GEP has developed a unique filter shaft; the ‘Trident tank filter shaft’. The filter shaft is applicable for all tanks made of plastic and concrete rain water boreholes of GEP. The concept is the result of 15 years of engineering, recruiting and practical experience. The unique Trident tank filter shaft of GEP has the following properties and advantages:
– The Trident tank filter shaft scoveres over the synthetic manhole of the tank or concrete pit and is mounted with rubber grommets to realise an optimal sealing. It is a simple and time-saving solution, making the
usage of kit, welds or mortar something of the past.
– The sawable and telescopic shafts will instantly prove to be beneficial! The laborious placing of and/or masonry work on a manhole is no longer required. These shafts can be sawn or raised in no time.
– In addition, the shaft can be rotated against the tank, due to which fewer connection pieces are required.
– The shafts are extendable with extra connections, that can be quickly and easily applied.
– The cover is, subsequently, telescopic compared to the inner shaft. This way the cover can be precisely equated to the ground level. This can also be done at a later stage of the construction, when ultimately the garden is being created. This again will save you some fitting pieces, thus time and money.
– The cover set is rotatable against the shaft and the tank. During finishing applying grouting in paving, the joints can thus always be followed perfectly. This can also be lightly tilted to realise a perfect finish on slopes.
In short: the ‘Trident tank filter shaft’ with accompanying covers offers a telescopic, rotatable and extendable option that can be shortened. The extensive assortment of fitting covers offers an “invisible” and childproof covering for any situation.
