SunSun HW-302 – external filter up to 250l

HW series filters were created with the largest possible capacity in mind, guaranteeing the best filtration, while at the same time being easy to use and operate, ensuring trouble-free operation.

SunSun material quality:
The highest quality materials were used for the construction. The body, cover and other plastic elements were made of ABS, which is an amorphous material with high density.  It is characterized by high resistance to cracks and mechanical damage . The seals are made of rubber with an appropriate number of polyolefin chain connections, which are responsible for the appropriate flexibility and durability.  The materials and original casting forms guarantee the reliability of the filter  for which it was created. Manufacturers – “imitators” of filters with the same structure, of which there are many on the market, can envy the workmanship and quality and class of the SunSun brand product.

Tightness only in the original:
The effectiveness of tightness is complemented by a double closing system. The system is based on two pairs of clamps with different closing methods. One of the pairs provides pressure on the principle of a lever, guaranteeing tightness of the closure. A pair of these clamps also facilitates opening the filter cover. The second pair of clamps ensures a durable closure, even when lifting the full filter by holding the cover. These clamps are closed using the latch method. 

The filter has an “aqua-stop” system that blocks the flow of water  from the filter to the hoses. This valve allows the hoses to be disconnected from the filter cover. It is essential during all maintenance work. 

Quiet and efficient:
Silent operation is ensured by a pump with a high operating culture. The pump is based on a ceramic rotor, which allows it to work in sea water. It is enclosed in a tight and large filter cover, which additionally dampens the pump’s operation, and rubber feet dampens any vibrations.

Water inlet and outlet:
A tube with a safety basket draws water in the closest possible areas to the bottom. The length of this tube can be freely modified by additional tube segments. In this way, the filter sucks in impurities lying on the bottom, which are a common cause of silting the bottom and deterioration of water quality. The inlet has a sieve that protects against fish, shrimp, plants and other large elements from entering the filter.

The water outlet, thanks to the large number of pipes and fittings, can also be freely modified. It is done using a rain shower, which perfectly aerates the water, effectively replacing popular aerators. 

The filter is originally equipped with various filter media. 
Biological filtration ensures bio-ceramics of various porosity and bioballs. Ceramics and bioballs are a habitat for bacteria that reduce the concentration of NH3, NH4 and NO2 in the aquarium, while also affecting the health of fish and providing a natural nutrient for plants. 

Chemical filtration  is ensured by activated carbon, which perfectly binds metals and their compounds, humic substances, pesticides and metabolic products. It is a water clarifying and odor-reducing insert. Improves water quality, including biological filtration.

Mechanical filtration  is ensured by a sponge with the appropriate gradation. It removes all impurities from the water, clarifying the water from any dust, plant debris or small floating parts of the substrate.

Baskets for filter media can accommodate any filter insert depending on the needs of the tank.
