There are two types of sand tanks in swimming pools: top out and side out, both of which belong to swimming pool filtration equipment. The top mounted one is more convenient to install and occupies a relatively small area. The installation of a side sand cylinder is more labor-intensive and occupies a relatively large area, but it also has its advantages. The height of the side sand cylinder is relatively low, so if the machine room is relatively low, a side sand cylinder can also be chosen.

The AP FB series side swimming pool filtration sand tank is manufactured using advanced technology. The interior of the sand tank has been improved for fluidity, resulting in better filtration efficiency. The surface is made of glass fiber wrapped to make the sand tank structure more stable. Glass fiber has properties such as chemical corrosion resistance, sun protection, and UV protection.

The AiPu Shi FB series side sand cylinder internal water distributor has been professionally designed to achieve uniform and stable flow velocity, and the efficiency of the underground drainage system is high. And the sand cylinder is easy to install, maintain, and upkeep; Equipped with eight horizontal discharge ports, it comprehensively processes impurities in filtered water to ensure high filtration efficiency; In addition, there is transparent glass for observing the clarity of the rinsing water; The bottom of the sand tank is stable and durable, making it the preferred filtration equipment for swimming pools, spa pools, landscape pools, and water parks.

Detail parts:
Six position multi-directional valve: integrates six major functions: Filter normal filtration, Backwash, Recirculate external circulation, Waste discharge, RINSE rinsing, and CLOSED closing. Easy and convenient operation. Attention: When operating this valve, the power supply of the water pump must be disconnected to prevent damage to the cylinder head.
Cylinder body: The cylinder body is made of fiberglass reinforced material wrapped around it, which is sturdy, wear-resistant, and corrosion-resistant; The uniquely designed water distributor can evenly and stably distribute water flow, and the large-diameter bottom sand discharge valve is easy to clean or replace the sand in the cylinder.
Precision pressure gauge pressure measurement system: The Epson series swimming pool filtration sand cylinder is equipped with a precision pressure gauge pressure measuring elastic element that has been specially processed to ensure stable and reliable performance of the precision pressure gauge. After being matched and debugged with a high-precision transmission mechanism, it can ensure accurate indication accuracy. If the pressure gauge reading on the filter sand cylinder is higher than 2.5kg/cm2 or above, the filter sand cylinder needs to be backwashed immediately
