To use, simply pour or couch your wet sheets/artwork. When you are ready to vacuum, cover the table with plastic sheeting to create a seal, turn on the pump and watch the magic! All the water literally gets sucked into the 5-gallon collecting tank. The 4 foot by 6 foot table has a polyethylene surface attached to a heavy duty painted steel frame, and is on wheels. The working height is 28”, and it comes with a powerful 1 hp vacuum pump with a pressure gauge so that you’ll always know when you’re getting maximum pressure. It includes a vacuum diffusing screen for the top surface. A plaque with directions for use are attached to the front of the table. Other sizes may be ordered.
