Spain Ashley Sand Filter Pa licensing high-strength resin and glass fiber winding bonded. High strength, anti-aging, resistant to corrosion. Especially for sea water or chemical water treatment industry. Sand overall equipment portable canister, filter using ordinary quartz sand, and low cost. If the entire sand filter canister filter with biological material as can be at the same time as the biological filter effect. Sand filter tank internal use water distribution structure, easy to operate backwash. Modern aquarium engineering, pool engineering, aquaculture projects, sauna engineering, water treatment equipment industry sectors are very common. Features: 1. seamless casing reinforced polyester, glass fiber winding Sand spherical structure allows more robust, non-toxic surface after treatment 2. Anti-corrosion, anti-wear, anti-UV UV, anti-oxidation O3, sun, sea. Common freshwater flow. 3. Unique water distribution and water catchment formation balanced, high-culvert drainage system efficiency. 4. Filter high precision, good water quality, turbidity <20um. 5. high filtration velocity, filtration rate up to 10 ~ 50m3 / h / m2. 6. multi-directional valve operation easy and convenient, a transparent wash water outfall in order to observe the degree of clarity. 7. with a barometer, a manual vent valve and drain valve. 8. bolts, nuts and fasteners are made of stainless steel 9.
