Technical data

The following applies for all the models of
the device:
– The filters are supplied with a stainless
steel screen with a mesh size of 0.1 mm
(0.004 inch) as a standard.
– Nominal flow rate after backwashing at a
pressure loss of 2.9 (7.3) psi [20 (50)
kPa] as given in the corresponding table
– Maximum ambient temperature and
water temperature: 86 °F (30 °C)
– The water to be filtered must possess
quality of drinking water!

JUDO SPEEDY-LongLife
The nominal pressure denotes the pressure
class, according to which the filter must fulfill
the requirements of the DIN EN 13443-1
and DIN 19628 standards in Germany. The
maximum operating pressure is lower, in
order to ensure the optimum function of the
filter.
