Gruber GS1000 Vacuum Mixer

Eliminate air while blending solid surface matrix with a Gruber Vacuum Mixer! The GS1000 vacuum mixer has a aluminum tilting lid that swings up out of the way for easy movement of the pot. It comes with a 225 lb (102 kg) capacity, heavy-duty stainless steel mixing pot/vessel that can hold up to 16.8 gallons (63.5 liters) of solid surface matrix.
