Boilermaker Tough and Field Proven

The PANELHOG® Universal Air Powered Saw APS-438 is the complete, all around maintenance tool.

Effortlessly gliding along the 5 ft. steel EscoTrack System, which attaches to a boiler tube panel section using two weld tabs, this powerful saw makes both horizontal and vertical cuts.

After completing a horizontal cut, all you have to do for membrane removal is either remove the saw, rotate it 90° and reinstall it on the track, or for even faster membrane notching use the membrane removal bracket.

This system is faster and safer than torch cutting and there is no heat affected zone or further rework needed before end prepping.
