Praga Bobbin-Wound Filter, Filament-Wound Pool Filter.

The difference is only in the maximum operating pressure. Within the same size and velocity class, the two pressure classes are sold under separate codes. For example, on the Ø1050 mm body at 20 m³/h/m², the 2.5 bar code is 00687 and the 4 bar code is 09209. Filter area and flow rate stay the same; the class required by the line pressure is chosen.

A pressure gauge, an air bleed valve and a drain valve come with the body. The Ø400 mm filter lid is also included. The valve manifold system and the filter media are not included. If glass media is to be used, see the Active Glass Media product. If sand is to be used, it is also supplied separately.

The difference lies in the filter bed height and the velocity options. Praga has a 1 m bed height and comes in velocity classes of 20, 30, 40 and 50 m³/h/m². Oslo has a 1.2 m bed height and is sold only at 30 and 40 m³/h/m². In both ranges the body diameter is Ø1050-2200 mm and the pressure class is 2.5 or 4 bar.

The connection diameter is between Ø63 and Ø160 mm and increases as the flow rate rises. On the Ø1050 mm body it is Ø63 mm at 20 m³/h/m² and Ø90 mm at 50 m³/h/m². On the Ø1800 mm body at 50 m³/h/m², Ø140 or Ø160 mm is chosen. The diameter is determined together with the chosen velocity class.

The body is made of isophthalic polyester and fibreglass by the filament winding method. The filter bed height is 1 m, and there is a Ø400 mm lid on top. The same body construction is used in the 2.5 bar and 4 bar classes. As the filter media does not come with the package, the bed is filled on site with the chosen media.

There are seven body diameters: Ø1050, 1200, 1400, 1600, 1800, 2000 and 2200 mm. The filter areas are 0.87, 1.13, 1.54, 2.01, 2.54, 3.14 and 3.80 m² respectively. The Ø1200 mm body is sold in the 20-30 or 40-50 m³/h/m² velocity class. For each diameter, a separate model is chosen according to velocity and pressure class.
