Multi Bag Filter Vessels

Allied Filter Systems is able to offer multi bag vessels containing 3 to 24 bags for applications requiring high flow rates or a large filtration surface area. Flow is split equally through each filter bag, ensuring an even distribution of solid loading.

Multi bag vessels are available with a choice of inlet and outlet orientations and are constructed from stainless steel 304 or 316L. Some models are available in carbon steel. Standard pressure ratings are 6 Bar or 10 Bar, but higher pressure ratings are available on request. Optional features are available to meet all customer requirements.

We offer two designs with a selection of three different closure types:

Designs

  • Dome lid: Filter Bags are held in position by individual bayonets.
  • Flat lid: With individual fluid distribution pipes (4 bag only). Filter bags are compressed by the lid, ensuring excellent 360o seal. This design reduces the amount of residual liquid in the lid, minimising product loss and possible spillage.

Closure Types

  • Quick Closure system allowing a fast bag changeout, with weightless feel spring assisted counterbalanced hinged lid.
  • Bolted lid with weightless feel spring assisted counterbalanced hinged lid.
  • Bolted lid with Davit arm

Additional Information

The quick closure system  was developed for multi bag vessels to eliminate the need for swing bolts, which considerably decreases the time required for filter bag changeout.

The system consists of a heavy duty precision engineered clamp, an opening wheel with counter screw, and a safety lock attached to the housing vent.

To change the filter bags, first the safety lock is released, simultaneously venting the filter housing. Turning the hand wheel then opens the clamp. The hinged lid can then be lifted. The spring assisted counterbalance system gives the lid has a weightless feel. The filter bags can then be changed, and the reverse procedure is carried out to close the housing.

The hinged lid design minimises the installation space required compared to davit lid models.
