Geometric structure and large dirt collection chamber
The geometrical structure of DIRTCAL means that, inside it, the flow
speed is slowed down to help separate the particles of impurities.
The dirt collection chamber has the following features:
- It is located at the bottom of the device at such a distance from
the connections that the collected impurities are not affected by
the swirl of the flow through the screen.
- It has enough capacity to increase the amount of sludge stored
and therefore decrease the frequency of emptying/discharging it
in contrast to filters that need to be frequently cleaned.
- It is easy to inspect, by unscrewing the lower half from the valve
body for servicing the internal element to remove fiber or large
impurities.
