Accessories

● Extension tube
The scope of supply of the standard version includes an extension
tube. An extension tube is available to raise the inspection opening
by up to 56 cm (top edge of final ring). Another tube can easily be
attached, but no more than two tubes should be assembled above
each other.
● Lifting handle
The lifting handle supplied with the standard version is 30 cm in
length. Lifting handles of 60 cm or 1 m in length are also available.
● Wall bracket
WISY provide a stainless steel wall bracket for internal roof drainage
pipes in industrial buildings, or for fixing in shafts. This bracket al-
lows the WFF to be safely secured to a vertical internal wall.
● Concrete rainwater storage tanks
WISY supplies a stainless steel wall bracket for attaching the WFF to
concrete rainwater storage tanks. A suitable concrete support must
be provided to ensure the vehicle loading capacity of the filter.
Seepage sieve
● Blind insert
The blind insert ensures that rainwater flows directly through to the
drain. It is inserted in place of the filter insert whenever the storage
tank needs to be put out of operation for the purpose of mainte-
nance or cleaning work.
● Soakaway sieve (maintenance part)
If the rinsing water is to be drained into a
soakaway system instead of the storm drain,
this sieve (mesh size 1.6 mm) is added to the
filter insert. It collects coarse dirt particles and
as a result it must be inspected, emptied and
cleaned regularily.
If this essential maintenance is not carried
out and water damage occurs as a result of
a blocked seepage sieve, we cannot accept
any liability.
