    Caleffi has a good selection of DirtMag seps. Various sizes and connections, brass or composite.

    We just introduced the XF extra filtration. It has a fine mesh inside like a y strainer. Turn the grey top and brushes inside wipe it clean, magnet in the bottom. Vertical or horizontal mount.

    The Caleffi’s do not need to be opened up to clean, pull the magnet and flush out the bottom.

    Can take a look a adey magentic dirt seperators . I like them because they come w isolation shut offs the magentic element pulls out for inspection ,so you can see what your gathering and if your fluid is getting cleaner over just a flush . I also like them because it makes it quite easy to addd water treatment to the system without having to use a pump. I use it to add sentinel treatment to my systems and to also check fluid condition . I also have used Caleffi dirt seperators and hydro seperators and found there product top notch but have also used a the purpor 5 in 1 magentic hydro seperators and really liked it absolutely nothing wrong w Caleffi I use a lot of there other products prv ,backflows and mixing valves amoung alt of there other products never had a issue w Caleffi stuff . Peace and good luck clammy
