic commercial facilities. Its top-mount configuration simplifies media replacement and routine maintenance, while the reinforced FRP tank ensures exceptional durability even in harsh commercial environments. Equipped with a self-priming six-way valve, it integrates seamlessly with high-horsepower pumps (3–5 HP), making it a reliable choice for professional pool operators seeking consistent performance and minimal downtime.
Large Filtration Area: The Q1400 model features a generous 1.54 m² filtration surface, allowing continuous operation in high-traffic pools such as water parks and resort facilities. It removes 99% of particles ≥5 microns, including algae, bacteria, and fine sediment, ensuring pristine water quality.
High-Pressure Resistance: The tank is engineered to withstand 120 PSI internal pressure, making it compatible with commercial-grade pump systems that require higher flow rates to maintain water turnover in large pools.
Top-Loading Sand Chamber: The innovative top-loading design allows quick and easy sand replacement without the need to drain the entire filter or disconnect plumbing lines, reducing maintenance time by up to 60% compared to side-mount models.
Transparent Lid: A shatter-resistant polycarbonate lid provides a clear view of the sand bed condition during backwashing, enabling operators to visually confirm when the bed is clean and reducing unnecessary water waste.
Stainless Steel Clamp Ring: A heavy-duty 304 stainless steel clamp ring secures the lid to the tank, providing a watertight seal and resisting corrosion in chlorinated environments—critical for longevity in commercial settings with frequent chemical use.
UV-Stabilized FRP: The tank is constructed from UV-stabilized fiberglass-reinforced polymer that maintains structural integrity in direct sunlight for 15+ years, eliminating the need for frequent replacements in outdoor installations.
DE Grid Retrofit Kit: An optional DE grid upgrade converts the filter to a dual-media system (sand + DE), enhancing filtration precision to 1–3 microns—ideal for sensitive aquatic environments such as therapy pools or competitive swimming facilities.
Winterization Kit: Includes freeze-proof drain plugs, insulation sleeves, and a weather-resistant cover to protect the filter during cold months, ensuring reliable performance year-round in regions with freezing temperatures.
Commercial Pools: Perfect for Olympic-sized pools, water parks, and luxury resorts that require 48 GPM flow rates to maintain proper water circulation and filtration with high bather loads.
Municipal Facilities: Used in public pools, community centers, and aquaculture facilities where high water turnover rates (up to 6 hours) are required to meet health and safety regulations.
Heavy-Debris Environments: Excels in settings with high debris loads, such as golf course ponds, agricultural water treatment systems, and pools located near trees or construction sites.
High-Altitude Areas: Performs reliably in low-pressure environments (e.g., 5,000+ feet elevation) where standard filters may struggle with flow rates, thanks to its high-pressure tolerance and optimized hydraulics.
Q: What sand grade should I use?
A: For optimal balance between flow rate and filtration efficiency, use 0.45–0.55 mm quartz sand that meets ASTM C150 standards. Avoid using beach sand or overly fine sand, as they can cause pressure buildup or reduce flow.
Q: How long does a sand change take?
A: With the top-loading design, a complete sand change typically takes 30–45 minutes, including draining the old sand, cleaning the chamber, and adding new sand—significantly faster than side-mount filters, which can take 2–3 hours.
Q: Can it handle DE filtration?
A: Yes, with the optional DE grid retrofit kit, the filter can be converted to use diatomaceous earth, achieving 1–3 micron filtration for applications requiring ultra-clean water, such as competitive swimming pools or aquatic therapy centers.
Q: What is the maximum pool size?
A: The Q1400 model supports pools up to 100,000 gallons when paired with a properly sized 3–5 HP pump, ensuring adequate water turnover (at least once every 8 hours) for large commercial facilities.
