SunSun HW-603 - external pre-filter

The HW series pre-filters have been designed with maximum capacity in mind, ensuring the best filtration while maintaining simplicity in operation and the filter's performance, guaranteeing reliable operation. 

The filter is dedicated to any external filter with a flow rate from 250 l/h to 2500 l/h.

Using the HW pre-filter significantly impacts the cleanliness of the target filter as well as the clarity of the water. All mechanical impurities are trapped in the pre-filter, which is easier to handle than any external filter. The use of pre-filtration greatly extends the time between the need to check the main filter, thus streamlining and simplifying the operation of the filtration system. 

The construction utilizes top-class materials. The body, lid, and other plastic components are made of ABS plastic, which is an amorphous material with a considerable density. It is characterized by high resistance to cracking and mechanical damage. The seals are made of rubber with an appropriate number of polyolefin chain connections, which ensure the right elasticity and durability. The materials and original casting molds guarantee the reliability of the filter for which it was created. Manufacturers - "imitators" of filters with the same design, of which there are many on the market, may envy the execution and quality of the product from the brand SunSun.

The effectiveness of the sealing is complemented by the appropriate closing system. The system relies on the operation of four clamps that work on the principle of lever and catch, exerting a large clamping force on the filter lid, thus guaranteeing the tightness of the closure.

The filter is equipped with large hose connections with valves. The valves allow for closing the water circuit, and the valve connection system to the filter housing enables the disconnection of the valves along with the filled hoses from the pre-filter, allowing for maintenance work.
