The 2 black button/links at the bottom of the coupon go here:
They also sell a 3.0. Was wondering if anyone has ever set one up for boards. Do they pull enough?
A quick Googling turned up this:
“This pump’s max vacuum of 10 Pascal is expressed in absolute pressure.
This number corresponds to 29.92 (relative) Inches of Mercury.”

29hg is way more than enough for surfboards.
Figured so. A couple of people have tried to scare me off of buying one. They want me to spend as much money as they did.
You could use the Harbour Freight Vacuum Pump however don't skip on the rest of the unit. (Mac Value, Presure Switch and other items you will need. The pump is pretty cheap and looks like a good deal. I used a more industrial pump (4.5 CFM's) that draws vacuum in 20 seconds and comes on ever 30 minutes for 20 seconds then turns off. I do my bagging at home away from the shop so I needed it quiet. The Harbour Freight Unit will work fine just set it up with some reserve tanks and Mac Value. I added a relay because of the 220V I run all my tools on in my garage. With 110V it there will be less wiring. It's really easy. I can do three boards at once. For single production the Harbour Freight unit is a good value.
Happy Building!
Kind regards,
Surfding

i’ve used that pump to do a few boards. works really well. i’d go w/ surfding’s suggestion and do the full setup w/ reserve tanks and switches, etc. my little pump smokes like a bitch b/c it runs the whole time.
