Smarter Packaging. Smarter Business.

Introducing the future of valve bag filling. With the Greif-Velox VeloVac vacuum packing systems, customers get reliable, repeatable, dust-free bagging of ultra-light materials like carbon black, fumed silica, and pigments. This cutting-edge technology removes excess air from the bagging process allowing for twice as many bags to be stacked per pallet compared to standard valve bag filers, saving up to 75% on shipping costs..


Vacuum Filler

  • The VeloVac is best for ultralight powders with high air-retention.
  • Safest and cleanest environment from completely sealed process
  • Fills up to 50 bags per hour (each spout)
  • Manual to fully automatic versions available

Pneumatic Filler

  • Suitable for powders, fine-grit, granules and product-mixes
  • Residual emptying system reduces changeover time by 80%
  • Fills 400 bags per hour (each spout)
  • Suitable for paper, PE or PP-woven bags

Features and Options

Precision Weighing & Filling

ValvoControl saves over 100 lbs per 1000 bags by reducing overfill “give-a-way”. Weigh cells are integrated into the filling carriage instead of the entire filler like most competitors providing maximum control with a secondary check weigher available if desired.

ValvoDetect comparison

99.5% Closure Reliability

ValvoDetect optical measuring system ensures that faulty bags can be detected and ejected at two points in the bagging process before they are placed on the pallet.

Closeup of ValvoSeal valve bag welds

60% Stronger Seals

Patented ValvoSeal welds valve bags securely and absolutely dust-free using ultrasound. The welding uses “waffle pattern”, which enables absolute tightness and keeps the valves securely closed during further processing and transport.

ValvoMat on white

99.7% Placing Rate

Innovative ValvoMat bag separation with forced pre-opening of the bag valve ensures minimal manpower and downtime. Different bag sizes and designs are compatible.

VeloPack robotic bag handling on white

Robotic Bag Handling

Improve quality and capacity while reducing staffing requirements. Compact fully integrated VeloPac transfer robotics transfers and palletizes at 1650 bags per hour. Provides a smaller and lower cost automated options compared to layer palletizing equipment.

Quick Clean closup

Quick Clean

Featured on the pneumatic filler, this easy access design allows cleaning and sanitization on most common materials in under 60 minutes. Boasts frequent and fast changeovers.

Double the packaged bulk density of light materials like carbon black without damaging microstructure. Proprietary equipment and controls draw a vacuum through the valve bag while filling creating the cleanest, most compact and stable bag available. Bags will not pick up moisture and remains easy to empty.
