No, an axial flow fan is not designed to create much delta P, only flow. You need an radial flow device, like a vacuum impeller. As a rule of thumb when looking at impellers, flow is proportional to the impellers' width, while pressure is proportional to its diameter. So, for max holding power, use a large diameter, narrow impeller, or better yet, a 2-stage impeller system.
