HydroChem’s filtration partner, VAF Filtration Systems (USA), developed the patented bi-directional drive system that does not require electric motors, limit switches, gearboxes, hydraulic pistons or any external shaft seals.

Full details of the VAF range are available at here.

HydroChem supports the flagship V-Series automatic self cleaning screen filters. The cleaning cycle of each filter takes less than 15 seconds and does not interrupt flow or the filtration process.


V-Series can remove suspended solids from 1500 to 10 micron. Individual filters and preassembled filtration systems are used in applications for pre-filtration of membrane, ultra-violet and other micro filtration technologies, as well as applications for industrial water reuse, water and wastewater, cooling towers, seawater, river intake water, well water, groundwater re- injection ( frac water), irrigation and many more.
