In the world of filtration, there are many different types of equipment you can get to filter debris out of a system. These include basket strainers, Y-strainers, duplex strainers, single cartridge housings, multi cartridge housings, single bag housings, multi bag housings, and more. Today we will focus on single and multi bag housings. Deciding on a filter housing can be difficult, since these can be expensive pieces of equipment. This blog post will look at the pros and cons of both types of filter housings so you can make the right decision for your application!
Single Bag Housings
Single bag filter housings are great for small-scale applications that still need attention to quality. Single bag housings use one filter bag to remove dirt and debris, big and small, from fluid in a system. There are many different types of bags, made from all kinds of durable and absorbent materials. When the bag is full, it must be taken out and replaced. Luckily, filter bags are inexpensive and can be purchased in huge quantities, so running out is rarely a problem!
One of the only real downsides of single bag filter housings is the fact that liquid flow must be stopped to replace the bags. This can completely halt a system for a few minutes, but most small-to-medium sized applications aren't affected by stopping for changeouts. The primary benefit of single bag housings is that they are the economical option. They are less expensive, not to mention less complicated! Anyone can operate these housings, as they usually open at the top with a hinge or lever depending on the model.
Multi Bag Housings
Multi bag filter housings, as their name suggests, carry multiple bags at once. These are great for larger applications with high flow and a system that cannot be shut down. They lelt more fluid through a system at one time, sometimes using over 50 bags at once. This means 50 times the flow rate as a single bag housing. The best part about multi bag housings is that they can keep running while a bag is being replaced. Simply open up the closure, take out the full filter bag, and place it back in. You don't event need to stop flow through the housing!
The biggest difference between single and multi bag housings is price. Depending on make and model, multi bag housings can cost several times more than their single bag counterparts. To some, this expenditure may be necessary. This is especially true if the one purchasing the housing is looking for a filter for a process that runs 24 hours a day. When high flow and constant service are required, mutli bag housings are the perfect option.
The bottom line is that neither type of filter housing is flat-out better than the other. Certain housings just work best for certain types of applications.
