Consistent Carbonation Quality from the McCann's E400397-PP Big Mac Carbonator

At the heart of this unit is a durable rotary-vane brass water pump that delivers atomized water directly into the carbonation tank. This atomization process increases the surface area of the water, allowing CO2 to dissolve more efficiently and produce properly carbonated beverages with every pour.

The pump also includes a built-in 100 micron strainer that keeps debris out of the system, protecting both carbonation quality and internal components. A 180 PSI pressure relief valve adds another layer of protection, preventing over-pressurization that could compromise your carbonated output.

How the McCann's Fastflow Big Mac Carbonator Keeps Up During Rush Hours

Need to keep multiple dispensing stations running at once? The Big Mac's two soda outlets and 180-ounce (5.3 liter) tank give you the capacity to serve high volumes without falling behind. The 100 GPH (378 LPH) rotary-vane brass pump refills the tank quickly, so you're never left waiting during peak periods.

Pair that with a 1/3 HP motor running at 1725 RPM, and you've got a carbonator that powers through your busiest hours without breaking a sweat.

Diamond Brite Stainless Steel Construction on This McCann's Big Mac Soda Carbonator

The Diamond Brite stainless steel tank resists corrosion and cleans up easily, even after years of heavy use. This isn't a unit that degrades over time. The stainless steel body holds 180 fl. ounces (5.3 liters) of carbonated water, ready to dispense through two soda outlets simultaneously.

Specially designed probe electronics resist damage from amperage spikes, giving you greater reliability even in environments with inconsistent power. A liquid-level float assembly and heat sink probe cap work together to keep the system running without interruption and extend the overall service life of the unit.

A Two-Piece Probe Design That Cuts Your Service Time

Servicing a carbonator shouldn't mean shutting down your entire beverage system. The Big Mac's exclusive two-piece probe design lets you remove and test the probe without depressurizing the tank and without shutting off CO2 or water. The fully encapsulated electronics package is just as easy to pull out for testing and troubleshooting.

Testing the probe is straightforward:

Remove the probe from the unit
Pass a magnetic screwdriver tip across the lower end of the electronics tube
If the reed switch closes, the motor starts, confirming proper function

This design means faster diagnostics, lower service costs, and less time with your system out of commission.

Backflow Protection and Safety Compliance Built Into Every Unit

Every Big Mac Carbonator ships with an Anderson Brass ASSE 1022-specified backflow prevention device already included. This protects your water supply from contamination and meets the requirements of local plumbing codes.

The unit is also certified compliant with California AB-1953 and Vermont Act 193 for low-lead standards. You'll also find UL and NSF certifications, along with a California Low Lead Qualified designation. Proudly Made in the USA.

Fitting Connections on the Soda Gun Bottle Big Mac Carbonator

The Big Mac uses standard fittings that connect to most existing beverage lines:

1/4" male flare for the CO2 inlet
3/8" male flare for the water inlet
3/8" male flare for the soda water outlet(s)

Before ordering, confirm that these fittings match your current setup to avoid adapter costs and installation delays.
