ErtelAlsop’s externally ported filters are designed for small to medium sized wineries, breweries, distilleries, and the food and beverage market in general. The ME line comes complete with 20 x 20 cm food grade NORYL plates which are also steam sterilizable. A dividing head is also an option, which allows for 2-stage (double) filtration. Double filtration allows for your product to pass through a coarse filter media, and then also through a polishing filter media while passing through the press only once. Not only does this save you time, but it also reduces the amount of product agitation and handling.
