Its body is high-strength, chemical-resistant thermoplastic, built for harsh conditions and long-term outdoor installation, with a built-in anchoring base. The range suits hotels, leisure facilities, residential developments and aquatic centres. It delivers high flow with efficient filtration and minimal maintenance, and the datasheet says it gives consistent, crystal-clear water throughout the filter's service life. ## Key features - Three vessel sizes: 600, 750 and 900 mm - Up to 240, 350 and 500 L/min - High-strength, chemical-resistant thermoplastic body - Top- or side-mount multiport valve, six modes - Integrated pressure gauge and manual air bleeder - Silica sand media ## Specifications | Item | Value | | --- | --- | | Model code | AQS-600-900 | | Type | Sand media filter | | Vessel sizes | 600 · 750 · 900 mm | | Flow · 600 | Up to 240 L/min | | Flow · 750 | Up to 350 L/min | | Flow · 900 | Up to 500 L/min | | System range | About 30,000 to 240,000 L | | Body | Chemical-resistant thermoplastic | | Media | Silica sand (specify on order) | | Valve | Top- or side-mount multiport, 1½″ · 2″ · 2½″ | | Fitted | Pressure gauge · manual air bleeder valve | ## Who AquaShield is for - Hotels and leisure facilities that need high-flow water clarity. - Residential developments with shared water features or systems. - Aquatic centres: the 900 mm vessel handles up to 500 L/min. - Sites with systems of roughly 30,000 to 240,000 litres. - Outdoor installations, where a chemical-resistant body matters. ## Where it is used - Hotels - Leisure facilities - Residential developments - Aquatic centres ## How it works A sand filter passes water down through a bed of silica sand, which holds back fine particles. Internal collector and diffuser assemblies, made of corrosion-resistant plastics, spread the flow evenly so the whole bed does the work. A multiport valve, top- or side-mounted, switches between six modes: filtration, backwash, rinse, recirculate, waste and closed. An integrated pressure gauge shows the filter's condition, and a manual bleeder valve purges air. The three sizes cover different loads. The 600 mm handles up to 240 L/min for smaller residential and commercial systems, the 750 mm up to 350 L/min for mid-size leisure and development systems, and the 900 mm up to 500 L/min for the largest aquatic and commercial systems. ## How it compares Sand filters and Regent media filters do different jobs. Choose by the size of system and the valve you want. - AquaShield sand filters: You need **high-flow clarity** for hotels, leisure or aquatic sites, with **six-mode multiport valve** and flow up to **500 L/min**. - [Regent Sediment 3072](https://sovereignwater.co.uk/products/regent-sediment-3072): You need to take **silt and suspended solids** out ahead of other plant, on a **metered valve** that backwashes by volume. - [Auto-Backwash Filters](https://sovereignwater.co.uk/products/auto-backwash-filters): You want a **smaller, automatic media filter** in 10 × 54 inch or 21 × 62 inch vessels. ## Installation and servicing Each vessel has a built-in anchoring base, a top- or side-mount multiport valve (1½, 2 or 2½ inch), an integrated pressure gauge and a manual air bleeder valve. Side-mount versions have a transparent lid. Silica sand is specified on order. The datasheet gives flow by vessel size but does not say which valve size goes with which vessel, and it does not list electrical or pressure figures. We confirm the vessel, valve and media for your system at survey. The survey is chargeable and is credited back if you go ahead. ## Questions and answers ### What sizes is AquaShield available in? Three: 600, 750 and 900 mm. ### How much water does it filter? Up to 240 L/min for the 600 mm, up to 350 L/min for the 750 mm, and up to 500 L/min for the 900 mm. ### What is it made of?
