MHW 3Bomber Impact tamper, Astra series

The Astra series from MHW 3Bomber uses all-metal materials as a base, which are combined with a dark colour scheme. The Astra series from MHW 3Bomber uses all-metal materials as the basis, which are combined with a dark colour scheme. The improved electroplating technology makes the unique black colour "Obsidian" possible.

Tamping compacts the coffee powder in the sieve to produce a firm and uniform coffee cake with a smooth and even surface. Correct tamping avoids the channelling effect and achieves an even extraction of all the coffee powder. This releases all the flavourings from the coffee.

The Astra Impact Tamper is a pressure-controlled tamper with a preset pressure of 13.6 kg. When the preset pressure is reached, a mechanical signal sounds as feedback and the tamper releases the pressure again. After several tests, MHW 3Bomber has established that at a constant pressure of 13.6 kg, the extraction rate is almost the same for different quantities of powder and different extraction times. The outer ring, which lies flat on the sieve support, ensures that the tamper is always pressed down vertically. The tamper is simply placed on top and pressed down, the spring pulls the base back up again.

This tamper fits perfectly on 51 mm portafilters.

The tamper has an ergonomic handle and sits comfortably in the hand. In addition, the base has concentric grooves, which means that more coffee powder comes into contact with the water, resulting in better extraction.

The entire tamper is made of high-quality materials. The handle and the middle section are made of an aluminium alloy, the base and the spring are made of stainless steel (SUS304). A replacement spring is supplied. The entire tamper can be dismantled and is therefore easy to clean.

With this tamper, perfect coffee extraction can be achieved when used correctly.
