Trawl float | type 551 | buoyancy 3230g | orange

These floats are mostly used for fishing in deep waters. Because of the strong material the range of purposes is very wide.

Product details:

• 200mm diameter
• 21mm hole diameter
• impact strength 20kg/m
• 3230g buoyancy
• max. working depth 400m

The stated characteristics of the floats are laboratory tested as follows:

Maximum working depth: The pressure corresponding to the stated working depth is applied within a period of 30 minutes and is held for 4 hours at a temperature of 18°C. (1 bar = 10 m water pressure)

Impact strength: In a factory own test procedure at a temperature of 18° C an object with the stated weight is hitting the float from a height of 1,00 m. The float has to withstand this impact.

Buoyancy: The buoyancy is being tested in fresh water. In sea water the buoyancy will be slightly higher.

Quality control: according to ISO 9001.

Laboratory tests have proved that at lower temperatures the floats can withstand a higher pressure while the impact strength is reduced. At higher temperatures this observation is contrary.
