ENGINEERING CORPORATION S.r.l. have been designing and manufacturing (painted, galvanised or stainless) steel filters for years for the most varied sectors, among which: drinking waters, mineral waters, thermal waters, swimming-pool waters and industrial waters. ENG EHR/UNI/DIN/P filters have been designed for long-lasting operation.

Their main features are: - presence of a diffusion plate - compliance with UNI-DIN Standards - catalyzed and multi-layer filtering materials - visual inspection door and no. 2 side manholes + no. 1 manhole for subplate inspection - disinfection diffusor - mixed backwash, air-water, for big diameters - constant presence of no. 5 valves on the front battery, both in hand and automatic versions.

ENG EHR/UNI/DIN/P filters are based on the principle of volumetric and not surface filtration. Thanks to the accurately selected filtering materials, the filtering action is exerted on the active sites of each single granule, where, because of an accurate reckoning of water radical speed, self-flocculation processes are enhanced.

Because of these features, ENG EHR/UNI/DIN/P filters are used in the most varied fields of water treatment. An accurate selection of the building materials and a special care given during welding and passivation processes make ENG EHR/UNI/DIN/P filters strong, effective and designed to last.

ENGINEERING CORPORATION S.r.l. also manufacture a small range of swimming-pool plastic filters in the ENG EHR/ISO/VRT/T and ENG EHR/ISO/VRT/S series with diameters between 350mm and 850 mm, and delivery rates from 5 to 29 cubic metres/h. A 6-way standard monovalve is envisaged for the whole range of plastic filters.
