Air nozzle complete SCHAERER Spare Parts 3370070970

An air nozzle assembly directs controlled streams of air into the steam wand of an espresso machine, blending air with steam to create the fine, stable microfoam needed for latte art and cappuccinos. Without this component, the wand would produce only scalding steam, unable to texture milk to the silky consistency baristas require.

The nozzle sits inside the steam wand, where it channels air from the machine's internal compressor or venturi system. As steam rushes past the nozzle's calibrated openings, it draws in air, emulsifying the two into a creamy froth. The operator positions the tip of the wand just below the milk's surface, then opens the steam valve; the nozzle's design determines how evenly the air is distributed, affecting the smoothness and volume of the foam.

To use, the barista attaches the nozzle to the wand assembly following the machine's service manual. Once fitted, the nozzle requires no further adjustment—its geometry sets the air-to-steam ratio. During operation, the wand is purged briefly to clear any condensation, then submerged in chilled milk. The steam valve is opened fully, and the wand is lowered or raised to maintain the correct depth until the milk reaches the desired temperature and texture.

Cleaning follows each use: the wand is purged again to expel milk residue, then wiped with a damp cloth. Periodically, the nozzle is removed and rinsed under warm water to prevent clogging from dried milk solids. No disassembly is needed beyond this routine.

This assembly is a direct replacement for SCHAERER espresso machines, ensuring compatibility with models that use the same wand configuration. It is listed in the spare-parts catalogue under steam-system components.
