Precision Ridgeless Double Portafilter Basket - 16/18gr (Special Order Item)

One of the exclusive "E&B" (Espresso and Brewing) products from I.M.S., this basket was specifically designed for the Kees Van Der Westen portafilters and group heads, but will work with any "standard" size 58 mm portafilter that's deep enough to accept the 24 mm height.

70 mm outside diameter at the rim, 60 mm body, for 58 mm diameter tampers. Ridgeless, with a flat bottom. The shape was created by I.M.S. to obtain the proper ratio between the base and height of the coffee puck in relation to capacity. The cylindrical flat bottom shape has been designed to exploit the whole coffee puck, which also facilitates drying and expulsion. I.M.S. perforation is exclusive and patented. This basket has a perforated area of 49 mm, optimized in relation to the shape of the filter, and every one comes with exactly 715 holes. The number and distribution of the perforated holes are designed to balance the delivery in relation to the height and shape of the filter and perforated area. Each hole has a diameter of 0.30 mm and are circular with a conical cross section. After being re-laminated and recalibrated, each basket is finished with a wet vibrofinishing by ceramic inserts and then dried with corncob. They are then refinished again with electropolishing to obtain a smooth surface resulting in a product with unmatched sanitary and non-contaminating qualities.
