Retrotec Blower Door Kit complete with:
DM2 Mark II digital manometer & automated fan controller,
2200 series fan
durable hard fan case
new nylon frame case
red cloth panel
cables and umbilical
This professional grade kit is in very good condition. This is everything you need to do blower door testing on residential and commercial buildings. $1800
This setup will enable you to test larger, leakier buildings than the Energy Conservatory's Minneapolis blower door because of its greater top flow rate of 6,300 CFM. You can also test very small or tight buildings because of the selection of 11 flow rings. To test small or tight houses with the Minneapolis blower door, you'll need to purchase expensive accessory flow rings.
The 2200 fan housing is double walled and has foam in between the walls, making it more durable. Also the protective hard fan case is included which is great if you travel with it. The frame case is nylon, which makes it less attractive to thieves than the rifle case shipped with other models.
