What is a Primary Regulator?

Kegging is a fun way to dispense beer. If you are planning to build a small kegerator or dispensing from your homemade bar then it is crucial that you know about their components. One of the most important components to get your brew from the keg to a glass is a regulator. It functions by dispensing the gas tank at a specified pressure that you need. As the pressure of the Carbon dioxide or nitrogen tank is very high, the regulator allows you to control the amount of pressure that you think is appropriate in dispensing your homebrew.

There are different types of regulators that you can use in building your kegerator and one of them is the primary regulator. The primary regulator is a standard regulator that all homebrewers should use. It is used to regulate the Carbon dioxide or nitrogen. It has at least one gauge that features the pressure output of between 0 to 60 pounds or PSI. (more info below)

The primary regulator is connected to the gas tank directly. They also come with a safety relief valve and shut-off valve regardless of the brand or model. These are necessary so that the gas flow stops immediately before it goes to a dangerously high pressure. Having too much pressure within the regulator may cause the regulator to burst thus the need for safety features.

While primary regulators are used with one keg, you can still use it to dispense two kegs by using a 2-product primary regulator. This type of primary regulator includes 2 hose nipples so that two kegs can dispense beer using one gas source. You can also use triple gauge options to three kegs. However, if you plan on connecting more multiple kegs with one source, then using a secondary regulator is your best option.

If your aim is to build an average draft beer system, the go ahead and install a primary regulator. Happy kegging!
