Most craft canning lines utilize an electro-neumatic mechanism to actuate a dipstick or plunger style filling manifold.  These systems utilize a variety of sensitive moving parts and may be prone to excessive foaming for more effervescent products. Speeds are also limited by the jarring starting and stopping of the line for dipstick insertion and extraction. Inline Automation’s Rotary Counter Pressure Filler utilizes many of the same design principals found in industry standard rotary systems used in much larger commercial packaging houses.  The backbone of the system is a two stage counter pressure valve assembly that more gently fills cans by way of pressure differential rather than by simple mechanical gravity or force feed.  The result is a faster, smoother fill with no oxygen exposure.
