The ________ filter, used for low pressure applications, has a removable cartridge that can be cleaned or replaced.

• A. Spin-on
• B. Inline
• C. Bag
• D. Mesh

Answer: (A)

The idea here is that in low-pressure systems, a filter can be designed so the filtering element itself is in a removable cartridge inside a housing. A spin-on filter packages that cartridge in a canister that threads onto the base, making it easy to unscrew, pull out the element, clean or replace it, and then screw a fresh or cleaned cartridge back in. This setup is especially convenient for low-pressure applications because it allows quick servicing without complex disassembly, while still providing effective filtration through a replaceable element.

Bag filters use a bag rather than a cartridge, mesh filters are just screens, and inline filters describe how the unit is installed rather than the servicing style. The spin-on arrangement specifically centers on a replaceable cartridge inside a removable canister, which is why it’s the best fit for this statement.
