- Air Powered Vacuum Press Kits – Project: V4TM Mini Auto-Cycling Venturi Vacuum Press Kit Auto-Cycling 2’ x 4’ 2’ x 2’ .5 CFM 25.5” Hg 1,750 lbs per square foot Yes (via vacuum controller) .8 CFM @ 80 PSI 1.2 CFM @ 90 PSI 68 dB 262 seconds 4 2 to 3 hours PVC Cement $308.50 Yes, w/ optional add-on kit Yes Downloadable PDF Great for very small compressors. The kit is easy to build and ultra-reliable. It’s not as fast as some users prefer and has a lower performance-to-cost ratio. Auto-Cycling 4’ x 4’ 2’ x 4’ 1.2 CFM 25.5” Hg 1,750 lbs per square foot Yes (via vacuum controller) 1.8 CFM @ 80 PSI 2.2 CFM @ 90 PSI 68 dB 118 seconds 4 2 to 3 hours PVC Cement $308.50 Yes, w/ optional add-on kit Yes Downloadable PDF Great for small compressors. It’s very easy to build and of course it’s ultra-reliable. Faster than the Mini version but not as fast as the other kits offered here. Auto-Cycling 4’ x 9’ 4’ x 4’ 3.2 CFM 25.5” Hg 1,750 lbs per square foot Yes (via vacuum controller) 4.8 CFM @ 80 PSI 5.5 CFM @ 90 PSI 68 dB 66 seconds 4 2 to 3 hours PVC Cement $318.50 Yes, w/ optional add-on kit Yes Downloadable PDF Very reliable and easy to build. Excellent vacuum speed at a super low cost. Requires a small to medium size compressor but it’s very efficient with the air. Auto-Cycling 4’ x 15’ or 6’ x 10’ 4’ x 6’ 5.5 CFM 25.5” Hg 1,750 lbs per square foot Yes (via vacuum controller) 7.8 CFM @ 80 PSI 9 CFM @ 90 PSI 68 dB 38 seconds 4 2 to 3 hours PVC Cement $393.50 Yes, w/ optional add-on kit Yes Downloadable PDF This version of the kit is very fast. It’s even faster than a 5 CFM electric vacuum pump. Requires a decent size air compressor and uses 7.8 CFM of air to create vacuum. Auto-Cycling 6’ x 15’ 4’ x 9’ 9 CFM 25.5” Hg 1,750 lbs per square foot Yes (via vacuum controller) 12.5 CFM @ 80 PSI 14 CFM @ 90 PSI 68 dB 25 seconds 4 2 to 3 hours PVC Cement $423.50 Yes, w/ optional add-on kit Yes Downloadable PDF A system like this can handle almost any veneering project that you can imagine. Requires a large air compressor and uses 12.5 CFM of air to create vacuum.

If your compressor will allow it, spend an extra 10 bucks to get the “Plus” model. It’s a very worthwhile upgrade. This is the kit that gives you the most bang for your buck. This is one of my favorite vacuum presses. The upgraded parts cause a jump in price but overall, this is a very cost-effective vacuum pressing system. The 9 CFM venturi is ridiculously quick. Similar high- speed systems can cost more than twice as much.
