Quick and safe opening and closure filter vessel.

All our dual cartridge and bag filter units are manufactured including our own unique Rudi quick opening and closure. This complete new opening/closure system allows the filtration operator to quick and safe open / close the filter vessel for change out of filter consumables.

Almost all of the cartridge filter units used in oilfield operations do have a flat lid with swing bolts and (eye) nuts. This traditional old design caused many issue’s with closing and opening the filter lid. Like lost nuts, damaged threaded swing bolts.

HSE Issue’s with the traditional swing bolts closure.

  • It is difficult to position the lid to fit the swing bolt into the gap with using your hands close to the lid. Many fingers and hands have be injured between the heavy lid and top flange.
  • Tightening the (eye) nuts require all ways a tool.  As common knowledge, in Oilfield there is nothing such as a perfect fitting spanner on site. So screwdrivers, adjustable spanners and even hammers are used to tighten the eye nuts. This is causing a high risk of injuries.

In case the fluid batches are larger we recommend to use a filter press or vertical pressure leaf filter as pre-filter.
