The Brew-Boss #COFI filter is an exciting 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. The filter is 13 inches in diameter x 13.5 inches high. The support legs allow the filter to sit above the heating element and are 2-1/2 inches tall. This brings the total height of the unit to 16 inches. The 90 degree barbed elbow at the top adds another 1-1/2 inches, for a total overall height of this filter with the barbed fitting installed of 17.5 inches. Make certain your kettle is tall enough to contain this filter with the cover on. The filter can hold approximately 20 pounds of crushed grain. This amount depends on the crush and the grain.
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 2.5" long feet to clear heating element.
- Mesh Cover with Stainless Steel Clamps and Handle
- Center Infusion Tube
- False Bottom with Threaded Infusion Tube Mount
- Stainless Elbow Fitting for Top of Infusion Tube
- Stainless Lift Ring Adapter
- Type C Camlock Female Fitting
- 12" Silicone Brewery Grade Tubing
A central infusion tube, that is perforated with a series of flow-matched holes, extends 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 tube, 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 tube is also connected to a false bottom. After mashing is completed, the elbow fitting at the top of the COFI filter is exchanged with a lifting ring. When removing the filter, the filter is lifted by the lift ring. 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.
