MHW-3BOMBER 58mm Bottomless Portafilter — E61/La Marzocco, 18g

The MHW-3BOMBER 58 mm Bottomless Portafilter is designed for E61 brew heads and popular machines including Faema, Slayer, Synesso, La Marzocco (except KB90/Strada X), Rocket, Expobar, LaCimbali, Casadio, Rancilio, and Sanremo. The FlowLight series features an all-metal, two-tone build with two ears and ships with an 18 g filter basket containing 632 holes (0.3 mm) to reduce fines and keep extraction clean. A bottomless design lets you clearly see the shot to diagnose channeling and refine parameters; the removable basket makes cleanup easier. Note: issues like spurting/channeling are best addressed by adjusting tamping, distribution, and grind.
