  • ACCESSORIES - SPARE PARTS
  • The body and cover are machined directly from brass bar and are nickel-plated, with the safety valve being sealed to the pressure calibration with an anti-tampering system.

  • The connection is on the left or on the right side and has a front pressure regulation system

  • The high- pressure capsule is made with pin, shutter and a spring to AISI 304 standards ensuring a longer life span. The seal gasket is made in high resistance PTFE.

  • A connection system between the high-pressure shutter and the low-pressure membrane ensures operating pressure self-adjustment during adjusting screw and unscrewing.

  • Provided with a sintered bronze dual-protection filter: one on the cylinder connection injector (which can be inspected for cleaning) and the second inside the high-pressure capsule.

  • Different outlet fittings can be supplied separately upon request together with a place for reducer wall mounting .

  • 50 mm diameter pressure gauges.

  • Individual shockproof packaging with internal protection.

CALIBRATION 3/4.8 bar

MACRO CO2

In the CO2 version, calibration at 3 and 4.8 bar provides for Macro pressure reducers with 1 to 5 sampling stations. The reducer can be fixed to the wall with the aid of one or more stainless steel plates, sold separately upon request (See accessories). Stable connection between the high-pressure shutter and the low-pressure membrane allows users to self-adjust operating pressure on the reducer in the low-pressure chamber. Using the front control, the low-pressure chamber pressure reduces automatically.

CALIBRATION 7 bar

CARBONATORS VERSION

The version for carbonators at 7 bar for mixing with CO2 provides for Macro reducers from 1 to 5 sampling stations for different sampling levels and, if necessary, a station with a safety valve calibrated to 4.8 or 3 bar.

CALIBRATION 4.8 bar

MACRO NITROGEN

The Macro reducer is also available in the version for nitrogen with a high-pressure gauge from 0-400 bar and calibration at 4.8 bar. Ideal for dispensing wine and non-carbonated beverages, available with 1 or more sampling stations (maximum 5).
