    Hey everyone,

    First time poster, long time lurker... Hopefully there is an easy answer here that I am just not seeing.

    I am trying to pair a blower fan (of some sort) to my HEPA filter.

    The filter is 24"(w) x 24"(h) x 12"(d) and has a static pressure of 1.5 w.g.

    I will also be adding a pre-filter which has a SP of 0.2 w.g.

    So by my calculations I need 600 cfm (aprox) @ static pressure of 1.7 wg

    Will either of these fans work for this application. The inflatable blower seems like it would but I'm not sure. It has a max static pressure of 8 wg and cfm of 1000 but how do these to relate?

    I'm having a very hard time finding any companies that show fan performance curves and also deliver to canada. I've also called a few fan manufacturers and not having any luck getting through to anyone.

    let me know what you guys think, if someone has been through this already and has already bought a fan for a similar application. I am all ears!!

    Thanks
