Brew-Boss Pro COFI Mash Infusion Filter for 54 Gallon Kettle


The Brew-Boss COFI filter is an exciting new technology that optimizes the efficiency of Brew-In-A-Bag (BIAB) type brewing. The filter is manufactured from 304 grade stainless steel mesh which holds the grain during the mash process, but allows water to flow through. Support legs allow the filter to sit above the heating elements and are 3-1/2 inches tall.

This item is provided for brewers to add to their existing (Brew-Boss or other Manufacturer) breweries and includes the following items:

  • Mesh basket with 3.5" long feet to clear heating element.
  • Mesh Cover with Stainless Steel Clamps and Lifting Rings
  • 3x Perforated Center Infusion Tubes
  • False Bottom with 3x Threaded Infusion Tube Mounts
  • 3x Stainless Elbow Fittings for Top of Infusion Tubes
  • Stainless Lift Plate with Chains and Coupler
  • 3x End Caps for retaining lift plate when removing filter
  • Type C Camlock Female Fitting to attach to Deluxe Accessory Port
  • 4-Way Coupler with male Camlocks for Infusion Tube Connections
  • 3x High Flow Female Camlocks for 4-Way Coupler
  • 3x 12" Silicone Brewery Grade Tubing
  • Lifting Sling for lifting filter without grain squeeze.

Three central infusion tubes, that are perforated with a series of flow-matched holes, extend all the way to the bottom of the filter.
During the mash cycle, water is continuously pumped from the bottom of the kettle to the top of the filter, into the central infusion tubes, where it is forced through the grain bed. Water passing through the grain bed flows out of the filter to the bottom of the kettle. This Center Out Forced Infusion (COFI) technology assures that all the grain is in constant contact with the mash water and that there are no dead spots. No stirring is required as the system is self agitating and efficiency is thereby optimized. The COFI filter is also very easy to clean, simply invert it in a sink and spray it with your sprayer! Because it is made of stainless steel, it will not rust and will last indefinitely.

The central infusion tubes are also connected to a false bottom. After mashing is completed, the elbow infusion tube assemblies are removed and a special lifting plate is installed. When removing the filter, the filter is lifted by the lifting plate assembly. This brings the false bottom towards the fixed cover, allowing the weight of the filter to squeeze the grain. This squeezing action extracts much of the trapped sweet wort from the grain.
