Duct blast

GW

Dusted off the old blaster this week, just barely squeaked under the 4% leakage at 25pa rule (4 cfm per 100 Sq ft of living space at 25 Pa). It's a bit of a pain when you have boxes in plaster and lath.

It looks brand new!

I don't use it often, most of our work is changeout stuff.
