Syn-Pac E Bag Filter
Syn-Pac E Bag Filter
Tri-Dim’s SYN-PAC E filters utilize an advanced dual layer meltblown media. The medias dual layers allow for depth loading – that is managing the dirt by capturing larger particles on the ‘prefilter’ layer and having the second layer focus on removing the smaller ‘target’ particles. Depth loading results in much higher dirt holding capacity – allowing for longer service life. The final layer of the SYN-PAC E media is a spun bonded scrim backing that supports and protects the filter media. The combination of high removal efficiency and long service life makes Tri-Dim’s SYN-PAC E a great value.
